specification：

Ultrasound is an elastic mechanical vibration wave, which is essentially different from electromagnetic waves. Because electromagnetic waves propagate in vacuum, and ultrasonic waves must propagate in the medium. When passing through the medium, the whole process of expansion and compression is formed. In the liquid, the expansion process creates negative pressure. If the ultrasonic energy is strong enough, the expansion process will generate bubbles in the liquid or tear the liquid into tiny cavities. These cavities close instantaneously and produce an instantaneous pressure of up to 3000 MPa when they are closed, which is called cavitation. The entire process is completed within 400 us. 

Some related application cases of ultrasonic extraction equipment. 

Ultrasonic field enhanced oil extraction can significantly increase the extraction efficiency, improve the quality of the oil, save raw materials, and increase the amount of oil extracted. Ultrasonic field can not only intensify the extraction process of substances by conventional fluids, but also intensify the extraction process of substances in the supercritical state. In the process of ultrasonic-enhanced supercritical CO2 fluid extraction, wheat germ oil is extracted from malt germ. After supercritical fluid extraction with ultrasonic field, the extraction rate of wheat germ oil is increased by about 10% without causing degradation of wheat germ oil.

Ultrasonic extraction of protein also has a significant effect. Ultrasonic waves can not only crush the above-mentioned embryos in water, but also liquefy 80% of the proteins, and extract the thermally unstable 7S protein components. Ultrasonic treatment can increase the protein extraction rate; ultrasonic treatment can also increase the separation temperature of the slurry and reduce the viscosity of the slurry, which can be used to directly produce high-protein soy milk products. The soybean slurry of different concentrations, the heat-treated soybean slurry before grinding and the separated bean dregs are subjected to ultrasonic treatment. Compared with the untreated soybean slurry, the protein content of the soybean milk after ultrasonic treatment has been significantly increased, and the increase range is 12%-20%.

Compared with the traditional technology of ultrasonic polysaccharide extraction, the ultrasonic enhanced extraction operation is simple, the extraction rate is high, and there is no material loss and no side reactions during the reaction process. The extraction of polysaccharides from Flammulina velutipes fruiting bodies can be enhanced by ultrasound, which can increase the extraction rate of polysaccharides by 76.22%; the extraction rate of Tremella fuciformis polysaccharides with ultrasonic hot water extraction is 5% higher than that of enzymatic method, and the extraction time is greatly shortened. Ultrasound has a significant effect on the extraction rate. Ultrasound strengthens the supercritical fluid and extracts (SSFE) capsaicin from peppers. The results of ultrasonic extraction of valerian spice and the results of extraction without ultrasonic were compared. The absorbance of the filtrate and the absorbance of the filtrate using ultrasonic was 12%-40% higher than that of the filtrate without ultrasonic.

Compared with conventional extraction technology, ultrasonic extraction is fast, inexpensive and efficient. Compared with the water boiling and alcohol precipitation process, ultrasonic extraction has the following outstanding features: no need for high temperature and atmospheric pressure extraction, good safety, simple and easy operation, convenient maintenance, high extraction efficiency, and broad spectrum. Wide applicability, most of the various components of Chinese medicinal materials can be ultrasonically extracted. Ultrasonic extraction has a small relationship with the properties of the solvent and the target extract. It reduces energy consumption. Less impurities, easy separation of effective components, purification, ultrasonic extraction, low process cost, and significant comprehensive economic benefits
