Traditional Chinese medicine purification and solvent recovery system

The utility model relates to the technical field of traditional Chinese medicine purification, in particular to a traditional Chinese medicine purification and solvent recovery system which comprisesan extraction tank, a separation device, an MVR evaporation and concentration device and a solvent recovery device which are connected in sequence. The method comprises the following steps: soaking traditional Chinese medicinal materials in water or an alcohol solvent in an extraction tank to extract effective components of the traditional Chinese medicinal materials; filtering medicine residues through a primary filter to obtain an extracting solution; separating effective components of the traditional Chinese medicine from the extracting solution through a nanofiltration filter; the light-phase water or alcohol solution enters an MVR evaporation and concentration device for evaporation and concentration, a concentrated solution enters a concentrated solution tank, heat enthalpy of evaporated solvent vapor is inc
