METHOD FOR PRODUCTION OF ETHYL ALCOHOL FROM GRAIN RAW MATERIAL Russian patent published in 2012 - IPC C12P7/06 

FIELD: food industry.

SUBSTANCE: ethyl alcohol production method envisages peeling grains to produce a peel fraction in an amount of 2-5% wt of the total weight of grains and a fraction containing endosperm, mixing the fraction containing endosperm with water at hydraulic module equal to 1:(3.5-4.0), introduction of amylolytic enzymic preparations of diluent and saccharifying action in an amount of 0.5-1.0 "АС" units and 2.0-3.0 "ГлС" units per 1 g of conventional starch, the mixture dispersion in a rotary-pulsation apparatus at treatment rate equal to 1.5-3.0*10³ rpm during 5-10 minutes at a temperature of 56-58°C to produce the batch, the batch treatment at 56-58°C during 2-2.5 hours to produce saccharified wort, its cooling, brew fermentation and distillation to produce ethyl alcohol.

EFFECT: invention allows to reduce enzymic preparations consumption and decrease duration of water-and-heat and enzyme treatment.
