Problems solved by technology

[0007] The biggest disadvantage of traditional percolation is that medicinal materials can only be crushed into coarse powder, and the stacking height should not exceed 6 to 7 times the diameter of the percolation barrel. When the solvent flows from the top of the medicinal powder to the bottom of the medicinal powder, it is already in a dynamic equilibrium of content, and the difference in concentration gradient cannot fully reflect , the percolation effect is poor; the medicinal materials are too thin, and the stacking height is too high, which will cause the solvent to flow slowly or not, and percolation cannot be realized, the production efficiency is low, and the operation is unstable

Description

technical field [0001] The invention relates to a percolation device, more specifically to a multi-layer structure percolation device. Background technique [0002] The extraction process of active ingredients of traditional Chinese medicine is a key process that affects the leaching of active ingredients of drugs. At present, most of the extraction methods used in China are: percolation method, dynamic circulation extraction method, supercritical fluid extraction method, ultrasonic extraction technology, intelligent continuous countercurrent extraction method, continuous extraction method, etc. Countercurrent ultrasonic enhanced extraction method, Soxhlet extraction method, etc., each have their own characteristics, and can extract active ingredients for a certain type of characteristics or all Chinese medicinal materials. [0003] The percolation method is one of the effective methods for extracting ingredients, which is mainly aimed at the extraction and separation of act...
