GRAIN DRYING DEVICE Russian patent published in 2024 - IPC F26B17/12 F26B17/26 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to grain drying devices. Grain drying device comprises a casing, the surface of which is coated with a layer of heat-insulating material, a loading neck, an unloading window, heating elements, a fan, an air duct, as well as a transporting working element installed inside the casing, which is installed on elastic elements with the possibility of transmitting oscillations to it. Fan is installed in the central part of the casing. Transporting working element is made multi-section and represents rigidly connected and installed in parallel one above the other perforated plates. Sections are installed in pairs one above the other so that they have the same angle of inclination directed upwards and downwards to the vertical. Heating elements are installed on the lower side of the perforated plates. Perforated plates are made from heat-conducting material. Distance between perforated plates is not more than 2 times greater than maximum grain size. Fan is installed in the central part of the casing. Air ducts are located between paired sections of transporting working element and are directed to inner walls of casing, which are made perforated.

EFFECT: higher quality of grain drying.
