FLUIDIZED BED GRANULATION COATING DEVICE, AND FLUIDIZED BED GRANULATION COATING METHOD

摘要

An upper processing section (10) is provided by evenly spacing out functional stations (13) having respective functions of steps constituting a fluidized bed granulation coating process, on circumferential points. An intermediate storing section (20) is provided under the upper processing section (10) by evenly spacing out powder grain storing vessels (22) corresponding to the plurality of functional stations (13) on circumferential points. A lower gas supply section (30) is provided under the intermediate storing section (20) by evenly spacing out gas supply stations (31) corresponding to the plurality of powder grain storing vessels (22). The powder grain storing vessels (22) storing powder grains sequentially proceed to the respective functional stations (13) to execute respective processes to the powder grains, and thereby granulation coating of the powder grains is performed in a batch type and a continuous type. Alternatively, the plurality of functional stations having respective functions of steps constituting the fluidized bed granulation coating process may be disposed on a straight line.
