ABSTRACT:
A housing encloses a tumbler-type microwave opaque drum operating on a horizontal axis. A microwave power supply is mounted on the housing with the output directed axially into the drum. The drum has an inner coating or layer of microwave insulating material to reduce arcing of microwave energy between the drum and metal articles tumbling therein. A rear portion of the drum has a microwave-transparent perforated wall supported therein which keeps tumbling articles out of the near field of the output of the power means. The drum and the housing have an overlapping microwave seal therebetween to maintain the microwave energy efficiently in the drum. A forced air arrangement is provided for circulating air through the drum and also to pick up heat from the power supply to increase the vapor carrying capabilities of the forced air and to cool the power supply.
