The mode of oscillating drying (MOD) of grain is most effective if temperature of grain is equal limited hot during all process. It is thus important to calculate correctly temperature of the agent of drying at the live and off furnace, length of heating and cooling down of grain. They evaluated optimum indicators of a MOD of grain at which the best economic efficiency is possible. For calculation of the listed parameters the simplified physical model of oscillating drying is considered. On the formulas received during researches authors have calculated length of heating and cooling down of grain, and also temperature of the agent of drying at the live and off furnace. Calculation of optimum parameters is used in practice when work of a grain dryer SZT-16 was adjusted on a MOD in a stream of wheat seeds and grains. The oscillating mode of drying was organized in the following manner. At symmetric 0.25 h cycles they lifted temperature of the agent until at the exit from the drying camera temperature of seeds reach 42-43 deg С, and grains – 46-47 deg С. This temperature was maintained during all process. The dried-up seeds and grain were cooled to 28-30 deg С and deleted from the dryer. On an entrance and an exit from the dry camera they evaluated humidity (14%) and temperature of seeds (43%) and grain (48%). At oscillating drying grain dryer performance is close to the classical one (temperature of the agent of drying is constant, 65 deg С for seeds and 85
deg С for grain), but fuel consumption decreases by 15%.
