ABSTRACT:
Apparatus for transporting materials to, from and through the cavity of a microwave unit is disclosed, said apparatus embodying microwave energy cut-off means which is effective to prevent any undue microwave leakage from escaping therethrough. The apparatus in one form comprises a transporter unit which includes an endless transporter belt means disposed in a housing connected to the microwave unit, the transporter belt means feeding the material being treated onto and receiving treated material from a further conveyor unit within the microwave unit, the belt means traversing tunnels in the housing which function as cut-off tubes to prevent microwave leakage from the cavity of the microwave unit, the tunnels having a cross-sectional configuration and length such as to provide for the desired degree of power attenuation. For example, for a microwave unit operating at 2450 MHz the tunnels can be square and have a maximum or longest side dimension of about 1.7 inches and a length of about 10 inches. In another form of the apparatus, the materials being treated are carried through the microwave unit on a plurality of belts, there being cutoff tunnels associated with the plurality of belts and connected to the microwave unit structure at the location where the belts make entry and exit from the microwave unit.
