FIELD: agriculture.
SUBSTANCE: method of active grain aeration consists in that the grain is loaded, exposed to the impact of heated and non-heated drying agent, and unloaded. According to the invention, the duration of exposure to heated and non-heated drying agent is defined by formulas depending on the R - caryopsis radius, ϕp - relative vapour moisture on the caryopsis surface, ϕ1, ϕ2 - relative moisture content of the heated drying agent on the inlet and outlet of the layer, ϕ'1, ϕ'2 - relative moisture content of the non-heated drying agent on the inlet and outlet of the layer, β, β' - the mass transfer factor for the heated and non-heated drying agent.
EFFECT: invention must provide safe oscillating grain drying by active ventilation.
