Shanghai Birang Laboratory Ultrasonic Extractor.
Laboratory ultrasonic extractor, laboratory ultrasonic extractor supply information, Shanghai Billion Instrument Co., Ltd. to provide you with
The principle of ultrasonic extraction of traditional Chinese medicine and natural medicine: ultrasonic generator, the vibrator emits ultrasonic waves into the extraction solvent, and the 'cavitation effect' generated by the ultrasonic wave in the extraction solvent, the thermal effect and the mechanical action can effectively break the cell wall of the medicine, and make it effective The component is in a free state and dissolved in the extraction solvent. On the other hand, the molecular motion of the extraction solvent is accelerated, so that the active components in the extraction solvent and the medicinal material are in rapid contact, and are mutually dissolved and mixed.
Ultrasonic extraction (also known as extraction) is a new advantage of low extraction temperature, high extraction rate and short extraction time. It is used by innovative people to extract Chinese herbal medicines and various effective extracts of animals and plants. It is an alternative to traditional shearing technology. The method realizes modern high-tech means of efficient, energy-saving and environmentally-friendly extraction.
Ultrasonic extraction advantages
1. High extraction efficiency: The unique physical properties of ultrasonic waves cause the cell tissue to break or deform, which makes the extraction of active ingredients of traditional Chinese medicine more complete, and the extraction rate is significantly improved by 50-500% compared with the traditional process;
2. Short extraction time: Ultrasound-enhanced Chinese medicine extraction usually obtains the best extraction rate in 24-40 minutes, and the extraction time is greatly shortened by more than 2/3 compared with the traditional method, and the raw material processing capacity of the medicinal materials is large;
3. Low extraction temperature: The optimal temperature for ultrasonic extraction of Chinese medicinal materials is 40-60 ° C, which has a protective effect on the active ingredients in the heat-labile, easily hydrolyzed or oxidized medicinal materials, and greatly saves energy consumption;
4. Wide adaptability: Ultrasonic extraction of Chinese herbal medicines is not limited by the polarity of components and molecular weight, and is suitable for the extraction of most kinds of Chinese herbal medicines and various components;
5. The extraction of chemical liquid has less impurities, and the active ingredient is easy to be separated and purified;
6. The extraction process has low operating cost and significant comprehensive economic benefits;
7. The operation is simple and easy, and the equipment maintenance and maintenance are convenient.
Increase extraction rate by 50% - 500%
The extraction time (minutes) is shortened by 2/3 or more
The extraction temperature is 40-60 ° C to protect the active ingredients.
