In the early of 1970's, it has begun to introduce ultrasonic technology to food portioning. Today, it is capable to apply ultrasonic to cut cakes, pies, cheese, bread, and candy so on; the cut surface is fine and clean. While processing nuts or raisins with ultrasonic equipments, there is less damage caused then traditional cutting tools. Ultrasonic cutting is more suitable for crisp, creamy or soft foods. It has no deformation of products and makes extreme thin slices. Clean cutting is ensured and the phenomenon of attaching is almost negligible. Fast and clean cutting promotes higher capacity and shorter cleaning time.
While cutting foods, the ultrasonic cutting horn is oscillated in frequency of 20kHz or 35kHz and ensure food is not attached to the surface of cutting horn. The section of food is clean and layers kept clean. Recent studies have found that 35kHz cutting horn has the best performance of cutting hot and sticky foods; and no noise is occurred during processing. The time spent on routine cleaning is shorten; about 70%~90% lesser than traditional cutting equipments. For customers with traditional cutting equipments, it only needs small scale alternation to introduce ultrasonic cutting equipments into present system.
