Study on the Fermentation of Uncooked Corn Flour to Produce Alcohol

In order to study the fermentation of uncooked corn flour to produce alcohol, 100L fermenting pot test was carried out and the experimental conditions were as follows: granule size(30 mesh, 100 % pass rate), 0.02 % yeast used, the use level of GC626 and FERMGEN and STARGEN002 were 0.15 g and 0.10g and 2.0 g respectively per kg corn flour, liquefaction time was 2 h, the ratio of raw materials and water was1∶2.35, fermenting temperature was at 32 ℃, stirring speed was 100 r/min, and fermenting time was 80~90 h. The experimental results showed that the fermentation of uncooked corn flour to produce alcohol was feasible and it could save energy consumption in practice.
