Storing grain quality materials in post harvest handling and storage is largely dependent on correctly implemented the drying process. In agricultural production mainly use costly convection dryer. The main share of wasteful energy consumption accounts for heat drying agent, some heat is lost to the environment through the working surface of the dryers and spent coolant. Ways to reduce these energy costs is to reduce the amount of drying agent in the process to the level necessary to absorb and remove moisture from the dryer and the working volume of the principles of targeted "delivery" of energy to vysushuyemoho material. Last principles successfully implemented using contactless energy supply of electromagnetic fields in a material exposure by microwave or infrared radiation. The article deals with the theoretical background processes of drying material in cyclic mode with infrared heating and high frequency electromagnetic field. The equations change over time settings grain material by heating using high frequency electromagnetic field or infrared light and ventilation in the grain does not allow heated air drying cycle count process. The algorithm calculating the overall process of drying cycle to determine rational modes of the process, providing minimize energy costs.
