Licorice, as a traditional Chinese medicinal herb, its active ingredients (such as glycyrrhizic acid) are easily decomposed at high temperatures. Therefore, after extraction, vacuum concentration technology needs to be used for solvent recovery and drug concentration to reduce boiling point and prevent component damage. 

This process of vacuum distillation concentration system of Licorice is commonly used in integrated production lines of extraction concentration drying
The vacuum concentration system or vacuum distillation concentration system used for licorice extraction mainly removes water and retains thermosensitive components through low-temperature vacuum evaporation. Common vacuum distillation concentration system includes single/multi effect evaporators, MVR systems, and external circulation vacuum concentrators, which are widely used in traditional Chinese medicine and food industries
