ABSTRACT:
A dryer is provided which is adapted to receive and dry polymeric material. The dryer comprises a support structure, a drying hopper assembly, a polymeric material supply device and a controller. The drying hopper assembly includes a drying hopper having an inlet for receiving wet polymeric material to be dried and an outlet through which dry polymeric material exits the hopper, and load cell apparatus associated with the support structure and the drying hopper for sensing the weight of the drying hopper and any polymeric material contained therein. The load cell apparatus generates first signals representative of the weight of the drying hopper and any contents it may have. The polymeric material supply device is adapted to supply wet polymeric material to the drying hopper through the material inlet. The controller is coupled to the polymeric material supply device and the load cell apparatus. It receives the first signals generated by the load cell apparatus and controls the operation of the polymeric material supply device based thereon.
