Abstract

   The subject of the study is the process of active ventilation of wheat grain with variable heat supply.

   The purpose of the work is a mathematical description of the nature of the flows of matter and energy in the process of active ventilation of wheat grain.

   Thanks to the selected original design of the exhaust coolant outlet unit, made in the form of a mesh spiral tube, it was possible to optimize the hydrodynamic situation in the layer of dried grain. The developed mathematical model, as a mathematical description, consists of equations of material, thermal balances, equations of hydrodynamics in steady and unsteady states. This mathematical model is the basis for creating a material model of the process and conducting an experiment with subsequent data processing. As a result, it is possible to obtain criteria equations of processes that make it relatively easy to calculate processes under various technological modes.
