Basic Working Principle:

The tablets make complicated and constant track movement with easy and smoothturning and frequent exchanging in a clean and closed drum of the film coating machineThe coating mediums stirred in the constant temperature controlled stirring drum aresprayed on tablets through the spray gun at the inlet under the action of crawler pump.Meanwhile hot air up to 100,000 level filtration are inhaled through the air distributingpipe at the centerof the drum and flowed through tablets around the fan blade. Underthe action of air exhaustand negative pressure, hot air are exhausted from the anotherside of the air distributing pipe and discharged after dust abatement. So these coatingmediums on the surface of tablets get dry quickly, forming a coat of firm, fine andsmooth film. Automatically controlled by PLC, it is in normal operation.
