ABSTRACT:
A dryer has suction loading on both sides to save space and to allow washed materials to be loaded into the dryer from plural spaces at different levels without the need for any additional conveying equipment. The dryer comprises first and second flexible tubes and a suction fan for drawing the washed materials from loading stations, through the first and second flexible tubes, and into the drum of the dryer. A flap is inserted in each flexible tube to selectively connect the drum as well as the fan to the respective loading station during loading, and to seal the respective connections during drying. The flaps may be either mechanically or automatically actuated.
