Rotary Microwave Apparatus for Continuous Heating of Materials

摘要

A microwave furnace for heating materials is disclosed comprising two microwave chambers made of microwave reflective material for retaining microwaves, one of the chambers is fixed and having an opening for discharging the heated material. The other chamber is a rotating drum. The furnace also comprises an elongated tubular member, having a first and second open end, the tubular member being made of a microwave transparent material and is being retained within the microwave chamber. A feeding mechanism feeds the material to be heated into the first end of the tubular member. The microwave furnace is provided with a mount for supporting the tubular member within the rotating microwave chamber by clasping the tubular member, the mount adapted to rotate the tubular member along its axis, and positioning the tubular member such that the second end of the tubular member is substantially adjacent the discharge opening of the fixed microwave chamber. Finally, the microwave furnace is provided with a microwave generator for generating microwaves and guiding them into the microwave chamber.
