| description | In the context of market economy, an urgent task of the alcohol industry is reducing the cost of commercial products by creating and introducing innovative energy-efficient and resource-saving technologies. In this aspect, a task of current importance is developing a technology that involves using new high-yielding races of distiller’s yeast to ferment highly concentrated wort obtained from grain raw materials. The wort used for fermentation was from different types of grain raw materials: maize, rye, wheat. The studies have shown that an increase in the concentration of dry matter of maize wort (up to 30%) makes it possible to obtain wash with the alcohol concentration 15.65% vol., an increase in the dry mater concentration of wheat wort (up to 27%) – 14.10% vol., in that of rye wort (up to 24%) – 13.00% vol. ethanol. With the standard yield of alcohol from 1 tonne of standard starch, the maximum alcohol content in the maize wash was 14.91% vol., while in the wheat wash, it was 14.1% vol., and in the rye wash, 13.0% vol. It has been studied how the temperature of fermentation of high-concentration wort affects the chemical and technological parameters of fermented maize wash. It has been established that the stage-by-stage fermentation of maize grain wort (at 35 and 30°С) creates conditions for additional saccharification of dextrins in the wort and for its effective end-fermentation. Therefore, this technique is especially effective in the fermentation of high-concentration wort. The introduction of the technology developed will allow efficiently processing agricultural raw materials into alcohol and reducing production waste (post-alcohol stillage). To validate the results of the theoretical and laboratory studies, the technology of highly concentrated alcohol wash from grain raw materials has been tested in the conditions of alcohol production at the company TOV FAZOR in Kozhanka, Fastiv District, Kyiv Region (capacity 6000 dal of alcohol-containing liquids a day). For the manufacturing tests, technological guidelines were developed and approved according to the due procedure. |
