FIELD: agriculture; machine building.
SUBSTANCE: device for grain drying comprises a casing, the surface of which is covered with a layer of heat insulating material, a transporting working body mounted inside the casing, a loading hopper, a discharge window, heating elements, a fan and air ducts. Casing is made of rectangular cross section. Transporting working element is arranged in the form of continuous chain with scrapers. Inside the casing is mounted a perforated box, made composite. Above the perforated box vertically installed curved in the form of a roll pipe of rectangular section. Beginning of the pipe is located above the end of the components of the perforated box. Output end of the bent pipe is made perforated and installed above the beginning of each adjacent component of the perforated box. Upper branch of the chain with scrapers is made resting on the upper part of the perforated box. Width of the curved pipes perform equal to the width of the transporting working body. Heating elements are installed inside the component parts of the box on the lower side of their upper part. Ends of the ducts are installed vertically on the lower side of the upper part of the perforated box opposite the beginning of the bent pipes.
EFFECT: improvement of quality of drying due to alternation of cycles of heating and cooling of grain.
