Factors To Consider in The Process Of Cutting Food
Aug 04, 2022
1. Initial vibration timing
The design and manufacture of ultrasonic cutting knives may have challenging narrow blade design requirements. At the same time, vibrating tools with small amplitude may sometimes lead to premature failure when they are not under load. Therefore, the ultrasonic signal sent from the ultrasonic generator should be mechanically timed correctly to make the tool vibrate fully in front of the cutting edge to meet the requirements of food products. Vibration must be avoided before contact. Food deformation caused by contact with non vibrating cutting surface must be avoided.
2. Vibration amplitude
The term "amplitude" describes the cutting surface of the micro distance angle of vibration. The amplitude can be mechanically adjusted by the controller, the booster, and the digital generator. The degree of amplitude has an impact on the cutting process and must be adjusted to suit each demand application.
1> Soft foods and those with multiple textures usually require higher content amplitudes. Examples are: soft candy and nougat, soft cheese and sandwiches and packages containing nuts or fruits, products containing various soft and hard materials, cakes and bread.
2> Strong foods usually have low amplitude requirements. Examples are: frozen food, hard cheese, vegetables.
3. Reduce speed
The speed at which the cutting tool enters and passes through the material is also a process variable, and the application should be optimized for each process. Sometimes it is necessary to use the shell to penetrate the product. Slowly avoid deformation, and then increase the speed in the knife to achieve the best cutting effect.
4. Final vibration timing
According to the consistency of the material to be cut, the finished slice may tend to stick to the side of the ultrasonic cutting knife after ultrasonic vibration. Therefore, the tool taken out of the product while maintaining ultrasonic vibration can use properties to release cleaner and consistent slices without friction.
