Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a drying process system for beer lees, and more particularly to a beer lees drying process system in which a drying process in a pre-carbonization process using beer lees is devised.
[0002]
[Prior art]
  In general, a large amount of beer lees is produced in the beer manufacturing process. As a method for using beer lees produced in such a beer manufacturing process, various techniques such as lees cultivation, protein utilization, soil improvement, etc. have been proposed in addition to livestock feed. Recently, attempts have been made to carbonize beer lees to obtain solid fuel.
[0003]
  As the carbonization method of this beer lees, the carbonization method disclosed in Japanese Patent Laid-Open No. 2-294391 (Prior Example 1) and the method disclosed in Japanese Patent Laid-Open No. 08-9954 (Previous Example 2) are disclosed. Such a dehydration carbonization method is known.
[0004]
[Problems to be solved by the invention]
  However, in the preceding example 1 and the preceding example 2, the moisture content of the beer lees dried through the drying step in the pre-carbonization step is high, and in any case, in the carbonization method of the beer lees, in the molding step, High-pressure fuel charcoal cannot be obtained because high-pressure molding of a solid body (molded product) of beer lees cannot be performed.
[0005]
  By the way, the beer lees produced in the process of producing beer are usually made from beer lees that have been mechanically lowered to a moisture content of about 65% and further dried to about 10% for livestock feed. In order to produce high quality fuel charcoal, it is necessary to dry the water content of the beer lees to about 1 to 6% due to the necessity of high pressure molding of the solid body of the beer lees. When the water content is 6% or more, high-pressure molding of the solid body of beer lees becomes difficult.
[0006]
  Moreover, when carbonizing such a solid body (molded product) of beer lees, it is necessary to obtain fuel charcoal after carbonization with a form with few bends as much as possible, and the fuel char bend is large. In addition, the packaging work is troublesome, and not only the volume is bulky, but also the yield is poor because it is easy to break.
[0007]
  The present invention has been made in view of the above circumstances, and makes it possible to dry a wet beer lees with a moisture content of 65% generated in the beer manufacturing process to a moisture content of about 1 to 6%, and by high pressure molding. It is an object of the present invention to provide a beer koji drying processing system which can be easily formed into a desired solid form.

[0010]
DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 and FIG. 2 schematically show the overall configuration of the beer lees drying and carbonization processing system according to the present invention, and reference numeral 100 indicates drying. A processing system 200 is a carbonization processing system.
[0011]
  As shown in FIGS. 3 and 4, the drying processing system 100 has a hopper (beer lees supply container) 1 into which wet beer lees P1 generated in a beer manufacturing process (not shown) is charged. The wet beer lees P1 charged into the hopper 1 is cut out and discharged to a predetermined supply amount by a cutting and discharging machine 2 composed of a multiple screw installed at the lower part of the discharge port side. .
[0012]
  The cutting and unloading machine 2 adjusts the number of rotations of each screw manually or automatically so that the cutting amount of the wet beer bottle P1 can be adjusted. The straw P1 is transported toward the flight conveyor 3 and is dried in the flight conveyor 3 in the primary drying furnace 10 to be described later and the secondary drying furnace 20 provided in parallel with the primary drying furnace 10. It is supposed to be.
[0013]
  As shown in FIG. 5, the primary drying furnace 10 is provided with a supply port 11 </ b> A at the top of the furnace 11, and the wet beer lees P <b> 1 conveyed by the flight conveyor 3 from the supply port 11 </ b> A It is supplied and supplied toward the perforated plate 12 arranged in the middle part. On the perforated plate 12, a stirring blade 13 is provided. By rotating the stirring blade 13 with a drive motor 13A, the agglomerated wet beer cake P1 is divided into pieces, and the inside of the furnace When the hot air H blown from the bottom of 11 through the first hot air blowing means is blown through the perforated plate 12, the primary drying of the wet beer cake P <b> 1 is performed.
[0014]
  The first hot air blowing means includes a combustion burner 14 installed outside the primary drying furnace 10, a burner fan 15 for supplying combustion air to the combustion burner 14, and a combustion burner together with combustion air from the burner fan 15. 14 has a dilution fan 16 that dilutes the combustion exhaust gas burned in 14 to an appropriate hot air H, and an adjustment valve 17 that can automatically or manually adjust the amount of hot air H diluted by the dilution fan 16.
[0015]
  That is, the combustion burner 14 constituting the first hot air blowing means burns liquid fuel such as kerosene supplied from the fuel tank 4 such as a kerosene tank together with the combustion air by the burner fan 15 and the combustion exhaust gas thereof. Is diluted to an appropriate hot air H by a dilution fan 16 and blown into the furnace 11 so as to blow the wet beer cake P1 that has been agglomerated by the stirring blade 13 while performing constant rate drying by continuous fluidized drying, ie, preliminary Drying is performed.
[0016]
  A discharge port 11B communicating with the supply port 21A opening in the furnace 21 of the secondary drying furnace 20 through the transport path 5 is opened on the bottom side of the furnace 11 of the primary drying furnace 10, and this discharge port 11B The first overflow adjusting plate 18 is provided so that the height can be adjusted. The overflow adjusting plate 18 is adjusted in height according to the processing amount and the degree of drying of the semi-dried beer lees P2 that has been primarily dried in the furnace 11 of the primary drying furnace 10. As a result, the amount of inflow of the semi-dried beer leash P2 that passes over the overflow adjusting plate 18 and flows into the secondary drying furnace 20 can be adjusted.
[0017]
  In the furnace 21 of the secondary drying furnace 20, the semi-dried beer cake P2 that has been primarily dried in the primary drying furnace 10 is supplied through the supply port 21A toward the perforated plate 22 disposed in the middle portion thereof. It has come to be. On the perforated plate 22, a stirring blade 23 is provided. By rotating the stirring blade 23 with a drive motor 23 </ b> A, the quasi-dried beer cake P <b> 2 to be agglomerated is separated from the bottom of the furnace 21. By blowing hot air H blown through the second hot air blowing means through the perforated plate 22, secondary drying of the semi-dried beer cake P2, that is, main drying is performed.
[0018]
  The second hot air blowing means is combusted together with a combustion burner 24 installed outside the secondary drying furnace 20, a burner fan 25 for supplying combustion air to the combustion burner 24, and combustion air by the burner fan 25. A dilution fan 26 for diluting the combustion exhaust gas combusted by the burner 24 to an appropriate hot air H, and an adjustment valve 27 capable of automatically or manually adjusting the amount of hot air H diluted by the dilution fan 26. Have.
[0019]
  That is, the combustion burner 24 constituting the second hot air blowing means burns liquid fuel such as kerosene supplied from the fuel tank 4 together with combustion air by the burner fan 25, and the combustion exhaust gas is diluted by the dilution fan 26. By diluting with moderate hot air H and blowing it into the furnace 21, reduction drying by continuous fluidized drying is performed while blowing up the semi-dried beer cake P <b> 2 that has been divided by the stirring blade 23. In addition, as a heat source of the first and second hot air blowing means, exhaust gas such as a boiler can be used in addition to the above-described combustion burner.
[0020]
  Further, a static pressure control plate 28 is provided at the supply port 21A in the furnace 21 of the secondary drying furnace 20 so that the opening degree can be adjusted. By adjusting the opening degree of the static pressure control plate 28, the internal pressures in the furnace 11 of the primary drying furnace 10 and the furnace 21 of the secondary drying furnace 20 become unstable due to pulsation, and between them. When a static pressure difference occurs, the hot air from the furnace 11 of the primary drying furnace 10 or the furnace 21 of the secondary drying furnace 20 and the beer cake in the middle of drying flow into the other furnace. Therefore, the fluidized bed of beer lees is prevented from becoming unstable.
[0021]
  That is, the reason why the static pressure control plate 28 is provided is that the internal pressures in the furnaces 11 and 21 of the primary drying furnace 10 and the secondary drying furnace 20 are designed to maintain the same level. When the soot enters a fluidized state, its pressure in the furnace is pulsating and not always constant. As a result, a static pressure difference may occur at a certain timing between the furnaces 11 and 21 of the respective drying furnaces 10 and 20, so if there is no static pressure control plate 28, the hot air H is caused by this static pressure difference. This is because inflow and beer lees also flow along with it.
[0022]
  Moreover, when such a phenomenon occurs, the drying furnace 10 or 20 from which the beer lees have flowed out is blown out in the fluidized bed of the beer lees that have been stable until then, and the unstable state is maintained. The situation becomes impossible to dry. If the static pressure control plate 28 is present as in the present invention, even if a static pressure difference occurs between the drying ovens 10 and 20, there is no gas inflow or beer lees inflow due to the sealing effect of the beer lees themselves. For this reason, the fluidized bed of the beer lees is continuously stabilized. In addition, if the static pressure control plate 28 closes the supply port 21A side of the secondary drying furnace 20, the flow between the respective drying furnaces 10 and 20 can be completely cut off. A stable fluidized bed of beer can be easily obtained in a short time.
[0023]
  Further, a discharge port 21B is opened at the bottom of the inside 21 of the secondary drying furnace 20, and a second overflow adjusting plate 29 is provided at the discharge port 21B so that the height can be adjusted. The overflow adjusting plate 29 is adjusted in height according to the processing amount and the degree of drying of the dried beer lees P3 secondary dried in the furnace 21 of the secondary drying furnace 20. As a result, it is possible to adjust the discharge amount of the dried beer lees P3 that are passed over the overflow adjustment plate 29 and discharged to the discharge path 6, and the outlet of the secondary drying furnace 20 is disposed on the outlet side of the discharge path 6 A damper 7 that discharges the dried beer cake P3 together with the hot air H of the inside 21 toward a molding machine to be described later is provided so as to be openable and closable.
[0024]
  Exhaust ports 11C and 21C connected to the exhaust passage 30 are opened above the interiors 11 and 21 of the primary drying furnace 10 and the secondary drying furnace 20, respectively. The exhaust cylinders 31 and 32 are provided in communication with each other. The exhaust path 30 is formed by connecting the exhaust cylinders 31 and 32 to each other through an exhaust pipe 33, and a cyclone 34 is connected to the exhaust pipe 33. The beer lees P1 and P2 which are captured by the cyclone 34 and dissipated together with the exhaust gas exhausted from the furnaces 11 and 21 of the primary drying furnace 10 and the secondary drying furnace 20 are re-dried. The dried beer cake P3 is put into a molding machine, which will be described later, and molded into a desired solid W form. In addition to the above-described cyclone 34, a bag filter or the like can be used.
[0025]
  By the way, in the continuous fluidized drying method as described above, in order to improve the drying performance in the drying furnace using the fluidized bed of the object to be dried, energy (fluid of the fluid) for fluidizing the object to be dried in the drying furnace is used. The consistency between the kinetic energy and the energy for drying (thermal energy of the fluid) is required. If such consistency is not obtained, even if the operation up to fluidization of the object to be dried is possible, if the thermal energy of the hot air H blown into the drying furnace is insufficient, the object to be dried is intended. It cannot be dried to the moisture content (water content). Further, if it is attempted to compensate for the lack of thermal energy of the hot air H by merely increasing the air volume of the hot air H without changing the temperature, the drying method using the fluidized bed of the object to be dried advances one step, Therefore, an object to be dried such as beer lees will be dissipated from the inside of the drying furnace.
[0026]
  On the other hand, if we try to compensate by increasing the hot air temperature without changing the air volume of the hot air H, the organic matter as the material to be dried, such as beer lees, is affected by heat at 130 ° C. (temperature of the beer lees). As a result, the material changes and the molding is hindered.
[0027]
  The object of the present invention is to dry the wet beer lees P1 having a moisture content of 65% generated in the beer manufacturing process to a moisture content of 1 to 6% in order to enable high pressure molding of the beer lees. However, the wet beer lees P1 having a moisture content of 65% has a large moisture content and is not suitable for fluid drying. In addition, when the moisture content is 10% or less, the drying efficiency tends to be extremely poor. In other words, the operation is a so-called reduction rate drying area.
[0028]
  Under such circumstances, if the fluidized drying of the wet beer lees P1 as described above is carried out with only one drying furnace, the energy for fluidizing the material to be dried in the drying furnace and the drying Finding an energy match is extremely difficult. The present invention finds that the drying performance is achieved by performing the two-stage drying of the wet beer lees P1 in two drying furnaces. In addition, if the drying process is performed in a two-stage manner as described above, the air volume and hot air temperature of the hot air H can be set for each stage, so that a higher degree of freedom can be obtained.
[0029]
  Thus, in the drying treatment system according to the present invention as shown in FIG. 5, the moisture content of the wet beer lees P1 in the charging stage to the primary drying furnace 10 is 65%, and after the wet beer lees P1 is primarily dried The moisture content of the semi-dried beer cake P2 on the discharge port 11B side of the primary drying furnace 10 is dried to about 35 to 40%, and the moisture content of the dried beer cake P3 on the discharge port 21B side of the secondary drying furnace 20 is Finally, it can be dried to a target value of about 1 to 6%.
[0030]
  In particular, in the present invention, the main point is that the moisture content can be dried by 3% by controlling the supply amount of the semi-dried beer leash P2 so that the exhaust temperature of the secondary drying furnace 20 is about 100 ° C. . By setting the exhaust temperature to 90 to 120 ° C., preferably 90 to 110 ° C., dried beer lees P3 having a moisture content of 1 to 6% is obtained.
[0031]
  According to the experiment, the optimum hot air temperature, hot air speed, and hot air mass speed in the primary drying furnace 10 and the secondary drying furnace 20 indicate that the charge amount of beer lees is, for example, 280 kg / h, respectively. Is 200 ° C. and 230 ° C., the hot air velocity is 1.4 m / s and 1.8 m / s, and the mass velocity of the hot air H is 3800 kg / m.²・ H and 4400kg / m²H, the exhaust temperature is 65 ° C. and 120 ° C., respectively, and the product temperature is 60 ° C. and 120 ° C., respectively. In such numerical data, consistency satisfying the drying performance as described above was obtained.
[0032]
  On the other hand, as Comparative Example 1 in the case where only the primary drying furnace 10 is used, the beer koji charge amount is, for example, 140 kg / h, and the hot air speed is 1.8 m / s. In the fluidization of the soot P1, a stable fluidized bed was not formed in the primary drying furnace 10, and it became an air current conveying or pulsating state, which became a state incapable of drying.
[0033]
  Further, as Comparative Example 2 in the case where only the primary drying furnace 10 is used, for example, according to the results of an experiment with a hot air speed of 1.2 to 1.4 m / s and a hot air temperature of 230 to 300 ° C., the moisture content However, the wet beer lees P1 with 65% decreased to a water content of about 10%, but could not be reduced to a water content of 1 to 6%, which is the target value of the present invention.
[0034]
  Similarly, in the continuous fluidized drying method, if the energy (mass and gas speed) for fluidizing the material to be dried in the drying furnace and the energy (mass and temperature) for drying are poor, The fluidized bed of the material to be dried is not formed well, the drying becomes insufficient, or the drying is excessive, that is, energy is wasted.
[0035]
  Also, when monitoring (measuring) the exhaust gas temperature from the drying furnace (hot air temperature after drying) and controlling the temperature at the inlet of the drying furnace, increase or decrease the fuel consumption or increase or decrease the amount of combustion air. When the fuel consumption is increased / decreased as in the former when controlling the temperature, the increase / decrease in temperature results in an indirect increase / decrease in the actual gas amount (gas volume by temperature conversion). On the other hand, if the amount of combustion air is increased or decreased like the latter, the amount of gas directly increases or decreases. This is an operation that shifts the matching point between the fluidization and drying of the material to be dried in the drying furnace, and the moisture content is 65% as in the case of wet beer lees produced in the beer manufacturing process, which is essentially continuous fluidized drying. When drying an unsuitable to-be-dried object, it becomes a factor which makes the fluidized bed of the to-be-dried object in a drying furnace unstable.
[0036]
  Therefore, in the beer lees drying processing system according to the present invention, the hot air temperature and the air flow into the drying oven are always kept constant, and the beer lees drying oven as the object to be dried according to the exhaust temperature from the drying oven. By increasing or decreasing the supply amount to the beer, the matching point between fluidization and drying of the fluidized bed of beer lees in the drying furnace is matched. That is, if the exhaust temperature of the drying furnace is lower than the set value, the supply amount of beer lees is controlled to decrease, and if the exhaust temperature is higher than the set value, the supply amount of beer lees is controlled to increase. Is.
[0037]
  As a specific method, for example, as shown in FIG. 3, a temperature sensor 35 made of, for example, a thermocouple is installed in each exhaust pipe 31, 32 of the primary drying furnace 10 and the secondary drying furnace 20, and this temperature is set. The sensor 35 detects the exhaust temperature of the exhaust gas exhausted from each of the drying furnaces 10 and 20. The exhaust temperatures of these drying furnaces 10 and 20 are sent to the temperature indicating controller 36 as a temperature signal (mV), and this temperature (PV value) is the temperature (SP value) set in the temperature indicating controller 36. Compared with When the exhaust temperature (PV value) at this time is lower than the set temperature (SP value) (PV value <SP value), an instruction signal for the rotational speed is sent from the temperature indicating controller 36 to the inverter 37. This inverter 37 controls the multiple screw type cutting machine 2 that cuts out the wet beer lees P1 from the hopper 1, and controls so that the number of rotations of the drive motor 38 decreases, so that the wet beer to the primary drying furnace 10 is controlled. The exhaust gas temperature is raised by reducing the supply amount of the soot P1.
[0038]
  On the other hand, when the exhaust temperature (PV value) of the drying furnaces 10 and 20 is higher than the set temperature (SP value) (PV value> SP value), the rotational speed of the drive motor 38 of the cutting machine 2 is increased. By controlling and increasing the supply amount of wet beer lees P1 to the primary drying furnace 10, the exhaust temperature is lowered.
[0039]
  As described above, the present invention provides a fluidized bed of beer lees in the drying furnace by constantly keeping the hot air temperature and the air volume in the drying furnace constant and controlling the exhaust temperature of the drying furnace by the supply amount of the beer lees. It is possible to match the matching points of fluidization and drying of the beer, so that the fluidized bed of the beer lees in the drying furnace is stabilized, the beer lees can be dried to a desired degree of drying, and the equipment of the drying oven The capacity can be used up and down. Moreover, since the temperature of the hot air blown into the drying furnace is controlled to be constant, there is no need to perform heating / cooling of the drying furnace, that is, heating / cooling by accumulating heat of the drying furnace, which is also suitable for energy saving measures. It is.
[0040]
  In addition, in FIG. 6, the optimization of the beer sieving classification in the combination of the two-stage fluid drying furnace and the cyclone according to the present invention is shown in a graph. As shown in the graph, when the beer content is dried by this apparatus, some of the fine particles in the primary drying furnace 10 and the secondary drying furnace 20 are scattered and collected by the cyclone 34. Then, apart from the fine particles collected by the cyclone 34 and the coarse particles discharged from the drying furnace, they are provided to a molding machine 39 for a carbonization processing system in a subsequent process. As a result, due to the classification effect of the granular moving bed, it was confirmed by actual tests that the subsequent process was very good.
[0041]
  Next, the dried beer lees (moisture content: 1 to 6%) P3 dried through the drying processing system according to the present invention is put into the molding machine 39, and a binder such as a binder is added. Without being used, it is compressed at a high pressure and formed into a rod-shaped solid body W having a desired shape of a polygonal cylindrical shape. And the bar-shaped solid body W of the beer lees pressure-molded by the molding machine 39 is placed in a row on the tray 40, and carbonized by conveying the tray 40 to the carbonization processing system 200. It is.
[0042]
  As schematically shown in FIG. 7, the carbonization processing system 200 includes a moving carriage 50 on which a plurality of trays 40 on which a plurality of solid bodies W of beer lees are placed in a row are stacked. The movable carriage 50 has an L-shaped configuration including a rising portion 51 that forms a furnace front wall of a carbonization furnace 63 (to be described later) and a tray mounting table 52 that forms a furnace bottom wall. A wheel 53 is provided in the part so that it can move freely. Further, the movable carriage 50 can be driven by a drive mechanism. This drive mechanism is installed outside a drive motor 54 installed at a fixed position (fire extinguishing position) side outside the furnace of the movable carriage 50, a drive pulley 55 driven by this drive motor 54, and the carbonization furnace 63 side. The driven pulley 56 and a roller chain 57 spanned between the pulleys 55 and 56 are driven by the drive motor 54 to move the movable carriage 50 to a fixed position (fire extinguishing position) outside the furnace. ) And a fixed position in the carbonization furnace 63 so as to be reciprocable.
[0043]
  The carbonization apparatus 60 includes a forklift-like gantry 61, a pantograph-type elevating mechanism 62 capable of elevating and lowering the gantry 61, and a carbonizing furnace 63 installed on the upper portion of the gantry 61 that elevates and lowers by the elevating mechanism 62. Have. The carbonization furnace 63 has a box shape in which a part of the front wall portion 63a and the bottom wall portion 63b on the front side is opened in accordance with the L shape of the movable carriage 50, and the upper wall portion thereof. One end of the flue 64 faces 63c. The other end of the flue 64 faces the gas combustion chamber 65, and a combustion burner 66 and a combustion fan 67 that blows combustion air face the gas combustion chamber 65, respectively. The gas generated in the carbonization furnace 63 is completely combusted, and the exhaust gas after combustion is discharged to the outside by an exhaust pipe 68.
[0044]
  On the other hand, the carbonization furnace 63 constituting the carbonization apparatus 60 is provided with a carbonization mechanism 70. The carbonization mechanism 70 includes two carbonization burners 71 facing from the outer wall of the furnace, a first in-furnace blower fan 72 that blows carbonization air into the carbonization furnace 63, and the carbonization furnace 63 during the bricking. It is comprised with the 2nd in-furnace ventilation fan 73 which ventilates the air for bricking. Further, the air blowing pipe of the first in-furnace blower fan 72 branches into a blow-in pipe and a suction pipe through an ejector 74 using the kinetic energy of air in order to stir the furnace atmosphere during carbonization, It has a piping structure that faces the upper and lower parts of the furnace.
[0045]
  In addition, a fire extinguishing box 80 is disposed at a fixed position outside the furnace (fire extinguishing position) of the movable carriage 50, and the fire extinguishing box 80 is suspended by a wire rope 82 wound around a winding drum 81. The fire extinguishing box 80 can be moved up and down by winding and rewinding 82 by forward and reverse rotation of the winding drum 82 by the drive motor 83. And the fire extinguishing box 80 extinguishes and cools the hot coal which carries out the high temperature combustion on the mobile trolley 50 by covering the mobile trolley 50 pulled out from the carbonization furnace 63 by the descending operation after the carbonization is completed. It is like that.
[0046]
  That is, the carbonization processing system 200 described above places the bar-shaped solid body W of the beer lees formed through the drying processing system and the forming step, which are the previous steps, on the tray 40, and puts the tray 40 at a fixed position outside the furnace. Stacks on the tray mounting table 52 of the moving carriage 50 to be stopped. Next, the movable carriage 50 is pulled by driving the drive mechanisms 54, 55, 56, and 57 and moved toward the in-furnace position of the carbonization furnace 63. Then, when the movable carriage 50 reaches the in-furnace fixed position of the carbonization furnace 63, the rising part 51 of the movable carriage 50 and the tray mounting table 52 are located on the front side of the carbonization furnace 63 so as to match the L-shaped form. The front wall portion 63a and the bottom wall portion 63b are fitted in contact with each other with a slight gap to form the front wall portion 63a and the bottom wall portion 63b of the carbonization furnace 63.
[0047]
  At this time, the pantograph type lifting mechanism 62 is operated to raise the movable carriage 50, so that the rising portion 51 and the tray mounting table 52 of the movable carriage 50, the front wall portion 63 a and the bottom wall portion 63 b of the carbonization furnace 63 are The abutting surfaces of the two are brought into close contact with each other in a pressed state and sealed, whereby the carbonizing furnace 63 is closed in a sealed state with the movable carriage 50.
[0048]
  In this state, the carbonization mechanism 70 is operated, and each solid body W placed and accommodated on the movable carriage 50 in the carbonization furnace 63 via the tray 40 is burned at a high temperature. After the high temperature combustion, when the solid body W is carbonized in a predetermined refining process, the elevating mechanism 62 operates to lower the movable carriage 50 and then drive the drive mechanisms 54, 55, 56, 57. The movable carriage 50 is pulled from the inside of the carbonization furnace 63 to a fixed position outside the furnace (fire extinguishing position).
[0049]
  In this way, when the mobile carriage 50 after the completion of carbonization reaches the digestion position, the digestion box 80 descends and is covered with the digestion box 80 so as to enclose the entire mobile carriage 50, thereby The solid W after high-temperature combustion is quickly extinguished and cooled, thereby obtaining fuel charcoal.
[0050]
  Needless to say, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

Moreover, since the temperature of the hot air blown into the drying furnace is controlled to be constant, there is no need to perform heating / cooling of the drying furnace, that is, heating / cooling by accumulating heat of the drying furnace, which is also suitable for energy saving measures. It is.
  Moreover,According to the above configuration, when the internal pressure of the primary drying furnace and the secondary drying furnace becomes unstable due to pulsation and a static pressure difference occurs, the same level is maintained by adjusting the opening of the static pressure adjusting plate. It is possible to adjust, thereby preventing the hot air in one drying oven and the inflow of the beer lees into the other drying oven, so that the fluidized bed of the beer lees in the drying oven is continuously stabilized. Can do. In addition, by closing the supply port side of the secondary drying furnace with a static pressure control plate, the flow between the drying furnaces can be completely shut off, and stable beer when the apparatus is started up (at the start) The soot fluidized bed can be easily and quickly formed in a short time.
[0053]
  In addition,The hot air blowing means includes a combustion burner, a burner fan that supplies combustion air to the combustion burner, and a dilution fan that dilutes the combustion exhaust gas burned in the combustion burner together with the combustion air by the burner fan into an appropriate hot air It is preferable to have an adjustment valve capable of adjusting the amount of hot air diluted by the dilution fan.
[0054]
  According to the above configuration, the hot air temperature and the air volume when the hot air is blown into the drying furnace can be always kept constant and stable.
[0055]
  The second invention isA perforated plate is disposed at the bottom of each drying furnace, and a stirring blade is provided for dividing agglomerated beer lees supplied into the furnace together with hot air blown up through the perforated plate.
[0056]
  According to the above configuration, the agglomeration of the agglomerated beer lees can be enhanced by agitation with the agitation blades, so that the beer lees in the drying furnace can be efficiently fluidized and stable beer lees. The fluidized bed can be easily and quickly formed in a short time.
[0057]
  In addition,Exhaust tubes provided in communication with the upper parts of the drying furnaces are connected to each other by exhaust pipes, and some semi-dried beer cake fine particles scattered along with exhaust gas exhaust from the exhaust pipes are cyclones. CollectGood.
0058]
  According to the above configuration, the dried coarse coarse dried beer is mainly used for the subsequent process by collecting the fine granules of the semi-dried beer lees scattered from the exhaust pipe together with the exhaust gas exhaust. As a result, the forming yield of the dried beer lees can be improved.
