GRAIN DRYING DEVICE Russian patent published in 2024 - IPC F26B17/26 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to grain drying devices. Grain drying device comprises a rectangular cross-section casing, the surface of which is coated with a layer of heat-insulating material, a loading bin, discharge opening, fan, air duct, heating elements installed inside the air duct, transporting working element installed inside the casing and oscillating motion drive. Transporting working element is made in the form of a keyboard conveyor, the surface of which is made with a gradually increasing inclination to the horizontal in the direction of the discharge window, wherein the width of the keys and the distance between adjacent keys are made less than the thickness of the grain, wherein when the keys vibrate, the grain during its movement periodically falls from the raised key to the neighbouring lowered one, changing its position relative to the air flow, being uniformly blown by it from all sides, keys are made of heat-conducting material; on the outer side of the outermost keys of the transporting working element there are sides installed along their entire length, and the air duct is installed in the lower part of the casing.

EFFECT: quality of grain drying is improved.
