ABSTRACT:
A continuous granulating and drying apparatus comprises a granulator and a fluid bed dryer. The fluid bed dryer comprises at least two separate processing compartments forming part of a common vessel being provided with radially extending partition walls separating the processing compartments from each other. Each processing compartment has a product inlet and a product outlet. The fluid bed dryer comprises a granulated product supply conduit arranged rotatably to selectively communicate with the product inlet of each separate processing compartment, respectively, and a product discharge conduit arranged rotatably to selectively communicate with the product outlet of each separate processing compartment, respectively. The granulator and the fluid bed dryer are closely coupled.
