The Importance of Coating Technology

Oral Solid Dosage (OSD) remains the predominant form of product, holding a dominant position. Coating is an indispensable component in the development of OSD formulations, as it serves multiple purposes such as enhancing stability, masking unpleasant odors, reducing irritability, delaying and controlling release, improving appearance, and facilitating ease of consumption.

Langger蠕动泵 products find extensive application on coating machines. Characterized by high flow precision and excellent flow stability, Langger蠕动 pumps ensure the stable transmission of coating fluid to the atomizer on coating machines. The coating fluid, once atomized, forms uniformly sized droplets that are evenly sprayed onto the core surface, thereby creating a uniformly dense film. For most formulations, the thickness and uniformity of the coating layer are critical quality attributes, making the reproducibility of the coating fluid's flow rate essential.

Case Study

The workshop demands a controlled process for the fluidized bed coating technique, ensuring uniform coating layers and a yield that meets requirements. Under hygienic and safe conditions, high-precision distribution of coating liquid is applied to the core surface of the tablets.

The Lang Team boasts extensive experience in industry applications such as circulating fluidized bed and coating machines. Tailoring to our clients' needs, we offer customized solutions.

By utilizing the stainless steel peristaltic pump YT600-1J, paired with 8 high-performance peristaltic pump heads YZ1515x, 8 channels can run synchronously with excellent flow consistency between channels, and flow deviation less than 3%. This solution has helped the client address the core issue of ensuring uniform droplet size in the coating process, receiving full recognition from the client.

In terms of maintenance and repair, due to its unique operating principle, Langg's peristaltic pumps ensure that the transmitted fluid only contacts the inner wall of the hose, effectively meeting the high hygiene standards required by the industry. Moreover, as hoses are consumables, replacing them is simple, resulting in low maintenance costs and significantly reducing downtime. Langg's peristaltic pumps are the ideal choice for coating applications.

Our蠕动泵 meets a variety of requirements from desktop applications to bulk production. It not only satisfies process demands but also supports integration with other process equipment.
