Ultrasonic can extract natural medicine and traditional Chinese medicine. Its mechanism is to add extraction solvent into the container, crush or cut the Chinese herbal medicine into granules according to needs, and then put them into the extraction solvent. The outer wall of the container is bonded with transducer vibrator or sealed in stainless steel box and put into the container. Start the ultrasonic mixer, the vibrator sends ultrasonic wave to the extraction solvent, and the ultrasonic wave is extracted The cavitation effect and mechanical action produced in the solvent, on the one hand, can effectively break the cell wall of medicinal materials, so that the effective components are in free state and dissolved in the extraction solvent, on the other hand, it can accelerate the molecular movement of the extraction solvent, so that the extracted solvent and the effective components in the medicinal materials can quickly contact, dissolve and mix with each other.
The type, size and rotating speed of ultrasonic mixer have influence on the distribution of mixing power between the overall flow and turbulent fluctuation. Generally speaking, the power distribution is beneficial to the turbulent pulsation, while the propeller agitator is beneficial to the overall flow. For the same type of agitator, under the same power consumption, the power of large diameter and low speed agitator is mainly consumed by the overall flow, which is conducive to macro mixing. The power of small diameter and high speed agitator is mainly consumed by turbulence pulsation, which is beneficial to micro mixing.
