The BGB-B Series high efficiency film coating machine is mainly used in pharmaceutical and food industries. Featuring mechatronics and conforming to the requirement of GMP, it is a high efficiency, energy saving, safe and clean equipment for coating tablets, pills and candies with organic film, water soluble film, slow and controlled release film, sugar film and etc.

Working principle

The tablet cores to be film coated make continuous complicated orbital motion within the closed rotating drum under the action of a streamline guide plate. During the motion, coating medium automatically sprays according to the technological process and rational technological parameters, at the same time hot air is supplied under a negative pressure. The hot air penetrates through the tablet core layers and is discharged form the bottom of the layers, so that the coating medium sprayed on the surface of tablet cores will dry rapidly and evenly, thus forming a solid and smooth surface film.
