摘要：A process and an apparatus for the continuous crystallization of plasticgranules, particularly amorphous plastic granules, in which the granules are introducedinto a container and form a granule bed, which is moved downwards by the action ofgravity. A hot gas is passed as a primary gas in a countercurrent manner through thegranule bed. The granules are kept moving by a stirrer. There is also a gas supply for asecondary gas, which introduces the secondary gas at high speed at several pointsdistributed over the cross-section of the container into the upper area of the granulebed.
