“…In the process of conducting scientific experiments conducted research steam sterilization. We note that in the previously developed technology, cooking was more intensive due to high-temperature heating (150-180°C), drying occurred due to fast (30-50 seconds, 10-20 m/s) and high-temperature blowing (250-300°C) dried particles [8][9] . However, after further fine grinding, the achieved sterility was lost.…”

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.

“…One of the perspective methods for studying processes in traction drive is the use of mathematical modeling methods, for example, [2]. Especially effective is the use of computer models in the design stage, as in the early stages of a new electric locomotive design allows to get answers to many questions, not making complex and costly prototypes [3][4][5].…”

Summary. In this paper, the problems arising from the design of electric locomotives with asynchronous traction drive (with three-phase AC induction motors) are considered as including the debugging of control algorithms. The electrical circuit provides the individual (by axle) control of traction motors. This allows realizing the operational disconnection/connection of one or more axles in the automatic mode, with account of actual load. In perspective, the evaluation of locomotive's energy efficiency at the realization of various control algorithms must be obtained. Another objective is to research the dynamic processes in various modes of the electric locomotive operation (start and acceleration, traction regime, coasting movement, wheel-slide protection, etc).To solve these problems, a complex computer model based on the representation of AC traction drive as controlled electromechanical system, is developed in Part 1. The description of methods applied in modeling of traction drive elements (traction motors, power converters, control systems), as well as of mechanical part and of "wheel-rail" contact, is given. The control system provides the individual control of the traction motors. Part 2 of the paper focuses on the results of dynamic processes modeling in various modes of electric locomotive operation.ИССЛЕДОВАНИЕ РЕЖИМОВ РАБОТЫ АСИНХРОННОГО ТЯГОВОГО ПРИВОДА МЕТОДАМИ КОМПЬЮТЕРНОГО МОДЕЛИРОВАНИЯ ЧАСТЬ 1: ПОСТАНОВКА ЗАДАЧИ И КОМПЬЮТЕРНАЯ МОДЕЛЬ Аннотация. В настоящей статье, рассматриваются проблемы, возникающие при проектировании электровозов с асинхронным тяговым приводом (АТП), в том числе отладка алгоритмов управления. В электрической схеме предусмотрено индивидуальное (поосное) регулирование тяговых двигателей, что дает возможность оперативного отключения/подключения одной или нескольких осей в автоматическом режиме, с учетом реальной нагрузки. В перспективе, должна быть получена оценка энергетической эффективности электровоза при реализации различных алгоритмов управления. Другой целью исследования является изучение динамических процессов в различных режимах работы электровоза (трогание с места, тяга, выбег, подавление боксования и т.д.). Для решения указанных проблем, в части 1 разработана комплексная компьютерная модель, основанная на представлении АТП как управляемой электромеханической системы. Приводится описание методов, использованных при моделировании элементов тягового привода (тяговых двигателей, силовых преобразователей, систем управления), 126 P. Kolpachchyan, A.

В части 2 сосредоточены результаты моделирования динамических процессов в различных режимах работы электровоза.
