<p>Material treating apparatus comprising a housing and means for conveying material through the housing in a substantially untensioned condition. Agitating and drying means are provided for moving the material rapidly between limiting barriers disposed on opposite sides of the material, the agitating and drying means comprising high velocity air jets directed through these barriers by means of nozzles located on opposite sides of the material. The air blasts from the nozzles, which may be mounted for oscillation, continuously thrust successive portions of the material into and out of abutment with the limiting barriers. The limiting barriers comprise foraminous aprons which are mounted for continuous movement by means of conventional roller chains. The aprons are substantially open and are made of interwoven strands of wire which allow the air jets to pass therethrough but which limit movement of the material. The aprons form a part of a transport means which includes two endless conveyors disposed one above the other. The treated material, during its movement through the dryer, is disposed between the top run of lower conveyor and the bottom run of the upper conveyor.</p> |
