II、 Equipment Overview:

Vacuum rake dryer is a type of heat conduction drying equipment, also known as rake stirring dryer.

1. Good sealing performance and high vacuum degree

Adopting reasonable structural design and scientific and reasonable processing technology ensures the sealing effect of the static seal. By improving the sealing structure of the shaft end and scientifically selecting sealing materials, the sealing effect of the dynamic seal has been improved;

2. The equipment has a compact structure and simple operation;

3. Unique design of thermal medium flow channel with high thermal efficiency。

The mixing shaft and jacket are both designed with unique fluid channels, which can ensure that the fluid will not short-circuit and have no dead zones, strengthening the heat transfer between fluids, resulting in high thermal efficiency;

4. Dynamic sealing will not pollute materials

5. Mix thoroughly and achieve good drying effect

Due to the continuous stirring of the mixing shaft, the materials are stirred and mixed to a maximum extent, improving heat transfer between materials and increasing drying efficiency;

6. Electrochemical polishing of the surface in contact with the material

The surface roughness after electrochemical polishing can reach 0.1-0.05 μ M;
