GRAIN DRYER Russian patent published in 2022 - IPC F26B17/04 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, 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 heat-insulating material, inside the casing there is 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 duct. The box 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. A plate made of heat-conducting material is installed in the lower part of the casing. Heating elements are installed on the inner side of the upper part of the box and on the lower side of the plate. The air duct of the cooling device is installed on the side of the casing. The casing wall located opposite to the air duct is perforated. The unloading window is located at the bottom of the casing under the loading hopper.

EFFECT: quality of grain drying increases.
