Ultrasonic Assisted Liquid Process for Herb Extract Equipment 

What's the theory of ultrasonic sonochemistry? 

The essence of the sonochemical effect is the cavitation effect, including the appearance of the gas nucleus, the growth of the microbubbles and the bursting of the microbubbles. Under the action of ultrasound, the fluid produces a sharp motion. Due to the change of sound pressure, the solvent is compressed and sparse. In the sparse phase region of the sound wave, the gas bubble expands and is filled with the surrounding liquid vapor or gas. In the compressed phase region, the air pockets quickly collapse and rupture, producing a large number of microbubbles, which in turn can serve as new gas cores. It is currently believed that the main reason for the influence of ultrasound on chemical reactions is that these microbubbles can generate strong shock waves when they grow up and suddenly rupture. It is estimated that when the microbubble bursts, it can generate pressures up to MPa in the local space, and the center temperature can reach 3000-5000K. The interpretation of the action of the ultrasonic field has not yet entered the molecular level, but stays in the machinery of the molecular group. The level of action mechanism. For example, the cavitation and cleansing effect on the solid surface; the emulsification of the immiscible liquid; the effect of the high temperature and high pressure caused by the shock wave in the micro space on mass transfer and energy transfer when the microbubble bursts.
