At present, with the advancement of traditional Chinese medicine extraction technologies, the CWL-M type centrifugal extractor is widely used in extraction processes to obtain Paeonia lactiflora extract by leveraging these technologies. Paeonia lactiflora extract is derived from the plant Paeonia lactiflora belonging to the Ranunculaceae family, and there are various methods for its extraction; it is a natural extract obtained through refining, concentrating, and drying this plant. Because its main component is paeoniflorin. Soluble in methanol, soluble in ethanol. Stable in acidic conditions, unstable in alkaline conditions. It has good thermal stability. Therefore, ethanol can be used as an extractant to extract traditional Chinese medicines using specialized extraction equipment.
The extraction process of Paeonia lactiflora using the CWL-M type centrifugal extractor, a device for traditional Chinese medicine extraction: After Paeonia lactiflora is crushed, acidified, and extracted, paeoniflorin is mainly dissolved in the aqueous extract； After pH adjustment, paeoniflorin is released from the water, and then extracted using ethanol; at this point paeoniflorin moves into the ethanol, after which the subsequent purification and crystallization steps are carried out. During the ethanol extraction process, the traditional method involves batch stirring extraction, where gravity is used to separate the phases and the two phases are then separated manually. This intermittent approach is rather cumbersome and results in a longer production cycle. By using the new CWL-M type centrifugal extractor, not only can the aforementioned disadvantages be overcome, but it also enables continuous production in the extraction stage, more complete phase separation, less ethanol usage, and a higher extraction efficiency.
