1、 Technical principle and core functions of multifunctional coating machine

The multifunctional coating machine realizes the integrated processing of material mixing, granulation, drying and coating through the combination of fluidized bed technology and spray drying technology. Its working principle is divided into three steps:

• Fluidization treatment: The material is suspended under the action of hot air to form a uniform flow layer.

• spray coating: spray the coating solution evenly onto the surface of the material with the spray gun to form porous spherical particles or film layer.

Drying and curing: Continuous drying with hot air causes the coating layer to form a film, ultimately obtaining a product that meets the standards.

2、 Innovation in the application field of multifunctional coating machines

• Pharmaceutical industry: used for tablet sustained-release coating, capsule film coating preparation, to enhance drug stability and controlled release effect.

• Food industry: chocolate polishing, nut icing, and even the rolling of rice dumpling and pearl vermicelli.

Agriculture and Chemical Industry: Seed coating protective film can improve germination rate, while chemical fillers such as alumina ball coating enhance performance.

3、 The trend of intelligent development of multifunctional coating machines

Modern coating machines have integrated PLC control systems and variable frequency speed regulation technology to achieve stepless speed change and fully automated operation. For example:

• Accurate control: adjust the temperature, spray volume and other parameters through the touch screen to ensure uniform coating.

Clean design: Closed pot body and 300000 level purification air supply system to avoid cross contamination.

Energy saving and efficient: Complete multiple processes in one step, reducing production cycle by more than 50%.

4、 Future prospects of multifunctional coating machines

With the penetration of artificial intelligence and computer vision technology, coating machines will develop towards higher precision and lower energy consumption. Its "tailor like" precision processing ability will continue to drive the quality upgrade of industries such as pharmaceuticals and food.
