Disclosed is an improvement in a drying apparatus comprising a cylindrical drying vessel, the inner wall surface of which makes up a heat-transmitting surface, a heat-generating means encircling the cylindrical drying vessel, and at least one rotating vane assembly rotatably fixed in the cylindrical drying vessel. The rotating vane assembly has vane sections, which leave between their circumferential edges and the heat-transmitting surface of the hollow cylinder an annular space small enough to allow wet material to cross and contact the heat-transmitting surface without falling therein. Each vane section extends obliquely upward in the direction which is opposite to the rotating direction, and the circumferential edge of each vane section extends less than 360 degrees as viewed from the top. All vane sections when rotating bear material on their upper surfaces to raise and push material against the heat-transmitting surface under the influence of centrifugal force, thus causing it to continuously climb along the heat-transmitting surface for drying.
