ABSTRACT:
A grain dryer has a horizontal plenum connected to a source of heated forced air and has at least one generally perforated wall. A substantially enclosed grain conduit extends along the plenum and has one of its sidewalls being the perforated wall of the plenum. The grain conduit has upper and lower ends to receive and discharge, respectively, a quantity of grain to be dried by heat conveyed to the grain through the perforated wall of the plenum. The lower end of the grain conduit defines an opening generally dwelling in a substantially vertical plane and having upper and lower discharge ports, separated by a plate extending across the central portion thereof to close the flow of grain therethrough. Generally horizontal upper and lower feed rolls are located in the grain conduit adjacent each of the upper and lower ports, respectively, to induce flow of grain out of the upper and lower ports, with the feed roll adjacent the upper port serving to accelerate the discharge of a layer of hotter grain adjacent the vertical wall of the grain conduit. A flange extends inwardly from the plate in spaced relation to the vertical wall of the grain conduit to guide a layer of hotter grain adjacent to the wall out of the grain conduit.
