Working principle and working mode of extraction equipment

The working principle of the extraction equipment countercurrent method is: the medicine and the solvent move in the opposite direction in the extraction container, continuously and fully contact extraction The equipment is a continuous and dynamic countercurrent extractor Its extraction principle is to use the heating method with strong microwave penetration to make the extraction faster and more convenient The continuous countercurrent extraction equipment is a combination of dynamic extraction, countercurrent extraction and decoction extraction While retaining the advantages of many traditional processes, it creates many advantages that these traditional processes cannot achieve: fast extraction speed, sufficient extraction of effective components, high extraction yield, less solvent consumption, high concentration of liquid medicine, reduction of evaporation and concentration and other subsequent processing technologies, medicine in drum, etc The moving speed of the material particles can be adjusted, so that the extraction time can be adjusted according to the characteristics of the medicinal materials The medicinal materials can be extracted in a mild dynamic environment The heating temperature is low, and the effective ingredients are less damaged, so that the impurity content in the medicinal solution is less, which belongs to continuous production and has large processing capacity The countercurrent extraction equipment works in a forward feed and reverse feed mode, and the flow of materials and water is a reverse continuous dynamic flow, which can keep the relative motion of herbs and solvents, and make the concentration diffusion and renewal of materials and liquid continuously, so as to ensure the fast leaching speed of materials and liquid At the same time, the pipeline extraction equipment solves the problems existing in the traditional countercurrent extraction equipment, such as the material can not be stirred, the extraction is not uniform, the sealing performance is not good, the organic solvent can not be used for extraction, the internal mechanical components are worn, causing pollution and so on.
