Abstract
Apparatus for drying products of various types including particulate materials having varying degrees of moisture content including those moistened throughout, as by organic solvents, and which may be tacky in nature; the apparatus including a generally cylindrical vessel with a downwardly conical lower portion terminating in a dried product discharge opening, and a gas inlet conduit arranged to deliver a drying gas to the vessel in the region of and slightly above the discharge opening at relatively low pressure but with auxiliary screw or propeller arrangements for preventing access of the product, particularly if tacky, to the gas inlet conduit and also serving to assist in distribution of the drying gas throughout the product as it is agitated and distributed in the vessel and in countercurrent as it tends toward the discharge opening.
