Ultrasonic Essential Oil Extraction

The ultrasonic essential oil extraction is composed of ultrasonic drive power supply+ultrasonic transducer+tool head+horn+flange combined with the matching mixer of the reaction tank. Ultrasonic plant essential oil extraction equipment is to extract plant essential oil using the cavitation principle of ultrasonic. Ultrasonic cavitation effect refers to that under the action of strong ultrasound, a large number of bubbles will be generated in the liquid, and small bubbles will gradually grow and increase with the ultrasonic vibration, and then suddenly break and split, and the split bubbles will continue to grow and break. When these small bubbles collapse rapidly, high temperature and high pressure are generated in the bubble, and strong local shock waves are generated in the liquid near the bubble because the liquid around the bubble rushes into the bubble at high speed, which also forms local high temperature and high pressure, resulting in ultrasonic crushing, emulsification and extraction. The extraction methods of essential oil mainly include distillation, squeezing, ancient liposuction, organic solvent extraction (IS), supercritical carbon dioxide extraction, ultrasonic extraction, and microwave-assisted steam distillation.
