Coating machines are a type of high-efficiency, energy-saving, safe, and clean electromechanical integrated equipment used for coating tablets, pills, candies, etc. with organic films, water-soluble films, and controlled-release coatings. They are suitable for pharmaceutical, chemical, and food industries. According to heat exchange efficiency, they can be divided into perforated and non-perforated coating machines, and according to production capacity, they can be divided into production type and experimental type.

Experimental high-efficiency coating machines have the capacity to coat 0.2kg to 13kg on the same machine . The equipment mainly consists of a main unit, a hot air cabinet, an exhaust cabinet, and a computer control system. The coating medium moves in the rotating drum through the action of the guide plate, automatically sprays the coating medium, and dries it into a film under the action of hot air. The control system mostly adopts PLC and touch screen operation . Continuous film coating technology is gradually replacing the traditional intermittent process.High-efficiency intelligent coating machines adopt advanced control systems and manufacturing processes.
