EVALUATION OF GRAIN SHELLING EFFICIENCY BY ROTOR-TYPE MACHINES

Abstract

Grain processing for the purpose of manufacturing products and compound feed is one of the main directions of the country's economic development. The grain prepared for the production of products and compound feed must meet the requirements that make it necessary to obtain quality compound feed, groats, flour and other products. Grain processing is the most important component of the country's agricultural sector, as it provides the consumer market with the necessary raw material.The grain processing industry in the country reaches a significant volume and has prospects for development and increased productivity. The processing of wheat, which contains about 80% of endosperm, appears to be the most important and significant. The efficiency of technological processes of grain preparation in the production of compound feed, groats, flour and other products depends on energy consumption. One of the most important operations of grain preparation for processing is the process of its dehusking. The choice of a rational method for the most effective dehusking process, i.e. the separation of the grain sheaths from the core can be carried out based on taking into account the mechanical properties of the grain and the features of the adopted technological operations. Taking into account the characteristics of the destruction of strength, stresses and friction and properties of viscosity, microhardness and stress relaxation of anisotropic structural grain systems during the organization of the process with the establishment of minimum energy consumption for the implementation of the peeling process is of great practical importance. The optimal mode of control of the peeling process is connected with the choice of kinematics and dynamics of the working body of the machine.
