Usage:
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.

Features:
All the operations, including expansion of PLC module, setting and control of hot air temperature and adjustment of drum speed, are carried out on the touch keys of control panel of computer, and the operating panel is a fully closed light touch film interface which does not influence the cleaning of main machine, thus featuring reliable work, stable performance and conforming to the requirement of GMP.

Under the action of the agitator of steam line guide plate type, the tablet cores are tumbling smoothly and exchanging frequently, thus eliminating the phenomenon of tablet cores to fall from a high place and to collide, solving the problems of broken pieces and chipped edge, and improving the rate of finished products. The narrow surface of the guide plate eliminates the adhesion of coating material on its surface, thus saving the coating material and improving the quality of medicine.

The peristaltic pump with constant pressure variable eliminates the need for a return pipe. The turning radius of the drum varies along with the pressure change. The output slurry and the quantity of slurry sprayed are balanced automatically, thereby stabilizing the effect of atomization, simplifying the spray system, preventing the spray gun from plugging-up, and saving the coating material, moreover the cleaning is simple, and there is no dead corner.

The spray gun specially designed for the film coating machine features even atomization and large coverage of spraying. The universal adjustable spray head makes the cleaning mechanism of spray gun unaffected by charge quantity, so that film coating can proceed continuously, thus reducing the film coating time and saving film coating material.
