PROBLEM TO BE SOLVED: To provide a spray-drying agglomeration device capable of producing stable agglomerate particles having a particle diameter of 300 μm or more, preferably of 600 μm or more, the invention having an intention that the device be operated as economically as possible and that the process be designed such that the obtainable agglomerate particles have an improved product quality.SOLUTION: The spray-drying agglomeration device has: (i) a spray-drying segment A arranged in an upper region of a chamber for drying particles of the liquid feedstock sprayed from a liquid feed atomizer Z1; and (ii) a fluidized bed B arranged in a lower region of the chamber, the fluidized bed B having a nozzle or atomizer structure mounted at the bottom thereof for spraying a liquid binder to powder at the spray-drying segment, in which the powder have been spray-dried in the step (i). The particles are constantly kept fluidized during production.SELECTED DRAWING: Figure 1 |
