Theoretical researches of the technological process of pneumoviral separation of grain mixtures on the pneumatic flow center separators of new generation grains, aimed at increasing the efficiency and quality of the phased separation of grain mixtures. The analysis of the results of the well-known studies presented in the scientific and technical literature on the issues of pneumatic and centrifugal and pneumatic separation of grain mixtures was carried out by analytical and deductive methods, on the basis of which the parameters of the investigated operations of the technological process of the motion of the grain mixture in the pneumoviral separating device were substantiated by theoretical methods. The theoretical researches of the technological process of pneumoviral separation of grain mixtures have been made, which makes it possible to determine the structuralkinematic and technological parameters of the grain-cleaning air-solenoid pneumatic-centrifugal unit with productivity from 25-50 t / h on primary purification of wheat grain with the provision of qualitative indicators in accordance with DSTU 3768: 2010 and seed quality of seeds respectively РН-1-3 ДСТУ 2240-93 at productivity from 10-20 t / h. It is established that the application of the process of pneumatic separation of cereal mixtures when used in the construction of a pneumatic centrifugal separator has the potential to increase its productivity by 1,5-2 times compared with the performance of known industrial separators and on its basis create a new generation of universal centrifugal centrifugal separators with productivity of 50, 100 and 200 t / h.
