Speed in water = 1500m/s
Ultrasound applications are numerous : sonar, medical imaging, cleaning, depolymerization, … |
 |
liquid medium is necessary to allow ultrasound propagation |
|
generation of mechanical vibrations |

|
Cavitation bubbles (5000 K and 1000 atm) |
Principle
| Bubble cavitation in contact with plant cells allows destructuring plant cells and, in combination with microwave obtaining high extraction yield. | |
  Example : basil extraction |
|
Technology
An ultrasonic set consists of a generator, which sends a signal with a determined frequency (20kHz) to a sonotrode transforming the electrical signal into vibrations that are transmitted in the liquid medium.
IDCO/REUS Technology
 |
The Extractor technology solution is to send electrical signal to piezometers located outside of the tank. The sonotrodes are welded to the tank, wich ensures unequaled durability (unlike a solution by gluing) |
