Biologically, chemically and pharmaceutically active agents are often derived from natural sources in liquid form. This is particularly the case with plant extracts. 70% of our customers adopt vacuum belt dryer for herbal extract drying process.

 

Extracts from plant parts and plant preparations are widely employed in many industries, including  the feed, food, functional food, nutraceutical, dietary supplement and pharmaceutical industries.

Vacuum belt drying is very important method for dehydrating or drying fluids, fluid foods and botanical extracts. 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, 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.
