Abstract
My continuous drier comprises an inclined tubular casing having a feed tube concentrically disposed therein via which the product, such as grain or seed, to be dried is delivered to the lower end of the casing. Circumscribed about the feed tube and in a fixed relation thereto is an auger having its peripheral edge secured to the interior of the tubular casing. Most of the flights of the auger are perforated, the holes being of a size sufficiently small so that the granular product will not pass therethrough, yet large enough to allow a heat conductive media, such as salt particles, to sift downwardly as the drier is rotated about its inclined axis. Whereas most of the auger is perforated, two flights adjacent the closed lower end of the casing are imperforate. A discharge opening is provided in that portion of the feed tube encircled by the imperforate flights, thereby enabling the granular product to be delivered into a region adjacent the lower end of the tubular casing which is devoid of any heat conductive particles. Heat is directed to the outside of the tubular casing, passing through the casing wall directly into the granular product and also to the product through the agency of the various heat conductive particles.
