High Power With High Frequency Ultrasound Sonicator For Herbs Extraction

Description: 

When high-power, low-frequency ultrasonic waves are coupled to a slurry composed of plant materials in a solvent, ultrasonic extraction can be achieved. High-power ultrasonic waves are coupled into the slurry through a probe-type ultrasonic processor. High-energy ultrasonic waves propagate in the liquid, generating high-pressure/low-pressure alternating cycles, resulting in acoustic cavitation. Acoustic cavitation or ultrasonic cavitation can locally cause extreme temperatures, pressures, heating/cooling rates, pressure differences, and high shear forces in the medium. When cavitation bubbles implode on the surface of solids (such as particles, plant cells, tissues, etc.), micro-jets and joint collisions produce effects such as surface peeling, erosion, particle rupture, acoustic perforation (perforation of cell walls and cell membranes), and cell rupture. . In addition, the implosion of cavitation bubbles in the liquid medium will produce macro-turbulence and micro-mixing. Ultrasonic irradiation is an effective method to enhance the mass transfer process, because the effect of ultrasound can cause cavitation and its related mechanisms, such as the microscopic movement of liquid jets, compression and decompression in materials, and subsequent destruction of cell walls, as well as high heating and Cooling rate. Probe-type ultrasonic generators can generate very high amplitudes, which are necessary to generate impact cavitation. SP-TECH produces high-performance ultrasonic extractors that can easily generate 100µm amplitude in continuous operation.

Advantages: 

1. Compared with the traditional mixing and ball milling process, the operation cost per unit capacity can be greatly reduced. It is especially suitable for industrial production.

2. For liquid-liquid mixture, the chemical reaction speed can be increased, the amount of additives can be reduced, and the fully mixed solution is not suitable for stratification for a long time.

3. For the solid-liquid mixture, the easily agglomerated nanoparticles can be opened in a short time, and the dispersed ultrafine particles are not easy to agglomerate again.
