Several extraction methods of traditional Chinese medicine extraction and concentration tank

The extraction and concentration tank of Chinese medicine can extract the essence of traditional Chinese medicine It is an extraction equipment which is often used in medicine and chemical industry, and is especially suitable for the extraction of the components contained in plant products Do you know the extraction method of the extraction equipment? How do they extract things? Extraction method 1: decocting method: it refers to placing the processed medicinal materials in the extraction tank, adding a proper amount of water to heat and boil, so that the effective ingredients of the medicinal materials diffuse to the water to form the leaching solution, pouring out the leaching solution, then adding water to decocting for two or three times, and discarding the dregs of the medicine to obtain the leaching solution for extracting the effective ingredients The operation of decocting and extracting in the extraction and concentration tank of traditional Chinese medicine: 1 The general processing of appropriate amount of water should be less than 10% of the traditional Chinese medicine 2 The temperature of heating should be high at the beginning After boiling, the temperature can be reduced to make the liquid slightly boil 3 The time of decocting depends on the hardness and granularity of the pieces The decocting time for the pieces with high hardness and large granularity is slightly longer, generally speaking, the decocting time is 20-40min after boiling; the times of decocting mainly depend on the types of pieces, such as ginseng and deer antler and other tonic decocting time can be longer, more times, generally two times (for details, please refer to the introduction of Tianyu ultrasonic "reasons for low vacuum during the operation of extraction and concentration equipment") For the extraction method of Chinese medicine extraction and concentration tank, please pay attention to the following items: 1 The medicinal materials should be processed pure medicinal materials 2 The amount of water added shall be 6-8 times of the amount of medicinal materials 3 It should be heated to boiling before timing Extraction method 2 of Chinese medicine extraction and concentration tank: reflux extraction method: the organic solvent is used for heating extraction, when heating extraction, the solvent is evaporated, and then flows back to the extractor after condensation, so repeatedly until the extraction method is completed, the reflux heating device shall be used to avoid the loss of solvent volatilization Operation process: medicinal materials → smashing → soaking and wetting → refluxing → solvent recovery → concentrated extract Method 3: percolation extraction is a method of extracting the effective components in the flowing process through the contact between the solvent and the medicine in the percolation container containing the medicine with high humidity The extracted solution is called "percolation solution" Operation method: 1 Moistening: mix well with the prepared solvent, and the medicine will fully expand after absorbing the solvent 2 Barrel filling: after the medicine is wet for a period of time, it is put into the percolation barrel (or multi-functional extraction tank) 3 Immersion: slowly add the solvent after filling the barrel to a height of several centimeters above the drug surface, and place it on the cover for 24-48 hours 4 Percolation: when the immersion time is up, slowly release the lixivium, and add solvent to the powder in time It should be noted that: according to the process of multi-functional extraction tank, herbal medicine will form a cold pile at the bottom of the extraction tank, reduce the extraction amount of effective ingredients, and cause waste of herbal medicine.
