The invention discloses a wind cleaning and dust removing machine. The key point of the technical scheme is as follows: the wind cleaning and dust removing machine comprises a machine body, a rotatingdrum which is rotationally connected in the machine body and is horizontally arranged, and a wind cleaning device which is arranged on the machine body and is used for performing wind cleaning on materials in the rotating drum, wherein dust removing holes are formed in the side wall of the rotating drum; a rotating shaft is rotationally arranged in the machine body along the axis position of therotating drum; an air inlet passage is formed in the rotating shaft along an axial direction; the peripheral surface of the rotating shaft is provided with packing auger blades extending spirally along the axial direction of the rotating shaft; the inner wall of the rotating drum is fixedly provided with a delivery plate in the shape of a spiral line along the peripheral surface; and the inner wall of the rotating drum is provided with baffle plates parallel to the axial line of the rotating drum at intervals. In a process of delivering chilies by virtue of rotation of the rotating drum, the chilies are thrown down from the upper side in a cavity of the rotating drum, wind cleaning is performed in the air, and then the contact area between the chilies is reduced, so that the wind cleaningon the surfaces of the chilies is relatively comprehensive.
