Field of the Invention The present invention relates to a method for cooling a steam containing a hiba oil component contained in a raw material of a hiba wood to produce a liquid containing hiba oil and separating the hiba oil from the liquid. And a cooling / separating device for removing hiba oil.

[0002]

2. Description of the Related Art In general, it is known that hiba wood contains useful chemical components such as hinokitiol which exhibit excellent properties such as antibacterial properties. In recent years, these components have low toxicity to the human body. For this reason, so-called hiba oil containing these components has been rapidly extracted from hiba wood and used as it is or further separated into single components for use in various fields.

Conventionally, when extracting hiba oil from hiba wood, for example, a raw material such as sawdust of hiba wood is housed in a container and hermetically sealed. Hiba oil component contained in water is extracted by taking in steam. Then, the steam into which the hiba oil component is taken is passed through one cooling pipe, and the cooling pipe is cooled with water to a liquid containing hiba oil, and the liquid is left to evaporate the hiba oil. It was separated and the supernatant of hiba oil was taken out (see, for example, JP-A-2-60997). The extraction rate of hiba oil is about 1.0-1.
In order to increase the amount of extraction, in recent years, a large apparatus capable of processing, for example, about 1.5 tons (about 6 m ³ ) of sawdust at one time has been used. Has become.

[0004]

However, in such conventional extraction of hiba oil, as the size of the apparatus increases, cooling with one cooling pipe is inferior in processing capacity and processing efficiency is poor. There was a problem. In addition, since the use of cooling water is used only for cooling, there is a problem that the use efficiency is poor.

The present invention has been made in view of the above-mentioned problems, and has been made to improve the processing efficiency by increasing the processing capacity of steam, and to effectively utilize the cooling water for extracting hiba oil. An object of the present invention is to provide a cooling / separating device for removing hiba oil.

[0006]

The technical means of the present invention for achieving the above object is to cool hiba oil by cooling steam containing hiba oil component contained in a raw material of hiba wood. In a cooling separation device for extracting hiba oil, comprising: a cooling unit that converts the liquid cooled by the cooling unit into a liquid containing hiba oil; and a separating unit that extracts hiba oil from the liquid cooled by the cooling unit. A water tank having a mouth and an outlet, a plurality of spirally wound cooling pipes provided in the water tank and through which the steam passes, a delivery pipe for sending steam to each cooling pipe, and cooled by each cooling pipe. And a discharge pipe that collects and discharges the collected liquid, wherein the separation unit is a collection container that receives the liquid discharged from the discharge pipe, and a separation unit that is separated in the collection container at a lower part of the collection container. An inlet into which water enters, and the separated water is located at a predetermined height of the collection container. A separated water discharge pipe opened and closed by a first valve having a mouth, and a second valve provided at a predetermined height position of the recovery container and discharging the hiba oil separated in the recovery container from the height position. It is provided with a hiba oil discharge pipe that is opened and closed, and a water supply pipe that is opened and closed by a third valve that supplies water in the water tank from the water tank of the cooling unit to the lower part of the recovery container. And, if necessary, the collection container is formed of a transparent member.

[0007]

According to the cooling / separating apparatus for removing hiba oil having such a configuration, in the water tank of the cooling unit, the cooling water is supplied from the supply port and discharged from the discharge port to cool the internal cooling pipe. . In this state, the steam in which the Hiba oil component is taken in is sent out to the delivery pipe and flows into each cooling pipe, so that the steam is cooled, so that the steam is condensed and changes into a liquid containing Hiba oil. The liquid is collected in a discharge pipe to which each cooling pipe is connected, and is collected from the discharge pipe to a collection container in the separation unit. In this cooling, since a plurality of cooling pipes are provided, the contact ratio of the cooling pipes to the cooling water increases,
Processing efficiency is improved.

In the separating section, for example, hiba oil is taken out as follows. First, the first valve is kept open. In this state, when the liquid is discharged from the discharge pipe to the collection container and accumulates in the collection container, the liquid stays in the collection container. And two layers of water. Then, when the liquid level reaches the predetermined height of the collection container, the first
Is opened, the water separated downward is discharged from the separated water discharge pipe, whereby the ratio of hiba oil to water increases while the liquid level maintains a predetermined height.

[0009] Then, if hiba oil has accumulated to some extent,
The discharge of the liquid from the discharge pipe is stopped, and the discharge of the water separated downward is stopped by closing the first valve. In this state, the third valve is opened. Thereby, the water from the water tank is supplied from the water supply pipe, and accumulates below the collection container. Therefore, the liquid level rises in a state where the hiba oil and the water are separated. Then, when the lowermost end of the hiba oil layer reaches the predetermined height position, the third valve is closed and the supply of water from the water tank is stopped. Next, the second valve is opened. Thus, only the hiba oil having a liquid level higher than the predetermined height position is discharged from the hiba oil discharge pipe, and the hiba oil is taken out.

Two hiba oil component extracting devices T are connected, and steam containing hiba oil components is supplied from the hiba oil component extracting device T. In the hiba oil component extraction device T, the hiba oil component is extracted as follows. First, the support shaft 22 is moved upward by the jack 25 of the cover moving mechanism 24 to raise the lid 9, and the support shaft 22 is rotated by operating the handle 26,

In a normal position. In this state, as shown in FIG. 10A, the raw material H such as sawdust is transferred from the inlet / outlet 8 of the container 5 to the container 5 by a belt conveyor or the like.
Supply within.

When the required amount of the raw material body H is stored in the container 5, the operation of the handle 26 of the lid moving mechanism 24 causes the support shaft 2 to move.
2 is rotated, as shown in FIG. 7 and FIG.
The lid 9 is moved from the open position B onto the entrance 8 of the container 5,
The support shaft 22 is moved down by the jack 25 to lower the lid 9 to the closed position A, and the lid 9 is closed by the clamp device. In this state, as shown in FIG.
Water vapor is blown from the steam blowing port 30 through the supply pipe 31. Water vapor is, for example, at a pressure of 2 kg / cm ² ,
The temperature is set to 90 ° C. Thereby, the water vapor
Ascending through the stored raw material body H, the steam outlet portion 36
Is discharged through the discharge pipe 37. In this process, the raw material H is heated by the steam, so that the hiba oil component contained in the raw material H is taken into the steam and discharged to the cooling / separating device K together with the steam.

Next, the operation of the cooling / separating apparatus K for extracting hiba oil according to the embodiment will be described. In the water tank 41 of the cooling section 40 of the cooling separation device K, cooling water is supplied from a supply port 42 and discharged from a discharge port 43 to cool an internal cooling pipe 45. The steam from the hiba oil component extraction device T is sent to the delivery pipe 46 through the discharge pipe 37 connected to the steam discharge port 36, and flows to each cooling pipe 45. As a result, the steam is cooled, so that the steam is condensed and changes into a liquid containing hiba oil. This liquid is collected in the discharge pipes 47 to which the cooling pipes 45 are connected. Collected in 50 collection containers 51. In this cooling, since a plurality of cooling pipes 45 are provided,
Since the contact ratio of the cooling pipe 45 to the cooling water is increased, the processing capacity of the cooling pipe 45 is increased, and the processing efficiency is improved.

In the separating section 50, for example, separation is performed as follows. As shown in FIG. 3A, first, the first and fourth valves V1 and V4 are opened,
The second and third valves V2 and V3 are closed. Thereby, as shown in FIG. 4A, the liquid is discharged from the discharge pipe 47 to the collection container 51 and accumulates in the collection container 51. In the collection container 51, the liquid stays, and since the specific gravity of the hiba oil is smaller than that of water, the liquid is separated into two layers of hiba oil and water. In this state, the liquid level rises, and FIG.
As shown in (b), the liquid level is a predetermined height h of the collection container 51.
If it is, since the first valve V1 is open, the lower separated water W is discharged from the separated water discharge pipe 52,
Thereby, the ratio of the hiba oil C to the separation water W increases while the liquid level maintains the predetermined height h.

Then, if a certain amount of hiba oil has accumulated,
As shown in FIG. 3B, the discharge of the liquid is stopped by closing the fourth valve V4, and the discharge of the water separated downward is stopped by closing the first valve V1. Further, the third valve V3 is opened. Thereby, as shown in FIG. 4C, the water from the water tank 41 is supplied from the water supply pipe 54 and accumulates below the recovery container 51. Therefore, the liquid level rises in a state where the hiba oil C and the water W are separated. Then, when the lowermost end of the layer of hiba oil C reaches the above-mentioned predetermined height h, the third valve V3 is closed and the supply of water from the water tank 41 is stopped. In this case, since the collection container 51 is transparent, the layer of hiba oil C can be visually observed, and can be reliably stopped at the predetermined height h. Further, in this case, since the supply of water is supplied from the water tank 41, there is no waste and the utilization efficiency of the cooling water is improved.

Next, as shown in FIG. 3 (3), the second valve V2 is opened. Thereby, as shown in FIG. 4D, only the hiba oil having a higher liquid level than the predetermined height h is discharged from the hiba oil discharge pipe 53, and the hiba oil C is taken out.
When the hiba oil C is taken out, as shown in FIG. 3A, the second valve V2 is closed, and the first and fourth valves V4 are closed.
Is opened, the liquid is again discharged from the discharge pipe 47 to the collection container 51, and the hiba oil is collected by the same operation as described above.

On the other hand, in the hiba oil component extraction device T,
After steam is blown for an appropriate time to extract the hiba oil component, the residue of the raw material H in the container 5 is taken out. At this time, first, the jack 25 of the lid moving mechanism 24
2 is moved upward to raise the lid 9, and the support shaft 22 is rotated by operating the handle 26 to move the lid 9 from the closed position A to the open position B as shown in FIG. 7 and FIG. Keep it. Next, as shown in FIG. 5, a truck or the like is stopped on the tilting side of the container 5, and the electric motor 14 of the drive mechanism 13 is operated to tilt the container 5 as shown in FIG. Thereby, the raw material body H falls from the entrance 8 and is discharged to the bed of the truck.

In this case, since the lid 9 is supported by the machine frame 1, the handling of the lid 9 is easier than in the case where the lid 9 is detached and grounded, thereby improving the operability. Also, since the drive mechanism 13 operates the electric motor 14,
The operation is simpler than the manual operation, and the operability is also good in this respect. In addition, the raw material body H can be dropped and taken out only by operating the drive mechanism 13 and tilting the container 5, so that the raw material body H can be taken out extremely easily. Therefore, it can be taken out in a short time.

When the removal is completed, the next raw material H is supplied again with the container 5 in the normal position as described above.
The extraction process is performed in the same manner as described above. in this case,
Since the operation of removing the raw material H is performed in a short time, the number of times of processing per day can be increased, so that the yield can be increased and the processing efficiency of the raw material H can be greatly improved.

In the above embodiment, the number of cooling pipes 45 is not limited to the one described above, but may be appropriately provided. In the separation section 50, each of the valves V1, V
The opening / closing timings of 2, V3 and V4 are not limited to those described above, and it goes without saying that the opening / closing may be appropriately performed according to the situation. In the above-mentioned hiba oil component extraction device T, the lid support mechanism 20 is not limited to the above-described one. For example, as shown in FIG. It may be opened and closed by a mechanism, and may be changed as appropriate. Also,
The drive mechanism 13 is not limited to the chain transmission mechanism 15, and may be appropriately changed, for example, using a gear transmission mechanism.
In addition, the driving mechanism 13 uses the electric motor 14, but is not necessarily limited to this, and the rotating shaft 1 is manually operated.
1 may be rotated, and may be changed as appropriate.

[0033]

As described above, according to the cooling / separating apparatus for removing hiba oil according to the present invention, since a plurality of cooling pipes are provided, the contact ratio of the cooling pipes to the cooling water is increased.
Since the processing capacity of the cooling pipe is increased, the processing efficiency can be improved. Therefore, it is possible to cope with an increase in the size of the device. Further, when the hiba oil is taken out, the water is supplied to the recovery container from the water tank, so that there is an effect that the use efficiency of the cooling water can be improved without waste. Further, since the separating portion of the cooling / separating device has a simple structure in which the hiba oil is taken out by opening and closing the valve, the mounting is simple and the cost can be reduced.

Further, when the recovery container of the separation section is formed of a transparent member, the separated state and the liquid level of the liquid can be determined at a glance, so that the valve operation can be performed reliably.
