DEVICE FOR GRAIN DRYING Russian patent published in 2017 - IPC F26B17/26 

FIELD: agriculture.

SUBSTANCE: device for grain drying comprises the casing, the surface of which is coated with a layer of heat-insulating material, the loading hopper, the unloading window, the heating elements, the fan, the air duct, and the conveying working body installed inside the casing. The upper casing surface is made horizontal. The lower casing surface is inclined downward from the loading hopper to the unloading window. The conveying working body is made in the form of a box installed with the possibility of transmitting oscillations to it and changing the inclination angle relative to the horizontal. The upper surface of the box is made stepped. The lateral surfaces of the steps are made perforated, wherein the perforation diameter does not exceed the minimum grain size. Heaters are installed under the upper surfaces of steps. The air duct is connected to the internal box cavity. The heating elements are installed in the air duct.

EFFECT: improving the grain drying quality due to the uniform heating of grain by air flow.
