<p>A particle coating device provided with a jet tower (2), wherein a throttling plate (52) having a plurality of air flow holes (56) drilled therein and coating liquid atomizing nozzles (26) adjacent to the throttling plate (52) are mounted to a jet gas inlet (10) of the jet tower (2), the air flow holes having a total opening area which is 10 to 70% of the inner section area of the inlet. A throttling plate (52) having a plurality of air flow holes (56) drilled therein having a total opening area which is 10 to 70% of the inner section area of the jet gas inlet (10) of the jet tower (2). The particle coating device, wherein particles are supplied to the jet tower (2) having guide pipes (6) thereinside, a heated jet gas is jetted into the jet tower (2) through air flow holes (56) in the throttle plate (52) to form a particle jet layer, a coating liquid is atomized into an atomized flow through coating liquid atomizing nozzles (26), and a coating liquid solvent deposited on the surfaces of particles in a jet condition is evaporated to form coating material coats on the particles.</p> |
