1.
Material requirements: Priority should be given to using materials with high hardness, corrosion resistance, and compatibility with ultrasonic frequencies (such as titanium alloy, special stainless steel, or coated blades).
2.
Coating technology: Consider using diamond coating or ceramic coating to reduce friction loss and food residue adhesion.
3.
Frequency and amplitude: Ensure that the parameters of the ultrasonic generator (such as frequency 20kHz~40kHz) match the blade design to avoid fatigue fracture caused by excessive amplitude.
4.
Cutting speed and pressure: Adjust the feed speed according to the characteristics of the food, such as hardness and viscosity, to avoid blade overload or friction overheating.
5. Avoid no-load operation: Ultrasonic knives are prone to resonance damage when unloaded. Before starting up, ensure that the blade contacts the material.
