Abstract
The fluidized bed processor of the present invention includes an internal filter assembly with a rack and a cartridge-type filter supported at the lower end by a bracket. The rack includes an elongated rod extending through the filter. An end cap is provided on the lower end of the rod for normal sealing engagement with the filter bracket. During normal operation of the processor, the upper and lower ends of the filter are sealed. During or after cleaning of the filter, the rack is lowered, and a spring separates the filter and support bracket from the end cap so as to create a gap for drainage of cleaning fluid.
