ETHYL ALCOHOL PRODUCTION METHOD Russian patent published in 2011 - IPC C12P7/06 

FIELD: food industry.

SUBSTANCE: method envisages grains purification from metal and adventitious impurities with their subsequent washing with cold water and separating impurities from the grains mass; the separated impurities differ from the grains mass in hydrodynamic properties. Then the grains are disinfected during 10-15 minutes at a temperature of 15-20°C in a vessel for ozonation by way of supplying ozonised water into it. The grains are soaked till moisture content is 37-39%, then one precedes with hydromilling and subsequent kneading using enzyme preparations of α-amylase and glucoamylase, then one precedes with water-and-heat and enzyme treatment of grains at a temperature of 60-62°C during approximately 3 hours while the produced wort is fermented at a temperature of 28-30°C during 60-66 hours.

EFFECT: method allows to reduce consumption of heat and cooling water.
