Description

A botanical active ingredient synergistically effected by drum-type countercurrent centrifugal stirring and ultrasonic waves extraction device

technical field

The utility model belongs to the technical field of component separation and extraction, and in particular relates to a device for extracting effective plant components through the synergistic effect of drum type countercurrent centrifugal stirring and ultrasonic waves.

Background technique

Natural plants contain many beneficial functional ingredients. If they can be extracted efficiently and completely, they will be widely used in many fields, such as daily chemical, pharmaceutical, food, health care products and biochemical industries. At present, the main methods for extracting active ingredients from plants include dipping, decocting and reflux extraction. These methods all use appropriate solvents to treat plants at normal temperature or under heating conditions to dissolve useful components therein. The advantages are simple process, convenient operation, and are almost applicable to the extraction of all plant components. However, due to static extraction, it is difficult to The extraction rate is poor and takes a long time. In response to the above problems, in recent years, people have gradually introduced dynamic stirring into the traditional static extraction method to increase the extraction rate and yield, but most of the methods currently used are simple mechanical stirring of the extraction solution to increase the dissolution and diffusion rate. , Since the simple mechanical stirring process does not generate centrifugal force, it cannot fully dissolve and separate the ingredients in the plant more effectively.
