Vacuum belt dryer is mainly used in drying many kinds of liquid or paste raw material,such as Traditional& Western medicine, food, biological product, chemical not be dried by traditional dryer.For above materials, vacuum belt dryer is the best choice.
Pharmaceutical industry: Chinese medicine extract, plant extract, egg embryo, PVPK series, fermenting liquid ..
Chemical industry:lithium battery, emamectin benzoate etc.
Vacuum belt dryer is a continuous infeed and discharge vacuum drying machine .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 products goes through from the begining evaporating, drying, cooling to discharge 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 of granule product can be automatically packed or continue with subsequent process.
Vacuum belt dryer turn traditional static dryer to vacuum drying, reduce drying time from 10-20hours to 30-60minutes. 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.
