The use of ultrasonics is becoming increasingly important for the food industry.
Ultrasound in Food Processing enables scientists, engineers andmanagers in food manufacturing to make informed choices about anew and important area of research and development. It will also be avaluable reference to people working in other areas of ultrasound research and instrument manufacture. Wide ultrasonic food cutting machine Vibrating Guillotine Knives.
The ultrasonic cutter is composed of a "transducer" that generates vibration and an "oscillator" that drives the transducer. A piezoelectric element is used for the transducer. When voltage is applied, the piezoelectric element displaces the transducer by a few micrometers. Periodically applying voltage generates vibration. Each object has its special frequency, by which the object is stable and easy to vibrate. By adding an external force that corresponds to that special frequency, a small force can obtain a large vibration. This phenomenon is called resonance. In the ultrasonic cutter, the piezoelectric element generates a force that resonates the whole body, from the transducer to the blade tip, generating a large vibration at the tip. The oscillator periodically generates voltage to resonate and drive the transducer. Using a component of the ultrasonic cutter called the horn to ring the cross--sectional area, from the piezoelectric element to the blade tip, can obtain a larger vibration
What's the principle of ultrasonic cutting?
RPS-SONIC offers high quality ultrasonic food cutting components, including ultrasonic generators, transducers, guillotines and slitters.
Ultrasonic food processing involves a vibrating knife (guillotine) producing a nearly frictionless surface that minimizes buildup on the blade surface. The ultrasonic blades cleanly cuts --sticky products and inclusions such as nuts, raisins & morsels without displacement. Ultrasonic cutting is used by many of the world's largest and most prestigious food producers.
-RPS-SONIC has worked in ultrasonic area more than 10years. RPS-SONIC'S ultrasonic components are a widely used and proven technology. The "guillotine" blades are crafted in titanium and employ the latest FEA design technology for trouble free operation and reliability.
Ultrasonic cutting, guillotining or sititing, can be thought of as an enhancedconventional cutting process. The blade has a cutting edge and a shank. Theultrasonic vibration of 20kHz moves the cutting tip rapidly forward andback, superimposed on a forward movement of perhaps 5 m/min. Thisoscillating movement applies an intermittent cutting force to the crack tipand so controls this crack (cut) propagation or growth minimizing the stresson the bulk material. The repeated application of the cutting tip to theproduct applies a local fatiguing effect which reduces significantly theoverall required force to break the bonds of the bulk material. A usefulanalogy is the hammer drill or the pneumatic road drill concepts. A secondaspect to ultrasonic cutting is the friction reduction of the blade shank as itfollows the tip into the opening cut. In conventional cutting the blade has tocompress the bulk material to allow a gap the width of the blade to passthrough; the compression to the bulk applies a tensile rupturing force at thecrack tip. With ultrasonic cutting the whole blade moves or vibratescontinuously as it stretches and contracts. This very high-frequency movement effectively reduces the co-efficiency of friction to a verylow level, enabling the blade to slide through the bulk material withconsiderable reduction to the compression and contact, giving a forcereduction and decreased smearing effects.
