Main Components
Rotating Coating Pan
Made of premium stainless steel, the coating pan features a sleek inner wall and stable rotational operation. Its optimized structural design keeps tablets tumbling evenly throughout the coating process, avoiding material accumulation and uneven coating results caused by concentrated stacking.
Spraying System
The supporting spraying unit distributes coating liquid evenly over rolling tablets. Operators can freely adjust spraying speed and atomization effect to match different coating formulas and on-site production demands, ensuring every single product gets full and uniform surface coverage.
Hot Air Drying System
Clean filtered hot air is delivered into the coating chamber to quickly evaporate surface moisture. Both air temperature and airflow are fully adjustable, maintaining steady and even drying conditions. This avoids flawed, uneven film layers triggered by unstable temperature changes during operation.
Drive System
Fitted with professional motors and reducers, the drive unit delivers consistent, stable pan rotation. Equipped with variable-speed control, it allows workers to adjust tablet tumbling intensity based on different product specifications, adapting to diverse coating processing requirements.
Control System
The independent control cabinet centrally manages all key operating parameters, including pan rotation speed, drying temperature and spraying volume. It simplifies daily operation and real-time process monitoring, keeping coating results stable and repeatable for every production batch.
Features
This pharmaceutical coating machine delivers even film coating with accurate, tunable thickness, ensuring consistent surface finishing across all batches. It works well with tablets, pills and granular products, and can adapt to different coating formulas and color customization needs. All parts that come into contact with materials adopt stainless steel construction, enabling easy thorough cleaning and compliant sanitary maintenance.
The fully enclosed coating chamber greatly reduces dust leakage and coating material waste, improving raw material utilization rates. Optimized tablet movement prevents product adhesion and surface damage, effectively lowering breakage rates. The machine supports both batch and continuous production. Users can also upgrade to automatic spraying, drying and cleaning systems to meet higher automated production standards.
Working Principle
After being loaded into the rotating coating pan, tablets continuously tumble and flip with the pan's movement. The precision spray gun outputs coating liquid stably, evenly covering the surface of moving products. Meanwhile, filtered constant-temperature hot air circulates inside the chamber to continuously remove surface moisture.
Repeated cycles of spraying, material mixing and drying gradually form smooth, dense and uniform protective films on tablet surfaces. Operators can fine-tune rotation speed, spray rate, drying temperature and airflow based on different formulas and product sizes, stabilizing batch quality for long-term standardized production.
Applications
This pharmaceutical coating machine is widely used for surface processing in pharmaceutical, health supplement and food industries. It handles common pharmaceutical tablets, sugar-coated and film-coated tablets, as well as herbal and nutritional tablets. It also supports sophisticated processing such as enteric coating, color coating and anti-corrosion protective coating.
Beyond pharmaceutical processing, the machine is applicable for surface coating of various food and confectionery products. It fulfills multiple processing functions, including surface protection, color modification, taste masking and custom functional film coating, covering most personalized and standardized coating needs in industrial production.
