Herb Extraction Machine is an industrial or laboratory equipment used to separate active ingredients (such as essential oils, flavonoids, polyphenols, etc.) from plant materials. Widely used in the production of traditional Chinese medicine, health products, cosmetics, and food additives. 

According to different extraction principles, herb extraction machine can be divided into multiple technical routes, each suitable for different raw materials and target products.

Extraction technology type of herb extraction machine
1) Ultrasonic extraction utilizes high-frequency vibration to destroy cell walls, promote solvent penetration, and extract herbs, flowers, leaves, and roots with high efficiency, low temperature, and retention of active ingredients. The equipment cost is relatively high
2) Steam distillation collects aromatic herbs (such as lavender) by condensing volatile components carried by steam. The mature process and simple operation are limited to volatile oils, and the thermosensitive components are easily destroyed
3) Solvent extraction, using solvents such as ethanol and water for soaking and extraction, can extract non-volatile substances (such as flavonoids) from most plant components. Subsequent concentration and solvent recovery vacuum extraction are required, supporting a water/alcohol dual system
