Description

本発明は、単式蒸留方法およびそれに用いる装置に関するものである。   The present invention relates to a single distillation method and an apparatus used therefor.

平成１８年の酒税法の改正により、焼酎の税率が上げられ、焼酎とウィスキーの税額が同じ金額になっている。そこで、焼酎の競争力を付けるため、焼酎の製造コストを下げることのできる方法，装置の開発が強く要望されている。例えば、単式蒸留焼酎等の蒸留酒の製造に、ポットスチル等の単式蒸留機が使用されている。ところが、従来のポットスチルでは、得られる蒸留酒のアルコール度数が低いという問題や、蒸気，冷却水等の使用量が多いという問題がある。   As a result of the revision of the Liquor Tax Law in 2006, the tax rate for shochu has been raised, and the tax amount for shochu and whiskey has become 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. For example, a single-type distiller such as a pot still is used for producing a distilled liquor such as a single-distilled 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.

そこで、このような問題を解消するため、本発明者は、従来のポットスチルでは分留していた後留液（１回の蒸留の終わりに得られる留出液であり、フルフラール，ジアセチル，高級脂肪酸エステル等の高沸点成分が多量に混じっている）や初留液（１回の蒸留の初めに得られる留出液であり、前回の後留液の滓等が含まれている）を活用するようにした単式の焼酎蒸留装置を提案している（例えば、特許文献１参照）。   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 single shochu distillation apparatus is proposed (see, for example, Patent Document 1).

この焼酎蒸留装置は、図２に示すように、蒸留缶３１の手前に昇温缶（前置蒸留缶）３２を設け、まず、昇温缶３２内に醪３４を入れ、ついで、この昇温缶３２内に蒸気を吹き込み、昇温缶３２内で気化生成される留出ベーパーを昇温缶３２から取り出して蒸留缶３１に送り込み、上記留出ベーパーで蒸留缶３１の内の醪３５を昇温させる。このとき、上記送り込んだ留出ベーパーのアルコール度数を検度器３３で観測する。そして、上記留出ベーパーのアルコール度数が０になったことを検度器３３で観測すると、蒸留缶３１に上記留出ベーパーを送り込むことを止め、蒸気を吹き込むようにする。図において、３６は凝縮器、３７は製品タンク、３８は初後留液タンクである。
特開平６−６２８２６号公報 As shown in FIG. 2, this shochu distillation apparatus is provided with a temperature rising can (pre-distilled can) 32 in front of the distillation can 31, and firstly put a straw 34 in the temperature rising can 32, and then this temperature rising Steam is blown into the can 32, and the distilled vapor vaporized and generated in the temperature rising can 32 is taken out from the temperature rising can 32 and sent to the distillation can 31. Let warm. At this time, the alcohol content of the fed distillation vapor is observed by the calibrator 33. When the alcohol 33 of the distillation vapor is observed with the calibrator 33, the distillation vapor is stopped from being fed into the distillation can 31 and steam is blown into it. In the figure, 36 is a condenser, 37 is a product tank, and 38 is a first after distillate tank.
JP-A-6-62826

この焼酎蒸留装置では、蒸留缶３１に送り込んだ留出ベーパーにより蒸留缶３１内の醪３５のアルコール濃度を高めることができ、従来のポットスチルに比べ、得られる蒸留酒のアルコール度数が高くなる。また、蒸留時間を短縮することができ、蒸気，冷却水等の使用量が少なくてすむ。しかしながら、上記の酒税法の改正により、さらに製造コストを下げることのできる蒸留方法および蒸留装置の開発が強く要望されている。   In this shochu distillation apparatus, the alcohol concentration of the straw 35 in the distillation can 31 can be increased by the distilled vapor fed to the distillation can 31, and the alcohol content of the obtained distilled liquor is higher than that of the conventional pot still. 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.

本発明は、このような事情に鑑みなされたもので、省エネルギー化および製品量のアップを図ることにより製造コストを下げることのできる単式蒸留方法およびそれに用いる装置の提供を目的とする。   The present invention has been made in view of such circumstances, and an object of the present invention is to provide a single distillation method and an apparatus used therefor that can reduce the manufacturing cost by saving energy and increasing the amount of products.

上記の目的を達成するために、本発明は、常圧蒸留缶と昇温缶と減圧蒸留缶とを備え、常圧蒸留缶内に収容した醗酵後の醪を加熱し、この加熱により気化生成された留出アルコールベーパーを常圧蒸留缶から取り出して昇温缶の外周部に案内し、この昇温缶内に収容した醗酵後の醪を上記留出アルコールベーパーで間接加熱したのち、この留出アルコールベーパーを冷却器に導入して冷却，液化し、上記留出アルコールベーパーの間接加熱により昇温缶内で気化生成された留出アルコールベーパーを減圧蒸留缶内に導入し、この導入した留出アルコールベーパーで、減圧蒸留缶内に収容した醗酵後の醪を昇温させ、この昇温により気化生成された留出アルコールベーパーを減圧蒸留缶から取り出し、凝縮器に導入して凝縮，液化するようにした単式蒸留方法を第１の要旨とする。   In order to achieve the above object, the present invention comprises an atmospheric distillation can, a temperature rising can, and a vacuum distillation can, and heats the fermented ferment contained in the atmospheric distillation can and vaporizes and generates by this heating. The distilled alcohol vapor thus removed is taken out from the atmospheric distillation can, guided to the outer periphery of the temperature rising can, and the fermented ferment stored in the temperature rising can is indirectly heated with the distilled alcohol vapor. The distilled alcohol vapor was introduced into a cooler, cooled and liquefied, and the distilled alcohol vapor evaporated and generated in the temperature rising can by indirect heating of the distilled alcohol vapor was introduced into the vacuum distillation can. The temperature of the fermented soot stored in the vacuum distillation can is raised with the distilled alcohol vapor, and the distilled alcohol vapor evaporated by this temperature rise is taken out from the vacuum distillation can and introduced into the condenser to condense and liquefy. Like The simplex distillation process to the first aspect.

また、本発明は、常圧蒸留缶と、昇温缶と、減圧蒸留缶と、上記常圧蒸留缶内の醗酵後の醪を加熱する加熱手段と、上記常圧蒸留缶内の醪を蒸留して得られた留出アルコールベーパーを導入して上記昇温缶内の醗酵後の醪を間接加熱するために上記昇温缶の外周部に形成された間接加熱部と、上記常圧蒸留缶内の醪を蒸留して得られた留出アルコールベーパーを上記常圧蒸留缶から取り出して上記間接加熱部に案内する案内路と、冷却器と、上記間接加熱部を経由した留出アルコールベーパーを冷却器に送給する送給路と、上記昇温缶内の醪を蒸留して得られた留出アルコールベーパーを上記昇温缶から取り出して減圧蒸留缶内に導入する第１導入路と、凝縮器と、上記減圧蒸留缶内の醗酵後の醪を蒸留して得られた留出アルコールベーパーを上記減圧蒸留缶から取り出して凝縮器に導入する第２導入路とを備えた単式蒸留装置を第２の要旨とする。   Further, the present invention includes an atmospheric distillation can, a temperature rising can, a vacuum distillation can, a heating means for heating the fermented ferment in the atmospheric distillation can, and the soot in the atmospheric distillation can. Indirect heating portion formed on the outer peripheral portion of the temperature rising can in order to indirectly heat the fermented rice cake in the temperature rising can by introducing the distilled alcohol vapor obtained in the above, and the atmospheric distillation can A distillate alcohol vapor obtained by distilling the soot inside is taken out from the atmospheric distillation can and guided to the indirect heating unit, a cooler, and a distillate alcohol vapor via the indirect heating unit. A feeding path for feeding to the cooler; a first introduction path for taking out the distilled alcohol vapor obtained by distilling the soot in the temperature rising can from the temperature rising can and introducing it into the vacuum distillation can; A condenser and a distilled alcohol vapor obtained by distilling the fermented rice cake in the vacuum distillation can The simplex distillation apparatus and a second introduction path for introducing the condenser was removed from the vacuum distillation can the second aspect.

本発明の単式蒸留方法では、常圧蒸留缶内で醪を常圧蒸留して得られた留出アルコールベーパーを冷却器に導入して冷却，液化し、製品（液体アルコール）を得ているだけでなく、上記留出アルコールベーパーを、冷却器に導入する前に、昇温缶内の醪を間接加熱するための熱源として利用している。また、この間接加熱により、昇温缶内で醪を蒸留して得られた留出アルコールベーパーを、（常圧蒸留缶，昇温缶に比べて低温で蒸留することができる）減圧蒸留缶内に導入して減圧蒸留缶内の醪を昇温させ、この昇温により、減圧蒸留缶内で醪を減圧蒸留して得られた留出アルコールベーパーを凝縮器に導入して凝縮，液化し、製品（液体アルコール）を得るようにしている。このように、本発明の単式蒸留方法では、昇温缶内で気化生成した留出アルコールベーパーを減圧蒸留缶に導入しているため、減圧蒸留缶内の醪のアルコール度数を高めて、得られる製品のアルコール度数を高くすることができる。しかも、常圧蒸留缶内で醪を常圧蒸留するのに必要なスチーム等の加熱手段だけで、常圧蒸留缶内の醪だけでなく、昇温缶および減圧蒸留缶内の醪をも蒸留することができ、スチーム等の使用量が一般の蒸留機の１／２以下となり、大幅な省エネルギーになる。しかも、常圧蒸留と減圧蒸留との双方により製品を得ることができ、製造量がアップする。さらに、常圧蒸留缶内で醪を常圧蒸留して得られた留出アルコールベーパーを昇温缶の外周部の間接加熱部に送給したのち、冷却器に導入して製品を得るようにしているため、常圧蒸留用コンデンサ（凝縮器）を必要とせず、ランニングコストが安価になる。一方、本発明の単式蒸留装置によれば、本発明の単式蒸留方法を効率よく行うことができる。なお、本発明において、「昇温缶の外周部に形成された間接加熱部」とは、昇温缶の外周面に一体に間接加熱部が形成されている場合だけでなく、昇温缶の外周面から所定の距離離間した状態で間接加熱部が形成されている場合をも含む意味である。   In the single distillation method of the present invention, a distilled alcohol vapor obtained by atmospheric distillation of soot in an atmospheric distillation can is introduced into a cooler and cooled and liquefied to obtain a product (liquid alcohol). Instead, the distillate alcohol vapor is used as a heat source for indirectly heating the soot in the temperature riser before it is introduced into the cooler. In addition, by this indirect heating, distilled alcohol vapor obtained by distilling soot in a heating can can be distilled at a lower temperature than an atmospheric distillation can and a heating can. To increase the temperature of the soot in the vacuum distillation can, and with this temperature increase, the distilled alcohol vapor obtained by vacuum distillation of the soot in the vacuum distillation can is introduced into the condenser to condense and liquefy, I try to get a product (liquid alcohol). Thus, in the single distillation method of the present invention, since the distilled alcohol vapor vaporized and generated in the temperature rising can is introduced into the vacuum distillation can, it can be obtained by increasing the alcohol content of the soot in the vacuum distillation can. The alcohol content of the product can be increased. Moreover, not only the steam in the atmospheric distillation can, but also the soot in the heating and vacuum distillation cans is distilled only by heating means such as steam necessary for atmospheric distillation of the soot in the atmospheric distillation can. Therefore, the amount of use of steam or the like is ½ or less of that of a general distiller, which greatly saves energy. Moreover, a product can be obtained by both atmospheric distillation and vacuum distillation, and the production amount is increased. In addition, after the distilled alcohol vapor obtained by atmospheric distillation of soot in an atmospheric distillation can is fed to the indirect heating section on the outer periphery of the heating can, it is introduced into a cooler to obtain a product. Therefore, a condenser for atmospheric distillation (condenser) is not required, and the running cost is reduced. On the other hand, according to the single distillation apparatus of the present invention, the single distillation method of the present invention can be performed efficiently. In the present invention, the “indirect heating portion formed on the outer peripheral portion of the temperature rising can” refers not only to the case where the indirect heating portion is integrally formed on the outer peripheral surface of the temperature rising can, This also includes the case where the indirect heating unit is formed in a state of being separated from the outer peripheral surface by a predetermined distance.

上記の構成において、製品アルコールをつぎのようにして製造することができる。この実施の形態では、常圧蒸留缶１での蒸留は常圧（１０１．３ｋＰａ〔１気圧〕程度）で行い（蒸留温度：９０〜１００℃）、昇温缶２での蒸留は減圧（２０．２６〔２／１０気圧〕ｋＰａ程度）で行い（蒸留温度：６０℃）、減圧蒸留缶３での蒸留は減圧（１０．１３ｋＰａ〔１／１０気圧〕程度）で行う（蒸留温度：４５℃）。なお、常圧蒸留において、蒸留の始まりでは、アルコール濃度１６ｖｏｌ％で沸点９０℃であるが、蒸留によりアルコール濃度が下がるとともに、沸点が上がり、蒸留の終わりでは、アルコール濃度０ｖｏｌ％となり（すなわち、水となり）、沸点１００℃になる。また、２０．２６ｋＰａでは、水の沸点もアルコール濃度１６ｖｏｌ％の醪の沸点も殆ど同じになる。   In the above configuration, the product alcohol can be produced as follows.

In atmospheric distillation, the boiling point is 90 ° C. at an alcohol concentration of 16 vol% at the beginning of distillation, but the alcohol concentration is lowered and the boiling point is increased by distillation, and the alcohol concentration becomes 0 vol% at the end of distillation (that is, water). And a boiling point of 100 ° C. At 20.26 kPa, the boiling point of water and the boiling point of soot having an alcohol concentration of 16 vol% are almost the same.

また、常圧蒸留缶１での加熱は直接加熱および間接加熱により行い、昇温缶２での加熱は間接加熱により行う。すなわち、常圧蒸留缶１での加熱は、常圧蒸留缶１の内部および常圧蒸留缶加熱部１ｅにスチームを供給することにより行い、昇温缶２での加熱は、昇温缶２の昇温缶加熱部２ｅに留出アルコールベーパーを供給することにより行う。なお、減圧蒸留缶３では、加熱は行わず、留出アルコールベーパー導入による昇温のみを行う。   Moreover, the heating in the atmospheric distillation can 1 is performed by direct heating and indirect heating, and the heating in the temperature rising can 2 is performed by indirect heating. That is, heating in the atmospheric distillation can 1 is performed by supplying steam to the inside of the atmospheric distillation can 1 and the atmospheric distillation can heating unit 1e, and heating in the heating can 2 is performed in the heating can 2. This is performed by supplying distilled alcohol vapor to the heating can heating unit 2e. In the vacuum distillation can 3, heating is not performed, but only temperature rise by introducing distilled alcohol vapor is performed.

まず、醪Ａ（２２５０リットル，アルコール濃度１６ｖｏｌ％を収容した常圧蒸留缶１を加熱手段で加熱し、この加熱により常圧蒸留缶１内で気化生成した留出アルコールベーパー（温度９０〜１００℃）をベーパー案内管１４を介して、醪Ｂ（１５００リットル，アルコール濃度１６ｖｏｌ％）を収容した昇温缶２の昇温缶加熱部２ｅに導入する。ついで、この昇温缶加熱部２ｅに導入した留出アルコールベーパーで昇温缶２内の醪Ｂを間接加熱したのち、この留出アルコールベーパーを昇温缶加熱部２ｅからベーパー送給管１７により取り出して冷却器７に導入し、この冷却器７で冷却，液化して製品アルコール（約９００リットル，ＡＬＣ４０ｖｏｌ％）として取り出す。   First, 醪 A (2250 liters, an atmospheric distillation can 1 containing an alcohol concentration of 16 vol% was heated by a heating means, and distilled alcohol vapor (temperature 90 to 100 ° C.) vaporized and generated in the atmospheric distillation can 1 by this heating. ) Is introduced into the temperature riser heating part 2e of the temperature riser 2 containing the bowl B (1500 liters, alcohol concentration 16 vol%) through the vapor guide tube 14. Next, the temperature riser heating part 2e is introduced. After indirectly heating the soot B in the temperature rising can 2 with the distilled alcohol vapor, the distilled alcohol vapor is taken out from the temperature rising can heating portion 2e through the vapor feed pipe 17 and introduced into the cooler 7, and this cooling is performed. It cools and liquefies with the apparatus 7, and takes out as product alcohol (about 900 liters, ALC40vol%).

また、上記留出アルコールベーパーの加熱により昇温缶２内で気化生成した留出アルコールベーパー（温度６０℃）を導入管１８を介して、醪Ｃ（１０００リットル，アルコール濃度１６ｖｏｌ％）を収容した減圧蒸留缶３の醪Ｃ中に直接導入する。つぎに、この導入した留出アルコールベーパーで減圧蒸留缶３内の醪Ｃを昇温させ、この昇温により減圧蒸留缶３内で気化生成した留出アルコールベーパー（温度４５℃）を凝縮器４に導入して凝縮，液化し、その留出液を製品アルコール（約６００リットル，ＡＬＣ６６ｖｏｌ％）として取り出す。   Moreover, the distilled alcohol vapor (temperature 60 degreeC) vaporized and produced in the temperature rising can 2 by the heating of the said distilled alcohol vapor was accommodated through the introducing pipe 18 in the soot C (1000 liters, alcohol concentration 16 vol%). It introduce | transduces directly in the basket C of the vacuum distillation can 3. Next, the soot C in the vacuum distillation can 3 is heated by the introduced distilled alcohol vapor, and the distilled alcohol vapor (temperature 45 ° C.) vaporized and generated in the vacuum distillation can 3 by this temperature rise is added to the condenser 4. The product is condensed and liquefied, and the distillate is taken out as product alcohol (about 600 liters, ALC 66 vol%).

つぎに（すなわち、製品アルコールが得られたのち）、開閉弁１０ａを閉じ、常圧蒸留缶１内の蒸留廃液を取出管１５から抜き取り、新たに醪Ａを醪供給管１１から供給し、昇温缶２内の蒸留廃液を取出管１９から抜き取り、新たに醪Ｂを醪供給管１６から供給し、減圧蒸留缶３内の蒸留廃液を取出管２３から抜き取り、新たに醪Ｃを主原料供給管２１から供給する。このような操作を繰り返し、所望量の製品アルコールを得るようにしている。   Next (that is, after the product alcohol is obtained), the on-off valve 10a is closed, the distillation waste liquid in the atmospheric distillation can 1 is taken out from the take-out pipe 15, and the soot A is newly supplied from the soot supply pipe 11, Distillation waste liquid in the warm can 2 is extracted from the discharge pipe 19 and fresh soot B is supplied from the soot supply pipe 16, and the distillation waste liquid in the vacuum distillation can 3 is extracted from the take-out pipe 23 and newly supplied to the main raw material. Supply from tube 21. Such operations are repeated to obtain a desired amount of product alcohol.

このように、常圧蒸留缶１に醪Ａ（２２５０リットル）を、昇温缶２に醪Ｂ（１５００リットル）を、減圧蒸留缶３に醪Ｃ（１０００リットル）をそれぞれ収容し、所定量のスチームを用いて常圧蒸留缶１内の醪Ａを常圧蒸留することで、昇温缶２内の醪Ｂおよび減圧蒸留缶３内の醪Ｃを蒸留することができるため、常圧蒸留缶１で醪Ａを常圧蒸留するのに必要なスチームで、合計４７５０（２２５０＋１５００＋１０００）リットルの醪Ａ〜Ｃを蒸留することができ、スチームの使用量が従来の蒸留装置の１／２以下になる。   Thus, the atmospheric distillation can 1 contains 醪 A (2250 liters), the temperature rising can 2 contains 醪 B (1500 liters), and the vacuum distillation can 3 contains 醪 C (1000 liters). Since the soot B in the temperature rising can 2 and the soot C in the vacuum distillation can 3 can be distilled by subjecting the soot A in the atmospheric distillation can 1 to atmospheric distillation using steam, the normal pressure still can The steam required for atmospheric distillation of 醪 A at 1 can be used to distill a total of 4750 (2250 + 1500 + 1000) liters of 醪 A to C, and the amount of steam used is less than 1/2 of the conventional distillation apparatus. .

上記のように、この実施の形態では、スチームの使用量が従来の蒸留装置の１／２以下になる。しかも、昇温缶２内で気化生成した留出アルコールベーパーを減圧蒸留缶３に導入しているため、減圧蒸留缶３内の醪Ｃのアルコール度数を高めて、得られる製品アルコールのアルコール度数を高くすることができる。さらに、常圧蒸留と減圧蒸留との双方により製品アルコールを得ることができ、製造量がアップする。そのうえ、常圧蒸留缶１にコンデンサを必要としないため、ランニングコストが安価になる。このように、大幅な省エネルギー化を図りながらも、得られる製品の製造量をアップさせることができ、製造コストを下げることができる。   As described above, in this embodiment, the amount of steam used is ½ or less of the conventional distillation apparatus. Moreover, since the distilled alcohol vapor vaporized and generated in the temperature rising can 2 is introduced into the vacuum distillation can 3, the alcohol content of 醪 C in the vacuum distillation can 3 is increased, and the alcohol content of the product alcohol obtained is increased. Can be high. Furthermore, product alcohol can be obtained by both atmospheric distillation and vacuum distillation, and the production amount is increased. In addition, since the condenser is not required for the atmospheric distillation can 1, the running cost is reduced. In this way, the production amount of the obtained product can be increased and the production cost can be lowered while achieving significant energy saving.

なお、上記実施の形態では、常圧蒸留缶１での加熱は直接加熱および間接加熱の双方により行っているが、いずれか一方だけで行ってもよい。また、昇温缶２での加熱は間接加熱により行っているが、直接加熱および間接加熱の双方で行ってもよい。   In the above-described embodiment, heating in the atmospheric distillation can 1 is performed by both direct heating and indirect heating, but may be performed by only one of them. Moreover, although heating with the temperature rising can 2 is performed by indirect heating, it may be performed by both direct heating and indirect heating.

また、上記記醪Ａ，Ｂ，Ｃの原料としては、米，麦，さつま芋，そば等の各種の主原料や、コーンスターチ，タピオカスターチ，その他のスターチもしくは穀物等の各種の副原料が用いられる。また、上記実施の形態では、上記醪Ａ，Ｂ，Ｃとして、別種のものを用いているが、同種のものを用いてもよい。   In addition, as raw materials for the above-mentioned rice cakes A, B, and C, various main raw materials such as rice, wheat, sweet potato and buckwheat, and various auxiliary raw materials such as corn starch, tapioca starch, and other starches or grains are used. Moreover, in the said embodiment, although the different kind is used as said ridges A, B, and C, you may use the same kind.
