Features

1.  Drying speed is fast. Material is atomized and superficial area is increased greatly. During contacting with hot air, 95%~89% moisture will be evaporated instantly. Drying time just need seconds, so it is suitable for drying thermal sensitive materials.

2.  The product has good degree of homogeneity, fluidity and solubility

3.  Production process is simple and operation is easy to control. Liquid can be dried to powder product one time, and after dried crushing and sieving is not needed, so the production steps are reduced. The particle size, density, moisture content of product can be adjusted and controlled by changing operation condition.

4.  Adopts mechanical type centrifugal atomizer, driven by gear, rotary speed is stable and can ensure the uniform distribution of forgdrops

5.  The direction and angle of hot air distributor adopt adjustable structure, it can ensure the forgdrop contact with hot air fully.

6. Elbow is made of sanitation degree steel pipe, it can avoid the material blocked in the elbow.
