example 1

[0026] Example 1 Extraction of Ephedra

[0027] According to the pre-determined process, first close the valves 27, 30, and 36, and put the crushed ephedra and 4 times the amount of sodium hydroxide alkali aqueous solution with pH 8.5 into the extraction container 16 through 11, 12, and the sodium hydroxide alkali aqueous solution After the n-octanol is in the appropriate position below the tube 34, n-octanol is injected again. When the n-octanol level is higher than the tube 34, the n-octanol flows into the concentration vessel 3 through the connecting tubes 34 and 42, and the n-octanol flows into the concentration vessel 3. Stop the injection of n-octanol after the surface is at a proper position below the nozzle 45 (this position is determined by the process). Close and seal the inlets 11 and 12, start the stirring devices 21 and 23, so that the solid materials and the sodium hydroxide aqueous solution can fully interact, and the valves 19 and 14 can be opened to appropriately...

[0032] Example 2 Extraction of Baicalin

[0033] According to the pre-determined process, the valves 27, 30 and 36 are closed first, and the crushed scutellaria and 95% ethanol solution are placed in the extraction container 16 through 11 and 12. The 95% ethanol solution flows into the concentration container 3 through the connecting pipes 34 and 42 , Stop the injection of 95% ethanol after the 95% ethanol liquid level is at an appropriate position below the nozzle 45 (this position is also determined by the process). Close and seal the inlets 11 and 12, start the stirring devices 21 and 23, so that the solid materials and the 95% ethanol solution can fully interact, and at the same time, the valves 19 and 14 can be opened to appropriately heat the extraction container to promote the alcohol solubility of the solid materials. The ingredients are fully eluted, and the temperature should be kept at 40°C to 60°C. Opening the valve 1 allows the heating medium to enter the jacket 44 ...

[0037] Example 3 Extraction of Astragaloside IV

[0038] According to the pre-determined process, the valves 27, 30 and 36 are closed first, and the crushed astragalus and 95% ethanol solution are placed in the extraction container 16 through 11 and 12. The 95% ethanol solution flows into the concentration container 3 through the connecting pipes 34 and 42 , Stop the injection of 95% ethanol after the 95% ethanol liquid level is at an appropriate position below the nozzle 45 (this position is determined by the process). Close and seal the inlets 11 and 12, start the stirring devices 21 and 23, so that the solid materials and the 95% ethanol solution can fully interact, and at the same time, the valves 19 and 14 can be opened to appropriately heat the extraction container to promote the alcohol solubility of the solid materials. The ingredients are fully eluted, and it is better to keep this temperature at 30°C to 50°C. Opening the valve 1 allows the heating medium to enter the j...

Abstract

The present invention provides a soluble component by a special liquid extracting in solid matters, or another soluble component by solution is separated from a soluble solution, and proceeding synchronous concentration to extracting solution at the same time. The invention has an extracting container, located in a feed inlet, a sealing lid on the extracting container, and a mixing device in the extracting container, and a taphole and an outlet on the extracting container. The device also has a concentrating container with a heating device, the upper of the concentrating container is set witha pipeline connected with the condenser, end of the condenser uses the inner of the extracting container of another pipeline, the outlet of the downstream is located above the 2 / 3 of the inner heightif the concentrating container.

Description

Technical field [0001] The invention relates to an extraction device, which can be used to extract components in solid substances that can be dissolved in a specific solution, and can also be used to separate components that are dissolved in one solution and can be dissolved in another solution. And can concentrate the extract simultaneously. The invention is particularly suitable for extracting specific components of traditional Chinese medicine. The invention includes an extraction container, a heating device arranged on the extraction container, a feeding port and a sealable cover on the extraction container, a stirring device located in the extraction container, and a liquid outlet and a slag outlet provided on the extraction container. Background technique [0002] At present, the commonly used extraction methods of traditional Chinese medicine include decoction, reflux, dipping, percolation, etc. New extraction technologies include supercritical extraction, ultrasonic meth...
