摘要：
FIELD: heating, drying.SUBSTANCE: invention relates to automation of technological processes of drying and storage of crops, especially oil-bearing-crops. The method comprises drying oscillating in the temperature regime of plant materials in gravitationally moving layer of shaft dryer consisting of alternating in series zones of heating and cooling processing of raw materials with antioxidant and feeding it to the silo storage with periodic active ventilation supply of exhaust air after heating zones for preheating of plant materials the discharge of the resulting steam-air mixture of the exhaust air after zones of cooling, preheating of plant materials and active ventilation in a cyclone for removal of suspended particulate matter comprised in it, followed by cooling and dehumidifying in the evaporator and heating first in the condenser of the heat pump and then in the heater feeding of the prepared in a heat pump conditioned air to the zones of heating and cooling to form a closed loop, and stabilization of hydrothermal characteristics of the raw materials during drying and storage with impact on the flow rate, temperature and moisture content of the conditioned air supplied to the zones of heating and cooling of the dryer, and the flow rate of antioxidant depending on the flow rate of the dried plant raw material the novelty is the fact that after each heating zone mixing of plant raw material with an antioxidant is carried out, and for obtaining conditioned air the steam ejector heat pump is used, comprising a steam generator with electric heating elements and the safety valve, the ejector, the evaporator, the cold-receiver, the heat-exchanger-wasteheat exchanger, the condenser, the thermal expansion valve, the condensate collector working in a closed thermodynamic cycle in the cold-receiver of the steam ejector heat pump the steam-air mixture is cooled to the dew point temperature and its dehumidification is carried out by condensation of moisture contained in
