Description

[Detailed explanation of the idea]

[Industrial Field of Application] The present invention is used for fermentation of distilled spirits such as shochu, whiskey, brandy, etc., and isoamyl alcohol, propanol, butanol,
The present invention relates to a single distillation device for distilled spirits that includes a device for removing high-boiling components such as furfural. [Conventional technology and its problems] Alcohol vapor generated by boiling fermented mash contains substances such as isoamyl alcohol, propanol, butanol, and furfural, which have a boiling point of around 97°C to 132°C, and which deteriorate the taste and aroma of alcoholic beverages. Contains high boiling point components. However, in conventional single distillation equipment, the alcohol vapor generated in the still can is sent directly to the pseudo-condenser and cooled to obtain unprocessed sake, which does not remove high-boiling components and makes it difficult to obtain products with good taste and aroma. It was. Therefore, various efforts have been made to obtain high-quality products from which high-boiling components have been removed using single distillation equipment. For example, one such device is a single distillation system in which high-boiling components are removed in the distillation shelf by installing a rectification shelf above the distillation can and sending the alcohol vapor through the distillation shelf to the condenser. The device is well known. However, with this method, the structure of the equipment becomes complicated, and high-boiling components tend to remain in the rectifying shelf, and these remaining high-boiling components mix into the next distilled alcoholic vapor, resulting in the product being contaminated. This often results in poor quality. Furthermore, in a single distillation device, a certain amount of fermentation mash is stored inside the still can and boiled, so the components of the alcoholic spirit vapor that evaporates from the fermentation mash change as it boils, and the amount of high boiling point components in this alcoholic vapor changes. also changes. Therefore, unless the amount of high-boiling components removed is also changed along with this change, there is a drawback that the quality of the distilled liquor will not be constant. [Means for Solving the Problems] The present invention was devised to solve the above problems, and includes a distillation can that generates alcoholic vapor by boiling a stock solution of fermented moromi containing alcoholic ingredients. , a single distillation device for distilled spirits equipped with a condenser that cools alcohol vapor to obtain raw liquor, which has a jacket part on a part of the peripheral wall to which cooling water is supplied, and high boiling point components contained in alcohol vapor. A cyclone-type collector for condensing and removing the high-boiling components is provided in the middle of the path from the still to the condenser, and a path is provided for refluxing the high-boiling components from the collector to the still. be. [Function] In the single distillation apparatus configured as described above, the alcoholic spirit vapor generated by boiling the fermented mash inside the still reaches the inside of the collector. By cooling this alcohol vapor with the cooling water supplied into the jacket portion of the collector, high boiling point components in the alcohol vapor are separated, that is, liquefied, and removed from the alcohol vapor. The removed high-boiling components are refluxed to the still via a reflux route. Alcohol vapor from which high-boiling components have been removed is cooled in a condenser and becomes unprocessed sake. [Example] Hereinafter, an example of the present invention will be described based on the drawings. The vacuum type single distillation apparatus 10 of the present invention has the following structure. 12 is a distiller that boils the stock solution A containing the alcohol components of the fermented moromi to generate alcohol vapor; 16 is a cyclone-type collector that removes high-boiling components from the alcohol vapor;
18 is a condenser that condenses alcohol vapor to obtain distilled liquor. The distillation can 12 and the collector 16 are connected by a swan neck-shaped steam discharge passage 14a, and the collector 1
6 and the condenser 18 are connected by a steam exhaust path 14b. At the top of the distillation can 12, there is provided an inlet 26 for supplying the stock solution A of fermentation mash. A jacket heating section 28 is provided by duplicating the structure of the peripheral wall of the distillation can 12, and steam heated to a high temperature is sent to the jacket heating section 28 from a steam supply pipe 30 to heat the inside of the distillation can 12. Further, a coil-type heating pipe 32 through which heated steam circulates is provided inside the distiller 12. And these jacket heating parts 2
8 and a heating tube 32 to evenly boil the fermentation mash stock solution A. Note that the water vapor that has circulated through the jacket heating section 28 is discharged from the steam drain 34. The circumferential wall of the collector 16 has a double structure and a jacket cooling section 36 is provided. Cooling water is supplied into the jacket cooling section 36 from a water supply pipe 38 and circulated, thereby cooling the inside of the collector 16. This cooling water can be discharged from the drain pipe 40. In addition, at the bottom, there is a reflux path 42 for returning liquid condensed from alcohol vapor to the inside of the distillation can 12.
has been established. A cooling pipe 20 is provided inside the condenser 18, and while alcohol vapor flows through the cooling pipe 20, it is cooled by cooling water and condensed. Further, a product tank 22 is connected to the condenser 18, and a product tank 22 is connected to the condenser 18.
The distilled liquor condensed by 8 is transferred to this product tank 22.
is stored in From the distillation can 12 to the product tank 2 via the condenser 18
By connecting a vacuum pump 24 to a part of the distillation route leading to the product tank 22, for example, in the illustrated case, a part of the product tank 22, the distillation route can be brought into a reduced pressure state and distillation can be carried out. Hereinafter, a distillation operation using the distillation apparatus 10 having the above configuration will be explained. With the required amount of undiluted shochu liquor A stored in the still can 12, water vapor at a gauge pressure of 0.3 kg/cm ² to 3 kg/cm ² is supplied to the heating tube 32 and the jacket heating section 28, which are heating sources, to heat it. , Boil the stock solution A evenly. Alcohol vapor generated by boiling is passed through steam exhaust path 1.
It enters the collector 16 through 4a. Since the inside of the collector 16 is cooled by the cooling water flowing inside the jacket cooling section 36, first, high boiling point components in the alcoholic spirit vapor are condensed and fractionated from the alcoholic vapor. The main high-boiling components are isoamyl alcohol, propanol, butanol, furfural, etc., each having a boiling point of about 97°C to 132°C. In addition, medium-boiling components such as esters and low-boiling components such as acetaldehyde are also fractionated. In addition, distillation can 1
The air that increased from 2 is also condensed. Since the present invention is a single distillation device, a certain amount of fermented mash A is stored inside the still can 12 and boiled. Therefore, the components of the alcohol vapor that evaporate change with the boiling time, and the amount of high-boiling components also changes. For this reason, the quality of the obtained shochu will not be constant unless the amount of high-boiling components to be removed is changed. change the amount of In this case, since the amount and temperature of the cooling water can be easily controlled, high quality shochu can be easily obtained. Condensed liquid high-boiling components, etc. are collected in the collector 1.
It is returned to the stock solution A of shochu moromi inside the distillation can 12 through a reflux path 42 provided at the bottom of the shochu moromi 6. and,
Among these high boiling point components, the effective liquor components are boiled again inside the still can 12 and turned into liquor vapor, so that the undiluted solution A of shochu moromi can be efficiently distilled without waste. The removed high-boiling components are refluxed and sent to the collector 1.
6, and will not mix with the alcoholic spirit vapor to be distilled next and deteriorate the quality of shochu. The alcohol vapor from which the high boiling point components have been fractionated enters the condenser 18 through the vapor discharge path 14b, where it is cooled and condensed to become a distillate, that is, a shochu product. This shochu product is sent to a product tank 22 and stored therein. This distillation path is maintained in a reduced pressure state close to vacuum by a vacuum pump 24, so that the distillation can 1
If the stock solution A inside No. 2 is boiled at a heating temperature of 45°C to 60°C, distillation will be carried out well. Distillation apparatus 1 of the present invention connected to the collector 16
0, and shochu produced by a conventional distillation apparatus in which the collector 16 is not connected and the steam dischargers 14a and 14b are directly connected, the high boiling point components contained in these shochu Table 1 shows the results of a comparative analysis of , medium-boiling point components, respectively.

Table 1 shows that the alcohol distillation device 10 of the present invention can remove high-boiling point components, medium-boiling point components, and low-boiling point components from alcohol vapor better than the conventional distillation device that is not equipped with a collector 16, and as a result, it improves the taste. You can get shochu with a good aroma. In this embodiment, a vacuum-type single distillation apparatus equipped with a vacuum pump 24 has been described, but the present invention is not limited to this, and the present invention can also be used in an ordinary-pressure single-type distillation apparatus with good results similar to the vacuum distillation apparatus. is obtained. In this case, the means for heating the stock solution A of the fermentation mash inside the still is a means for directly blowing heated steam into the stock solution A, instead of the jacket heating section 28 and the heating tube 32 of the previous embodiment.
