Vacuum belt dryer is continuous in feed and discharge vacuum drying equipment. Liquid product is conveyed into dryer body by in feed 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, and 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. Colors, solubility, ingredients preservation of the dry product from vacuum belt dryer are incomparable.

Range of application :

Advantage :

• Bespoke engineered continuous drying solution to fit your requirements
• Continuous and gentle drying preserving maximum colour, flavour and composition， and minimal oxidation
• Individual temperature zones allow for product-specific profiles to be developed suited to each perfectly to each product
• Less energy used than other drying methods
• Viewing windows as standard allow for continuous monitoring, with options for automated monitoring systems available
• Product specific feeding and discharging systems
• Fully PLC automated operation & CIP cleaning system
• GMP standards

Equipment Specification :

If the solvent of raw material is organic (ethanol, acetone, methanol etc.),evaporation capacity would rise. Evaporation capacity is closely related with drying temperature
