Mathematical model of the technological process of fractional grain cleaning under conditions

The productivity of grain cleaning units on which grain processing is implemented is limited by the capacity of oat cylinders. The use offractional purification technology, where a part of the grain (its fine fraction with light admixture) is processed in oat cylinders, will provide an increase in the productivity of the production line, which is economically viable. For effective separation and cleaning of grain under conditions, a paddle grain feeder is proposed, which ensures a preliminary separation of the portion of the processed material. By analyzing the given qualitative indices of the technological process of fractional grain cleaning, the technology of processing grain material is substantiated. It is established that if the initial grain is contaminated with Tatar buckwheat up to 0.5%, its fine fraction is processed in oat cylinders, more than 0.5% in oat and cockle cylinders. The application of this technology provides an increase in the productivity of the production line and a decrease in the unit cost ofprocessing grain.
