ABSTRACT:
A rotary drum type apparatus for applying a coating to tablets including a rotary drum supported by a support frame for receiving a body of tablets to be coated by spraying with a solvent. The drum is inclined through about 10-20 degrees in such a manner that its front surface is turned upwardly, and an air inlet tube and an air outlet tube are connected to the support frame in positions slightly displaced toward the rear surface of the support frame from the center line of the support frame extending perpendicular to the center axis of the drum. The support frame cooperates with an outer periphery of the drum to define an air suction duct disposed on the front side of the support frame and an air exhaust duct disposed on the rear side of the support frame so that a smooth flow of hot blast through the drum can be obtained.
