Research on the obtaining of distillates from fermented grain and fruit raw materials using periodic devices

The work provides data on the technology for producing distillates during the joint processing of fruit and grain raw materials, using batch devices and continuous distillation units. Factors constraining the production of fruit distillates in the Russian Federation are considered. A method for processing fruit raw materials using existing equipment of distilleries is proposed. Using a laboratory batch distillation unit, the technological process for the industrial production of distillates using continuous distillation units was simulated. The features of the production of distillates from grain and fruit raw materials in a laboratory batch distillation unit using the double distillation method are considered. Based on the results of the studies, it was established that there is a technological possibility of using continuous-action devices, implemented on the basis of distillation units of distilleries, to obtain distillates with original organoleptic characteristics based on grain and fruit raw materials. Samples of unaged distillate with organoleptic characteristics inherent in the original raw material were obtained. A hardware and technological scheme for a continuous operation installation for the production of distillates from fermented grain and fruit raw materials has been developed. It has been revealed that the process of distillation of grain-fruit mash on devices operating under atmospheric pressure may be accompanied by the formation of carbon deposits of undissolved substances on the structural elements of the distillation apparatus. In the process of distilling mash from grain and fruit raw materials, the methyl alcohol content in the product can reach 0.2%, which must be taken into account when planning production. Recommendations have been developed for the implementation of the technological process for the production of distillates from grain and fruit raw materials on the technological equipment of alcohol factories.
