Abstract
The main directions of research concerning post-harvest grain processing have been established: the first category includes cleaning methods, the second separator design, and the third grain cleaning technology. The most frequently used cleaning methods are highlighted. It is established that modern machines for primary grain processing use two-channel aspiration systems and three sieves in one tier of the sieve mill. The differences and advantages of air-sieve machines are shown. The low efficiency of pneumatic separators as independent devices for grain cleaning is shown: when feeding grain material of 7.9 t/h, the purity of the material when using the PS-15 separator increased from 98.16% to 98.70%; when feeding 9.6 t/h from 98.02% to 99.03%; when feeding 13.4 t/h from 97.73% to 98.04%; when feeding 14.9 t/h from 98.12% to 98.77%; when feeding 16.0 t/h from 97.55% to 98.29%. The efficiency of energy-saving gravity separators ZG-5 is shown: the content of the weed impurity when using it decreased to 0.67...0.98%, grain impurity up to 0.87...1.25%. The main objectives of various grain cleaning equipment are outlined: basic cleaning, isolation of difficult-to-separate impurities, obtaining high-quality seeds, energy saving. Two main new technologies of grain purification are given: fractionation and differentiation of grain heaps. Recommendations for developers of grain cleaning equipment are given.
