    摘要: The present invention provides a method and apparatus for dry coating solid dosage forms. The method includes the steps of placing solid dosage forms in a rotatable, electrically grounded housing, and spraying a film forming polymer powder composition into the housing during rotation thereof to form a polymer coating on the solid dosage forms, the polymer powder composition being sprayed using an electrostatic spray gun, and curing the coated solid dosage forms.

    摘要: The present invention provides a fluidized bed for dispensing small quantities of powders. The fluidized bed is made using a porous housing to permit injection and removal of fluid through the surrounding walls to improve the operation of the bed particularly for small particles of the group C size, including significantly reducing powder adhesion to the walls. In one aspect of the invention the fluidized bed housing is rotated about its longitudinal axis, which may be oriented at any suitable angle. A system for changing the volume of the bed is described as is a system for incorporating injection nozzles within the bed for constant agitation and prevention of powder adhering to the walls of the housing.
