The application of ultrasound in the food industry
The application of ultrasound can cut cakes, pies, cheese, pizza, bread, candy and other foods, and the cutting surface is clean and smooth. When using ultrasonic equipment to cut foods like nuts or raisins, it can produce finer fragments than traditional cutting processes. Therefore, ultrasonic cutting of food has more advantages than traditional methods: the cutting surface is clean and flat, the cutting knife has a longer service life, and more importantly, it can reduce the time of production shutdown due to cleaning and maintenance.
When cutting food, the ultrasonic cutting knife vibrates at a frequency of 20 kHz (or 30/40 kHz) so that food residues will not remain on the knife surface. The surface of the food after cutting is very clean, and the separation between layers is kept very clear. The latest research shows that higher frequency (30 and 40 kHz) ultrasonic cutting knives have the best cutting effect on hot and viscous food, and there is no noise during the whole process.
The downtime of the ultrasonic cutting system due to routine cleaning and maintenance can be reduced by 70% to 90% compared to traditional equipment. If customers who use traditional cutting equipment want to use ultrasonic technology to process food, they only need to make small changes to the existing equipment; or introduce a new system design on the basis of the existing production design.
