FIELD: heating; agriculture. ^ SUBSTANCE: device for grain heating comprises shaft with inlet and outlet pipelines. Heating elements are installed in shaft in tiers, and heating elements are arranged in the form of flat multi-electrode composite electric heaters installed in shaft with the help of support elements, with the possibility of rotation relative to horizontal axis and are equipped with mechanism for their rotation, at that every flat multi-electrode composite electric heater is encased into wear resistant heat-conducting shell. ^ EFFECT: considerable increase of heating elements heating surface, reduction of power inputs for grain heating, reduction of device material intensity and improved performance reliability. ^ 2 cl, 2 dwg |
