Method and apparatus for continuously coating discrete particles in a turning fluidized bed formed in a cylindrical coating vessel with a rotary disk at the bottom thereof by blowing hot air into the vessel through air blow holes located between the circumference of the disk and cylindrical side wall of the vessel while spraying a coating material into contact with the particles in the turning fluidized bed, characterized by introducing a particulate raw material and a coating material into the turning fluidized bed at constant feed rates; and discharging coated particles at the same rate as the feed rate of the particulate raw material through a particle discharge port located at such a height as to guarantee an average residence time corresponding to a desired coating rate under given operating conditions including the feed rate of the raw material, the rotational speed of the disk and the feed rate of hot air.
A method of continuously coating discrete particles in a turning fluidised bed formed in a cylindrical coating vessel with a rotary disk at the bottom thereof by blowing hot air into the vessel through air blow holes located between the circumference of said disk and cylindrical side wall of said vessel while spraying a coating material into said vessel for contact with the discrete particles in the turning fluidised bed, characterized in that said method comprises:
An apparatus for continuously coating discrete particles in a turning fluidised bed, comprising in combination:
