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, milling the fraction containing endosperm, mixing the milled fraction containing endosperm with water, its three-stage water-and-heat treatment and enzymic hydrolysis, fermentation, fermented brew distillation to produce ethyl alcohol; milling is performed according to a closed circuit scheme envisaging passing the fraction containing endosperm through a hammer crusher with subsequent straining through a 1 mm diameter cell sieve to produce the through-product and the overtail; then the through-product is directed for mixing with water while the overtail is mixed with a new portion of the fraction containing endosperm and undergoes recrushing; the process of milling and purifying is repeatedly performed till formation of 100% through-product through of the total of the initial fraction containing endosperm a 1 mm diameter cell sieve. ^ EFFECT: invention allows to simplify the method for production of ethyl alcohol combined with preservation of its high quality characteristics and intensify the fermentation process. ^ 3 ex |
