Ultrasonic Emulsifying Equipment

Emulsions are dispersions of two or more immiscible liquids. Highly intensive ultrasound supplies the power needed to disperse a liquid phase (dispersed phase) in small droplets in a second phase (continuous phase). In the dispersing zone, imploding cavitation bubbles cause intensive shock waves in the surrounding liquid and result in the formation of liquid jets of high liquid velocity. In order to stabilize the newly formed droplets of the disperse phase against coalescence, emulsifiers (surface active substances, surfactants) and stabilizers are added to the emulsion.

Emulsification has many advantages over typical emulsification processes and equipment such as propeller, colloid mill and homogenizer.

The emulsion formed by ultrasonic emulsification has an average droplet size of 0.2 to 2 μm and a narrow droplet size distribution range of 01 to 10 μm or narrower.

High concentration of ultrasonic milk, pure emulsion concentration of more than 30%, plus up to 70% emulsifier.

Emulsion formed more stable, an important feature of emulsification is the emulsifier can be used less or less to produce a very stable emulsion.

Ultrasonic emulsification equipment required to produce small milk power.
