Description

Technical Field

[0002] Ultrasonic extraction equipment is mainly used in traditional Chinese medicine, food, agricultural products, health products and other industries. It is widely used in the extraction of effective ingredients from traditional Chinese medicine and natural plants, and is suitable for various solvents (water or ethanol, petroleum ether, acetone and other organic solvents). The ultrasonic extraction equipment for Chinese herbal medicine utilizes the cavitation effect, mechanical effect and thermal effect produced by ultrasound in liquid to enhance the dissolution and diffusion of effective ingredients in Chinese herbal medicine and achieve efficient extraction. The vibration energy of ultrasound can destroy the cell wall of Chinese herbal medicine, making the effective ingredients in the cell easier to dissolve, and accelerate the penetration and dissolution of solvent molecules into Chinese herbal medicine ingredients. Therefore, without changing the characteristics of traditional Chinese medicine and natural plant extraction, on the basis of continuous countercurrent extraction equipment, combined with the principle of ultrasonic extraction (using the cavitation effect of ultrasound to accelerate the leaching of effective ingredients), the production cost is greatly reduced.
