Abstract
The market value of alcohol production reaches 500 rubles per 1 decaliter (at a cost of up to 430 rubles per 1 decaliter), which does not allow it to be used effectively for purposes other than alcohol beverages. To successfully implement this ethanoll for the needs of the chemical and fuel industry it is necessary to achieve a market value of up to 300 rubles per 1 decaliter (with a cost of 250 rubles per 1 decaliter). To achieve such indicators, studies were carried out on the production of alcohol from starch-containing secondary raw materials of grain complex processing for gluten, starch, syrups, amino acids and organic acids. Samples of starch milk and wheat bran were used as secondary raw materials. As a result, the ratio of starch milk and bran was selected, which allows obtaining a normative yield of alcohol up to 66.3 decaliter / ton of conventional starch. The resulting bard was similar in terms of indicators from the grain, which makes it possible to treat stillage to dried fodder using the same enrgysave equipment. To increase the value of this food, it was enriched with protein by cultivation of fodder yeast. As a result, a fodder product was obtained, corresponding to GOST R 55301-2012 "Yeast fodder from a cereal bard". Based on the conducted studies, a technology was developed for processing a mixture of starch milk and bran in ethyl alcohol and a protein feed product. The technical and economic analysis of the developed technology demonstrates efficiency of secondary raw material using for production of ethyl alcohol and protein fodder.
