Usage
It's a kind of equipment integrating elegance, high efficiency, energy-saving, safety, easy to clean, which is applied for coating traditional Chinese and Western tablets and pills, including the micro pills and granulated pills, small pills, water pills, drip and granulated pills, with sugar, organic film, water soluble, film, slow and controlled release film in the fields of pharmacy, food and biology etc. The machine is equipped with the programmable PLC(machine and person interface), with which its operation process and process parameters such as negative pressure and temperature can be automatically controlled. It's easy to operate, with reasonable and advanced process during run of the machine. Main machine, cleaning system, hot air cabinet, exhaust cabinet and the thermostatic mixing drum are all made of imported high quality, stainless steel, which conforms to GMP requirements.
Basic working principle
The tablets make complicated and constant track movement with easy and smooth turning and frequent exchanging in a clean and closed drum of the film coating machine. The coating mediums stirred in the constant temperature-stirring drum are prayed on tablets through the spray gun at the inlet under the action of crawler pump. Meanwhile, the hot air up to 100, 000 level filtration is inhaled through the air-distributing pipe at the center of the drum and flowed through tablets around the fan blade. Under the action of air exhausted and negative pressure, hot air are exhausted from another side of the air-distributing pipe and discharged after dust abatement. So these coating mediums on the surface of tablets get dry quickly, forming a coat of film, fine and smooth film. Automatically controlled by PLC, it's in normal operation.
