The solution to the problem of sticking walls in high-speed centrifugal spray dryers:
First, the road to cure the symptoms - Yang Tang boiling method:
1. Viscous wall formed by high humidity material: the droplet sprayed by the high-speed centrifugal spray dryer has been in contact with the wall without ensuring that the outside has been dried;
Solution: Check the plane of the motion track where the atomizer sprays the droplet, and always pay attention to the movement state of the atomizer and the tower wind.
2, the surface adhesion of dry powder: dry powder will always touch the wall due to movement;
The solution is to polish the inner wall and tap it lightly.
3. The sticky wall formed by the low melting point material: the material reaches the melting point and then melts and becomes sticky;
Solution: Select the material with high melting point and control the temperature.
Second, the root of the cure - the bottom of the pumping method:
1. Add a hammer device to the tower wall, always ready to hit the tower wall
2. Cooling through the tangential airflow of the tower wall to the secondary air
3. Improve the processing precision of high-speed centrifugal spray dryer, and regularly polish the inner wall of the tower.
4, using a wall drying tower, the air is cooled in the middle to maintain a constant temperature of the wall temperature below 50 ° C
5. Install a row of nozzle type air broom near the wall of the tower to carry out cleaning work.
If you encounter problems and think about solutions in a multi-faceted way, you can make progress. This high-speed centrifugal spray dryer can sit back and relax.
