The color of the dried material is good and does not deteriorate, which greatly improves the economic benefits of the factory. Compared with LPG high-speed centrifugal spray drying, the Chinese medicine extract is compared with LPG high-speed centrifugal spray drying. Has the following characteristics:

1. Three-stage air purification is adopted to meet the requirements of 300,000 air intake.

2. The cold wall device is adopted to make the inner wall temperature reach 80 ° C, and the material stays on the wall and will not be coked.

3. The entire volume is 3.5 times that of the original LPG standard centrifugal spray.
