Abstract
A method of coating powder particles includes the steps of circulating an air flow containing the powder particles in a dispersed state therein in a cylinder whose inner wall is wetted with a coating liquid to bring the powder particles into contact with the coating liquid on the inner wall, and drying the powder particles thus coated with the coating liquid. An apparatus for coating powder particles comprises a drying chamber including an inner space for drying powder particles on the surfaces of which a coating liquid is deposited while floating the powder particles by an air flow, a powder-particle feeding device connected to the top of the drying chamber for feeding an air flow containing dispersed powder particles into the inner space through a cylindrical path, and a coating-liquid supplying mechanism for wetting the inner wall of the cylindrical path of the powder-particle feeding means.
