Abstract
High-power ultrasound is being widely utilized for decontamination in different industrial applications. The same technology is also being investigated as an effective tool for cleaning of components in the decontamination of produce. An understanding of the basic technology and how it works in cleaning various industrial parts should help in applying it on a large scale in the food industry. The technology has evolved throughout the past four decades. Different frequencies were developed and are now industrially available. The frequency range is from 20 kHz to 1 MHz. Current sound technology provides a uniform ultrasonic activity throughout the cleaning vessel, which was a major disadvantage in the earlier technology. The two main driving forces that affect cleaning of surfaces are cavitation and acoustic streaming. Both are generated as a result of the direct interaction of high-frequency sound waves with fluids.
