The main quantity of the produced ethyl alcohol is consumed by the food industry as a basis for the manufacture of alcoholic beverages, pharmaceuticals and other alcohol-containing products. In addition to food production, ethyl alcohol is widely used in medicine, perfumery, and other industries. The actual problem of alcohol production is finding ways to reduce the cost of raw materials and energy resources but still getting the world quality standard of alcohol. The best solution to the problem is to improve the technological schemes of rectification plants. For this, information was updated on modern schemes and methods for obtaining rectified alcohol. During the research, and information search was carried out in Russian and English language literary sources. A comparative analysis of books, manuals and articles on this topic was carried out, as well as the GOSTs requirements for rectification columns over the past few years were studied. The main components of rectification units were considered: contact devices (types of plate and packed devices) and rectification columns (applied pressure: atmospheric, vacuum, under a certain pressure; and their total number).Progressive schemes used in modern alcohol production in Russia and abroad (Ukraine, USA, France, Finland) were considered. Based on the received data, the following conclusions were formulated: the most effective types of contact devices are sieve and valve trays, among the packing there are Raschig rings, a promising type of columns is disc-type, the most popular scheme for the operation of a rectification plant is a combination of work under pressure and vacuum.

Triticale accounts for the biggest share in gross processing and state procurement of grain in Belarussian production of alcohol. The main difficulty in its processing is the formation of viscous technological fluids due to the presence of non-starch polysaccharides in its chemical composition. All measures taken to solve the problem come down to the selection of the efficient enzyme preparations, hydrolyzing grain polymers into low molecular weight compounds, which have the ability to be disposed by the yeast cells and form the ethyl alcohol. But grain own enzymes are not involved. It is possible to solve the problem by means of biological activation, which will activate grain enzyme systems and partially hydrolyze grain polymers into low molecular weight compounds. The article considers general and special technological parameters of six cultivars of triticale selected in the Republic of Belarus: Antos, Kastus, Dubrava, Run, Prometheus, Impulse. The authors determined that the most promising cultivars for bioactivation and food grade ethyl alcohol production are Antos and Dubrava. The authors explored the possibility of using hot soaking of triticale grain for the biological activation. They also showed the advantages of introduction of amaranth green mass in the amount of 8% during hot soaking for the reduction of grain microbiological contamination. They studied the changes in the technological properties of triticale cultivars Antos and Dubrava after the bioactivation with the green mass of amaranth. The authors determined that grain microbiological characteristics improved, the activity of grain enzymes increased, proportion of low molecular weight compounds in the chemical composition increased. They studied the processes taking place during wort and mash production from the bioactivated triticale grain. The authors showed that the processing of bioactivated triticale grain resulted in the production of wort with higher concentration of dry matter which allowed to increase the ethanol content in the mature mash produced from triticale cultivar Antos by 19.5% and from the triticale cultivar Dubrava by 29.3% and reduce the total quantity of the main impurities in distillates.

The manufacturing process, the source (raw materials), and primary packaging materials dictate requirements for the quality of ethyl alcohol used in the pharmaceutical industry.The aim of the paper was to analyse how the quality of ethyl alcohol used as a component of medicinal products depends on the starting materials, production method and technology, intended use, and the choice of the primary packaging. The paper analyses available information on ethyl alcohol quality and summarises data on potential impurities associated with the ethyl alcohol production technology and the starting materials used. It was established that Russian manufacturers mainly use grain crops (wheat and rye), as well as molasses—a by-product of the sugar industry, as raw materials. The paper addresses the process of improving the quality standards for ethyl alcohol from a historical perspective. A comparative study of the requirements of the Russian and the world’s leading pharmacopoeias for the pharmaceutical substance—ethyl alcohol 95%, 96% demonstrated the need to include identification by IR-spectrometry and impurity control by UV absorbance into the respective monograph of the State Pharmacopoeia of the Russian Federation. The authors formulated requirements for the choice of packaging material for ethyl alcohol, which will not affect its quality during transportation and storage.

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.
