Customized Anti-Sticking Spray Drying System by Changhai

For high-sugar, high-extract and other sticky materials, we provide systematic solutions from both process and equipment dimensions:

1. Precise Temperature Control: We first test the glass transition temperature of the material, then accurately control the tower wall temperature at 5-10℃ below the material's softening point to prevent adhesion caused by material softening;

2. Patented Wall Air Protection System: An annular secondary cold air curtain is introduced on the tower wall to form an air curtain barrier, isolating droplets from direct contact with the tower wall;

3. Optimized Equipment Structure: The inner wall of the tower is treated with mirror polishing and anti-stick coating, combined with a rotary air-sweeping device to actively remove slightly adhered materials;

4. Full-Process Debugging: We optimize feed concentration, atomization pressure and hot air distribution according to material characteristics, increasing powder yield by over 15% and enabling stable production without adding auxiliary materials.
