【発明が解決しようとする課題】
しかしながら、本発明に関連する上述の従来技術は、以下に述べる問題を有している。即ち、特許文献1及び特許文献2に記載の製造方法は、水分含有率が95％と極めて高い焼酎粕を澱粉粕と混合して攪拌した後に気流乾燥させるため、その乾燥には多大なるエネルギーを要するという問題を有している。特許文献3に記載の製造方法は、前記特許文献1及び前記特許文献2に記載の澱粉粕に替えて乾燥ケーキを使用する濃縮工程を数回繰り返すことにより、得られる乾燥ケーキの粗蛋白質の含有率は向上するが、一方で、該濃縮工程における数回の加熱処理によって、多大なるエネルギーを消費すると共に、焼酎粕に含まれる成分が変性してしまうという問題を有している。
特許文献４に記載の製造方法は、焼酎蒸留廃液（焼酎蒸留残液）を加熱濃縮後、糠等を添加、混合、乾燥することを特徴とするが、当該製造方法における濃縮工程は、多大なるエネルギー（熱エネルギー）を必要とする物理的濃縮分離法の１つである加熱濃縮処理のみを介して行うものであることから、当該製造工程で発生する排ガスの熱を乾燥用熱源として再利用するものの、エネルギー消費が増大してしまうという問題を有している。
特許文献5に記載の製造方法は、焼酎粕を液体分と固体分に分離し、該液体分のSSを100(g/L)以下に調整する工程を有することから、熱交換が効率的に行われることが記載されている。しかしながら、特許文献5の該製造方法においては、該液体分と該固体分をそれぞれ別々に乾燥させる工程を有するために多大なるエネルギー（熱エネルギー）を必要としてしまうという問題を有している。
このように、従来の焼酎粕から得られる飼料の製造方法が有する上述した問題は早急に解決を要すべきものである。
【０００５】
本発明は、上述した知見に基づいて更なる研究の結果完成に至ったものであり、本発明の目的は、従来の焼酎粕からの飼料製造に係る上記問題点を解決し、優れたエネルギー効率の下に、利用性、嗜好性及び栄養性に優れた飼料の製造方法を提供することにある。

【０００７】
詳細には、上記目的を達成する本発明の大麦焼酎蒸留残液から得られる飼料の製造方法の骨子は、大麦焼酎製造において副生する大麦焼酎蒸留残液を固液分離して発酵残渣含有画分及び発酵残渣非含有画分を得る工程、該発酵残渣非含有画分を固液分離してケーキ分と液体分を得る工程、該液体分を濃縮処理に付すことにより濃縮液を得る工程、該発酵残渣含有画分、該ケーキ分、該濃縮液、及び糠のそれぞれを混合して気流乾燥機を使用する乾燥処理に付すことにより乾燥物を得る工程を含むことを特徴とする。
【０００８】
さらに詳細には、本発明の大麦焼酎蒸留残液から得られる飼料の製造方法は、大麦焼酎製造において副生する大麦焼酎蒸留残液を固液分離して発酵残渣含有画分及び発酵残渣非含有画分を得る工程、該発酵残渣非含有画分を固液分離してケーキ分と液体分を得る工程、該液体分を濃縮処理に付すことにより濃縮液を得る工程、該発酵残渣含有画分、該ケーキ分、該濃縮液、及び糠を、それぞれ10乃至25重量％、15乃至30重量％、30乃至50重量％、及び0乃至30重量％の割合で混合して気流乾燥機を使用する乾燥処理に付すことにより乾燥物を得る工程を含むことを特徴とする。
【０００９】
【実施態様例】
本発明において使用する大麦焼酎蒸留残液は、代表的には、大麦又は精白大麦を原料として大麦麹及び蒸麦を製造し、得られた大麦麹及び蒸麦中に含まれるでんぷんを該大麦麹の麹により糖化し、それらを酵母によるアルコール発酵に付して焼酎熟成もろみを得、得られた焼酎熟成もろみを減圧蒸留または常圧蒸留等の単式蒸留装置を用いて蒸留する際に蒸留残渣として副生するもの、即ち、大麦焼酎の蒸留残液を意味する。
【００１０】
本発明において、大麦焼酎製造において副生する大麦焼酎蒸留残液を固液分離して発酵残渣含有画分及び発酵残渣非含有画分を得る第1の工程は、大麦焼酎蒸留残液から、原料大麦あるいは大麦麹由来の水不溶性のSS分からなる発酵残渣を分離することを目的として行うものである。この第1の工程における当該固液分離は、スクリュープレス方式やローラープレス方式の固液分離機、或いはろ過圧搾式の固液分離機等を使用することができる。
【００１１】
第1の工程で得られた該発酵残渣非含有画分を固液分離してケーキ分と液体分を得る第2の工程は、機械的分離濃縮方法の一種であるデカンタ等の遠心分離機、或いはこれに類するものを使用することができる。
【００１２】
第2の工程で得られた該発酵残渣非含有画分の該液体分を濃縮処理に付すことにより濃縮液を得る第3の工程は、通常、該発酵残渣非含有画分の該液体分が有する90重量％程度の水分を、好ましくは40乃至60重量％まで濃縮することを目的として行うものである。この第3の工程における濃縮処理には、公知の方法を用いることができ、具体的には、多重式減圧濃縮装置、真空蒸発装置等を用いることができる。
【００１３】
第１の工程で得た前記発酵残渣含有画分、第2の工程で得た前記ケーキ分、及び第3の工程で得た前記濃縮液に、糠を混合して気流乾燥機を使用する乾燥処理に付すことにより乾燥物を得る第4の工程においては、該発酵残渣含有画分、該ケーキ分、該濃縮液、及び該糠を所定の割合で混合することが好ましい。具体的には、該発酵残渣含有画分、該ケーキ分、該濃縮液、及び該糠を、それぞれ10乃至25重量％、15乃至30重量％、30乃至50重量％、及び0乃至30重量％の割合で混合することが好ましい。糠としては、小麦糠、大麦糠、或いは米糠等を使用することができ、こうした糠の他に籾殻等も用いることができる。更に、気流乾燥機を使用する乾燥処理における熱風温度は、好ましくは75乃至120℃、より好ましくは85乃至95℃とする。なお、本発明においては、該気流乾燥機の他に、ロータリーキルンや真空乾燥機を使用して乾燥処理に付すこともできる。
【００１４】
このような本発明の飼料の製造方法を介して得られる家畜用飼料は、従来品と比較して粗蛋白含量が極めて高いことから、嗜好性及び栄養性に優れている。また、該家畜用飼料は、従来品と比較して極めて均一で微粒なる粉末形状を有することから、他の飼料原料と容易に混合することができ、配合飼料の原料の１つとしても使用することができる他、ペレット型飼料等のような成形加工を必要とする飼料の原料としても好適に使用することができる。
【００１５】
ところで、上述した特許文献４には、焼酎蒸留廃液（焼酎蒸留残液）を加熱濃縮後、糠等を添加、混合、乾燥することを特徴とする家畜用飼料の製造方法が記載されている。しかしながら、当該製造方法は焼酎蒸留残液を固液分離せずにそのまま濃縮工程に供することから、本発明とは明らかな差異を有している。即ち、特許文献４の製造方法における焼酎蒸留廃液をそのまま加熱濃縮する工程は、本発明における、焼酎蒸留残液を固液分離して発酵残渣含有画分及び発酵残渣非含有画分を得る工程、該発酵残渣非含有画分を固液分離してケーキ分と液体分を得る工程、及び該液体分を濃縮処理に付して濃縮液を得る工程とは明らかに別異なるものである。しかも、特許文献４の製造方法における濃縮工程は、多大なるエネルギーを必要とする物理的濃縮分離法の１つである加熱濃縮処理のみを介して行うものであるのに対して、本発明の製造方法が包含する、焼酎蒸留残液を固液分離して発酵残渣含有画分及び発酵残渣非含有画分を得る工程、及び該発酵残渣非含有画分を固液分離してケーキ分と液体分を得る工程は、いずれも前記物理的濃縮分離法ほどに多大なるエネルギーを要しない機械的濃縮分離法の１つである、スクリュープレス処理やデカンタ処理を介して行うものである。従って、特許文献４の製造方法よりも本発明の製造方法のほうが、焼酎蒸留残液（焼酎蒸留廃液）を濃縮乾燥して家畜用飼料を得るのに要するエネルギーは明らかに少ないものとなる。
【００１６】
上述した特許文献5には、焼酎粕を液体分と固体分に分離し、該液体分のSSを100(g/L)以下に調整後、該液体分と該固体分をそれぞれ別々に乾燥させ、その後、該液体分乾燥物および該固体分乾燥物を混合することを特徴とする焼酎粕から得られる飼料の製造方法が記載されている。そして、該特許文献5の製造方法における、焼酎粕を液体分と固体分に分離し、該液体分のSSを100(g/L)以下に調整する工程は、本発明における、焼酎蒸留残液を固液分離して発酵残渣含有画分及び発酵残渣非含有画分を得る工程と実質的に同一のものである。しかしながら、該特許文献5の製造方法には、本発明における、該発酵残渣非含有画分（特許文献5に記載の「液体分」に相当）を固液分離してケーキ分と液体分を得る工程、及び該液体分を濃縮処理に付して濃縮液を得る工程については全く記載されていない。しかも、該発酵残渣非含有画分を固液分離してケーキ分と液体分を得る工程は、前記物理的濃縮分離法ほどに多大なるエネルギーを要しない機械的濃縮分離法の１つであるデカンタ処理を介して行うものである。従って、特許文献5の製造方法よりも本発明の製造方法のほうが、機械的濃縮分離法を介した処理工程が多く、焼酎蒸留残液を濃縮乾燥して家畜用飼料を得るのに要するエネルギーは明らかに少ないものとなる。従って、本発明は、構成及び効果のいずれにおいても特許文献5の発明とは明らかに別異なるものである。
以上の通り、本発明の大麦焼酎蒸留残液から得られる飼料の製造方法は、上述した特許文献に記載された従来技術とは別異なる新規なものであることが判明した。

[Problems to be solved by the invention]
However, the above-described conventional technology related to the present invention has the following problems. That is, in the production methods described in Patent Document 1 and Patent Document 2, since a very high shochu liquor with a moisture content of 95% is mixed with starch cake and stirred and then air-dried, much energy is required for the drying. It has a problem of requiring. The production method described in Patent Document 3 includes the crude protein content of the resulting dried cake by repeating the concentration step using the dried cake several times instead of the starch cake described in Patent Document 1 and Patent Document 2. Although the rate is improved, on the other hand, there are problems that a large amount of energy is consumed and the components contained in the shochu are denatured by several heat treatments in the concentration step.
The production method described in Patent Document 4 is characterized in that after shochu-distilled waste liquid (shochu-distilled residue) is heated and concentrated, soot and the like are added, mixed, and dried, but the concentration step in the production method is enormous. Since it is performed only through the heat concentration process, which is one of the physical concentration and separation methods that require energy (thermal energy), the heat of the exhaust gas generated in the production process is reused as a heat source for drying. However, there is a problem that energy consumption increases.
The production method described in Patent Document 5 has a step of separating shochu into a liquid component and a solid component, and adjusting the SS of the liquid component to 100 (g / L) or less, so that heat exchange is efficiently performed. It is described that it is done. However, the production method of Patent Document 5 has a problem that a large amount of energy (thermal energy) is required because the liquid component and the solid component are separately dried.
As described above, the above-mentioned problems of the conventional method for producing feed obtained from shochu should be solved immediately.

Moreover, since the livestock feed has a powder shape that is extremely uniform and finer than the conventional product, it can be easily mixed with other feed raw materials, and is also used as one of the raw materials for blended feeds. In addition, it can be suitably used as a raw material for feeds that require a molding process such as pellet-type feeds.

By the way, Patent Document 4 described above describes a method for producing livestock feed, characterized in that after shochu-distilled waste liquid (shochu-distilled residue) is heated and concentrated, straw or the like is added, mixed, and dried. However, the production method has a clear difference from the present invention because the shochu-distilled residue is directly subjected to the concentration step without solid-liquid separation. That is, the step of heating and concentrating the shochu-distilled waste liquid as it is in the production method of Patent Document 4 is a step of solid-liquid separating the shochu-distilled residue in the present invention to obtain a fermentation residue-containing fraction and a fermentation residue-free fraction, The step of solid-liquid separating the fermentation residue-free fraction to obtain a cake and a liquid and the step of subjecting the liquid to a concentration treatment to obtain a concentrate are clearly different. In addition, the concentration step in the manufacturing method of Patent Document 4 is performed only through the heat concentration process, which is one of physical concentration and separation methods that require a large amount of energy, whereas the manufacturing method of the present invention. The method includes a step of solid-liquid separation of shochu distillation residue to obtain a fermentation residue-containing fraction and a fermentation residue-free fraction, and solid-liquid separation of the fermentation residue-free fraction to obtain a cake fraction and a liquid fraction The process of obtaining is carried out via a screw press process or a decanter process, which is one of mechanical concentration / separation methods that do not require as much energy as the physical concentration / separation method. Therefore, the production method of the present invention requires significantly less energy to obtain livestock feed by concentrating and drying the shochu distillation residual liquid (shochu distillation waste liquid) than the production method of Patent Document 4.
[0016]
In Patent Document 5 described above, shochu is separated into a liquid component and a solid component, and after adjusting the SS of the liquid component to 100 (g / L) or less, the liquid component and the solid component are dried separately. Then, a method for producing a feed obtained from shochu characterized by mixing the dried liquid product and the dried solid product is described. Then, in the production method of Patent Document 5, the step of separating the shochu into a liquid component and a solid component and adjusting the SS of the liquid component to 100 (g / L) or less is the shochu distillation residual liquid in the present invention. Is substantially the same as the step of obtaining a fermentation residue-containing fraction and a fermentation residue-free fraction by solid-liquid separation. However, in the production method of Patent Document 5, the fraction containing no fermentation residue in the present invention (corresponding to the “liquid content” described in Patent Document 5) is subjected to solid-liquid separation to obtain a cake component and a liquid component. There is no description at all about the step and the step of subjecting the liquid to a concentration treatment to obtain a concentrate. In addition, the step of obtaining a cake and a liquid by solid-liquid separation of the fermentation residue-free fraction is one of mechanical concentration separation methods that do not require as much energy as the physical concentration separation method. This is done through processing. Therefore, the production method of the present invention has more processing steps through the mechanical concentration and separation method than the production method of Patent Document 5, and the energy required for concentrating and drying the shochu distillation residue to obtain livestock feed is Clearly less. Therefore, the present invention is clearly different from the invention of Patent Document 5 in both configuration and effect.
As mentioned above, it turned out that the manufacturing method of the feed obtained from the barley shochu distillation residual liquid of this invention is a novel thing different from the prior art described in the patent document mentioned above.
