High Frequency Food: Better Cutting With Ultrasonics
1 min read
Summary
To make the perfect slice, sometimes you need a little ultrasonic assistance, according to this article in Core77.
Cake, cheese and even bread can be difficult to slice without leaving marks, and production lines in the processed food industry need a consistently flawless finish to maintain speed.
Ultrasonic cutting works by using a sonotrode (an ultrasonic blade) to vibrate at frequencies in the region of 20kHz to 40kHz.
This vibration prevents the blade from becoming stuck in the food product as it slices, creating a clean-cut finish.
While mostly used in manufacturing, the technology is also available in smaller, handheld sizes for home use.
The technique also has applications in cutting rubber, textiles and plastics, with the heat generated by the sonotrode sometimes even sealing the edges of the material as it cuts.
