1800W Customized Submersible Ultrasonic Cleaner In Producing Wine
And Olive Oil
Introduction
Ultrasonic energy has been used for a wide variety of applications
in industry, medicine and science. In the analytical chemistry
Reld, most applications lie in the ability of ultrasound to extract
compounds from the solid matrix. Solid}liquid extraction with the
use of ultrasonic energy (i.e. ultrasound-assisted extraction) has
been successfully applied for many years as a sample pretreatment
method to extract organic compounds from matrices to which they are
weakly bound (e.g. environmental samples). Sonication methods have
been compared to other methods for pretreatment of solid samples
(e.g. Soxhlet extraction, accelerated solvent extraction and
supercritical Suid extraction), being competitive to them owing to
its simplicity, efRciency and ease of use. Moreover, sonication
methods do not involve the use of high temperatures, pressures or
concentrated and harmful chemicals.
Usually, ultrasound has been applied to the sample with the use of
ultrasonic cleaning
baths. Ultrasonic cleaning baths are readily available, large
numbers of samples can be simultaneously
treated and low-cost instrumentation is involved, but they lack the
capability of transmitting sufRcient ultrasonic power to produce
the desired effects on the sample.
How do I get the best ultrasonic cleaning?
There are many considerations important to ultrasonic cleaning.
Optimising these variables will produce the best cleaning. The most
important decisions to be made are choosing the proper cleaning
solution, cleaning at the right temperature for the correct amount
of time, and choosing the right size and type of ultrasonic
cleaner.
Immersible Transducers (Submersible)
Ultrasonic transducer elements sealed in a liquid-tight housing are
an option to transducer elements permanently bonded to the side or
bottom of a cleaning tank.
The major benefits of immersible ultrasonic transducers are that
they are easy to service and can be added to existing equipment,
often without extensive tank modifications.
This includes standard individual frequencies from 25 kHz to 270
kHz as well as multiple frequencies in a single or multiple units.
Ultrasonics immersible tranducers are intended to withstand the abuse unavoidable in a heavy
industrial environment. Standard units are constructed of heavy
gauge 316L stainless steel with other materials available for use
in challenging process applications.
Units are pre-tested prior to sealing to assure that all transducer
elements are performing exactly to specification. Once sealed by
full penetration welding, the finished units are function tested in
liquid for a minimum of 24 hours prior to shipping.
immersible ultrasonic transducers are powered by AG Sonic proprietary ultrasonic generators. In
installations of large numbers of transducers, Ultrasonics
generators can each provide up to 2,000 watts of ultrasonic power
each reducing the number of generators required by as much as half.
Multiple generators can be integrated in a common electrical
enclosure. Cooling and environmental protection can be included if
required.
Immersible ultrasonic transducers do not require attachment to the tank (other than to hold them in
position) to function efficiently. As a result, transducers can be
moved from tank to tank and positioned as required for special
applications when needed.
Ultrasonics experienced engineering team is available to design a
custom immersible ultrasonic transducer installation for any
cleaning or process application.

What is Ultrasonic Cleaning
In a process termed "cavitation", micron-size bubbles form and grow
due to alternating positive and negative pressure waves in a
solution. The bubbles subjected to these alternating pressure waves
continue to grow until they reach resonant size. Just prior to the
bubble implosion, there is a tremendous amount of energy stored
inside the bubble itself. Temperature inside a cavitating bubble
can be extremely high, with pressures up to 500 atm. The implosion
event, when it occurs near a hard surface, changes the bubble into
a suction jet about one-tenth the bubble size, which travels at
speeds up to 400 km/hr away from the hard surface. With the
combination of pressure, temperature, and velocity, the jet frees
contaminants from their bonds with the substrate. Because of the
inherently small size of the jet and the relatively large energy,
ultrasonic cleaning has the ability to reach into small crevices
and remove entrapped soils very effectively.
Applications of Ultrasound-Assisted
Extraction for Element Speciation
Ultrasound extraction shows advantageous features for element
speciation. Organometallic species can be extracted without changes
in their integrity under suitable extraction conditions. Both
organic and
aqueous extraction media have been used for separation of
organometallic and inorganic species from
the solid matrix, most applications using ultrasonic
cleaning baths for extraction.
