ABSTRACT:
A fluidized bed apparatus and method are disclosed for coating, granulating and/or drying particles. The particles are circulated within a chamber by means of circumferential air flow. A first gas stream moves upwardly through the chamber. A second gas stream enters the chamber through openings in the side wall of the chamber. The openings extend generally horizontally and tangential to the side wall so that the second gas is directed circumferentially in the chamber for three-dimensional rotation and circulation of the particles.
