Enhance the advantages and make up the shortcomings of the extraction and concentration equipment to make the quality of traditional Chinese medicine more stable

[product information of China Pharmaceutical network] there are many kinds of extraction and concentration equipment for traditional Chinese medicine Due to the different processes adopted by each manufacturer, there are also differences in the combination of extraction and concentration equipment Although there are differences, there are still many advantages in the extraction and concentration equipment, which also provide constant protection for the safe production of drugs Extract concentration is a process, is also a very important link in the traditional Chinese medicine industry, and plays an important role in the pharmaceutical field With the steady improvement of extraction and concentration technology, the market of extraction and concentration equipment is growing, and many new equipment are gradually emerging Some people in the industry have summarized the advantages of the extraction and concentration equipment First of all, the lower bottom cover of the extraction and concentration equipment adopts the push groove wide tooth self-locking device First, the lower cover is compressed by the air cylinder, and then the push-pull inclined ring gear intersects the two flanges to push more and more tightly The pressure in the experimental tank reaches 0.3MPa, without any leakage of material liquid, which is safe, reliable, easy to use and high efficiency There are two ways to connect the bottom cover and the liquid outlet: one is fixed by hard stainless steel; the other is liquid outlet from the bottom wall, both of which have no leakage or fracture, so as to ensure the safety of production Secondly, the tank body adopts the straight cylinder type, the lower jacket is added at the lower part, and the bottom wall liquid discharging method is adopted: pump from the extraction tank The medicine liquid is extracted from the inner tank belly through the filter screen, and then is sprayed upward from the bottom wall through the circular tube of the filtering studio to form a forced countercurrent circulation, which pushes the medicine liquid to fully rub and elute with the medicine liquid from the bottom up, maintains a high concentration difference, accelerates the extraction speed, shortens the extraction time, and improves the efficiency Then, a ring-shaped filter screen is added at the bottom of the tank to increase the area of the filter screen, so that the filter screen is not easy to be blocked At the same time, the device does not need to stir the pulp, which can avoid the damage of the medicinal fiber caused by the mixing of the pulp leaves and the increase of the fiber fragments, which will block the filter screen and the pipe At the same time, the device uses the pump to spray upward and force the counter current circulation, which plays the role of mixing After that, forced foaming was used in the extraction and concentration equipment The foam pressing movable orifice plate is fixed on the inner wall of the upper part of the tank body, and the hinged movable plate is used When adding medicinal materials, the movable half cover is opened upward, and the movable half cover is covered downward after the medicinal materials are added In fact, this solution has solved the phenomenon that the original old type extraction tank can extract light medicinal materials, the phenomenon of foam rising and running, and the phenomenon of blockage of small and light medicinal herbs into pipes of the cooler Although the extraction and concentration equipment has many advantages and advantages, it also has many disadvantages With the improvement of GMP standard, the requirements for the extraction and concentration equipment of traditional Chinese medicine are also increasing So, how can we solve the "short board" of the extraction and concentration equipment and make the quality of traditional Chinese medicine concentration more stable? The author understands that the online anti hanging wall three-phase flow concentrator not only has the advantages of natural external circulation two-phase flow concentrator, but also overcomes its shortcomings At present, the new concentrator is promising in the market Specifically, the structure of the new technology device of the online anti hanging wall three-phase flow concentrator is similar to that of the natural external circulation two-phase flow concentrator The basic principle is to add a certain amount of physiological inert solid particles into the natural external circulation two-phase flow concentrator of Chinese medicine extraction liquid to form the vapor liquid solid three-phase flow Through the solid particles in the fluidization state, the fluid layer on the inner wall of the heating pipe of the concentrator is constantly disturbed, so as to realize the purpose of online scale prevention and enhanced evaporation concentration process Some manufacturers said that with the application of on-line anti hanging wall three-phase flow concentrator, the production efficiency of traditional Chinese medicine extract concentration has been greatly improved, and the concentration quality will become more stable.
