PROBLEM TO BE SOLVED: To provide a rotary screen capable of sufficiently exhibiting the clogging preventive effect, even if a processed product includes moisture comparatively much. ! SOLUTION: A trommel shifter 1 comprises a cylindrical screen rotatingly driven by being slantingly arranged to a horizontal plane, a rotary brush 5 arranged inside the cylindrical screen 2 and rotatingly driven in the opposite direction of the cylindrical screen 2, and a reciprocating nozzle device 4 arranged outside the cylindrical screen 2. The reciprocating nozzle device 4 comprises a plurality of header pipes 41 for guiding pressurized air from a blower 7 and arranged in parallel to the central axis of the cylindrical screen 2, a plurality of air nozzles 42 provided in the header pipes 41, a crank mechanism 45 for reciprocatably driving the header pipes 41 in the extension direction, and a motor 46. Since the processed product stuck to the cylindrical screen 2 is contacted with the air of blowing off from the air nozzles |
