Ultrasonic Cavitation Emulsion
Jan 22, 2019

A wide variety of intermediates and consumer products such as cosmetics, lotions, ointments, varnishes, paints, lubricants and fuels are mostly emulsions. In the laboratory, phacoemulsification capabilities have been widely used. Large ultrasonic liquid processor manufactured by HCSONIC for high-volume, high-efficiency emulsification in industrial production.

A system of up to 3,000 watts of ultrasonic processor provides the ability to convert this laboratory application into efficient industrial production, with continuous flow or batch dispersion of the emulsion, achieving results comparable to the best high pressures available today Quality, such as the new orifice valve. In addition to continuous and efficient emulsification, Hcsonic ultrasonic equipment has very low maintenance costs and is easy to handle and clean. The ultrasonic itself also supports cleaning and rinsing. Ultrasonic power is adjustable to suit specific product and emulsification requirements.

An emulsion is a dispersion of two or more immiscible liquids. High intensity ultrasound provides the second phase (continuous phase) in which the liquid phase (dispersion phase) is dispersed in small droplets to provide the required energy. In the dispersion zone, cavitation bubbles cause a sharp shock wave of the surrounding liquid, forming a high velocity liquid jet.

In order to stabilize the anti-agglomeration of the newly formed dispersed phase droplets, an emulsifier (surfactant) and a stabilizing substance are added to the emulsion. Since the coalescence of the droplets after the crushing affects the final droplet size distribution, an effective and stable emulsifier is used for maintaining the final particle size distribution of the droplets at a level equal to the distribution level after the droplets are broken in the ultrasonic dispersion zone. Stabilizers actually improve droplet breakage at a constant energy density.

In oils, studies in water (aqueous) and oil (oil phase) emulsions have shown a correlation between energy density and droplet size. When the energy density is increased, the size of the water droplets becomes significantly smaller. At appropriate energy density levels, ultrasound can well achieve an average droplet size of less than 1 micron (microemulsion).
