Microwave countercurrent extraction machine is used for the extraction of active ingredients and pigments etc. of natural Chinese herbs, which has extremely wide use in medical, chemical and health food industries. Countercurrent method is: herbs and solvents in the leaching container along the opposite direction of the movement, continuous and full contact extraction of a million law. Equipment for efficient continuous dynamic countercurrent extraction machine, the extraction principle is: the use of microwave penetrating heating, so that the extraction is faster and more convenient. Continuous countercurrent extraction equipment is a combination of dynamic extraction, countercurrent extraction, decoction extraction process, while retaining the advantages of a variety of traditional processes, to create a number of advantages that these traditional processes can not be achieved: fast extraction, extraction of the active ingredient extraction, extraction of high yield, low solvent consumption, high concentration of the liquid, reducing the evaporation and concentration of the subsequent processing art, the speed of movement of the particles of the herbs within the drum can be adjusted, so that the extraction time can be adjusted according to the characteristics of the herbs. According to the characteristics of the herbs to adjust the length of the extraction time, herbs in a mild dynamic environment for extraction, lower heating temperature, less destruction of the active ingredients, so that the liquid impurity content is less, belongs to the continuous production, processing capacity.
