Abstract. There were analyzed the components of power consumption during an implementation of technological processes of after-harvesting grain processing under conditions of Siberia. Electric power inputs for producing agricultural products in Russia are 1.5-3 times higher than those in the developed countries of Western Europe. Two kinds of energy are mainly used: electric power, then transformed into mechanical work, and heat, which is used for drying and short-term storage with the active ventilation by heated air. The classification of energy resources influencing the effectiveness of grain processing was carried out. They include direct, indirect and investment expenses as well as living-labor power. The effectiveness of after-harvesting grain processing can be considerably improved by better use of energy resources in the very technological process of cleaning and drying and by optimization of its parameters. When cleaning dry grain (with moisture content up to 16 %) from impurities at the grain cleaning and drying machine KZS-40Sh, the energy consumption was 200-350 MJ/t at the initial infestation of 15 %. The raising of the moisture content of the grain heap by 2 % increases energy consumption for its processing twice (from 300 to 600 MJ/t). Energy costs for seed grain processing are 3-4 times higher than for food grain.
Keywords: technological effect, post-harvest processing, grain, energy consumption, cleaning, drying, power capacity.
