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;
