PURPOSE:To facilitate setting of conditions for fluidizing process by providing a transfer passage for fluidized material between at least one set of partitions formed at each inlet for fluidized fluid. CONSTITUTION:A large quantity of fresh granules fed from a supplying machine 9 are fluidized on the bottom 2. The granules are transferred to the bottom 3 through a transfer passage consising of a flow-out port 22, ducts 12, 15, 13, a regulating valve 16 and flow-in port 23. The transfer passage branches ducts 15, 13 and is formed among plural numbers of bottom 3. The main flow of the fluid is sent in the tangential direction from feeding ducts 7, 8 to feeding chambers 4, 5, and sent in a fluidized state to bottoms 2, 3 of a fluidized bed 1 formed in the fluidization chamber. The flow spreads over the bottom, and maintains a stable fluidized bed for which temperature and material distribution are easily controllable. |
