Problems solved by technology

[0011] The continuous extraction of traditional Chinese medicines reported in the above-mentioned open literature has adopted some new methods and equipment, some of which use external circulation channels, some of which use the integration of stirring, mixing, conveying, and pressure filtration, or adopt continuous countercurrent percolation tank groups, so that the extraction efficiency It has been improved, but there are also some shortcomings, such as high energy consumption, some need freezing methods, and equipment investment increases

example 1

[0025] Example 1: Extraction and concentration of dragon's blood: extract 5-6 times according to the normal process, consume about 15 times the alcohol, and take about 10 hours, but using this method can greatly improve the efficiency: add it to the retort 1 at one time Alcohol is about 8 times, add the coarse powder of dracaena medicinal material in the extracting tank 4, the alcohol in the distillation tank 1 volatilizes upwards after being heated, meets the heat exchanger 2 to cool slightly and then drops into the extracting tank 4, wait until the liquid level When it is higher than the highest point of the siphon tube, all the siphons will automatically enter the distillation tank 1. Repeat this several times, and the extraction will be complete in about 4 hours. Close the upper interface of the extraction tank 4, connect the condensed water of the condenser 3, and connect it to the storage tank 12. The extract is concentrated in the distillation tank 1, and the alcohol ent...

example 2

[0026] Example 2: Extraction and concentration of Radix Astragali: Extract 2-3 times according to the normal process, use about 20 times of water, and take about 8 hours, but using this method can greatly improve the efficiency: add about 10 times of water to the distillation tank at one time , add astragalus crude powder in the extraction tank 4, the water in the distillation tank 1 is heated and volatilizes upwards, and when it is slightly cooled by the heat exchanger 2, it becomes liquid droplets and then drops into the extraction tank 4. When the liquid level is higher than the highest point of the siphon , automatically all siphon into the retort 1, repeat this several times, and the extraction is complete in about 3 hours, close the upper interface of the extraction tank 4, connect the condensed water of the condenser 3, and connect it to the storage tank 12, and the extract is in the retort 4 Concentrated in medium, the water enters the storage tank 12 after heating and ...

Abstract

The invention relates to a traditional medicine continuous circulate extracting concentrating method and relative device, wherein said device comprises drug extracting pot, solvent pot, and distill pot. The inventive method comprises that: adding extracting solvent into distill pot, heating, condensing via tube, flowing into extracting pot, immerging drug, reaching some level, adsorbing extractedliquid into distill pot, circulating until complete extraction; heating extracted liquid in distill pot, condensing solvent, guiding into one storage pot, entering into next process, and the solvent in storage pot can be extracted again. The invention concentrates after extraction, with high efficiency, reduced energy consumption and saved time, while the solvent can be saved more than 50%.

Description

technical field [0001] The invention relates to a method and equipment for extracting traditional Chinese medicine, in particular to a method and equipment for continuously extracting traditional Chinese medicine. Background technique [0002] The existing traditional Chinese medicine preparation technology usually adopts the intermittent extraction method, that is, put the traditional Chinese medicine in the extraction tank, add water and heat it for a certain period of time, then release the medicinal liquid, and then extract it 2-3 times in the same way, and finally pour it out Medicinal dregs, this extraction method is inefficient and takes a long time, and has been replaced by a new method. For example, in recent years, some pharmaceutical factories have adopted the dynamic warming extraction method. The equipment includes percolators, multi-functional extraction tanks, etc. The extraction rate of active ingredients is relatively high, and the extraction process does no...
