Abstract:
The article is devoted to the study of the sterilization of waste materials and animal feed meal. It was
revealed that at the last stage of waste processing of animal origin, as a result of fine grinding in the
crusher, feed meal of low biological value is obtained. As a result of research, a technology of multistage sterilization of raw materials has been developed with obtaining feed meal of animal origin
of high biological value due to cooking-sterilization (stage 1), drying-sterilization (stage 2), steam
sterilization (stage 3). As a result of the final sterilization, i.e. steam sterilization of feed meal from
animal waste revealed that when the temperature drops below 110 °C and sterility is not achieved
when the warm-up time is less than 25 minutes and when the temperature rises above 134 °C and
the warm-up time is more than 50 minutes, the degradation of the sterilized materials begins. It is
revealed that the total number of microbes in 1 g of flour is completely eliminated due to the use of
multistage sterilization technology.
