[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a distillation method and a distillation apparatus used therefor.
[0002]
[Prior art]
As a result of the 2001 revision of the liquor tax law, the tax rate for shochu has been raised, and the tax amounts for shochu and whiskey are almost the same. In order to increase the competitiveness of shochu, there is a strong demand for the development of methods and devices that can reduce the production cost of shochu.
[0003]
For example, a single-type distiller such as pot still is used for producing distilled liquors such as otosho shochu. However, the conventional pot still has a problem that the alcohol content of the obtained distilled liquor is low, and a problem that a large amount of steam, cooling water, etc. is used.
[0004]
Therefore, in order to solve such a problem, the present inventor has obtained a post-distilled solution (distillate obtained at the end of one distillation, furfural, diacetyl, Utilizing high-boiling components such as fatty acid esters) and initial distillate (the distillate obtained at the beginning of one distillation, including the soot from the last distillate) A simple shochu distillation apparatus is proposed (Japanese Patent Application No. 4-242765).
[0005]
As shown in FIG. 2, this shochu distillation apparatus is provided with a temperature rising can (pre-distilled can) 52 in front of the distillation can 51, and firstly, a soot 54 is placed in the temperature rising can 52, and then this temperature rising Steam is blown into the can 52, and the distilled vapor evaporated and generated in the temperature rising can 52 is taken out from the temperature rising can 52 and sent to the distillation can 51. At this time, the alcohol content of the fed distillation vapor is observed by the calibrator 53. Then, the temperature of the soot 55 in the distillation can 51 is raised with the above-described distillation vapor. Then, when the calibrator 53 observes that the alcohol content of the distilled vapor has become 0 degree, the distillation vapor is stopped from being fed into the distillation can 51 and steam is blown into it. In the figure, 56 is a condenser, 57 is a product tank, and 58 is a first after distillate tank.
[0006]
[Problems to be solved by the invention]
In this product, the alcohol concentration of the straw 55 in the distillation can 51 can be increased by the distilling vapor (from the temperature rising can 52) sent to the distillation can 51, and compared with the conventional pot still, Increases alcohol content. In addition, the distillation time can be shortened, and the amount of steam, cooling water, etc. used can be reduced. However, due to the revision of the liquor tax law, there is a strong demand for the development of a distillation method and a distillation apparatus that can further reduce production costs.

After introducing the distillation part of the vapor, the distillation waste liquid in the distillation can is extracted and the fermented soot is newly stored in the distillation can. On the other hand, the soot in the temperature-raising can is raised in the heating part. Then, after the temperature rise, the soot in the temperature riser is heated, and the distillation vapor vaporized and generated by this heating is taken out of the temperature riser and introduced into the distillation can. The first distillation method is to raise the temperature of the soot in the newly accommodated distillation can, take out the distilled vapor vaporized by this temperature rise from the distillation can and introduce it into the condenser to condense and liquefy it.

Raise the temperature of the later soot Then, after the temperature rise, the soot in the temperature riser is heated, and the distilled vapor vaporized and generated by this heating is taken out from the temperature riser and introduced into the distillation can. Then, the fermented soot in the distillation can is heated with the introduced distillation vapor, and the distillation vapor is taken out from the distillation can and then introduced into a condenser to be condensed and liquefied. Thus, in the distillation method of the present invention, after distillation portion of the distillation vapor taken out from the distillation can is introduced into the temperature rising can, the temperature after the fermentation in the temperature rising can is raised at the above-mentioned distillation portion. Therefore, the energy for raising the temperature of the soot in the temperature rising can can be reduced, and the time for raising the temperature of the soot in the temperature raising can can be shortened. Moreover, the distillation vapor vaporized and generated in the heating can is introduced into the distillation can, and the soot after fermentation in the distillation can is heated with the introduced distillation vapor, so the distillation of the soot in the distillation can The time (temperature raising time) can be shortened, and the alcohol content of the soot in the distillation can can be increased to increase the alcohol content of the resulting product. Furthermore, since the heating time and distillation time of each soot are shortened, the amount of steam used is reduced correspondingly, resulting in energy saving. Thus, energy saving can be achieved, the alcohol content of the product obtained can be increased, and the manufacturing cost can be reduced. On the other hand, according to the distillation apparatus of the present invention, the distillation method of the present invention can be performed efficiently.

In some cases, distillate vapor is removed from the distillation can while using the soot made of inexpensive raw material (sub-raw material) different from the raw material (main raw material) in the distillation can as the soot in the heating can. The flavor of is left the flavor of the candy in the distillation can. Examples of the main raw material include various raw materials such as rice, wheat, sweet potato, and buckwheat, and examples of the auxiliary raw material include various raw materials such as corn starch, tapioca starch, and other starches or grains.

[0016]
In the above configuration, the product alcohol can be produced, for example, as follows. In this embodiment, distillation in the distillation can 1 and the temperature rising can 2 is performed at normal pressure, heating in the distillation can 1 is performed by indirect heating, and heating in the temperature rising can 2 is performed by indirect heating and direct steam. . First, a temperature rising can containing 醪 B (volume 450 L, ALC 12%) and a distilled alcohol vapor (distilled fraction after distillation) (volume 50 L, ALC 12%) at the previous distillation (in distillation can 1) 2 is heated, and the distilled alcohol vapor (distilled vapor) generated in the temperature rising can 2 is directly introduced into the distillation can 1 containing 醪 A (volume 1000 L, ALC 17%) through the introduction pipe 13. . And the soot A in the distillation can 1 is heated up with the said distilled alcohol vapor. In the heating, steam is supplied into the temperature rising can 2 via the steam supply pipe 10, and the steam supply pipe 10, the first connecting pipe 21, and the second supply are supplied to the temperature rising can heating portion of the temperature rising can 2. This is done by supplying steam through the pipe 16. In this state, the on-off valves 5a, 10a, 13a, 14a, 16a are opened, and the on-off valves 6a, 15a, 17a are closed.
[0017]
Next, the ALC of the distilled alcohol vapor passing through the communication pipe 14 is checked by the sample tester 3, and when the ALC becomes about 6%, the on-off valves 10a and 16a are closed and the heating of the temperature raising can 2 is stopped. At the same time, the on-off valves 13a and 14a are closed, and the introduction of the distilled alcohol vapor into the distillation can 1 is stopped. On the other hand, the on-off valve 15a is opened, steam is supplied to the heating section of the distillation can 1 through the steam supply pipe 10, both the connecting pipes 21, 22, and the first supply pipe 15, and the soot A in the distillation can 1 is removed. Heat. And the distillation alcohol vapor (distillation vapor) produced | generated in the distillation can 1 by this heating is introduce | transduced into the condenser 4, it condenses and liquefies, and it takes out as product alcohol.
[0018]
As a result of the introduction of the distilled alcohol vapor, the distillation can 1 has a volume of 165 L and an ALC of about 36% distilled alcohol vapor introduced into the distillation can 1. %), It becomes the soot (volume 1165 L, ALC 19.6%) during distillation of the still 1. Further, the temperature of the soot during distillation of the distillation can 1 is about 85 ° C. by the distilled alcohol vapor. In this way, the amount of the first soot (醪 A, B and the distilled alcohol vapor at the time of the previous distillation) is 1500 L (1000 L + 500 L), but the amount of soot when the distillation can 1 is distilled is as small as 1165 L. On the other hand, ALC increases, saving energy. In addition, the ALC of the product alcohol is increased and the rectification effect is improved. Although tapioca starch is contained in the auxiliary material, the distilled alcohol vapor generated from the auxiliary raw material 直接 B is directly put into the main raw material 醪 A. Unlike the case where 醪 A and 醪 B are mixed, it does not change much.
[0019]
Next, in the temperature rising can 2, after the distillation of the soot B, the distillation waste liquid is taken out from the take-out valve 27, and the soot B (volume 450 L, ALC 12%) is newly supplied from the auxiliary raw material supply pipe 12. At the end of the distillation in the distillation can 1, when the soot in the distillation can 1 is retained by ALC 20 to 10% (in this embodiment, ALC 15%), the on-off valve 5a is closed and the on-off valve 6a is opened, The post-distilled alcohol vapor flowing through the swan neck 5 is directly introduced into the temperature rising can 2 through the vapor supply pipe 6. And the soot B in the temperature rising can 2 is heated with the said post-distillation alcohol vapor. In addition, the on-off valve 17 a is opened, and steam is supplied into the distillation can 1 through the steam supply pipe 10, the two connecting pipes 21 and 22, and the third supply pipe 17. Then, the introduction is stopped at ALC 8% of the post-alcohol alcohol vapor. At this time, a post-alcohol vapor of about 50 L in volume between ALC 15% and ALC 8% and ALC 12% was introduced into the temperature rising can 2. In addition, the temperature of the soot during distillation in the temperature raising can 2 becomes about 70 ° C. by the above-mentioned distilled alcohol vapor, shortening the next distillation time and saving energy. The soot ALC in the distillation can 1 is detected by a tester (not shown).
[0020]
Next, when the ALC of the soot in the distillation can 1 decreases to a predetermined value (for example, ALC 0%), this is detected by the tester, and the on-off valve 5a is opened and the on-off valves 6a, 15a, 17a are closed. Then, the distillation waste liquid is taken out from the take-out valve 26, and the soot A (volume 1000 L, ALC 17%) is newly supplied from the main raw material supply pipe 11. After that, as described above, the temperature rising can 2 is heated, and the distilled alcohol vapor generated in the temperature rising can 2 by this heating is introduced into the distillation can 1. Such operations are repeated to obtain a desired amount of product alcohol.
[0021]
As described above, in this embodiment, since the distilled alcohol vapor from the distillation can 1 is directly supplied to the temperature rising can 2 to raise the temperature of the soot B in the temperature rising can 2, the temperature rising can 2 In addition to reducing the energy required for raising the temperature of the soot B, the time for raising the temperature of the soot B in the temperature raising can 2 can be shortened. In addition, since distilled alcohol vapor from the heating can 2 is directly supplied to the distillation can 1 to raise the temperature of the soot A in the distillation can 1, the distillation time (temperature raising time of the soot) is shortened. The ALC of 醪 A in the distillation can 1 is increased, and the ALC of the product alcohol is increased accordingly. In addition, since the ALC of 醪 A is increased, the amount of distilled alcohol vapor from the distillation can 1 can be reduced, energy can be saved, and the product alcohol storage tank can be reduced. In this way, manufacturing costs can be reduced while saving energy. Moreover, because rice bran and tapioca starch are used as auxiliary ingredients, the rice shochu-specific flavor (flavor derived from rice) remains.
[0022]
In the above embodiment, distillation is performed at normal pressure. However, the present invention is not limited to this, and distillation may be performed at normal pressure or reduced pressure. The heating method may be either a direct steam method or an indirect heating method.
[0023]
【The invention's effect】
As described above, according to the distillation method of the present invention, the after-distilled portion of the distillation vapor taken out from the distillation can is introduced into the temperature rising can, and the post-fermentation koji in the temperature rising can is raised at the above-mentioned distilling portion. Warm. Therefore, the energy for raising the temperature of the soot in the temperature raising can be reduced, and the time for raising the temperature of the soot in the temperature raising can can be shortened. Moreover, the distillation vapor vaporized and generated in the heating can is introduced into the distillation can, and the soot after fermentation in the distillation can is heated with the introduced distillation vapor, so the distillation of the soot in the distillation can The time (temperature raising time) can be shortened, and the alcohol content of the soot in the distillation can can be increased to increase the alcohol content of the resulting product. Furthermore, since the heating time and distillation time of each soot are shortened, the amount of steam used is reduced correspondingly, resulting in energy saving. Thus, energy saving can be achieved, the alcohol content of the product obtained can be increased, and the manufacturing cost can be reduced. On the other hand, according to the distillation apparatus of the present invention, the distillation method of the present invention can be performed efficiently.
[0024]
In the present invention, after heating the soot in the distillation can with the distillation vapor from the above-mentioned temperature rising can, this soot may be heated and the distillation vapor may be vaporized by this heating.
[0025]
Further, in the present invention, as the soot in the temperature raising can, a soot of a different kind from the soot in the distillation can is used, and the flavor of the distilled vapor taken out from the distillation can leaves the flavor of the soot in the distillation can. In some cases, distillate vapor is removed from the distillation can while using the soot made of inexpensive raw material (sub-raw material) different from the raw material (main raw material) in the distillation can as the soot in the heating can. The flavor of is left the flavor of the candy in the distillation can.
