Abstract
A novel filter assembly (8) for fluid bed granulator, dryer or coater machines (1) which utilize a rigid filter frame (10) consisting of a solid bottom plate (4), a donut shaped top plate (3) with said top and bottom plates being connected by side rods (5) to form a cage like frame work. Said rigid filter frame (10) is reusable, around which a pleated (13) reusable flexible filter bag (9) is fitted and clamped (7), top support plate (2) and mounting plate (12) are connected by a threaded rod (6) with a sealing gasket (11) between them. Said filter assembly (8) is located inside said fluid bed machine's exhaust path so that when the process air is drawn through the filter bag (9) it forms around and through the filter frame (10) to cause a pleated (13) accordion effect in such a way that it allows the use of flexible filter media in a configuration that takes less space, gives better support to prevent tearing, is much easier to change and clean between product production run and can be continuously cleaned during operation by alternately providing reverse air flow through them.
