    [product information of China Pharmaceutical network] extraction and concentration is a key link in the production of traditional Chinese medicine The requirements of extraction and concentration in traditional Chinese medicine industry are strict, especially in the current situation that the quality of traditional Chinese medicine is questioned In order to do a good job in the source production, traditional Chinese medicine enterprises should not only take traditional Chinese medicine as the breakthrough point, but also take pharmaceutical equipment as the breakthrough point to ensure the quality of traditional Chinese medicine products Therefore, the extraction and concentration equipment has become one of the products that many Chinese medicine enterprises are competing to buy first However, at present, there are many kinds of extraction and concentration equipment in the market, the quality is uneven, and the technical level is high or low For this, how should Chinese medicine enterprises choose satisfactory extraction and concentration equipment? Some extraction and concentration equipment manufacturers tell the author: "when customers purchase equipment, we usually tell them which kinds, their respective performance and characteristics." Then, the customers will choose according to their own needs, and we will also make customized production for them according to their requirements " The so-called extraction equipment is a solid-liquid extraction equipment which uses solvent (water or other solvent) to separate the effective components in solid materials There are static extraction tank, ultrasonic extraction equipment, microwave extraction equipment and supercritical extraction equipment Taking ultrasonic extraction equipment as an example, ultrasonic extraction equipment is a kind of extraction equipment which can accelerate the extraction of effective ingredients by using the cavitation effect of ultrasonic In general, the thermal effect, mechanical effect and cavitation effect of ultrasound are interrelated, so we can control the frequency and intensity of ultrasound, highlight one effect, reduce or avoid the other effect, so as to improve the extraction rate of effective ingredients According to some manufacturers, the advantages of ultrasonic extraction equipment are not only short time, low temperature and high yield, but also reasonable production process, process and parameters for large-scale production For another example, supercritical extraction equipment, the author learned that supercritical extraction has the characteristics of distillation and liquid-liquid extraction, and can play a role in the process of extraction, the difference between the volatility of the separated substances and the difference between the molecular affinity Therefore, supercritical extraction equipment has the characteristics of high efficiency, fast speed and low energy consumption In the pharmaceutical industry with the trend of environmental protection, supercritical extraction equipment is more suitable for the separation of heat sensitive substances Concentration equipment generally has multi effect concentrator, single effect concentrator, etc The multi effect concentrator uses the secondary steam generated by the primary evaporation concentration as the heat source for the next concentration, and the primary concentrated solution enters the next concentration through the series pipeline However, the multi effect concentrator has many residues, difficult to clean, high concentration temperature and more loss of heat sensitive components The single effect concentrator adopts the combination of external heating natural circulation and vacuum negative pressure evaporation, with fast evaporation speed, low temperature concentration under reduced pressure, large concentration ratio and convenient cleaning According to the performance and characteristics of the above equipment, users can choose according to the actual requirements With the steady improvement of extraction and concentration technology, the market of extraction and concentration equipment of traditional Chinese medicine is becoming more and more important, and many new equipment are gradually emerging The author has learned that the new extraction and concentration equipment of traditional Chinese medicine on the market has many advantages For example, the feed liquid will not leak, is safe and reliable, is convenient to use, and has high efficiency; the connecting hose between the bottom cover and the liquid outlet is mainly fixed by hard stainless steel and discharged by the bottom wall For another example, the tank body adopts the straight cylinder type, the lower jacket is added at the lower part, and the bottom wall liquid outlet mode is adopted This method not only keeps the high concentration difference, speeds up the extraction speed, shortens the extraction time and rate, but also makes the pot medicine loose and easy to be used in the next process In addition, a ring-shaped filter screen will be added at the bottom of the tank of the extraction and concentration equipment to increase the area of the filter screen, so as to avoid the blockage of the filter screen and the pipe due to the destruction of the fiber and the increase of the fiber fragments caused by the mixing of the pulp and leaves At the same time, the extraction and concentration equipment tank also uses the pump to spray upward and force countercurrent circulation, which plays a role of mixing All in all, users still need to consider when choosing extraction and concentration equipment, not only considering the performance of the equipment and their own needs, but also combining the relevant services and brand influence of the equipment manufacturers In addition, at the time of transformation and upgrading of pharmaceutical machinery industry, extraction and concentration manufacturers should also keep pace with the industry, actively innovate, and contribute to the innovation and development of pharmaceutical machinery industry and traditional Chinese medicine industry.
