Abstract

A continuous microwave furnace (10) with furnace modules (12) is described, which modules, in a series of sequential placement, one after the other, form a heated zone. On the respective housing casing (14) is provided at least one microwave radiating source (30) located at a corresponding radiation window (31). In each respective furnace module (12) a sheet steel bottom (26) is furnished, this being adjustable as to height and is constructed with secondary radiating openings (28). In the continuous microwave furnace (10) is provided a transport apparatus (33), which is constructed of a conveyor belt or transport rollers. Air openings (35) can be supplied, neighboring the radiation window (31) of the respective microwave radiation source (30). The respective radiation source (30) is then combined with an air regulating apparatus (45). A microwave deflection device (52) can be correlated with the radiation window (31) of the respective microwave source (30) in the interior of the corresponding furnace module (12). The microwave radiation source (30) can be combined with a wave guide (62). The bunching of the microwave radiation is accomplished in this last named case by means of rec…
