What is the working principle of an efficient coating machine?

In the production of tablet products, it is often necessary to consider how to continuously improve product quality and market competitiveness under certain cost control. In addition to factors such as meeting the requirements of biological Pharmaceutics, good appearance and stable internal quality are common goals for most common tablet products. Especially for traditional Chinese medicine sugar coated tablet products, due to the complex composition and large dosage, the quality of the tablets is not satisfactory, often resulting in loosening and cracking. Most of the extract preparations are prone to moisture absorption, adhesion and disintegration, slow dissolution, and other problems, making it difficult to apply new excipients and modify dosage forms. In recent years, more and more tablet manufacturers have adopted film coating as one of the effective ways to improve the quality of tablet products. However, it was also found that some people still have a simple understanding of film coating, with high expectations or incorrect application, especially due to a lack of systematic understanding and application, which has not achieved the expected results.
The high-efficiency coating machine is an improvement on the previous foundation and has a wider range of uses. Its working principle is mainly that the pistil continuously moves in a complex trajectory under the action of a streamlined guide plate inside a clean and closed rotating drum. During the movement process, according to the process flow and reasonable process parameters, the coating medium is automatically sprayed, and hot air is supplied under negative pressure. The hot air is discharged from the bottom of the pistil layer through the pistil, making the coating medium sprayed on the surface of the pistil quickly Uniform drying forms a sturdy and smooth surface film.
Currently, in the pharmaceutical machinery industry, due to continuous technological innovation, the speed of product updates is accelerating. As a common equipment in the industry, the coating machine has achieved new breakthroughs with the development of technology.
Many medications have a very pungent and unpleasant odor, making it difficult for patients to take them. The main purpose of an efficient coating machine is to improve its appearance, facilitate identification, mask adverse odors, facilitate patient swallowing, reduce gastrointestinal reactions, control drug release, change drug release curves, and also prevent moisture, light, and air to increase drug stability. Compared with sugar coating, it has the characteristics of short production cycle, less material consumption, and strong moisture resistance. In the coating process, it can be divided into water-soluble coating process and organic solvent coating process according to different solvents.
Main use: Intelligent and efficient coating machine, using a new type of microcomputer PLC and temperature module control system, with touch screen graphic display, easy to operate, efficient and energy-saving, clean and safe, in compliance with GMP requirements, widely used in the pharmaceutical and food industries. It is an ideal coating equipment for water-soluble film coating and organic film coating of tablets, pills, candies, chocolate, etc.
