AI Technical Summary
In existing extraction devices, compressed air is introduced through an air stone to cause the extract to tumble, resulting in uneven contact between the extract and the medicinal materials inside the filter cartridge. In particular, the mixing degree is uneven between the edge and the center of the filter cartridge, which affects the extraction efficiency.
The system employs a motor-driven stirring and extrusion assembly combined with an ultrasonic generator. The stirring blades and extrusion rollers uniformly stir and extract the raw materials in the filter box, ensuring that the medicinal materials and the extract are in uniform contact.
This achieves uniform contact between the medicinal materials and the extract in the filter chamber, improving the extraction effect and efficiency, and ensuring the uniformity of mixing in all areas of the filter cartridge.

Description
Technical Field
[0001] This utility model relates to the field of extraction technology, and in particular to an ultrasonic multi-stage continuous extraction device for plant extraction. Background Technology
[0002] The chemical composition of traditional Chinese medicine is very complex, containing a variety of effective components, ineffective components, and toxic components. Extracting its effective components and further separating and purifying them to obtain effective monomers is an important part of the research of traditional Chinese medicine. Currently, extraction devices are commonly used for the extraction of traditional Chinese medicine.
[0003] Existing extraction devices primarily utilize the principle of pressure distillation, crushing and squeezing traditional Chinese medicine materials before distillation to extract a pure medicinal liquid. However, the patent application (CN221950620U) proposes a different approach. It uses a crushing mechanism to break down the medicinal materials, facilitating the extraction of components. The processed materials and extract are fed into a filter cartridge through a feed pipe. Then, the first and second solenoid valves are closed, and the heating plate and ultrasonic generator are activated. Ultrasonic waves are transmitted to the mixture of extract and materials, increasing the frequency and speed of movement and enhancing the penetrating power of the extract. This accelerates the entry of the medicinal components into the extract. Compressed air is introduced into the filter cartridge through an air inlet pipe, where it is converted into bubbles by an air stone. These bubbles tumble the extract, causing the materials to tumble along with it, thus improving the overall extraction effect. Pressure and temperature sensors monitor the air pressure and temperature to maintain a suitable environment during the extraction process, further enhancing the extraction efficiency and effectiveness.
[0004] However, in current devices, compressed air is introduced through the air stone to tumble the extract, which can easily lead to uneven contact between the extract and the medicinal materials throughout the filter cartridge, resulting in uneven mixing between the edges and the center of the filter cartridge.
[0005] Therefore, it is necessary to provide an ultrasonic multi-stage continuous extraction device for plant extraction to solve the above-mentioned technical problems. Utility Model Content
