Food Cutting By Ultrasound

Not only non-woven and textile fabrics, but also various foods can be precisely and cleanly separated or cut by ultrasound.

Depending on application, cutting can be performed vertically, horizontally or continuously with the appropriate sonotrode design. Sonotrodes used as cutting tools suffer comparatively low wear. Because they are cold, as in the case of ultrasonic welding and punching, a wide variety of materials can be efficiently processed. Examples of this in the food industry are various types of cheese, bakery products and confectionery, dough or deep frozen products. The respective sonotrodes divide the food precisely with the help of ultrasonic oscillations. Cutting itself is due to the reduced force required by the vibration of the cutting tool easier than with conventional knives. The foods are therefore not deformed by compression or squashing.
