vacuum belt dryer

Product Description

Vacuum belt dryer is a continuous infeed and discharge cacuum drying equipment. Liquid product is conveyed into dryer body by infeed pump, evenly spread on belts by distribution device. Under high vaccum, 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 grnule 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 ****0 hours to ****0 nimutes. In vacuum belt dryer. the drying temperature is adjustable for different products. It soves 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.
