Performance and Characteristics:
1. The coating boiler equipped in the high pressure spray gun, there set a cleaning sprayer at the air exhaust exit and hot air mouth, which can be rotated in automatic and full direction ,without dead corner more convenient to clean. (Option)
2. Select the imported spray gun. It's convenient to operate and easy to master and flexible controlled technological requirement. The spray gun head requirement must keep in the range of 0.29 Mpa to 0.39 Mpa. Angle and sector can be adjustable , uniform density and particle in spray pressure and 0.4-0.5Mpa in atomization pressure that avoid the dropping leakage and blockage phenomenon of size, uniform atomization and large spray area, practical to adjust flow, free leakage and blockage, angle and sector.
3. Film coating machine contains the mechanical device of cauldron wrapping little material can coat at least 20~40kg plain pills in 150 type coating machine, regulate through it inherent machinery, make a small mount of medium coat in cauldron and will not cause the wasted of dressing and greatly improve the scope of appliance.
Filtration Hot Air Cabinet
Firstly, air inhaled in through the centrifugal fan should be purified up to the 100,000 Level after three times filtration, involving primary filtration, medium filtration and high filtration, then be blown to the drum of main machine through the (steam or electrothermal) .Equipped with a vibration damper. Equipped with primary filtration device in the air inlet.
Air Exhaust Cabinet
Used for exhausting air out of drum in the major machine ( including dust absorption), keeping the working area under negative pressure. Equipped with a vibration damper. The exhaust outlet is equipped with a reflux-proof device. Close the exhaust cutlet before stop the machine to prevent the air in the exhaust cabinet from reflux. It is equipped with dust abatemert & filtration by vibration. so the vibration and dust are insulated, the dust is stopped from fly off and the dust abatement is automatically separated, which makes easy.
Agitating and Holding Tank (Electric-Heating)
Thermal stirring drum adopts electric heating type. It is equipped with pneumatic stirrer which is driven by compressed air, stable rotating speed and stepless speed regulating, medium can be stirred homogeneous. It can be controlled automatically at normal temperature to 80°C, easy-operating, safe and reliable. All parts are made of stainless steel, inside and outside is mirror polished.
Basic Working Principle:
The tablets in drum make complicated and constant track movement with easy and smooth turn frequent exchanging in a clean and closed drum of the film coating machine. The coating mixed round in the mixing drum are sprayed on tablets through the spray gun at the Inlet un action of the peristaltic pump. Meanwhile under the action of air exhaust and negative pressure 100,000 clean hot air supplied by the air exhaust cabinet is exhausted from the fan at the sieve meshes through tablets. So these coating mediums on the surface of tablets get dry forming a coat of firm, fine and smooth film. The whole process is finished under the control of PLC.
