Due to the absorption of microwave energy, the cell temperature rises rapidly, so that the internal pressure of cells beyond the expansion of the cell wall capacity, cell wall rupture, the free flow of active ingredients within the cell, the extraction of medium under low temperature conditions dissolved .

The purified yeast ions are removed by the fermentation of the extract obtained by extraction with water and organic solvent to achieve the purpose of purification. It is also found that the purified metal ions can be removed better. If the extractant is water and ethanol, Directly concentrated after fermentation, if the extract is acetone, then to remove acetone before fermentation.

It can operate continuously, thus greatly improves production efficiency and reduces labor intensity. Therefore, it is particularly suitable for mass extraction of herbal medicines. The adoption of ultrasonic wave extraction technology enables our continuous ultrasonic wave countercurrent extraction equipment production line to have a lot of advantages. First, the extracting time is obviously shortened. Second, low temperature is particularly suitable for extraction of thermally sensitive pharmaceutical ingredients. Third, impurity content and power consumption are greatly reduced, and extraction ratio is effectively improved. The countercurrent extraction method is used to reduce the amount of solvent and lighten workload of the following filtration, separation and concentration, thus reduces production cost.  The continuous ultrasonic wave countercurrent extraction equipment production line operates in airtight environment. This effectively reduces process loss and guarantees security.

Depending on the material composition, the extraction material is different, choose different types of resin.The physical structure (such as surface, aperture, etc.) work, different resins have different pertinence. This technique can reduce the dose, improve the intrinsic quality and level of the preparation. It reduces the moisture absorption of the product and can shorten the production cycle, the required equipment is simple, eliminating the need for standing sedimentation, concentration and other time-consuming processes. Save packaging, reduce costs.
