Abstract

Energy costs of grain drying account for about 30% of the total energy consumption of the processes of grain production. It is possible to reduce the energy consumption of drying with the use of a microwave field. In such case, it is necessary to develop such design of the microwave-convective zone which could ensure the uniformity of grain drying throughout the whole volume of grain. For this purpose, it is expedient to carry out the simulation of the process. The developed computer model of heat and moisture exchange in the grain layer allows for modeling with varying parameters of the grain layer and the drying agent. Besides, the model considers characteristics of microwave field density change in the drying zone depending on the grain moisture content and distance from magnetron. The paper presents the results of modeling of grain drying with two variants of air distribution in the microwave-convective zone.
