Abstract
An in-line microwave applicator has an electromagnetic energy wave generating unit which transmits waves, particularly microwaves, dispersing from a longitudinal axis. The dispersing waves are interrupted by microwave diverters which cause the wave lengths to be transmitted through holes from the first chamber to a second surrounding chamber. The second surrounding chamber has interior walls which are reflective to the microwaves and may have a spiral rib to enhance reflectivity. Product for heating is passed through the second chamber to be irradiated by microwaves exiting the holes from the first chamber. The holes are generally elongate in shape and can be surrounded with microwave transparent material to prevent material from falling through. The microwave diverters can be protrusions extending from the holes into the inner chamber by increasing amounts as the distance from the microwave energy generating unit increases. Alternatively, cones placed at varying angles, a generally spiral shape member, or a series of disks can be used as microwave diverters. Product can be carried through the second chamber using a single or variable pitch helix or screw.
