The unit is mainly composed of the dynamic extraction tank,evaporation and concentration device and process piping and other components, sets dynamic hot reflux extraction, vacuum concentration, solvent recovery as one integration, and can carry out continuous and synchronization of extraction and concentration in airtight state, solvent steam produced during the concentration backflows to the extraction tank after being condensed, and can use the second steam to reheat the material in extraction for thermal circumfluence dynamic extraction, applicable to water and organic solvent with normal and 60 ¡æ or so of the low temperature of extraction for the traditional Chinese medicine, biological, food, light industries, it has less investment, high efficiency, energy saving and the other obvious advantages.
