Modern science in the field of agriculture is actively looking for promising ways and technological equip-ment to destroy harmful microflora in feed grains before feeding farm animals, which, in turn, should increase the quality and nutritional value of feed. The technological process of processing feed grain, namely disinfection, imposes special requirements on the designs of devices for heat treatment of grain crops. Based on the analysis of well-known engineering solutions for the heat treatment of grain, a promising direction for the development of a device for the heat treatment of feed grain is substantiated [1-3].The work is aimed at improving the effi-ciency of disinfection by improving the technological process and design of the device for heat treatment of grain in feed production and is relevant for the agroindustrial complex of the Russian Federation.The article describes the design, the technological scheme of operation, the result of laboratory experiment of a new device for heat treatment of grain in feed production. The application of the device can result in the improvement of the quality of preparation of feed grain for processing, the increase of nutritional value of feed grain and the degree of uniform disinfection of the dried crop, which minimizes the need for a separate procedure aimed at stopping the microflora.
Keywords: heat treatment, infrared radiation source, micronizer, feed grain, feed, quality, nutritional value, technological process, microflora, hay bacillus.
