In the pharmaceutical industry, tablet coating is a key process for improving drug stability, enhancing appearance, and controlling release.The BGZ series fully automatic coating machine, as the core equipment of modern coating technology, achieves high efficiency, stability, and safety in the coating process through highly automated and precise control technology, becoming an important tool for pharmaceutical companies to improve production quality and efficiency.

　　1、 Core functional features

1. Fully automated operation: The BGZ series adopts a PLC control system and a touch screen human-machine interface, which can preset coating parameters and achieve full process automation from feeding, coating to discharging. The device supports formula storage function, which can quickly switch between different types of coating processes, reduce manual intervention, and minimize operational errors.

2. Precise coating control: Equipped with an efficient spray gun system, the spraying amount of coating solution is accurately controlled through a peristaltic pump or pneumatic pump to ensure uniform coating on the surface of the tablet. The hot air circulation system adopts multi-stage temperature control technology, combined with the design of the uniform air plate inside the drum, to evenly distribute the hot air and improve the drying efficiency by more than 30%.

3. Efficient production and energy saving: The drum adopts a stepless speed regulating motor, which can adapt to the coating requirements of different specifications of tablets. The continuous production capacity of the equipment reaches 50-100kg/hour, which is 50% more efficient than traditional coating machines. Meanwhile, by optimizing the hot air circulation path, energy consumption has been reduced by 20%, which is in line with the concept of green pharmaceuticals.

　　2、 Structural design and material advantages

1. Modular design: The equipment consists of a coating roller, a spray gun system, a hot air circulation device, a dust removal system, and a control system. Each module operates independently and cooperates with each other. The drum is made of 304 stainless steel material, with polished inner walls (Ra ≤ 0.4 μ m) to prevent tablet wear or adhesion; The spray gun can be quickly disassembled and cleaned, meeting the requirements of GMP sterile production.

2. Safety and Environmental Protection: Equipped with explosion-proof motors and overload protection devices to ensure the safe operation of solvent based coating liquids; The dust removal system recovers dust through high-efficiency particulate air (HEPA) filters, reducing material loss and environmental pollution. Sealed design prevents powder overflow and meets the production standards of clean workshops.

　　3、 Application value and advantages

The BGZ series fully automatic coating machine is widely used in the coating production of chemical drugs, traditional Chinese medicine tablets, sustained-release formulations, and health products. Its precise process control can significantly improve the uniformity of coating, reduce defects such as cracking and flower spots; Automated operations reduce labor costs and are particularly suitable for large-scale continuous production. In addition, the device supports online cleaning (CIP) function, which shortens the switching time between batches and improves overall production efficiency.

The BGZ series fully automatic coating machine redefines the standards of modern pharmaceutical coating technology through intelligent, precise, and efficient design. Its reliable performance and flexible adaptability not only meet the high standard requirements of drug production, but also provide pharmaceutical companies with more competitive production solutions.
