Ultrasonic extractor is the ultrasonic dispersing device is an application of acoustic chemical equipment, can be used for water treatment, solid dispersion of particles in a liquid system, disaggregation, promoting effect of solid-liquid reaction etc.It is called as emulsifying/nebulier/homogonizer too.

 

Features:

Ultrasonic-assisted extraction is fast, inexpensive, and efficient compared to conventional extraction techniques. Ultrasonic extraction has the following outstanding features compared to boiling and alcohol precipitation:

(1) No need for high temperature

(2) Atmospheric pressure extraction, good safety, easy operation, easy maintenance

(3) High extraction efficiency

(4) It has broad spectrum. Wide applicability, most of the ingredients of Chinese herbal medicine can be ultrasonically extracted

(5) Ultrasonic extraction has little relationship between the solvent and the target extract

(6) Reduce energy consumption

(7) The raw material of the medicinal materials is processed in large quantities, which is multiplied or multiplied, and the impurities are small, and the active ingredients are easy to be separated and purified.

(8) Low extraction process cost and significant comprehensive economic benefits

 

Application:

The application in nicotine extraction, the application in the extraction of Lycium barbarum polysaccharide, the application in the extraction of lycopene, the application in the extraction of total flavonoids from lotus seeds, the application in oil leaching, the application in protein extraction, Application in polysaccharide extraction, in food analysis.

 

FAQ:

Q: What’s the working principle of ultrasonic extraction?

A: Ultrasonic waves are elastic mechanical vibration waves that are essentially different from electromagnetic waves. Because electromagnetic waves propagate in a vacuum, ultrasonic waves must propagate through the medium, forming a whole process of expansion and compression as it passes through the medium.

In the liquid, the expansion process creates a negative pressure. If the ultrasonic energy is strong enough, the expansion process creates bubbles in the liquid or tears the liquid into small holes. These cavities are momentarily closed, and when closed, an instantaneous pressure of up to 3000 MPa is generated, which is called cavitation, and the whole process is completed in 400 μs.

The cavitation refines the substance and manufactures the emulsion, accelerates the entry of the target component into the solvent, and increases the extraction rate. In addition to cavitation, many secondary effects of ultrasound are also beneficial for the transfer and extraction of target components.

The significance of the phenomenon of cavitation is the reaction that occurs when the bubble bursts. At some point, the bubble no longer absorbs the ultrasonic energy and creates an implosion. Gases and vapors in bubbles or holes are rapidly adiabatically compressed, producing extremely high temperatures and pressures.
