- Jan 05, 2020-

1. The parts in contact with the product must be easy to clean and sterilize;

2. There should be measures to prevent coke and prevent hot air from generating eddy currents and countercurrents;

3. Prevent air from carrying impurities into the product;

4. Equipped with temperature and pressure indicator recorder device, which is convenient for checking production operation;

5. Dust recovery device with high recovery rate;

6. The powder should be cooled quickly to improve the solubility and instant solubility;

7. Drying room temperature and exhaust air temperature should not exceed 100 ℃ to ensure safety and quality;

8. The thick milk droplets are in uniform contact with the hot air during spraying to improve thermal efficiency;

9. Minimize sticking to viscous substances.
