摘要

Device for introducing hot air to dry materials comprises fixed supported covering shields (21) arranged on an air distribution pipe (14). The shields are arranged at a short distance from the outer casing surface. Outlet nozzles (15) inserted into the distribution pipe and the size and number of shields are coordinated with each other in such a way that at least one row of nozzles brushes over a free space provided between the shields during rotation of the distribution pipe. Preferred Features: The shields are arranged at an angle of 45-90, preferably 60 deg . The air distribution pipe is composed of four uniform segments with right angled flanges.
