BGB-B Series High-Efficiency Film Coating Machine
Usage:
The BGB-B Series high-efficiency filmcoating machine is mainly used in
pharmaceutical and foodstuff industries. 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 filmcoated 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 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 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 streamline guide plate type, the table 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 filmcoating 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 filmcoating
can proceed continuously, thus reducing the filmcoating time and saving
filmcoating material.
