An apparatus is provided for heating and melting materials using microwave energy, and for permitting them to solidify. The apparatus includes a microwave energy source, a resonant cavity having an opening in its floor, a microwave energy choke encompassing the opening in the floor of the cavity, a metal container to hold the materials to be heated and melted, a turntable, and a lift-table. During operation, the combined action of the turntable and the lift-table position the metal container so that the top of the container is level with the floor of the cavity, is in substantial registration with the floor opening, and is encompassed by the microwave energy choke; thus, during operation, the interior of the container defines part of the resonant cavity. Additionally, a screw feeder, extending into the cavity and sheltered from microwave energy by a conveyor choke, may convey the materials to be heated to the container. Also, preferably, the floor of the resonant cavity may include perforatins, so that the offgases and dust generated in the apparatus may be removed from the resonant cavity by pulling outside air between the container choke and the exterior wall of the container into the resonant cavity and out from the cavity through the perforations.

A microwave apparatus for heating materials, said apparatus comprising: a microwave energy input for delivering microwave energy, a resonant cavity for receiving microwave energy through said input, said cavity including a ceiling, walls, and a floor, said floor having a floor opening, a microwave energy choke encompassing said floor opening of said resonant cavity, a microwave energy reflective container for holding said materials to be heated, said container having a top portion at least as large as said floor opening of said resonant cavity, a floor portion, wall portions, and an interior, and capable of being positioned to bring said top portion level with said floor of said resonant cavity, and in substantial registration with said floor opening of said resonant cavity, means for turning said container during exposure of said materials in said container to microwave energy, located outside of said cavity, and means for lifting said container, located outside of said cavity, whereby said means for turning is placed on said means for lifting, and said container is placed on said means for turning and lifted by said means for lifting to bring said top portion of said container level with said floor of said resonant cavity and in substantial registration with said floor opening of said resonant cavity, said choke encompassing said top portion of said container, and whereby said floor portion and said wall portions of said container define a bottom floor portion and bottom wall portions of said resonant cavity and said interior of said container defines part of said resonant cavity, and whereby said materials in said container are exposed to microwave energy, are melted, and are permitted to cool and solidify.
