FIELD: drying of loose agricultural products, predominantly grains and seeds. SUBSTANCE: process consists in preliminary heating and drying of seeds in chamber of gravitational movement of dense layer under temperature of heat transfer agent equal to 65-75 C and in subsequent drying of seeds in alternating fluidized and incident layer moved along trajectory approaching sinusoid with direct extreme sections. Trajectory of movement is chosen so that while layer transfers from fluidized state to incident one and vice versa layer of product is turned over. In sections of incident layer product is blown through in transverse direction and in sections of fluidized layer transporting flow of heat transfer agent is brought into product with uniform distribution of it over surface of layer. EFFECT: enhanced quality of dried product and intensified drying process. 3 cl, 1 dwg
