Ultrasonic Food Cutter Product Description
Principle of ultrasonic cutting machine:
Ultrasonic cutting machine uses ultrasonic energy to heat and melt the material to be cut to achieve the purpose of cutting the material. The principle of the ultrasonic cutting machine is completely different from the traditional cutting.
Traditional cutting machine:
Use a knife with a sharp edge to press against the material to be cut. This pressure is concentrated at the cutting edge, and the pressure is very large, exceeding the shear strength of the material to be cut, and the molecular bonds of the material are pulled apart and cut.
Since the material is pulled apart by strong pressure and rigidity, the cutting tool's edge should be very sharp, and the material itself has to bear relatively large pressure. The cutting effect is not good for soft and elastic materials, and it is more difficult for sticky materials.
Ultrasonic food cutting machine:
Ultrasonic cutting machine is a kind of equipment that uses wave energy for cutting processing. Ultrasonic cutting does not require sharp edges, nor does it require a lot of pressure, and will not cause chipping or damage to the material being cut.
Because the cutting knife is doing ultrasonic vibration, the friction resistance is very small, and the material to be cut is not easy to stick to the blade. This is particularly effective for cutting viscous and elastic materials, frozen materials such as food, rubber, etc., or objects that are inconvenient to apply pressure.
Ultrasonic food cutting machine composition:
The ultrasonic cutting machine is composed of an ultrasonic transducer, an ultrasonic horn, an ultrasonic cutting knife, and an ultrasonic generator.
Ultrasonic generator: Mains electricity is converted into high frequency and high voltage alternating current, which is output to the ultrasonic transducer. Ultrasonic transducer is equivalent to energy conversion device, it can convert the input electric energy into mechanical energy, namely ultrasonic. The ultrasonic transducer stretches back and forth in the longitudinal direction, and the frequency of the stretch movement is equal to the frequency of the high-frequency alternating current supplied by the driving power source.
Ultrasonic horn: The ultrasonic horn amplifies the output amplitude of the ultrasonic transducer.
Ultrasonic cutter: further amplify the amplitude and focus the ultrasound.
Ultrasonic wave is output, and the cutting knife is used to concentrate the ultrasonic energy into the cutting part of the material to be cut. Under the action of huge ultrasonic energy, this part instantly softens and melts, and its strength drops greatly. Only a small amount of force is required to achieve the purpose of cutting materials.
According to the ultrasonic cutting machine, the cutting method can be divided into: knife cutting machine and anvil cutting machine. The two cutting methods are suitable for different process conditions and cutting objects.
Ultrasonic cutter type cutting machine:
The ultrasonic energy is directly loaded on the cutter, and the cutter becomes a cutter with ultrasonic waves. When cutting the material, the material is mainly softened and melted by ultrasonic energy, and the cutting edge of the cutter only plays the role of cutting seam positioning, ultrasonic energy output, and separating the material. This cutting method is suitable for cutting thick, thick, and long materials that are inconvenient to set up cutting boards. Such as the raw rubber output from the rubber mixing machine, cutting pipes, cutting frozen meat, candy, chocolate, printed circuit boards, or hand-held cutting machines, etc.
Ultrasonic chopping board cutting machine:
The basic structure is similar to the ultrasonic cutter type cutting machine, the ultrasonic output part is not a cutting knife, but a standard ultrasonic plane mold. The mold is equivalent to an anvil that is vibrating ultrasonically. The cutting knife can still use the traditional, any shape, but the sharpness of the cutting edge is reduced, and the life of the cutting knife is greatly extended.
