The working principle and wide application of highly sealed and efficient coating machine
Date: 2025-09-02Read: 6
The highly sealed and efficient coating machine is an electromechanical integrated equipment that meets GMP requirements, mainly used for the coating process of pharmaceutical preparations (such as tablets, pills, microspheres, etc.). Its core working principle and characteristics are as follows:
1、 Working principle
1. Dynamic coating process: Su Rui (pellets, tablets, etc.) is guided by a streamlined guide plate in a closed rotating drum, forming a complex trajectory motion.
2. Medium spraying and drying: The coating medium (such as sugar coating, film coating, etc.) is automatically sprayed through the PLC control system, and the negative pressure hot air system introduces clean hot air from the center of the drum, penetrates the core layer, and is discharged to achieve fast and uniform drying.
3. Film formation: The dried coating medium forms a strong, dense, and smooth film on the surface of the core, enhancing the stability and shelf life of the drug.
2、 Technical features
1. High airtightness: The fully enclosed design combined with negative pressure system prevents cross contamination and meets the production requirements of highly active agents.
2. Intelligent control: adopting PLC+HMI system, supporting process parameter programming, adapting to different coating requirements.
3. Efficient and energy-saving: Integrating 3D dynamic mixing, intelligent spray gun adjustment, and millisecond level temperature control technology to optimize coating efficiency.
3、 Application scope
1. Pharmaceutical field: Chinese and Western pill formulations, pills, sustained-release preparations, etc., used for sugar coating and organic/water-soluble film coating.
2. Food industry: surface coating of candy, chocolate and other products.
3. Highly active agents: Combined with isolator technology, achieve a highly enclosed production environment and ensure operational safety.
This equipment significantly improves the quality of coating and production safety through automation and sealed design, becoming a key process equipment in the pharmaceutical and food industries.
