Title of Invention

CONTINUOUS HEAT TREATMENT OF BULK MATERIAL

Abstract A device (1) for continuous thermal treatment of granular bulk material (granulate), in particular for the crystallization of polymer granulate, such as polyethylene terephthalate (PET), with a product inlet (7) terminating in a chamber (2) being the very first chamber disposed upstream and a product outlet (8) following the last chamber being disposed downstream (6), characterized in that the device (1) is provided with several adjacent fluidization chambers (2, 3, 4, 5, 6) with a separate sieve bottom (11) each through which, via a gas inlet (9) a fluidize gas can be injected into the respective chamber (2, 3, 4, 5, 6) in order to fluidize the granulate, such gas can exit via a gas outlet (10) disposed in the roof area of device (1), and the first chamber(2) occupies a large part of the total volume of all chambers (2, 3, 4, 5, 6), and wherein adjacent chambers have a fluid connection by means of product passages (18, 19, 20, 21, 28, 29, 30, 31) in the respective separating wall (14, 15, 16, 17) that are disposed between them.
