Chinese medicine extractor technology is a separation technology developed in recent decades. The basic principle of separation is to use the difference in molecular weight of chemical components to achieve separation. In the application of traditional Chinese medicine, it mainly filters out bacteria, microparticles, macromolecular impurities (colloid, tannin, protein, polysaccharide), etc. or decolorizes. Compared with the traditional alcohol flow process, the process eliminates the multiple processes in the alcohol precipitation process, and achieves the purpose of removing impurities, and still maintains the traditional Chinese medicine boiling and compound compatibility, has the advantages of easy drying and low hygroscopicity, and adds Less agent, saving a lot of ethanol and corresponding recycling equipment, shortening production cycle, reducing process and personnel, saving heat and so on.

Traditional method:

Traditional extraction methods for traditional Chinese medicine treatment include water decoction, impregnation, percolation, modified gelatin, reflux, solvent extraction, steam distillation and sublimation. Among them, water decoction is a commonly used method. The solvent extraction method is a widely used method. It is based on the solubility of various active ingredients in the Chinese herbal medicine, and the solvent having a large solubility to the desired component and having a small solubility to other components is used to dissolve the desired active ingredient from the medicinal material. An extraction method.

The steam distillation method is an extraction method in which the active ingredient in the Chinese medicinal material can be distilled without steaming. (Mainly used for the extraction of aromatic water and volatile oil). The principle of this method is the Dalton principle: the total vapor pressure of a liquid mixture that is insoluble or chemically in each other, equal to the sum of the saturation pressures of the components at that temperature. (Although the boiling point of each component itself is higher than the boiling point of the mixed solution, when the total partial pressure is equal to atmospheric pressure, the liquid mixture starts to boil and is distilled.) The sublimation solid material directly turns into a vapor state after being heated, and after cooling, Solidification into the original solid material, known as sublimation, (such as the extraction of paeonol) operating principle and distillation method. The disadvantage is that the active ingredient is lost too much, especially the water-insoluble component; during the extraction process, the organic solvent may interact with the active ingredient to make it lose its original effective use; the non-active ingredient cannot be removed to a large extent, and the concentration rate is not high enough; In addition to the active ingredients in the liquid, there are often many impurities, and there are still a small amount of fat-soluble components, which is disadvantageous for refining; high-temperature operation causes a large amount of decomposition of heat-sensitive active ingredients.

Principle of Chinese medicine extractor : Chinese medicine extractor plays different roles in the extraction process due to the cavitation and pulverization of ultrasonic waves, so that it has:

1. Strengthen penetration and shorten extraction time

The traditional soaking extraction method infiltrates and infiltrates, so that the solvent enters the cell tissue from the capillary and the cell gap, and dissolves, so that the chemical components inside the substance enter the solvent, causing the concentration difference inside and outside the cell to promote the composition from the high concentration solution to the low concentration. The agent spreads. When the plant material is subjected to ultrasonication in a solvent, the cavitation effect caused by the ultrasonic wave causes the solvent to collide with the cavitation bubble instantaneously generated by the ultrasonic wave, and quickly penetrates into the internal cells of the substance to accelerate the solvent and the medicinal material. The active ingredients penetrate and dissolve each other, so that the chemical components dissolve rapidly into the solvent under the action of ultrasound. The Chinese medicine extractor accelerates the solvent into the cells and rapidly transfers the chemical components in the cells into the solvent, causing a difference in concentration inside and outside the cells, prompting the chemical components to diffuse from the high concentration solution to the low concentration solution, and the Chinese medicine extracting machine is greatly accelerated. Extraction process. By separating, the purpose of extracting the palm component is achieved.

2. Break the cell wall and increase the rate

Extracting chemical components from plant matter, the Chinese medicine extractor not only accelerates the mutual penetration of solvent and substance, but also observes the electron photomicrograph, and finds that the Chinese medicine extractor is carried out by the cavitation process generated by ultrasonic vibration, and The energy generated by the energy released by the cavitation bubble collapses, causing the cell wall in the material to rupture, allowing the solvent to directly enter the interior of the cell, allowing the subsequent contents (components) in the cell to be directly transferred under ultrasound. Into the solvent. The various chemical components in the intracellular protoplasts are replaced by a solvent, so that the Chinese medicine extractor can completely extract the components contained in the substance cells in a short period of time. Compared with the traditional extraction method, the proposed chemical composition of the substance is increased.
