Abstract
A bulk material dryer of the through flow type is equipped with an air permeable bulk material conveyor for carrying the bulk material through a dryer housing. The inlet and outlet ends of the dryer housing are sealed by paddle wheels, the paddles of which dip into the layer of bulk material on the bulk material conveyor. A moving filter belt is arranged in the dryer housing in such a position that dust laden air that has passed through the bulk material must also pass through the moving filter belt for the continuous cleaning of the drying air. One or more cleaning devices are arranged along the moving filter belt for in turn cleaning the filter belt, thereby assuring a continuous drying operation.
