Vacuum belt dryer is a continuous infeed and discharge vacuum drying equipment. product is conveyed into dryer body by infeed pump, evenly spread on belts by distribution device. Under high vacuum, the boiling point of the is lowered; water in the 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.  

 Vacuum belt dryer turn traditional static drying to vacuum dynamic drying, reduce drying time from 10-20 hours to 30-60 minutes. In vacuum belt dryer, the drying temperature is adjustable for different products. It solves the high temperature problem with spray dryer and denaturation problem due to long drying time with traditional drying oven. Color, solubility, ingredients preservation of the dry product from vacuum belt dryer are incomparable.
