The physical mechanism of crushing insoluble solids (or liquids) is believed to be ultrasonic cavitation. Ultrasonic cavitation effect refers to the generation of a large number of bubbles in a liquid under the action of strong ultrasound. Small bubbles will gradually grow and increase with ultrasonic vibration, then suddenly burst and split, and the split bubbles will continue to grow and burst. When these small bubbles collapse rapidly, they generate high temperature and pressure inside the bubbles, and strong local shock waves are generated in the liquid near the bubbles due to the high-speed impact of the liquid around the bubbles, which also forms local high temperature and pressure, resulting in ultrasonic crushing and emulsification.

In the pharmaceutical and daily necessities industries, ultrasonic emulsification is commonly used to manufacture various emulsion products, such as emulsion drugs, cosmetics, and shoe polish. Ultrasonic emulsification can also be used to produce emulsified combustibles of oil (gasoline, diesel, etc.) with water or coal powder, in order to improve the combustion value per unit of fuel.

This technology has now been promoted and used within a limited range, with significant economic benefits. In order to reduce costs and adapt to large-scale production, mechanical ultrasonic transducer such as reed whistles are mostly used in ultrasonic emulsification. For liquids that are difficult to emulsify or for other special considerations, piezoelectric ultrasonic transducers are sometimes used in conjunction with appropriate sound focusing systems to increase sound intensity.

The average droplet size of lotion formed by ultrasonic emulsification is small, which can be 0.2~2um; The distribution range of droplet size is narrow, which can be between 01-10um or narrower.

The concentration of ultrasonic emulsion is high, the concentration of pure lotion can exceed 30%, and the added emulsifier can reach 70%.

The formed lotion is more stable. An important feature of ultrasonic emulsification is that it can produce extremely stable lotion without or with less emulsifiers.

You can control the type of lotion. With ultrasonic emulsification, both O/W (oil in water) and W/O (water in oil) lotion can be prepared under certain sound field conditions; However, it is impossible to use mechanical emulsification method. Only the nature of emulsifier can control the type of lotion.

When toluene is emulsified in water, one type of lotion can be formed under low sound intensity conditions, while another type of lotion can be formed under high sound intensity conditions.

The power required for ultrasonic emulsification to produce milk residue is small.
