FIELD: agriculture.SUBSTANCE: invention relates to the agricultural industry, in particular to devices for drying grain. The device for drying grain comprises a casing of rectangular cross section, which surface is covered with a layer of heat insulating material, a loading hopper, an unloading window, heating elements located between the loading hopper and the unloading window, the conveying working body mounted inside the casing, and also a cooling device consisting of a fan and an air duct. The conveying working body is made in the form of an endless flexible cell belt. Inside the casing between the upper and lower branches of the conveying working body two sequentially connected boxes in the form of rectangular parallelepipeds are mounted, which total length is limited by the outer edge of the loading hopper and the outer edge of the unloading window. And the dimensions of the lower base of the second box are equal to the dimensions of the cross-section of the unloading window. The side and the lower surfaces of the first box are made of heat insulating material and the upper is made of thermally conductive material. The upper and lower surfaces of the box located above the unloading window, and also the upper surface of the other box are made perforated, with diameter of perforation not exceeding the minimum grain size. The heating elements are mounted under the upper surface of the box. The air duct is connected to the cavities of each box.EFFECT: use of this device enables to improve the quality of grain drying and to reduce energy consumption.1 dwg |
