<p>PURPOSE:To efficiently fluidize carrier particles with a small quantity of fluidizing air and to uniformly coat the carrier particles with a resin with decreased collapse of the carrier particles and formation of flocculated particles by spraying a resin liquid while applying vibrations to a fluidized layer. CONSTITUTION:A fluidization chamber 4 is provided apart a dispersion plate 3 in the upper part of an air chamber 2 having a supply port 1 for pressurized heating air and a vibration block 5 exists in the lower part of the body. A vibration motor 7 connected to an inverter 6 is disposed on a spring 8. A spray nozzle 9 is disposed at the center of the body and a discharge port and filter 10 are disposed in the upper part. The carrier particles 11 are charged at 1/2 to 1/3 capacity ratios into the fluidization chamber 4 and are fluidized by the pressurized heating air and further, the force vibrations of the vibration block are applied to the carrier particles, by which the carrier particles 11 are vibrated and fluidized. The resin liquid is sprayed from the spray nozzle 9 and while the carrier particles 11 are uniformly fluidized, the carrier particles are uniformly coated with the resin.</p> |
