Why 20kHz is common for food cutting
Lower ultrasonic frequency can support larger sonotrodes and higher cutting loads. This makes 20kHz a practical choice for cake, cheese, frozen food, sandwiches and wide slicing applications.
Blade design considerations
Blade length, thickness, edge geometry, titanium material, mounting position and nodal support affect resonance and cutting quality. A blade should be designed together with the converter, booster and generator.
Maintenance and spare parts
Food cutting blades should be inspected for edge damage, loosened mounting, surface wear and cleaning damage. For automated lines, keeping tuned spare blades reduces downtime.
