Intensification of process of separation of grain

Problems of postharvest processing of grain material are considered. The perspective directions of line postharvest processing of grain are presented. The perspective directions coordinating and balancing the main components of processes of line postharvest processing of grain are use of an air stream and heating of air at a stage of reception and temporary placement of grain, combination of several technological operations in modules of reception, drying and cleaning offices. It is necessary to provide automated management and the specialized modes of a side job at the expense of a block and modular design of grain cars with advanced system of distribution of agents of drying, heating and aeration that will give the chance of substantial increase of efficiency of the subsequent technological processes of postharvest processing and processing of grain. One of ways of an intensification of process of separation of grain on flat sieves is offered. The useful model belongs to agricultural mechanical engineering, in particular to the cars making primary cleaning of grain lots and can be used on the grain currents and the enterprises which are engaged in cleaning and processing of grain, Pancake week, bean and other types of the cultures needing preliminary and primary purification of material. The Reshetny camp including a flat sorting sieve it is executed with the oblong openings located at an angle to a longitudinal axis of a sorting sieve, the case of a sieve, the brush cleaner fixed on a dual infinite chain, the chain asterisks which are rigidly fixed on the leader to a shaft hinged drafts, one end from which it is fixed on the sieve case.
