Microgrid Ultrasonic Atomizer

What is an ultrasonic atomizer used for?

In traditional ultrasonic atomizers, the entire bulk liquid is atomized to produce mist droplets. In applications such as atomization of chemicals, a special type of ultrasonic transducer was used , .

Which ultrasonic transducers are used for atomization purposes?

Ultrasonic transducers used for atomization purposes in biomedical, pharmaceutical, or industrial applications, such as surface acoustic wave (SAW) transducers, array of micromachined nozzles, and Fourier horn micromachined nozzles with or without a central channel, are all presented and compared.

How does ultrasonic atomization work?

There are no moving parts and only mechanical vibrations generated by the supplied electrical energy are used for the generation of the droplets. Ultrasonic atomization is the ejection of fine droplets from a liquid film formed on an ultrasonically vibrating surface.

Is ultrasonic atomization a greener technology?

These qualities confirm the greener processing capabilities of this technology. The application of ultrasonic atomization for the separation of chemicals is a relatively new technology. In the past two decades, several studies have been conducted in this area.

What are the advantages of ultrasonic atomizer design?

The advantages of the early design of the ultrasonic atomizer design and the general commercial atomization are mainly that the atomization particle size generated is quite uniform and mostly 7 μm (80%), while the traditional commercial atomizers are 20 μm to 150 μm, the distribution is quite uneven. And the energy required is high, about 23.5 W.

What is ultrasonic atomization & microencapsulation?

Microencapsulation is another application area that ultrasonic atomization that has been employed in the pharmaceutical industry, which can be described as a process by which an active compound is entrapped within a spherical particle, coated with a thin film.
