ultrasonic extraction equipment

1. Mechanical stirring. Ultrasonic high frequency vibration and radiation pressure can form effective stirring and flow in gas and liquid. The strong jet and local microflushing generated by the cavitation bubble vibration on the solid surface can significantly reduce the surface tension and friction of the liquid, and destroy the surface layer of the solid-liquid interface, so as to reach a level that cannot be reached by ordinary low-frequency mechanical agitation. The effect. This action is the physical basis for the penetration of drugs, the penetration of beauty products into the skin, ultrasonic degassing, and the leveling and refinement of food and cosmetics.

2. Mutual diffusion. The pressure and high temperature effects of ultrasonic vibration and cavitation are used to facilitate the mutual penetration of molecules between two liquids, two solids, or liquid-solid-liquid-gas interfaces to form new material properties. Ultrasonic welding, phacoemulsification, cleaning and atomization of metals or plastics can all be classified as such effects.

3. Homogenization. The local shock generated after the cavitation bubble is closed can crush the particles in the liquid and make them thin. Make the crystal uniform; Dispersing large and uneven emulsion droplets into small and uniform drugs (such as medical contrast agents, cancer treatment agents, etc.); It may even involve thrombus dissolution.

4. Cohesion. Ultrasonic vibration can make the suspended particles in the gas-liquid medium move at different speeds and increase the chance of collision. Or a standing wave can be used to make them tend to the ridge point, and the polymerization process can take place. Flue dust collection and cloud seeding fall into this category.

5. Mechanical cutting effect. Due to the high acceleration of ultrasonic vibration and the acoustic corrosion of cavitation, special precision machining can be carried out on hard and brittle materials (jewelry, ceramics, glass, magnetic steel, etc.).

6. Mechanical crushing effect. The use of high-intensity ultrasound pulses can shatter kidney and gallstones in the human body without damaging soft tissue.
