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 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.
Machine features:
- PLC and temperature module controlling system with the touch screen produced by Siemens Germany are applied to provide picture displaying, convenient operation, energy-efficiency, cleanliness and safety, and convenient cleaning, which meets the standard of GMP.
- Components, which drugs are exposed to, such as high efficiency film coating mainframe, high efficiency hot air filter, dust removal fan and spray device, are all made of imported stainless steel of good quality.
- The procedures are all controlled by PLC touch screen, automatically or manually.
- Coating is processed in totally closed environment to prevent dust and slurry from spilling. The surface of box is polished and its light pollution is eliminated.
- The driver system applies explosion-proof decelerating motor and chain-wheel transmission device, which can make frequency conversion continuously variable.
- High efficiency hot air filter can directly capture air from outside, heat the air after primary, intermediated and high efficiency filter, and then provide the air for the mainframe. The air can meet the standard of 100,000 class cleanliness. Dust removal fan can exhaust air to the outside to avoid the influence on central air-conditioning and to save energy.
- The spray gun is imported from Japan of good atomization, non-clogging nozzle, adjustable spray volume and angle, and simple structure which is convenient to clean.
- Spray guns for film and sugar coatings mounted independently on the multifunctional spray gun holder. Lighting for illuminating the pan interior for monitoring.
- Automatically adjustable multifunctional spray gun holder system for various coating purposes.
- Easy cleaning of the spray guns thanks to the built-in solution and air passages in the multifunctional spray gun holder system.
- Attachment detachment of the exhaust air chamber can be done with single operation for easier cleaning confirmation.
- Product can be discharged by reversing the rotation of the pan without additional operation.
- Newly developed process air chamber for fully perforated pan.
- Process air chamber efficiently diminishes heating of the coating pan.
- Built-in solution and atomization air passages within multifunctional spray gun holder system.
- Multifunctional spray gun holder enables an automatic positioning of the spray guns during the coating process for accurate coating of the tablet and saves coating material.
- Decelerated inlet air through the process air chamber prevents process air turbulence.
- Pan enclosure turns to washing basin during system cleaning.
- Addition of cooling mist device for optimum sugar coating of tablet.
- Multifunctional spray gun holder maintains the distance between the spray guns and tablet bed during sugar coating process.
- Process air smoothly goes through the pan without pulsation.
- The three-dimensional fully perforated baffle system.
- Cooling of the pan with dry mist prevents adhesion of the tablets on the pan and reduces the occurrence of convexes of tablets.
- Multifunctional spray gun holder enables a continuous sugar coating process from protective to sugar coating phases.
- Multifunctional spray gun holder can be easily removed from the pan for easy change, cleaning and inspection of the spray gun units.
- Washing of both inside and outside of the pan can be done quickly with filled water by our large cleaning sink.
