Flow control meters for gravity flow particle dryers

Abstract From the Canadian patent

Abstract, An improved metering discharge device for particulate material, particularly grain, is described. The device comprises a plurality of tubes extending downwardly from a lower region of a vessel, particularly in uniformly spaced relationship across the bottom of a gravity flow grain drying chamber. Each tube has an upper end flow connected to the drying chamber and a closed lower end and also has a pair of opposed openings in the side walls. A rotatable auger extends laterally through the tube via the side wall openings. The tubes preferably arranged in straight rows with a single auger extending through each row. This combination of tubes and augers provides a simpler design as …
