Abstract
Fluidized bed apparatus for use in applying a coating, having a relatively lesser density to particles, having relatively greater densities, by causing passage of a gaseous atmosphere through a bed of the particles. The apparatus includes an enclosure for holding and heating a bed of the particles. A valve network for causing the flow of the gaseous atmosphere carrying a material for forming the coating upward though the bed of particles to fluidize the particles, is provided. The apparatus further includes a conveyor for adding seed particles to the bed and a spillover for removing particles from the bed upon its achieving a predetermined level to limit the height of the bed. The apparatus also has a selectively operable sampler for removing sample of the contents of the bed at a level below the predetermined maximum level.
