GRAIN DRYING DEVICE Russian patent published in 2022 - IPC F26B17/04 F26B3/20 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural machinery, in particular to devices for drying grain. The device for drying grain contains a casing, the surface of which is covered with a layer of insulating material, a transporting working body in the form of an endless chain with scrapers, a loading hopper, an unloading window, heating elements, a box installed inside the casing, as well as a cooling device consisting of a fan and an air duct is installed inside the casing. The box, except for its sides, is made of heat-conducting material and is oval in the longitudinal vertical plane. The inner surface of the casing follows the contours of the box, and the distance from the inner surface of the casing to the outer surface of the box is constant and equal to the height of the scrapers of the transporting working body, which is equal to the maximum grain size. The heating elements are installed on the inner surface of the box. The air duct of the cooling device is installed on the side of the casing. The casing wall located opposite to the duct is perforated. The discharge window is located at the bottom of the casing under the loading hopper.

EFFECT: quality of grain drying is improved.
