Description

technical field

[0001] The invention relates to the technical field of ultrasonic extraction equipment for effective components of medicines, foods, and natural products, in particular to a multiple-frequency ultrasonic cavitation two-water phase closed-loop continuous extraction device. Background technique

[0002] At present, most of the traditional Chinese medicine production plants are limited by the pharmacopoeia regulations, and all use single-tank, batch-type extraction equipment. The disadvantages are low overall efficiency, high production costs, and high investment in large-scale production. In recent years, some dynamic countercurrent continuous extraction equipment have appeared, such as horizontal rotary continuous extraction device, tank group type countercurrent extraction device, tubular spiral continuous countercurrent ultrasonic extraction device, tank group multi-dynamic ultrasonic countercurrent continuous extraction device, etc. Although they got rid of...
