PURPOSE:To carry out stirring simply without hindering classifying and dispersing capacities, by providing a stirrer supporting and driving a fluidized bed without piercing the center thereof to the lower part of a fluidized bed apparatus. CONSTITUTION:A fluidizing gas blow-in chamber 6 is provided to the lower part of a blow-in port 4 so as to be almost aligned to the axis of said blow-in port 4 and a hollow rotor 1 is coaxially provided in said gas blow-in chamber 6 and a stirring arm 5 or a support thereof is connected thereto and subjected to rotary motion along the bottom of a fluidized bed, the blow-in port 4 and the peripheral wall of the blow-in chamber 6 to stir the fluidized bed. As described above, because the stirring of the fluidized bed is carried out obliquely, the classifying and discharging capacity of a coarse substance at the blow-in port 4 and the dispersing capacity of a fluidizing gas to the bed are not hindered. |
