Centrifugal Granulating (Pelleting) Coater combines rotary fluidized bed technology with tangential spray technology, with functions of making core granule, granulating (pelleting), amplification, spheronizing, coating and so on. It is one of the necessary equipment in the production process of solid pharmaceuticals.
The equipment is made of high-quality austenitic stainless steel, the inner and outer surfaces are highly polished, all corners are arc transition, no dead corner, no residue, with well-shaped appearance. Adopts PLC control, which can set parameters as user required to granulating (pelleting), coating and spheronizing, continuously optimize the production process, imporve production efficiency, and meet GMP requirements.
Under the functions of rotary centrifugal force, friction and annular gas buoyancy, the powdered material mixed and glued with appropriate atomized slurry that sprayed in to complete the process of granulating (pelleting), shaping(spheronizing), coating etc.. This centrifugal coater not only has the functions of granulating (pelleting) and coating, but also combined with spinning granulator, extruding granulator and swing granulator to complete the shaping (spheronizing) of pellets by replacing the gear turntable. And its granulating, spheronizing and coating processes are shown below.
