Working principle

    It is an innovation horizontal batch-type vacuum drier improved on the basis of absorbing technology of domestic rake drier. The moisture of wet material will be evaporated by heat transmission. The stirrer with grinding scraper will remove material on hot surface and move in the container to form cycle flow. The evaporated moisture will be drawn out by vacuum pump.

Operation procedure

Feature

1. Being installed stirrer in the machine, it makes raw material form the state of continuous circle inside the body, so heating uniformity of raw material is raised greatly.

2. Being installed stirrer in the machine, slurry and paste shape material can be dried easily.

3. Special design for discharging port, make better sealing and less material accumulation, discharge is easy.

4. There are two seal model, mechanical seal and packing seal. The design supply good seal and long life.

5. The special techniques of shaft and rake support high strength and concentric.

6. The medium in shaft and vibration adding equipment will be equipped by requirement

7. Use different filter form according to different material.

Adaptive material

The following materials are dried in the fields of medicine, food and chemical industry:
◎Apply to paste, paste, powder material;
◎For low temperature dry heat sensitive material;
◎Easily oxidized, explosive, strongly stimulated and highly toxic material;
◎Materials that require the recovery of organic solvents.

Technical specifications

Note: the evaporation of water is related to the characteristics of the material, the heat inlet air and the outlet temperature. When the outlet temperature is 90oC, the moisture evaporation curve is shown above (for selection reference), as the product continues to increase
