The results showed that the addition of 10 U/g cellulase in the residual distiller′s grains could effectively increase the content of reducing sugar after 5 h water bathing in water bathing pot at 58 ℃, the alcoholicity by the fermentation of the residual distiller′s grains could reach 4.67 %vol, and liquor yield could reach 31.39 %(increasing by 2.61 % than untreated distiller′s grains).

结果表明，在残糟中添加纤维素酶10 U/g，于58 ℃的水浴锅中保持5 h，可以提高还原糖的含量，残糟发酵酒精度达到4.67 %vol，出酒率达到31.39 %，出酒率比原糟提高了2.61 %，蒸馏出的产品达到蒸馏白酒各项卫生指标，达到优质酱香白酒的要求，提高了酱香型白酒酒糟的利用价值。

This equipment is mainly composed of steam still, alcohol content-adjusting pot without last distillate, air exhausting pipes, cooler and filtering system ( there are filtering material handled in special way inside), automatic temperature control and instrument display, which can make alcohol content reach 10°-89 °, there is no last distillate, the alcohol produced by this equipment is like mineral water, pure, without different taste or foreign matter but with splendid quality, and this equipment produces spirits faster as spirits can be produced in half an hour and 200 jin grains can be distilled in about 2 hours, which save half of the fuel compared with traditional technique; and its characters also include air distillation, no explosion, long service life, and easily being cleared and removed.

该设备主体由蒸汽蒸馏釜、无酒尾酒度可调锅、导气管和冷却器及过滤系统(内有经特殊处理过的过滤材料)、自动控温、仪表显示，可使酒度在10—89度间调节，没有酒尾，所产的酒清澈如矿泉水，口味纯正，无邪无杂，品质超群，该设备出酒快，只需半小时左右有酒出200斤粮食需2小时左右即可蒸馏完毕，比传统工艺节约燃料50％；常压蒸馏、无爆现象，使用寿命长易清洗易搬动。
