Understanding how ultrasonic food cutting works

This cutting technology enhances the cut quality and consistency, and can cleanly slice multi-textured food products without deformation.

Applying ultrasonic vibration to a cutting tool creates a nearly frictionless cutting surface and can slice a multitude of food products cleanly without smearing.

Ultrasonic food cutting uses high-frequency vibratory knives. Applying ultrasonic vibration to a cutting tool creates a nearly frictionless cutting surface and can slice a multitude of food products cleanly without smearing. 

Very thin slices are also possible due to the reduced resistance. Foods containing items such as vegetables, meats, nuts, berries and fruits can be cut without deformation or displacement of the internal product. The low friction condition also reduces product sticking to the cutting tools, resulting in more consistent cuts and less down time for cleaning. “Because of the advanced process control that is available in ultrasonic generators, cutting performance can be easily manipulated by simply adjusting the equipment parameters,” states Bill Aurand, packaging technology manager with Sonics & Materials, Inc. 

According to Aurand, ultrasonic food cutting systems are often used in the following applications: 

•  Cutting hard and soft cheeses, including products containing pieces of nuts and fruit
