Ultrasonic liquid processor is a mechanical process to reduce small particles in a liquid so that they become uniformly small and evenly distributed.

??

When ultrasonic processors are used as homogenizers, the objective is to reduce small particles in a liquid to improve uniformity and stability. These particles (disperse phase) can be either solids or liquids. A reduction in the mean diameter of the particles increases the number of individual particles. This leads to a reduction of the average particle distance and increases the particle surface area.

??

Ultrasonic liquid processors are used in a wide variety of applications including, but not limited to, nanoparticle preparation, cell lysis, emulsification of immiscible solution bodies, and dispersion of nanoparticles. These applications demonstrate the potential of ultrasonic technology in fields such as biomedicine, chemistry, and materials science.

Immiscible solution emulsification of ultrasonic liquid processor technology details mainly include the following aspects:

??

Emulsification principle: ultrasonic emulsification is the use of ultrasound in the liquid generated by high-frequency compression and dilution, through the ultrasonic waves into the liquid when the high intensity of the compression and shear effect, the formation of a large number of tiny droplets and bubbles. These droplets and bubbles are continuously compressed and expanded in the process of vibration, thus forming shear and shear force, making two incompatible liquids mix with each other and form emulsion.

??

Emulsification process: the process of mixing two (or more) incompatible liquids to form a dispersion system under the action of ultrasonic energy, where one liquid is uniformly distributed as a liquid in the other to form an emulsion.51 This process involves the ultrasonic cavitation effect, whereby a large number of bubbles are generated within the liquid under the action of strong ultrasonic waves, and the small bubbles will gradually break up with the ultrasonic vibrations, creating a localized high temperature and high pressure environment that contributes to the formation of an emulsion. A localized high-temperature and high-pressure environment is generated, which contributes to the mixing and emulsification of incompatible liquids.

??

Technical advantages: compared with the propeller, colloid, homogenizer and other conventional emulsification processes and equipment, ultrasonic emulsification has a good emulsification quality, the average droplet size of the emulsion is small, the droplet size is uniformly distributed, and the emulsion formed is more stable, and some of them are stable for a few months to more than half a year5356.

??

Application scope: ultrasonic liquid treatment equipment can be used for liquid dispersion, extraction, emulsification and homogenization and other functions, suitable for processing such as graphene, liposomes, coatings, alumina, silicon dioxide, nanomaterials, carbon nanotubes, carbon black and other dispersed substances, as well as the extraction of traditional Chinese medicine, CBD, proteins and so on.

??

The ultrasonic liquid processor technology for the emulsification of immiscible solutions relies mainly on the high-frequency compression and dilution effects generated by ultrasound to mix and emulsify two incompatible liquids through the formation of tiny droplets and bubbles as well as shear and shear forces. This technology has the advantages of good emulsification quality, high emulsion stability, and a wide range of applications.
