Mathematical model warm and moisture exchange in an elementary layer when drying grain active aeration

The article attempts to describe the process of exchange of heat and moisture in the elementary layer in drying grain active ventilation. A technique for calculating the stepwise process of drying grain in the dense layer. Applying the approach of using Laplace transforms to solve the equations of the exchange of heat and moisture in the grain layer to obtain the transfer functions describing the dynamic properties of the drying process. The mathematical model of drying in an elementary layer of grain is constructed.
