The entire unit is constructed from stainless steel with mirror-polished inner and outer surfaces.
The Filter Cartridge Type Exhaust Cabinet is designed for efficient dust extraction and ventilation of the main coating drum while maintaining negative pressure in the working area. Featuring a filter cartridge structure with compressed air pulse cleaning, it achieves a filtration grade up to F9 (with options for H13 upon request) and includes a damping device. The exhaust outlet is equipped with an anti-backflow device to prevent exhaust gas from flowing back into the pipeline when shut down.
The Surface Cooling Type Hot Air Cabinet is an advanced air treatment and supply unit designed specifically for high-efficiency pharmaceutical coating systems. Operating via a centrifugal blower, air passes through primary, medium, and surface-cooling dehumidification stages, followed by a high-efficiency filter to achieve Class 100,000 clean air standards while effectively removing moisture. The dried, purified air is then heated via a heat exchanger (steam or electric) and delivered into the main coating drum, equipped with built-in damping devices for stable, low-noise operation.
CIP Cleaning System Working Principle: Tablet cores move continuously along complex trajectories within the clean, sealed, rotating drum of the coating machine, ensuring smooth tumbling and frequent turnover. Coating medium—agitated in a constant-temperature mixing tank—is pumped to spray guns and applied onto the tablet cores. Simultaneously, under the influence of hot air and negative pressure, Class 100,000 clean hot air supplied by the hot air unit passes through the tablet bed, exits via the bottom screen perforations, and is discharged through the exhaust damper. This process rapidly dries the coating medium on the tablet surfaces, forming a solid, dense, and
Advanced PLC and HMI systems enable automatic parameter setting, recipe management and real-time data recording. Operators can reproduce proven coating machine processes at the touch of a button, reducing human error, saving materials and improving overall equipment effectiveness (OEE).
