Abstract. The paper emphasizes that at present one of the tasks of the country's development is to increase grain production based on a significant increase in yield and reduce losses at all stages of its processing. During the period of harvesting and post-harvest processing, agro-climatic conditions are in most cases unfavorable, therefore, in the system of technological operations and post-harvest processing of seeds and grain, an important place belongs to their drying. In the article, the mathematical description of the grain drying process is based on a mathematical model in which the heat fluxes in the layer due to thermal conductivity were neglected, and shrinkage and pressure gradient were not taken into account. The zonal calculation method is considered, in which these characteristics are assumed to be constant.
