Poreless Film Coating Machine
The Poreless Film Coating Machine integrates elegance, high efficiency, safety, and is easy to clean and suitable for applying coating to tablets, microtablets, pellets, microgranules, with sugar, organic film and water soluble film. Its operation process and process parameters such as negative pressure and temperature can be automatically controlled by PLC and HMI.

Basic working principle:
The tablets make a continuous, complex, orbital motion in the closed drum of the film coating machine. The mixed coating is sprayed on the tablets with the spray gun through the action of the peristaltic pump.

Meanwhile, under the action of the Air Exhaust Cabinet (creates negative pressure) and Hot Air Cabinet (supplies hot air), a 100,000 level purification of clean hot air, supplied by the Hot Air Cabinet, blows into the drum through the air distribution pipe and penetrates the tablets. They are then exhausted from another side of the air distribution pipe and discharged. This allows the coating medium, which is sprayed on the surface of the tables, to dry rapidly and evenly, thus forming a solid and smooth film surface.

Characteristics:

1, Under the action of the streamlined guide plate, the tablets tumble frequently and smoothly, preventing them from colliding. This prevents broken pieces and chipped edges and improves the rate of finished products. The narrow surface of the guide plate eliminates the adhesion of coating material on its surface, thus conserving coating material and improving the quality of medicine.
2, During air intake, a three-filter process involving primary filtration, medium filtration and high filtration, can reach 100,000 level purification.

During air exhaust, the dust collection filter can reach 99% by adopting a dust extractor.
3, Thanks to innovative design, the fan propeller in the air source system can be exchanged as an air inlet or air outlet depending on the technological requirements. The propeller' s hole can range from 0.6 to 3.00 mm diameter, making it suitable for types of microtablet coatings.
4, An explosion-proof lamp is equipped in the drum to allow for observance of the coating process.
