ABSTRACT:
A coating-fluidizing gas supply system for a flat-bottom fluidized bed coater that maintains a high degree of uniform fluidization of levitated particles for a long enough time period to coat medical-device components. The coating-fluidizing gas supply system prevents premature pyrolysis of the coating component of the gas from plugging gas-distributor holes of a flat plate at the bottom of a flat-bottom fluidized bed coater, by directing multiple gas streams uniformly against the entire undersurface of the flat gas-distributor plate, creating an overall cooling-effect on the gas-distributor plate which prevents clogging.
