20kHz Ultrasonic Extraction of Botanicals Ultrasonic Extraction Machine

20Khz Ultrasonic Extraction of Botanicals ultrasonic extraction machine

The ultrasonic extraction tank can extract the effective ingredients in health care medicines. The previous method was soaking, but now the use of ultrasonic waves can greatly speed up the extraction process, from the original half a month or even longer to 30-40 minutes, and the yield of active ingredients is high, the purity is high, and there are few impurities. Liquor aging technology Alcoholization process aging equipment, accelerates association, reduces harmful indicators, reduces solids, accelerates aging and improves taste. The main reasons affecting the quality and taste of liquor are too many harmful impurities, insufficient association of water molecules and liquor molecules (requiring a long time and slow reaction). Ultrasound can greatly shorten the association time to 30 minutes, greatly reduce harmful indicators, and greatly reduce emetic solids. Thereby greatly improving the quality and mouthfeel of liquor in a short period of time. It is an advanced new method and technology for liquor processing. It can also be used for the treatment of other wines, such as rice wine, beer, red wine, etc. Especially health wine, because the ultrasonic wave can not only age the wine, but also extract the active ingredients in the health medicine.

Ultrasonic extraction of traditional Chinese medicine: in the extraction of traditional Chinese medicine, ultrasonic circulation extraction technology has been widely used. Ultrasonic extraction is to use the cavitation effect of ultrasonic waves to increase the penetration of solvents, increase the dissolution rate and the number of dissolution of drugs, thereby increasing the diffusion of material components, shortening the extraction time, and accelerating the extraction process. 1. The extraction temperature is low, and low temperature extraction can be used, which will not damage the medicinal properties of heat-sensitive drugs. 2. The extraction time is short, the extraction rate is high, the resources of medicinal materials are saved, the output is increased, and the production cost is reduced. 3. Adapt to a variety of solvents to meet the needs of various extractions.

The superiority of ultrasonic extraction of Chinese medicinal materials is based on the special physical properties of ultrasonic waves. Mainly, the rapid mechanical vibration waves generated by the piezoelectric transducer are used to reduce the force between the target extract and the sample matrix to achieve solid-liquid extraction separation.
(1) Accelerate the movement of medium particles. When ultrasonic waves with a frequency higher than 20 KHz propagate in a continuous medium (such as water), according to the principle of Huygens waves, the movement of medium particles (including the particles of important active ingredients of medicinal materials) will be caused on the wave front of its propagation. Make the medium particles move to obtain huge acceleration and kinetic energy. The acceleration of the mass point can generally reach more than 2,000 times the acceleration of gravity after calculation. Because the medium particle acts on the particle of the effective ingredient in the medicinal material by ultrasonic energy, it obtains huge acceleration and kinetic energy, and quickly escapes from the medicinal material matrix and dissociates in the water.
(2) Cavitation. The propagation of ultrasonic waves in liquid media produces a special "cavitation effect". The "cavitation effect" continuously produces countless micro-cavitations with internal pressures reaching thousands of atmospheric pressures and continuously "explodes" to produce microscopically powerful shock waves that act on Chinese herbal medicines. , so that the ingredients of the medicinal materials are "bombarded" to escape, and the matrix of the medicinal materials is continuously eroded, and the medicinal ingredients that do not belong to the plant structure are continuously separated. Accelerate the leaching and extraction of active ingredients of plants.
(3) Ultrasonic vibration homogenization (Sonication) makes the effect on each point in the sample medium consistent, making the extraction of the entire sample more uniform. To sum up, under the action of the ultrasonic field, the medicinal substances in Chinese medicinal materials not only obtain their own huge acceleration and kinetic energy as medium particles, but also obtain a strong external impact through the "cavitation effect", so they can be separated efficiently and fully. .
