Patent ID: 7297314

Claim:
A fluidized bed apparatus used for coating processing or granulation processing of powder particles, comprising a processing container, a draft tube arranged inside the processing container, and a disintegrator mechanism for dispersing agglomerates of powder particles by a mechanical disintegration force, wherein a fluidizing gas introduced through a bottom portion of the processing container causes powder particles in the processing container to form a fluidized bed in which the powder particles circulate so as to ascend through a space between an inner wall of the processing container and the draft tube, and descend through an inner portion of the draft tube, and agglomerates of the powder particles descending through the inner portion of the draft tube are dispersed by the disintegrator mechanism, and wherein the fluidized bed apparatus further comprises a rotary rotor for sending the powder particles that have passed the disintegrator mechanism to an upward current of the fluidizing gas by centrifugal force.
