DEVICE FOR GRAIN DRYING Russian patent published in 2017 - IPC F26B17/28 

FIELD: agriculture.

SUBSTANCE: device for grain drying comprises the casing covered with a layer of a heat-insulating material, the loading hopper, the unloading window, the conveying working body mounted within the casing, the heating elements, the fan and the air duct connected to the inner casing cavity. The casing is made rectangular in cross section. Plates are installed inside and along the casing, vertically and parallel to one another. The conveying working body is made in the form of shafts mounted on the plates with the possibility to rotate in one direction. The shafts are arranged in parallel to one another and at an equal distance therebetween in one plane from the loading hopper to the unloading window. Flow guides, the upper surface of which is inclined in the grain movement direction, are mounted between the shafts on their upper side on the plates. The gap between the shafts and the flow guides is made smaller than the minimum grain size. The air duct is installed on the upper side of the casing. The heating elements are installed in the air duct.

EFFECT: improving the quality of grain drying due to the quick and uniform heating of the grain.
