  • Patent number: 8893895
    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.

  • Patent number: 6629003
    Abstract: In a method and system for operating a batch processing machine which produces a product, a recipe is created with a computer for batch processing of the product, the recipe having a plurality of steps. For at least one of the steps the machine is first manually operated and a snap shot is taken of control element operating parameters. The snap shot is then used for assisting in the creation of at least one of the method steps of the recipe. The recipe then is used to automatically process a batch of the product. Also, the batch processing machine can switch between a recipe editing screen and a recipe matrix screen, the recipe matrix screen providing control element indicia on one axis and steps of the process on a perpendicular axis, and wherein at locations of the matrix control element parameter values are displayed. Also for management reporting, a format of a management report can be changed for a given batch after running the batch.
