Ultrasonic extractorIt is mainly based on the principle of ultrasonic action. The rapid mechanical vibration wave generated by the piezoelectric transducer acts on the cell wall (cell membrane) of the material being fed. The powerful mechanical wave can destroy the cell wall of plant cells (cell membrane of animal cells), so that the internal solutes in cells can be quickly dissolved into the extraction solvent, and then the extract is obtained through filtration, centrifugation, ethanol precipitation, concentration, spray drying and other processes.
What are the main advantages of ultrasonic extractors?
1. High extraction efficiency: The physical properties of ultrasound can promote the breaking or deformation of plant cell tissues, making the extraction of effective ingredients in traditional Chinese medicine more complete, and the extraction rate is significantly increased by 50-500% compared to traditional processes;
2. Low extraction temperature: The ultrasonic extraction of traditional Chinese medicine takes place at a temperature of 40 to 60 ℃, which provides protection for the active ingredients in herbs that are unstable, easily hydrolyzed, or oxidized when exposed to heat, while greatly reducing energy consumption; Configurable cooling device.
3. The extracted medicinal solution has fewer impurities and the effective ingredients are easy to separate and purify;
4. Easy to operate, convenient equipment maintenance and upkeep;
5. Wide adaptability: Ultrasonic extraction of Chinese medicinal materials is not limited by component polarity or molecular weight, and is suitable for the extraction of the vast majority of types of Chinese medicinal materials and various components;
6. The extraction process has low operating costs and significant comprehensive economic benefits;
7. Short extraction time: Ultrasonic enhanced traditional Chinese medicine extraction usually takes 24-40 minutes to obtain * extraction rate, which greatly shortens the extraction time by more than 2/3 compared to traditional methods, and requires a large amount of raw material processing for medicinal materials.
