超贮稻谷生产燃料乙醇工艺进展及思考

近年来国内稻谷燃料乙醇技术发展较快，产量已达近百万吨。利用超贮稻谷发酵生产燃料乙醇既可以消纳不断上涨的稻谷库存，有效控制陈化粮食流入粮食加工市场，也可扩大燃料乙醇产业的原料来源。该文深入分析了稻谷组成特性及现有超贮稻谷燃料乙醇生产工艺的特点，剖析其中存在的问题，并提出改进的措施与建议，以期为我国超贮稻谷生产燃料乙醇产业发展提供参考。

Progress and reflection of fuel ethanol production process by over-storage rice

In recent years,the rice fuel ethanol technology has developed rapidly in China and the total yield of rice fuel ethanol was nearly one million tons.Using over-storage rice fermentation to produce fuel ethanol can not only consume large stock of rice,effectively control the flow of aged grain into grain processing market,but also expand the raw materials supply source for fuel ethanol industry.In this paper,the characteristics of material composition and present over-storage rice fuel ethanol production process were deeply discussed,the existing problems were analyzed,and some improvement measures and suggestions were proposed to provide a reference for the industry development of fuel ethanol produced by over-storage rice in China.
