Ultrasonics is the science of sound waves above the limits of human audibility. The frequency of a sound wave determines its tone or pitch. Low frequencies produce low or bass tones. High frequencies produce high or treble tones. Ultrasound is a sound with a pitch so high that the human ear cannot hear it. Frequencies above 18 Kilohertz are usually considered to be ultrasonic.

OERATING PRINCIPLE---- High frequency vibrations are produced by the velocity horn- generally made out of S.S.316, which is immersed in the liquid to be processed. These vibrations produced millions of microscopic vacuum bubbles. Which form and implode at a high rate. The normal frequency is twenty-two thousand cycles per second. This phenomenon is known as a CAVITATION. Cavitation gives rise to intense local pressure waves & micro streaming of the liquid around the point of collapses. This in turn leads to high shear gradients that are responsible for the chemical process such as homogenization. Ultrasonic Processor finds its application in ----------- 1) Pharmaceutical Industries 2) Chemical Industries. 2) Biotechnology units 4) Research Institutes/ colleges/Laboratories.
APPLICATION----- Tissue processing (Plants & Animal Tissues) De-gassing & De- aerating of liquids. Formulations. Emulsification of Immiscible liquids. Homogenization. Particle dispersion. Cell disintegration. Ultrasonic processor consists of two parts--- 1) Ultrasonic Generator 2) Ultrasonic Horn. Ultrasonic generator will produce high frequency ultrasonic power & same power is connected to Ultrasonic horn. These transducers used PZT crystals in sandwich form to convert the electrical power in to vibrations leading to cavitation. This horn is used for the produce the Cavitation in the liquid. |

Ultrasonic Cleaning is faster, more through & safest method outperforming sound waves moves through a solution creating a effect called Cavitation, the rapid formation of implosive microscopic bubbloes.
Heat enhances this process, the deep penetrative cleaning action of ultrasonic removes even the most stubborn dust & contaminations. Applications :-
Ultrasonic can be used to remove contaminations like oil, scale, buffing compound, grinding abrasive, rust, oxide, resin, dust, inks, etc.

For cleaning of spinneretts or pack assemblies/candle, a two-stage cleaning system is necessary. The first stage, known as precleaning, entails the removal of polymeric material or the reduction of this material to an ash. In many instances, this precleaning stage completely removes the polymeric materials. However, materials such as carbon residue or titanium dioxide are inert to the pyrolysis or volatilization process and must be removed by other methods. In the past, fine drills, broaches, or wires were used to remove this inert matter, but because of the damage caused to the spinneretts by using these methods, an alternative method had to be found. The use of ultrasonic systems is now the standard in the Fiber Industry.The ultrasonic cleaner is a device in which thorough and powerful mechanical agitation is provided to a liquid bath. The ultrasonic cleaner, as its name implies, incorporates sound to accomplish its purpose. Sound waves, which are pressure waves, move through the bath and induce cavitation. It is the cavitation which produces a scrubbing action at the surface of the object being cleaned and releases energy to loosen and lift dirt from hard to reach surfaces.ORION Ultrasonics is supplying the custom built equipments for spinneretts, sieves & candle cleaning as per customers requirement.
