Fluidized bed granulation coating apparatus and fluidized bed granulation coating methods

摘要

PROBLEM TO BE SOLVED: To continuously perform treatment based on respective processes constituting a fluidized bed granulating and coating process in a fluidized bed granulating and coating method.;SOLUTION: A drying section 20a for drying a granulated powdery particulate is provided under a granulation section 10a for subjecting a powdery particulate to a fluidized bed granulating and coating process and a drying section 30a for drying the powdery particulate not dried sufficiently is provided under the drying section 20a and a product discharge section 40a for discharging a product after drying is provided under the drying section 30a. Fluidized bed forming air is supplied from below to above to continuously perform granulation and drying, and the powdery particulate transferred to the drying section immediately under the granulation section is classified by wind force.;COPYRIGHT: (C)2002,JPO
