Particle coating apparatus for small-scale processing

摘要

Apparatus and methods are provided for coating relatively small quantities of particles including tablets, pellets, or granules. The device effectively fluidizes the particles to be coated by controlled vibration of a perforated platform through which drying air is passed during intermittent spraying of the particles with a solution of organic or aqueous-based coating material. The method coats individual tablets having as low a mass as 50 mg and coats quantities ranging from less than about 50 mg to 10 g of tablets, pellets, or granules.
