Detailed Product Description:
      Vacuum belt dryer is a continuous infeed and discharge vacuum drying equipment. Liquid product is conveyed into dryer body by infeed pump, evenly spread on belts by distribution device. Under high vacuum, the boiling point of the liquid is lowered; water in the liquid material is evaporated. Belts move on the heating plates evenly. Steam, hot water, hot oil can be used as heating media. With the moving of the belts, the product goes through from the beginning evaporating, drying, cooling to discharging in the end. The temperature decreases through this process, and can be adjusted for different products. Special vacuum crusher is equipped at the discharge end to produce different size end product. The dry powder or granule product can be automatically packed or continue with subsequent process.
 
Equipment Advantage:
1. With functions of automatic batching, automatic feed, the feed rate is adjustable, the final concentration ointment density can reach to 1.3 and solid-liquid mixtures.

2. With vacuum degree on-line automatic adjustment function, dynamic vacuum degree can be arbitrarily set in the range 1000 ~ 5000 pa.

3. Have function of Online automatically adjust the heating temperature, the heating temperature can be set in the range of 40 ~ 135 ℃.

4. With continuous feeding and continuous discharge, Online crushing and grinding function, crushing level count up to 100 mesh.

5. Conveyor belt automatic online correction function, speed adjustable, drying time is up to 72 hours continuously.

6. The whole drying process realizes the pipe-lining and completely isolated from the external environment, to avoid heat pollution.

7. The whole drying process realizes automation control, reduce the labor costs, all process parameters have reversible search.

8. Use hot water closed-circuit circulation heating technology, greatly reduce the energy consumption, is only 1/5compare with the spray drier.

9. Equipped with a full set of online automatic cleaning system, can cleaning and drying of equipment fast and test the cleaning effect.

APPLICATION SCOPE:

     Vacuum belt dryer (VBD) for liquid&paste is mainly used in drying many kinds of liquid or paste raw material, such as traditional & western medicines, food, biological products, chemical material, health foods, food additive etc, especially suitable for drying material with high-viscosity, easy agglomeration, or thermoplastic, thermal sensitivity, or material that can not be dried by traditional dryer.

For above materials, VBD is the best choice:

Pharmaceutical industry:chinese medicine extract, plant extract, egg embryo, PVPK series, fermenting liquid etc

Food industry:malt extract, carbohydrate, instant beverage, tea powder, cocoa powder, corn paste etc Chemical Industry:lithium battery, emamectin benzoate etc
