| Summary: | One of the important and crucial stages of post-harvest treatment of rapeseed is drying. The purpose of the article is to improve the drying process of seeds of small seed oil crops using electromagnetic radiation of the microwave range in order to increase its productivity and determine the optimal operating parameters. The article describes the construction of a new microwave (UHF) dryer with a capacity of 200 kg h-1 for drying small-seeded crops. Curves were obtained that show the dependence of the heating temperature of seeds on microwave power, the effect of initial seed moisture and heating temperature on drying kinetics. The ratio of the stages of microwave heating and cooling was determined, which allows to increase the drying efficiency.
