More attention should be paid to the advantages of equipment in the development stage of multi-functional extraction tank of traditional Chinese Medicine

[product information of multifunctional extraction tank is a kind of closed intermittent extraction equipment with adjustable pressure and temperature, which is widely used in traditional Chinese medicine industry Because the effective ingredients in traditional Chinese medicine need to be extracted to give full play to the curative effect, the multi-functional extraction tank actually provides great help for the extraction of traditional Chinese medicine The author has learned that the extraction process of multifunctional extraction tank generally has four main control links , heating operation of extraction tank When water is extracted, steam is first introduced for heating When the temperature reaches the extraction temperature, then indirect heating is conducted to the interlayer to maintain the temperature in the tank within the specified range If alcohol is used for extraction, all of them are indirectly heated with interlayer steam Second, circulation operation of extraction tank includes forced circulation and reflux circulation In the aspect of forced circulation, in the extraction process, a pump is used for forced circulation of the liquid medicine, that is, the leaching liquid is discharged from the drain port at the lower part of the tank body, filtered by the pipeline filter, and then pumped back to the tank body by the water pump In order to speed up the relative movement between solid and liquid, the floating herbs can be dissolved quickly In the solvent, so as to enhance the convection diffusion and leaching process, improve the leaching efficiency During the extraction process, a large amount of steam generated from the reflux cycle is condensed from the steam outlet through the foam trap to the heat exchanger, then cooled into the cooler, and the liquid is reflued to the extraction tank Loop like this until extraction is terminated Third, the discharge operation of the extract After extraction, the liquid medicine is discharged from the liquid drain of the tank, filtered by the pipeline filter, and then pumped to the concentration section for concentration Fourth, the operation of extracting volatile oil The liquid medicine vapor condenses through the condenser, and then directly enters the oil-water separator for oil-water separation after being cooled by the cooler At this time, the valve channel of the cooler must be closed The separated volatile oil is released from the oil outlet, and the perfume comes back from the water pipeline to the extraction tank Thanks to the multi-functional extraction tank, the production of traditional Chinese medicine in the extraction process has become much smoother According to the introduction of relevant experts, the reflux extraction of the functional extraction tank leads to a large amount of feeding The dosage can be doubled compared with the conventional extraction In addition, the multi-functional extraction tank process has good adaptability It can operate water extraction and alcohol extraction by using atmospheric pressure, negative pressure and positive pressure processes, especially the low-temperature extraction, concentration and high paste collection rate of heat sensitive materials The multi-functional extraction tank can also save time The extraction and concentration are completed in one step The multi-functional extraction tank of traditional Chinese medicine adopts a return flow rate that is twice as large as the conventional one The whole process only takes 4-6 hours, and the energy consumption is reduced Under the background of promoting energy conservation and environmental protection, the multi-functional extraction tank of traditional Chinese medicine uses secondary steam as the heat source to extract and concentrate at the same time, and the temperature of reflux condensate is close to the boiling temperature in the extraction tank; moreover, polyurethane foam is used as the insulation layer, and the temperature and vacuum are controlled randomly The multi-functional extraction tank can save more than 50% steam For a long time, traditional Chinese medicine is the treasure of the Chinese nation, which has made a positive contribution to the health and development of human life As an essential equipment in the production process of traditional Chinese medicine, the multi-functional extraction tank has its advantages and characteristics, which are constantly helping the traditional Chinese medicine industry Advanced technology is the prerequisite of production efficiency The author understands that in recent years, the multi-functional extraction tank of traditional Chinese medicine has experienced many technological improvements Through theoretical analysis of practical experience, the designers continue to improve and innovate in the structure of equipment The industry believes that the multi-functional extraction tank of traditional Chinese medicine has become a mature stage of development, paying more attention to the advantages of equipment However, in order to achieve higher results, enterprises related to multi-functional extraction tanks of traditional Chinese medicine should further improve the level of technological innovation, actively develop new products, and provide greater momentum for the whole traditional Chinese medicine industry.
