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.

Abstract

A fluid bed apparatus module (1) comprises an outer wall enclosing a processing chamber (9) and has a lower flange connection (4) and an upper flange connection (5), the lower flange connection being adapted to connection with a flange connection (14) of a supply of fluidising gas, and the upper flange connection being adapted to connection with a flange connection (17) of a filter chamber (18) for gas discharge. At least one partition element (6) is arranged in the processing chamber, so that at least one elongated channel is formed in the processing chamber, thereby defining a plug-flow area, and at least one substantially continuous product inlet (10) and at least one substantially continuous product outlet (11) are arranged in the module. Furthermore, a method comprises changing a first module for a second module in a fluid bed apparatus.

Abstract

A transition piece (1) for the transfer of powder or granular material from a larger diameter discharge opening to a smaller diameter conveying line comprises a housing (2) having an inlet end (3) mating the discharge opening and an outlet end (4) mating the conveying line. The housing (2) is provided with a flexible liner (10) having a first end and a second end that has a substantially smaller cross-sectional dimension than the first end. The circumference of the flexible liner is connected in a fluid tight manner with the housing (2) at each end of the flexible liner (10), so that an annular enclosure (19) is formed between the flexible liner (10) and the housing (2). The annular enclosure (19) communicates with a control fluid connection (20).
