GRAIN DRYING DEVICE Russian patent published in 2011 - IPC B02B1/00 

FIELD: technological processes.

SUBSTANCE: invention is related to agricultural machine-building, in particular, to grain drying devices. The device comprises a jacket, the surface of which is coated with a layer of a heat insulation material, a transporting working tool installed inside the jacket, a loading hopper, a discharge window, heating elements arranged between a loading hopper and a discharge window, and also a cooling device comprising a fan and an air duct. The jacket is made with a rectangular cross section, and the transporting working tool in the form of a continuous chain with scrapers.

Top of angle in one of the scrapers is directed along with the conveyor motion, and in the other one - oppositely. In the middle part of the scraper with the top angle directed oppositely to direction of the conveyor motion, and also those parts that are most distanced from each other in the scraper, the angle top of which is directed along the conveyor motion, there are holes made of rectangular shape. Inside the jacket there is a plate installed horizontally, and the lower side of the plate there are heating elements installed. The upper part of the chain with scrapers rests against the plate. The air duct is installed above the plate at the equal distance from the loading hopper and the discharge window.

EFFECT: using invention allows to increase finished product quality.
