Distillery residue of spirituous liquor Shochu contained many nutrients for livestock and is expected to be used as a feedstuff. However, difficulty of the preservation of this distillery residue prevents to use it as a feedstuff. To solve this problem, we first separate the solid part of this material by disk-separator and we condensed the liquid part by a multiple effect evaporator. The dry matter content of the solid part is about 30% and thus easy to be dried. The dry matter content of the condensed liquid portion is about 15% and can be stored long because of its high concentration of citric acid and low pH. Because of the fluidity of the condensed liquid, it is difficult to condense further. However, fluidity can be improved by adding yellow grease and by the treatments with enzymes such as cellulase, amylase etc. Some mixed treatments by these methods may be more effective to improve the fluidity.
