PROBLEM TO BE SOLVED: To provide a wind force selector without necessitating soundproof and vibration-proof countermeasures and capable of greatly increasing the treatment quantity without increasing a space. SOLUTION: This device is provided with a tubular casing 1 installed horizontally or slantringly at a specified angle, an air forced port 4 provided on one end of the casing 1 and forcing a high speed of air toward the longitudinal direction inside the casing 1, a charging port 6 provided on the upper surface of the casing 1 at the downstream side of the air forced port 4 and sucking a moterial to be treated into the casing 1 with the prescribed air stream, an air sucking port 7 provided on the upper surface of the casing 1 at the more downstream side than the charging port and sucking the air with a required speed and a discharge port 10 provided on the other end part of the casing 1 and discharging the material to be treated. |
