FIELD: heating, drying.SUBSTANCE: invention refers to agricultural engineering, and namely to grain drying devices. The grain drying device includes a cylindrical casing, the outer surface of which is coated with a heat-insulating material layer, a loading bunker, an unloading opening, a transporting working element, heating elements, a fan and an air pipeline. The casing is made in the form of a horizontally located cylinder divided into two parts along a horizontal symmetry axis. Upper part of the casing is removable and made from heat-reflecting material. The transporting working member is made in the form of a screw with a hollow perforated shaft. Screw perforation is made between the loading bunker and the unloading opening with diameter of the openings, which does not exceed minimum grain size. The casing lower part and the screw are made from heat-conducting material. Heating elements are located on outer surface of the casing lower part under the heat-insulating material layer. The air pipeline with a fan are connected to inner cavity of the screw shaft, and a heater is installed in the air pipeline.EFFECT: reducing energy costs for moisture evaporation process and simplifying maintenance of the device.2 dwg |
