Suggested Working Principles, Methods, And Mechanisms Of Ultrasonic Processing Equipment

Working principle of ultrasonic processing instrument
Ultrasonic extraction, with its advantages of low extraction temperature, high extraction rate, and short extraction time, is applied to the extraction of effective content in traditional Chinese medicinal materials, oils, and various animals and plants. It is a modern high-tech method that replaces traditional cutting techniques and achieves energy-saving, environmentally friendly extraction. The superiority of ultrasonic extraction of traditional Chinese medicine is based on the special physical properties of ultrasound, mainly through the rapid mechanical vibration waves generated by voltage transducers to reduce the force between the target extract and the sample matrix, thus achieving solid-liquid extraction separation.
The simple method and mechanism for ultrasonic extraction of traditional Chinese medicine and natural drugs are as follows: adding extraction solvents (such as water, ethanol, or other organic solvents) to the container, crushing or cutting the traditional Chinese medicine into granules as needed, and placing them in the extraction solvent; Attach the transducer vibrator to the outer wall of the container or seal the vibrator in a stainless steel box and insert it into the container; Turn on the ultrasonic generator, and the oscillator emits ultrasonic waves into the extraction solvent. The "cavitation effect" and mechanical action generated by ultrasonic waves in the extraction solvent can effectively break the cell wall of the medicinal material, making the active ingredients in a free state and dissolve in the extraction solvent. On the other hand, it can accelerate the molecular motion of the extraction solvent, allowing the extraction solvent and the active ingredients in the medicinal material to quickly come into contact, dissolve and mix with each other.
The main functions of the ultrasonic processing instrument are:
1. Automatic resonance point and power control, eliminating the need for frequent manual energy adjustment
2.99 hour process control timer, controlling the total working time from 1 second to 99 hours, suspending the current running task in real time
3. The working hours are displayed in a cumulative state
4. On/Off Pulse Timer
Ensure high intensity processing of temperature sensitive samples, with both on and off cycles selectable from 1 second to 99 minutes
5. Automatic amplitude compensation ensures that the probe amplitude does not change due to load changes during the ultrasonic process
6. Easy to operate, menu operation, direct typing, the instrument adopts a large screen display, and all functions are displayed on the LCD screen.
The main applications of ultrasonic processing equipment are:
1. Extraction of traditional Chinese medicine, fragmentation of cells, bacteria, and viral tissues. For example, the extraction of cell contents.
2. The dispersion and homogenization of material particles, as well as the emulsification of products. For example, the dispersion of nanomaterials.
3. Accelerate dissolution, accelerate chemical reactions. For example, used in chemical synthesis.
