固定化酵母流化床生物反应器生产酒精工业性系统的设计

Design for the Ethanol Production System with Fixed-yeast Biological Reactor

本文公布了为“中国东北寒冷地区能源示范基地”设计的３种原料生产酒糟的固定化酵母工艺流程及其设备．通过生产性试运转到得，含糖１１％的发酵液经固定化酵母发酵后酒精含量为７％，酒精的转化率为５０％，达理论转化率的９３％，酒精产率为１７．７ｋｇ／ｍ３·ｈ，达到了设计要求．

This paper reports the fixed -yeast technological processes and equipment with three kinds of raw materials for the design of 'Energy Iwtegrated Demonatration Gase for China'sCold Northeastern Region '.The test-run results showed 7% ethanol was obtained after fermentation using 11% sugar fluid through fixed-yeast fermentation .The conversion rate of ethanol was 50% (93% of the theoretical value ). The ethanol prodction rate was 17.7kg/m3. h.
