Abstract
Apparatus for suspending particles in a fluidized bed within a coating chamber where the particles are coated with a substance contained in a reactant gas introduced into the chamber by means of a centrally arranged nozzle extending upwardly from the coating chamber floor. Levitating gas for suspending the particles in the fluidized bed is introduced into the chamber from around the centrally arranged nozzle and generally parallel with the chamber base to promote particle circulation through the fluidized bed and minimize deposition within the chamber in one species of the apparatus, the nozzle is supported upon a movable probe which forms a closure for an opening in the chamber base through which coated particles are unloaded.
