The high-efficiency coating machine is applied in the fields of pharmaceuticals, food, biological products, etc. It can package various organic films, water-soluble films (which can achieve slow and controlled release effects in drugs) and sugar coatings for various tablets, pills, candies, etc. It has the advantages of beautiful appearance, high efficiency, low energy consumption, and small footprint. The coating process has no dust scattering or slurry splashing, improving the working environment and minimizing cross contamination of tablets; The tablet coating process is simple, significantly reducing the coating time and improving production efficiency. Adopting a new type of microcomputer temperature and negative pressure module control system, touch screen graphic display and control, with programmable functions, it can automatically adjust most of the process parameters such as flow rate, negative pressure, inlet air volume, exhaust air volume, temperature, speed, etc.,
