ABSTRACT:
The invention relates to an apparatus and method for the uniform treatment of the surfaces of a plurality of individual parts when such parts are processed as a single heap by introducing a mass of parts into a vessel where they form a heap; introducing a treatment medium into the vessel; repeatedly separating and dispersing the parts from the heap and then returning the parts back into the heap in during controlled cycles so that all surfaces of the parts to be treated are exposed to and contacted by the treatment medium. While the parts are separated and dispersed from the heap, the treatment medium is forced around, through and out from the parts so that, after a number of cycles, all surfaces of the parts are uniformly treated by said treatment medium. The parts move back and forth between a first position in a lower portion of the vessel and a second position above and radially outward from the first position, whereby movement of the parts between the first and second positions enables all surfaces of the parts to be uniformly treated by the treatment medium. The parts treated by this method constitute another embodiment of the invention.
