用陈化粮发酵生产燃料酒精的工艺

Study on Technology of Producing Fuel Alcohol by Fermenting Excess Rice

从糖化酶的用量、酵母菌株、酵母种的用量、培养温度、加水时间进行了陈化粮发酵生产燃料酒精工艺的研究。结果表明,糖化酶用量是0.300 g,选择1号酵母菌株,1号酵母种用量是0.5‰,发酵温度36℃,加水时间为24h,能获得较高的酒精产量。

The process to produce fuel alcohol by fermenting excess rice was studied in five aspects： the level of glucoamylase, the choice of leaven,the level of leaven, developed temperature, the time of adding water. The result showed that the best is fermented condition is 0.300g level of glucoamylase, the 0.5%v level of leaven No.1, developed temperature 36℃, the time of adding water 24h.
