Description

  TECHNICAL FIELD The present invention relates to a charcoal manufacturing apparatus and a method for manufacturing a charcoal by producing a charcoal (and also a wood vinegar solution) by burning and burning a charcoal material such as rice husk, and in particular, reliably igniting the charcoal material. The present invention relates to a charcoal manufacturing apparatus and a charcoal manufacturing method.

  As a conventional charcoal manufacturing apparatus, there existed the thing of the structure demonstrated below, for example (refer patent document 1). The inside of the charcoal kiln main body opened on the top side (upper side) is divided by a grid plate, and the divided bottom side (lower side) is set as an air introduction chamber, and the top side is set as a grilled baking chamber. An air introduction part is provided in a side part of the main body of the charcoal kiln that communicates with the air introduction chamber, and an ignition port for injecting seed fire is provided in a side part in the vicinity of the top peripheral edge of the sushi grilling room. Furthermore, a canopy for closing the top opening is placed on the top side of the main body of the charcoal kiln. In addition, a chimney fitting portion for connecting the chimney is provided in a portion near the peripheral end of the canopy or in a side portion near the top peripheral edge of the charcoal kiln book.

  The main body of the charcoal kiln has a substantially cylindrical shape, and the canopy has a substantially disk shape. When the side surface portion provided with the ignition port and the air introduction portion is located at a rotation angle of 0 ° in the top view (top view) circumference. The chimney fitting portion is disposed at a portion having a rotation angle of 180 °. Therefore, the igniter and the chimney are arranged so as to form a central angle of 180 ° with respect to each other on the circumference as viewed from above.

  In the conventional charcoal manufacturing apparatus having such a configuration, after filling the charcoal material such as rice husk from the top opening of the charcoal kiln, the opening is closed by a canopy. Next, a seed fire is introduced from the igniter to ignite the uppermost layer of the charcoal material. In the uppermost layer of the charcoal charcoal material, combustion accompanied by flame occurs at the beginning of ignition, but when the ignition port is shielded and air is not supplied from the ignition port, sushi roasting that does not generate flame starts.

  Then, as the air supplied from the air introduction part is obtained, the sushi grill layer moves from the top side to the bottom side of the main body of the charcoal kiln. The soot rises through the layer that has already been baked and made into charcoal and is discharged from the chimney.

  Eventually, when the grilled layer reaches the lowermost layer of the charcoal material, the air introduction part is shielded. As a result, air is not supplied to the sushi grill layer, the charcoal kiln body functions like a fire extinguisher, and fire extinguishing is started. As for the prior art that shields the air introduction part for fire extinguishing, for example, an automatic fire extinguishing device that automatically detects and shields the firewood layer reaching the lowest layer of the charcoal material by a combustible member. Some are provided (see Patent Document 2).

  However, in the conventional charcoal production apparatus, when the charcoal material is ignited, the fire may disappear in the uppermost layer of the charcoal material, or the entire uppermost layer of the charcoal material is not ignited. There existed a subject that the part which will remain with a firewood charcoal material may be produced.

  When the seed fire is thrown from the ignition port, the part of the top layer of the firewood charcoal material that has been initially fired begins to burn, and mainly air is supplied from the ignition port, It spreads over the entire top layer. However, the igniter is provided in one part of the side surface of the main body of the charcoal kiln (and therefore partly in the circumference in the top view), the opening area is small, and the openings are not evenly arranged in the top view. Due to the shortage of supply or the generation of airflow due to the inflow of wind from the chimney, the fire may disappear on the way, or it may not spread over the entire top layer of firewood. In addition, rice husks and the like used as a charcoal material are generally difficult to burn, which causes such failure in ignition and incomplete ignition.

  In order to improve the ignition failure and incomplete ignition as described above, the operator raises the canopy by hand at the time of ignition, or puts a piece of wood etc. between the canopy and the top side periphery of the charcoal kiln body. It is conceivable to put a gap between them. However, in such a method where each individual worker makes an emergency, the gap formation is caused by the worker's sense and the variation in the thickness of the piece of wood. There were things that could be ignited and some things that couldn't be done.

  The charcoal producing apparatus of Embodiment 1 of the present invention includes a charcoal kiln 100, a charcoal kiln support mechanism 200, a canopy 300, a chimney 400, a chimney strut 500, a wood vinegar container 600, and an auxiliary instrument 700. It has. The charcoal manufacturing apparatus according to the first embodiment sequentially burns and burns the charcoal material filled in the charcoal kiln 100 from the top side to the bottom side to produce charcoal, and also uses a wood vinegar liquid (crude wood vinegar). Liquid).

[Scoal kiln 100]
The charcoal kiln 100 includes a charcoal kiln main body 110, a grid plate 120, an air introduction unit 130, and a plurality of hooks 140 (140a, 140b, 140c, 140d).

  The charcoal kiln body 110 is a substantially cylindrical kiln having an open top (upper side), and is made of, for example, stainless steel or iron. A grid plate 120 is stretched inside the charcoal kiln body 110. The grid plate 120 divides the inside of the charcoal kiln body 110 into a bottom (lower) air introduction chamber and a top steaming chamber.

  A substantially square tube-shaped air introduction portion 130 that leads to the air introduction chamber is provided on a side surface portion near the bottom surface of the charcoal kiln main body 110. The air introduction part 130 can be opened and closed by a lid provided at the protruding end. Unlike the conventional charcoal manufacturing apparatus, the charcoal manufacturing apparatus according to the first embodiment does not require an ignition port on the side surface of the charcoal kiln body 110.

  A hook 140 (140a, 140b, 140c, 140d) is provided on a side surface portion in the vicinity of the top peripheral edge of the charcoal kiln body 110. Assuming that the rotation angle of the part of the air introduction part 130 is 0 ° on the circumference of the top view (top view), the hook 140a is at the same rotation angle 0 ° as the air introduction part 130, and the hook 140b is 90 ° rotation angle. The hook 140c is provided at a position with a rotation angle of 180 °, and the hook 140d is provided at a position with a rotation angle of 270 °. That is, a total of four hooks 140 are arranged such that the center angles formed by two hooks arranged adjacent to each other are 90 ° in a top view. These hooks 140 serve to fix the canopy 300 placed on the top peripheral edge of the charcoal kiln main body 110.

  In addition, for example, a total of three hooks are arranged so that the central angles formed by two hooks arranged adjacent to each other are 120 °, and two center angles formed by each other are set to 180 °. It is also possible to arrange hooks, or arrange a total of six hooks so that the central angles formed by two hooks arranged adjacent to each other are 60 °.

  The hook 140 is operated to the release position by the operator, for example, when the top cover 300 is removed and the top opening of the charcoal kiln body 110 is released. In this release position, even if the canopy 300 is placed, the action claw of the hook 140 is in a position away from the peripheral end of the canopy 300. Therefore, the canopy 300 is not restrained by the hook 140 at all.

  Next, when an operating claw is hung on the peripheral end portion of the canopy 300 placed by the operator and the hook 140 is operated from the release position to the unlocking position, the canopy 300 has a play on the charcoal kiln main body 110. It will be like that.

  When the operator operates the operation claw of the hook 140 from the unlocked position to the locked position, the operating claw of the hook 140 urges the peripheral end of the canopy 300 downward (toward the charcoal kiln main body 110 side). Then, the canopy kiln main body 110 is brought into contact with the top peripheral edge portion, and the canopy 300 is fixed on the charcoal kiln main body 110.

[Steaming charcoal kiln support mechanism 200]
The charcoal kiln support mechanism 200 supports the charcoal kiln 100 in a hollow position by two support shafts. These two support shafts are provided at substantially the center position of the side surface in the cylindrical axis direction of the charcoal kiln main body 110. Further, these two support shafts are provided at a position where the center angle between them is 180 ° when viewed from above. Each support shaft is provided at a position where the central angle formed with the air introduction part 130 is 90 ° in a top view.

[Canopy 300]
The canopy 300 is a substantially disk-shaped lid that is detachably mounted on the top peripheral edge of the charcoal kiln main body 110 and closes the top opening of the charcoal kiln main body 110. A substantially cylindrical chimney fitting portion 310 is provided near the peripheral end portion of the canopy 300 and at a position shifted from the center of the canopy 300 in a top view. The chimney 400 is detachably connected to the canopy 300 by inserting the chimney 400 into the inner peripheral side surface of the chimney fitting portion 310. It is also possible to adopt a configuration in which the inner peripheral side surface of the chimney 400 is inserted into the chimney fitting portion 310.

  The canopy 300 is placed on the charcoal kiln main body 110 so that the chimney fitting portion 310 is positioned at a rotation angle of about 180 ° on the circumference as viewed from above. Therefore, when viewed from above, the central angle formed by the chimney fitting part 310 of the canopy 300 and the air introduction part 130 of the charcoal kiln body 110 is about 180 °.

[Chimney 400]
The chimney 400 includes a chimney main body 410 and a chimney connection part 420. The chimney body 410 has a substantially long cylinder. The chimney connection portion 420 has an L-shaped substantially cylindrical shape. The chimney main body 410 is connected to one end of the chimney connection portion 420 at a side surface near the bottom thereof. The other end of the chimney connection portion 420 is removably inserted into the chimney fitting portion 310 of the canopy 300. The chimney 400 discharges the soot generated in the charcoal kiln 100 by sushi-burning of the charcoal material, and efficiently cools the soot inside, thereby generating dew condensation.

  The chimney main body 410 can be rotated around the chimney connection part 420 at the connection site with the chimney connection part 420. The chimney main body 410 is disposed so as to be inclined so that the longitudinal direction forms an obtuse angle with the vertical direction (makes an acute angle with the installation surface of the charcoal manufacturing apparatus).

[Chimney strut 500]
The chimney strut 500 is installed between the top side of the chimney main body in the longitudinal direction and the installation surface of the charcoal manufacturing apparatus, and supports the chimney main body 410 that is inclined. Note that one or a plurality of cooling holes are provided at a substantially intermediate position in the longitudinal direction of the chimney main body 410.

[Wood vinegar container 600]
The wood vinegar container 600 is suspended from the bottom of the chimney main body 410. The bottom of the chimney main body 410 is provided with a pyroligneous liquid drop hole, and the pyroligneous acid container 600 is provided so as to be located directly below the pyrogenic acid liquid drop hole. The wood vinegar liquid that is highly condensed on the inner surface of the chimney body 410 by the inclined arrangement of the chimney body 410 and the cooling holes provided in the chimney body 410 is dropped from the vinegar droplet lower hole and stored in the wood vinegar container 600. It is done.

[Auxiliary device 700]
The auxiliary instrument 700 includes a collar portion 710, a projection portion 720, and a handle portion 730. This auxiliary instrument 700 is an instrument that is independent from the charcoal kiln 100 and is provided with a protrusion 720 on one surface of a substantially disk-shaped collar 710 and a handle 730 on the other surface of the collar 710. It is provided.

  The protruding portion 720 is formed with a tapered portion 725 that gradually decreases as the distance from the flange portion 710 increases. The projecting portion 720 includes a tapered portion 725 that gradually narrows from the base side (the flange portion 710 side) toward the projecting end side. The tapered portion 725 has, for example, a substantially conical shape or a substantially pyramid shape. .

  This auxiliary instrument 700 constitutes the ignition assisting means of Embodiment 1 of the present invention. The ignition auxiliary means of the present invention, when igniting the charcoal material filled in the charcoal kiln 100 from the top side, throws the fire type between the charcoal kiln 100 and the canopy 300 by shifting the canopy 300 to the top side. After forming the substantially ring-shaped gap S1 for igniting and igniting the above-described charcoal material, the gap S1 is eliminated by returning the position of the shifted canopy 300 to the original position so that the top opening of the charcoal kiln 100 is opened. It will be closed.

  More specifically, when the auxiliary instrument 700 ignites the charcoal material, the protrusion 720 is sandwiched between the canopy 300 and the top peripheral edge of the charcoal kiln 100, so that the substantially annular gap S1. After the firewood charcoal material is ignited, the gap S1 is gradually narrowed and closed by being pulled out from between the canopy 300 and the top peripheral edge.

  The protrusion 720 of the auxiliary instrument 700 is located between the peripheral end of the canopy 300 and the top peripheral edge of the charcoal kiln main body 110 and at a position where the rotation angle is about 0 ° on the circumference when viewed from above (chimney fitting part A substantially annular gap S <b> 1 is formed by being inserted at a position where the central angle formed with 310 is about 180 °. Next, the operator pulls the handle portion 730 of the auxiliary instrument 700, and the auxiliary instrument 700 moves away from the center of the canopy 300 in a top view, and the taper portion 725 of the auxiliary instrument 700 has the canopy 300 and the charcoal kiln body. As the space 110 is slid, the gap S1 gradually decreases. When the protrusion 720 of the auxiliary instrument 700 is completely extracted, the top opening of the charcoal kiln main body 110 is closed by the canopy 300.

  That is, the auxiliary instrument 700 forms a substantially ring-shaped gap S1 for dropping the seed fire between the canopy 300 and the top peripheral edge of the charcoal kiln body 110 when the charcoal is ignited. It plays the role of igniting the entire top layer of the material. In addition, the auxiliary instrument 700 plays a role of closing the gap S1 gradually and closing the top opening of the charcoal kiln main body 110 without impacting the chimney 400 when shifting to the charcoal grilling. Furthermore, the auxiliary instrument 700 is placed on the peripheral edge of the chimney fitting part 310 when extinguishing the charcoal, and serves to shorten the extinguishing time of the charcoal.

  The procedure for producing the charcoal and the pyroligneous liquor using the apparatus for producing charcoal of the first embodiment will be described below.

[Procedure for filling charcoal material]
First, the operator removes the canopy 300 from the charcoal kiln main body 110 (see FIG. 2A). Then, the charcoal material is accumulated and filled in the fired roasting chamber of the charcoal kiln main body 110 so as to be pushed in from above. At this time, the screws of both support shafts of the charcoal kiln support mechanism 200 are loosened so that the charcoal kiln main body 110 can swing with both support shafts used as swing shafts. That is, the cylindrical central axis of the substantially cylindrical charcoal kiln body 110 can be inclined with respect to the vertical direction. The operator tilts the charcoal kiln body 110 so that the charcoal material can be easily put, and fills the charcoal kiln body 110 with the charcoal kiln body 110.

  For example, rice husk is used as the charcoal material. The moisture content of the entire firewood charcoal material is preferably 10% (weight%) to 35%, for example, and the optimum value is 20% to 25%. As described above, the moisture content of the entire charcoal material is 10% to 35% because the recovery of the pyroligneous liquor may be reduced if it is 10% or less, and the roasting may be interrupted if it is 35% or more. It is.

  By mixing sawdust and fallen leaves with the rice husk, it is possible to adjust the moisture content of the whole charcoal material. In this case, it is desirable to evenly distribute sawdust and fallen leaves. This is because, if the moisture charcoal material has a large amount of moisture irregularity or component irregularity, the sushi grilling time becomes longer or the sushi grilled irregularity occurs.

  In addition to the rice husk, for example, a cut rice cake can be adopted as the charcoal material. In this case, in order to ensure the flowability of the combustion air, it is desirable to use a cutting rod cut into 3 cm or less. Further, it is also possible to adjust the moisture content by mixing sawdust and the like into the cut rice cake, similarly to the rice husk.

  After the filling of the charcoal material, the screws of both support shafts of the charcoal kiln support mechanism 200 are tightened so that the cylindrical central axis of the charcoal kiln body 110 is vertical, and the charcoal kiln main body 110 is fixed to the charcoal kiln support mechanism 200. To do.

[Placement procedure of canopy 300]
Next, the operator places the canopy 300 on the top peripheral edge of the charcoal kiln body 110. Then, the operation claw of the hook 140c is hung on the peripheral end of the canopy 300, and the operation claw of the hook 140c is operated to be lowered from the unlock position to the lock position. Note that the hooks 140a, 140b, and 140d are left in the release positions (see FIG. 2B).

  At the same time, the operator opens and fixes the lid of the air introduction unit 130 so that air can flow into the air introduction chamber of the charcoal kiln body 110. For example, a support member having a combustible member at the tip is arranged like a stick, and the support member supports the lid of the air introduction unit 130 (see FIG. 2B).

  Further, the worker inserts the chimney connection part 420 of the chimney 400 into the chimney fitting part 310, supports the chimney body 410 by the chimney column 500, and places the chimney 400 in an inclined manner. Then, the wood vinegar container 600 is suspended and arranged at the bottom of the chimney main body 410.

  Next, the operator turns the rotation angle in a top view in order to form a gap S1 that serves as an inlet for the seed fire and serves as an air supply port for allowing the fire to burn and spread over the entire uppermost layer of the charcoal material. The peripheral end portion of the canopy 300 at about 0 ° is slightly lifted, and the protruding portion 720 of the auxiliary instrument 700 is sandwiched between the peripheral end portion of the canopy 300 and the top side peripheral portion of the charcoal kiln main body 110. As a result, a substantially annular gap S <b> 1 can be formed between the canopy 300 and the charcoal kiln body 110. At this time, only the peripheral end portion of the canopy 300 having a rotation angle of about 180 ° abuts on the top side peripheral edge of the charcoal kiln body 110 in the top view, and the disk surface of the canopy 300 is held slightly inclined from the horizontal direction. (Refer to FIG. 2 (b)).

  The maximum width of the substantially annular gap S1 is substantially equal to the vertical maximum separation distance between the canopy 300 and the charcoal kiln body 110, and is sandwiched between the canopy 300 and the charcoal kiln main body 110 of the protrusion 720 of the auxiliary instrument 700. The thickness of the part is almost the same. For example, when the inner diameter of the charcoal kiln main body 110 is 59 cm to 79 cm, the maximum width of the gap S1 is 3 cm to 5 cm.

[Ignition procedure of wood charcoal]
Next, an operator throws in a seed flame from the substantially ring-shaped gap S1 to ignite the uppermost layer of accumulated charcoal material. Then, in the top layer of firewood charcoal material, the part where the seed fire is thrown in first flames up. And this flaming site gradually spreads while being supplied with fresh air.

  In the charcoal manufacturing apparatus of the first embodiment, since the substantially annular gap S1 serving as an air supply port is formed over substantially the entire circumference of the uppermost layer of the charcoal material, the uppermost layer of the charcoal material The fresh air can be supplied evenly over the entire surface, and the air pressure over the wood charcoal material can be evenly and uniformly generated to suppress the generation of airflow. As a result, the supply of fresh air from the igniter and the uneven supply of air, or the air flow generated between the chimney and the igniter causes the fire to extinguish, or unburned parts remain in the charcoal material. That is, the problem that occurred during ignition in the conventional charcoal production apparatus can be solved, and the entire uppermost layer of the charcoal material can be surely burned and completely ignited.

  Furthermore, the substantially ring-shaped gap S1 also serves as an ignition monitoring window, and the operator can visually check the ignition in the charcoal kiln body 110 from various directions, so that the entire uppermost layer of the charcoal material is ignited. It can be easily confirmed that there has been no misunderstanding.

[Closing procedure of gap S1]
Next, when the operator confirms that the flame spreads over the entire uppermost layer of the charcoal material and the entire uppermost layer starts to burn, that is, confirms that the uppermost layer has completely ignited, the canopy 300 and the main body of the charcoal kiln The auxiliary instrument 700 sandwiched between 110 is pulled away from the cylindrical central axis of the charcoal kiln main body 110, and the auxiliary instrument 700 is pulled out (see FIG. 2C).

  Since the protrusion 720 of the auxiliary instrument 700 is provided with a taper portion 725, as the auxiliary instrument 700 is pulled out, the canopy 300 is lowered by its own weight, and the width of the gap S1 is gradually reduced. The peripheral end portion that has been lifted gradually approaches the top peripheral edge of the charcoal kiln body 110 without being accelerated.

  Then, when the auxiliary instrument 700 is completely pulled out, the entire peripheral end of the canopy 300 finally comes into contact with the top peripheral edge of the charcoal kiln main body 110, the gap S1 is eliminated, and the top opening of the charcoal kiln main body 110 is closed. Made. Further, the operator hangs the operating claws of the hooks 140a, 140b, and 140d on the peripheral end portion of the canopy 300, and operates to lower the operation claws of the hooks 140a, 140b, and 140d from the unlocked position to the locked position. Is fixed to the charcoal kiln body 110 (see FIG. 2C).

  In the charcoal manufacturing apparatus according to the first embodiment, the projection 720 of the auxiliary instrument 700 is provided with the tapered portion 725, thereby closing the top opening of the charcoal kiln main body 110 without impacting the canopy 300. Therefore, no impact is applied to the chimney 400 inserted into the chimney fitting portion 310 of the canopy 300, so that the chimney 400 is detached from the canopy 300 or the chimney strut 500 by closing the top opening. The chimney 400 can be stably placed without falling over or tilting the chimney main body 410.

[Procedure for roasting charcoal]
Even if the top opening of the firewood main body 110 is closed by the canopy 300, for the time being, while the oxygen in the air intervening between the canopy 300 and the uppermost layer of the firewood material is consumed, The upper layer continues to burn with flame. When this oxygen is consumed, the flame disappears, and the combustion with the flame shifts to sushi roasting. While burning with flame, black smoke is discharged from the chimney, but after 5 minutes to 10 minutes from the closing, the color of the smoke changes from black to white and the flame disappears. Tsubaki-yaki is started.

  When grilling is started, the grilled layer moves from the upper layer to the lower layer of the charcoal material in search of oxygen in the air. Fresh air containing oxygen flows into the air introduction chamber of the charcoal kiln body 110 from the air introduction unit 130, passes through the lower charcoal material that has not yet been baked, and lowers the bottom of the baked potato layer. To be supplied. Then, the lower layer movement of the sushi roasted layer is performed by the interaction between the heat at the bottom of the sushi baked layer and the oxygen-containing air supplied to the lower sill.

  In this way, sushi roasting is continued while moving from the upper layer to the lower layer of the charcoal material, and reaches the lowermost layer of the charcoal material without interruption, so that all of the charcoal material is baked without leaving any residue. Quality charcoal can be obtained.

  In the charcoal material layer that has been charred after completion of the sushi roasting, the sushi roasting does not proceed any further and the ashing of the charred layer does not occur. This is because the soot generated in the firewood layer passes through the upper soot carbonization layer and is introduced into the chimney, which prevents the soot from ashing.

  Moisture in the charcoal material heated by the sushi roasting is mixed with the smoke and rises and passes through the chimney 400. Since the chimney 400 is inclined and configured to effectively cool the smoke, the smoke is cooled and condensed on the inner surface of the chimney 400 and dropped as a wood vinegar liquid. Can be stored. From the wood vinegar solution stored in the wood vinegar container 600, wood vinegar components and tar components are separated and extracted as necessary.

[Fire extinguishing procedure for charcoal]
When the glazed layer reaches the lowermost layer of the charcoal material, the air supply unit 130 is closed to shut off the supply of air. For example, if the support member that supports the lid of the air introduction part 130 has a combustible member at its tip, the combustible member is burned and burned by the support member when the sashimi layer reaches the lowest layer of the charcoal material. The lid is not supported, and the air introduction unit 130 can be automatically closed (see FIG. 2D).

  At the same time, the operator removes the chimney 400 from the chimney fitting portion 310 of the canopy 300, inserts the protruding portion 720 of the auxiliary device 700 into the chimney fitting portion 310, and places the auxiliary device 700 on the chimney fitting portion 310. And the chimney fitting part 310 is closed by the collar part 710 of the auxiliary instrument 700 (see FIG. 2D). Thereby, the charcoal kiln body 110 can be operated like extinguishing, and the charcoal can be extinguished by leaving it for about 8 hours as it is.

  If all the charcoal is fired and fired, then the fire charcoal during firefighting will not ash if it can be cut off from the air. However, if air is supplied to the charcoal that is being extinguished, the charcoal may be ashed. Therefore, not only shortening the fire extinguishing time but also effectively preventing ashing, when the roasting of the charcoal material is completed, the air introduction part 130 is shielded and the chimney fitting part 310 of the canopy 300 is also shielded. It is desirable to do.

  In the charcoal manufacturing apparatus according to the first embodiment, the chimney fitting part 310 is closed by the auxiliary tool 700, and not only the air introduction part 130 but also the air inflow from the chimney fitting part 310 of the canopy 300 is shielded. By doing so, the time required for fire extinguishing can be shortened and the ashing of the charcoal can be effectively prevented.

  FIG. 4 is a side view illustrating the configuration of another auxiliary instrument in the charcoal manufacturing apparatus according to Embodiment 1 of the present invention. In FIG. 4, the same components as those in FIG. In the auxiliary device 700 of FIG. 3, the taper portion 725 is provided from the base of the projection portion 720 to the protruding end, but the auxiliary device is provided with the taper portion 726 from the middle of the protrusion portion 721 to the protruding end as shown in FIG. It is also possible to adopt 701. Similarly, as shown in FIG. 4B, it is possible to employ an auxiliary instrument 702 in which a tapered portion 727 is provided on the half surface of the protruding portion 722. Furthermore, as shown in FIG. 4C, it is possible to employ an auxiliary instrument 703 in which the tapered portion 728 is curved in the longitudinal direction of the protruding portion 723. In addition, as shown in FIG. 4D, it is also possible to adopt an auxiliary instrument 704 provided on the half surface of the protruding portion 724 with the tapered portion 729 having a concave shape in the longitudinal direction of the protruding portion 724.

  As described above, according to the first embodiment of the present invention, when the firewood material is ignited, the auxiliary appliance 700 is sandwiched between the top peripheral edge of the firewood main body 110 and the canopy 300 to A substantially ring-shaped gap S1 is formed between the canopies 300, and a fire is dropped from the substantially ring-shaped gap S1 to ignite the charcoal material, and the complete ignition of the charcoal material is visually confirmed from the gap S1. After that, the auxiliary tool 700 is pulled out from between the charcoal kiln main body 110 and the canopy 300 to gradually narrow and close the gap S1, and the top opening of the charcoal kiln 100 is closed, so that the uppermost layer of the charcoal material. The entire surface can be reliably ignited.

Embodiment 2
FIG. 5 is a diagram for explaining a partial configuration around the charcoal kiln in the charcoal producing apparatus according to Embodiment 2 of the present invention, where (a) is a top (top) view of the charcoal kiln, and (b) is a charcoal. A side view when the material is ignited, (c) is a side view when the charcoal material is baked. In FIG. 5, the same components as those in FIG.

  The charcoal manufacturing apparatus according to the second embodiment of the present invention includes the charcoal kiln 101, the charcoal kiln support mechanism 200, the canopy 300, the chimney 400, the chimney strut 500, and the wood vinegar container 600. That is, the overall configuration of the charcoal manufacturing apparatus according to the second embodiment of the present invention is such that the charcoal kiln 100 in FIG. The charcoal manufacturing apparatus according to Embodiment 2 sequentially fires and burns the charcoal material filled in the charcoal kiln 101 from the top side to the bottom side to produce charcoal, and also uses a wood vinegar liquid (crude wood vinegar). Liquid).

[Scoal kiln 101]
The charcoal kiln 101 includes a charcoal kiln main body 110, a grid plate 120 (see FIG. 2), an air introduction unit 130, a plurality of hooks 140 (140a, 140b, 140c, 140d), and a plurality of support units 150 (150a, 150b, 150c, 150d) and a plurality of elastic bodies 160 (160a, 160b, 160c, 160d). That is, the charcoal kiln 101 of the second embodiment is provided with the support 150 and the elastic body 160 in the charcoal kiln 100 of the first embodiment.

  The charcoal kiln main body 110 is a substantially cylindrical kiln having an open top (upper side), and is made of, for example, stainless steel or iron. A grid plate 120 is stretched inside the charcoal kiln body 110. The grid plate 120 divides the inside of the charcoal kiln body 110 into a bottom (lower) air introduction chamber and a top steaming chamber.

  A substantially square tube-shaped air introduction portion 130 that leads to the air introduction chamber is provided on a side surface portion near the bottom surface of the charcoal kiln main body 110. The air introduction part 130 can be opened and closed by a lid provided at the protruding end. In addition, unlike the conventional charcoal manufacturing apparatus, the charcoal manufacturing apparatus according to the second embodiment does not require an ignition port on the side surface of the charcoal kiln body 110.

  A hook 140 (140a, 140b, 140c, 140d) is provided on the outer side surface portion in the vicinity of the top peripheral edge portion of the charcoal kiln body 110. Moreover, the support body 150 (150a, 150b, 150c, 150d) is fixedly provided on the inner side surface portion in the vicinity of the top side peripheral edge portion of the charcoal kiln main body 110. Furthermore, on these supports 150, elastic bodies 160 (160a, 160b, 160c, 160d) are respectively fixed so that one end is fixed to the support 150 and the other end is located on the top side of the one end. Is arranged. In addition to the coil spring, a plate spring, a shock absorber, or the like can be used as the elastic body 160.

  When the rotation angle of the part of the air introduction part 130 is 0 ° on the circumference in the top view (top view), the hook 140a, the support 150a, and the elastic body 160a supported by the hook 140a are the same rotation angle as the air introduction part 130. At the position of 0 °, the hook 140b and the support 150b and the elastic body 160b supported by the hook 140b are positioned at a rotation angle of 90 °, and the hook 140c, the support 150c and the elastic body 160c supported by the hook 140b are supported by the rotation angle of 180 °. In this position, the hook 140d, the support 150d and the elastic body 160d supported by the hook 140d are provided at a rotation angle of 270 °, respectively. That is, each of the hook 140, the support 150, and the elastic body 160 supported by the hook 140 is arranged four by four so that the center angle between them is 90 ° when viewed from above.

  Note that, for example, the hooks, the support bodies, and the elastic bodies supported by the hooks and the elastic bodies supported by the hooks and the support bodies and the elastic bodies supported by the hooks are arranged at 120 °, and the center angles between the hooks and the support bodies are 60 °. In addition, it is possible to arrange six hooks, support members, and elastic members supported by the hooks.

  The support 150, the elastic body 160 supported by the support 150, and the hook 140 constitute the ignition assisting means according to the second embodiment of the present invention. The ignition assisting means of the present invention, when igniting the charcoal material filled in the charcoal kiln 100 from the top side, throws the fire type between the charcoal kiln 101 and the canopy 300 by shifting the canopy 300 to the top side. After forming a substantially ring-shaped gap for igniting the firewood material, the position of the shifted canopy 300 is returned to the original position to eliminate the gap and close the top opening of the firewood kiln 101. It is to be made.

  When the support body 150 and the elastic body 160 and the hook 140 supported by the support body 150 are ignited by the charcoal material, the peripheral end portion of the canopy 300 placed on the other end of the elastic body 160 is the elastic body 160. Is pressed to the other end of the frame to create a substantially ring-shaped gap S2, and after the fire charcoal material is ignited, the elastic body 160 is contracted as the hook 140 is operated to the locked position, thereby forming the gap S2. It gradually narrows and closes.

  The hook 140 is operated to the release position by the operator, for example, when the top cover 300 is removed and the top opening of the charcoal kiln body 110 is released. In this release position, even if the canopy 300 is placed on the other end of the elastic body 160, the operating claw of the hook 140 is at a position away from the peripheral end of the canopy 300. Therefore, the canopy 300 is not restrained at all by the hook 140, but is only pressed to the top side by the elastic body 160, and does not come into contact with the top side peripheral portion of the charcoal kiln body 110, and the force and elasticity by its own weight. It stops at a position where the pressing force of the body 160 is balanced.

  Here, even if the operator hooks the operating claw on the peripheral end portion of the placed canopy 300 and the hook 140 is operated from the release position to the unlocking position, the canopy 300 is not in contact with the charcoal kiln body 110. The elastic body 160 is placed on the other end while the substantially annular gap S2 is held.

  When the operator operates the operation claw of the hook 140 from the unlocked position to the locked position, the operating claw of the hook 140 urges the peripheral end of the canopy 300 downward (toward the charcoal kiln main body 110 side). As a result, the elastic body 160 is contracted, whereby the width of the substantially annular gap S2 is gradually narrowed. Finally, the gap S2 disappears, and the entire peripheral edge of the canopy 300 is connected to the top peripheral edge of the charcoal kiln main body 110. The canopy 300 is fixed on the charcoal kiln body 110.

[Steaming charcoal kiln support mechanism 200]
The charcoal kiln support mechanism 200 supports the charcoal kiln 101 in a hollow position by two support shafts. These two support shafts are provided at substantially the center position of the side surface in the cylindrical axis direction of the charcoal kiln main body 110. Further, these two support shafts are provided at a position where the center angle between them is 180 ° when viewed from above. Each support shaft is provided at a position where the central angle formed with the air introduction part 130 is 90 ° in a top view.

[Canopy 300]
The canopy 300 is a substantially disk-shaped lid that is detachably mounted on the top peripheral edge of the charcoal kiln main body 110 and closes the top opening of the charcoal kiln main body 110. A substantially cylindrical chimney fitting portion 310 is provided near the peripheral end portion of the canopy 300 and at a position shifted from the center of the canopy 300 in a top view. The chimney 400 is detachably connected to the canopy 300 by inserting the chimney 400 into the inner peripheral side surface of the chimney fitting portion 310. It is also possible to adopt a configuration in which the inner peripheral side surface of the chimney 400 is inserted into the chimney fitting portion 310.

  The canopy 300 is placed on the charcoal kiln main body 110 so that the chimney fitting portion 310 is positioned at a rotation angle of about 180 ° on the circumference as viewed from above. Therefore, when viewed from above, the central angle formed by the chimney fitting part 310 of the canopy 300 and the air introduction part 130 of the charcoal kiln body 110 is about 180 °.

[Chimney 400]
The chimney 400 includes a chimney main body 410 and a chimney connection part 420. The chimney body 410 has a substantially long cylinder. The chimney connection portion 420 has an L-shaped substantially cylindrical shape. The chimney main body 410 is connected to one end of the chimney connection portion 420 at a side surface near the bottom thereof. The other end of the chimney connection portion 420 is removably inserted into the chimney fitting portion 310 of the canopy 300. The chimney 400 discharges the soot generated in the charcoal kiln 101 by sushi-burning of the charcoal material, and cools the soot efficiently inside, thereby generating dew condensation of the pyroligneous acid liquid.

  The chimney main body 410 can be rotated around the chimney connection part 420 at the connection site with the chimney connection part 420. The chimney main body 410 is disposed so as to be inclined so that the longitudinal direction forms an obtuse angle with the vertical direction (makes an acute angle with the installation surface of the charcoal manufacturing apparatus).

[Chimney strut 500]
The chimney strut 500 is installed between the top side of the chimney main body in the longitudinal direction and the installation surface of the charcoal manufacturing apparatus, and supports the chimney main body 410 that is inclined. Note that one or a plurality of cooling holes are provided at a substantially intermediate position in the longitudinal direction of the chimney main body 410.

[Wood vinegar container 600]
The wood vinegar container 600 is suspended from the bottom of the chimney main body 410. The bottom of the chimney main body 410 is provided with a pyroligneous liquid drop hole, and the pyroligneous acid container 600 is provided so as to be located directly below the pyrogenic acid liquid drop hole. The wood vinegar liquid that is highly condensed on the inner surface of the chimney body 410 by the inclined arrangement of the chimney body 410 and the cooling holes provided in the chimney body 410 is dropped from the vinegar droplet lower hole and stored in the wood vinegar container 600. It is done.

  The procedure for producing the charcoal and the pyroligneous acid liquid using the apparatus for producing charcoal of the second embodiment will be described below.

[Procedure for filling charcoal material]
First, the operator removes the canopy 300 from the charcoal kiln body 110. Then, the charcoal material is accumulated and filled in the fired roasting chamber of the charcoal kiln main body 110 so as to be pushed in from above. At this time, the screws of both support shafts of the charcoal kiln support mechanism 200 are loosened so that the charcoal kiln main body 110 can swing with both support shafts used as swing shafts. That is, the cylindrical central axis of the substantially cylindrical charcoal kiln body 110 can be inclined with respect to the vertical direction. The operator tilts the charcoal kiln body 110 so that the charcoal material can be easily put, and fills the charcoal kiln body 110 with the charcoal kiln body 110.

  For example, rice husk is used as the charcoal material. The moisture content of the entire firewood charcoal material is preferably 10% (weight%) to 35%, for example, and the optimum value is 20% to 25%. As described above, the moisture content of the entire charcoal material is 10% to 35% because the recovery of the pyroligneous liquor may be reduced if it is 10% or less, and the roasting may be interrupted if it is 35% or more. It is.

  By mixing sawdust and fallen leaves with the rice husk, it is possible to adjust the moisture content of the whole charcoal material. In this case, it is desirable to evenly distribute sawdust and fallen leaves. This is because, if the moisture charcoal material has a large amount of moisture irregularity or component irregularity, the sushi grilling time becomes longer or the sushi grilled irregularity occurs.

  In addition to the rice husk, for example, a cut rice cake can be adopted as the charcoal material. In this case, in order to ensure the flowability of the combustion air, it is desirable to use a cutting rod cut into 3 cm or less. Further, it is also possible to adjust the moisture content by mixing sawdust and the like into the cut rice cake, similarly to the rice husk.

  After the filling of the charcoal material, the screws of both support shafts of the charcoal kiln support mechanism 200 are tightened so that the cylindrical central axis of the charcoal kiln body 110 is vertical, and the charcoal kiln main body 110 is fixed to the charcoal kiln support mechanism 200. To do.

[Placement procedure of canopy 300]
Next, the operator attaches the canopy 300 to the charcoal kiln in order to form a gap S2 that serves as an inlet for the seed fire and serves as an air supply port for allowing the fire to spread over the entire uppermost layer of the charcoal material. 100 is placed on the other end of the elastic body 160 (160a, 160b, 160c, 160d), and the action claws of the hook 140 (140a, 140b, 140c, 140d) are respectively attached to the peripheral end of the canopy 300. All these hooks 140 are operated to the unlocked position. Thereby, a substantially annular gap S <b> 2 can be formed between the canopy 300 and the charcoal kiln body 110. At this time, the disk surface of the canopy 300 is held substantially horizontally, and the width of the substantially ring-shaped gap S2 is substantially the same over the entire 360 ° range as viewed from above (see FIG. 5B).

  The width of the substantially annular gap S <b> 2 is substantially equal to the vertical separation distance between the canopy 300 and the charcoal kiln body 110. For example, when the inner diameter of the charcoal kiln main body 110 is 59 cm to 79 cm, the maximum width of the gap S2 is 3 cm to 5 cm.

  At the same time, the operator opens and fixes the lid of the air introduction unit 130 so that air can flow into the air introduction chamber of the charcoal kiln body 110. For example, a support member having a combustible member at the tip is arranged like a stick and the support member supports the lid of the air introduction unit 130.

  Further, the worker inserts the chimney connection part 420 of the chimney 400 into the chimney fitting part 310, supports the chimney body 410 by the chimney column 500, and places the chimney 400 in an inclined manner. Then, the wood vinegar container 600 is suspended and arranged at the bottom of the chimney main body 410.

[Ignition procedure of wood charcoal]
Next, the operator throws in a seed fire from the annular gap S2 to ignite the uppermost layer of the accumulated fuel charcoal. Then, in the top layer of firewood charcoal material, the part where the seed fire is thrown in first flames up. And this flaming site gradually spreads while being supplied with fresh air.

  In the charcoal producing apparatus according to the second embodiment, since the substantially annular gap S2 serving as an air supply port is formed over the entire circumference of the uppermost layer of the charcoal material, the entire uppermost layer of the charcoal material is formed. The fresh air can be supplied uniformly, and the air pressure over the wood charcoal material can be evenly distributed to suppress the generation of airflow. As a result, the supply of fresh air from the igniter and the uneven supply of air, or the air flow generated between the chimney and the igniter causes the fire to extinguish, or unburned parts remain in the charcoal material. That is, the problem that occurred during ignition in the conventional charcoal production apparatus can be solved, and the entire uppermost layer of the charcoal material can be surely burned and completely ignited.

  Furthermore, the substantially annular gap S2 also serves as an ignition monitoring window, and the operator can visually check the ignition in the charcoal kiln body 110 from various directions, so that the entire uppermost layer of the charcoal material is ignited. It can be easily confirmed that there has been no misunderstanding.

[Closing procedure of gap S2]
Next, when the operator confirms that the flame has spread over the entire uppermost layer of the charcoal material and that the entire uppermost layer has started to burn, that is, confirms that the uppermost layer has completely ignited, By operating, all the hooks 140 are moved from the unlocked position to the locked position (see FIG. 5C).

  Since the canopy 300 is pressed to the top side by the elastic body 160, as the hook 140 is operated from the unlocked position to the locked position, the canopy 300 descends as the elastic body 160 contracts, and the width of the gap S2 increases. It gradually narrows, and the peripheral end of the canopy 300 gradually approaches the top peripheral edge of the charcoal kiln body 110 without being accelerated.

  Then, when the hook 140 is completely in the locked position, the entire peripheral end portion of the canopy 300 finally comes into contact with the top side peripheral portion of the charcoal kiln main body 110, the gap S2 is eliminated, and the top opening of the charcoal kiln main body 110 is closed. The canopy 300 is fixed to the charcoal kiln body 110 (see FIG. 5C).

  In the charcoal producing apparatus of the second embodiment, the top of the charcoal kiln main body 110 is not affected by the support 150 provided in the charcoal kiln main body 110, the elastic body 160 supported by the support 150, and the hook 140 without impacting the canopy 300. Since the side opening can be closed, and therefore, the chimney 400 inserted into the chimney fitting part 310 of the canopy 300 is not impacted, the chimney 400 is separated from the canopy 300 by closing the top opening. The arrangement of the chimney 400 can be stably maintained without being detached, the chimney column 500 falling over, or the chimney body 410 being inclined.

[Procedure for roasting charcoal]
Even if the top opening of the firewood main body 110 is closed by the canopy 300, for the time being, while the oxygen in the air intervening between the canopy 300 and the uppermost layer of the firewood material is consumed, The upper layer continues to burn with flame. When this oxygen is consumed, the flame disappears, and the combustion with the flame shifts to sushi roasting. While burning with flame, black smoke is discharged from the chimney, but after 5 minutes to 10 minutes from the closing, the color of the smoke changes from black to white and the flame disappears. Tsubaki-yaki is started.

  When grilling is started, the grilled layer moves from the upper layer to the lower layer of the charcoal material in search of oxygen in the air. Fresh air containing oxygen flows into the air introduction chamber of the charcoal kiln body 110 from the air introduction unit 130, passes through the lower charcoal material that has not yet been baked, and lowers the bottom of the baked potato layer. To be supplied. Then, the lower layer movement of the sushi roasted layer is performed by the interaction between the heat at the bottom of the sushi baked layer and the oxygen-containing air supplied to the lower sill.

  In this way, sushi roasting is continued while moving from the upper layer to the lower layer of the charcoal material, and reaches the lowermost layer of the charcoal material without interruption, so that all of the charcoal material is baked without leaving any residue. Quality charcoal can be obtained.

  In the charcoal material layer that has been charred after completion of the sushi roasting, the sushi roasting does not proceed any further and the ashing of the charred layer does not occur. This is because the soot generated in the firewood layer passes through the upper soot carbonization layer and is introduced into the chimney, which prevents the soot from ashing.

  Moisture in the charcoal material heated by the sushi roasting is mixed with the smoke and rises and passes through the chimney 400. Since the chimney 400 is inclined and configured to effectively cool the smoke, the smoke is cooled and condensed on the inner surface of the chimney 400 and dropped as a wood vinegar liquid. Can be stored. From the wood vinegar solution stored in the wood vinegar container 600, wood vinegar components and tar components are separated and extracted as necessary.

[Fire extinguishing procedure for charcoal]
When the glazed layer reaches the lowermost layer of the charcoal material, the air supply unit 130 is closed to shut off the supply of air. For example, if the support member that supports the lid of the air introduction part 130 has a combustible member at its tip, the combustible member is burned and burned by the support member when the sashimi layer reaches the lowest layer of the charcoal material. The lid is not supported, and the air introduction unit 130 can be automatically closed.

  Along with this, the auxiliary instrument 700 (see FIGS. 2 and 3) of the first embodiment is adopted, the chimney 400 is removed from the chimney fitting part 310 of the canopy 300, and the auxiliary instrument 700 is placed in the chimney fitting part 310. It is also possible to insert the protruding portion 720, place the auxiliary instrument 700 on the chimney fitting part 310, and close the chimney fitting part 310 by the collar part 710 of the auxiliary instrument 700. Thereby, the charcoal kiln main body 110 can be operated like extinguishing, and the charcoal can be extinguished in a short time by leaving it as it is.

  If all the charcoal is fired and fired, then the fire charcoal during firefighting will not ash if it can be cut off from the air. However, if air is supplied to the charcoal that is being extinguished, the charcoal may be ashed. Therefore, not only shortening the fire extinguishing time but also effectively preventing ashing, when the roasting of the charcoal material is completed, the air introduction part 130 is shielded and the chimney fitting part 310 of the canopy 300 is also shielded. It is desirable to do.

  The auxiliary instrument 700 of the first embodiment is adopted, and the chimney fitting part 310 is closed by the auxiliary instrument 700 so that not only the air introduction part 130 but also the air inflow from the chimney fitting part 310 of the canopy 300 is prevented. Shielding can also reduce the time required for extinguishing the fire and effectively prevent the ashing of the charcoal.

  As described above, according to the second embodiment of the present invention, when the charcoal material is ignited, the canopy 300 is pressed between the other ends of the elastic body 160 to press the canopy 300 between the charcoal kiln 101 and the canopy 300. A mold gap S2 is formed, a seed fire is dropped from this substantially annular gap S2, the firewood charcoal material is ignited, and the complete ignition of the firewood charcoal material is visually confirmed from the gap S2, and then the hook 140 is locked. By operating to the position, the gap S2 is gradually narrowed and closed, and the top opening of the charcoal kiln 100 is closed, so that the entire uppermost layer of the charcoal material is reliably ignited as in the first embodiment. be able to.
