DECOMPRESSION EXTRACTION DEVICE FOR EXTRACTING CHINESE MEDICINE

摘要

A decompression extraction device is used for extracting Chinese medicine in vacuum and lower boiling point condition. The device comprises an extracting tank; a condenser, which connects with the extracting tank in one end through a mist eliminator and connects with a feed inlet of the extracting tank in the other end; and a cooler. There is a liquid receiving tank between the cooler and the feed inlet of the extracting tank, which is used for maintaining vacuum state in the extracting tank and keeping the solvent going back to the extracting tank after through the condenser. Compared to the prior art, the present invention can maintain a given vacuum degree and lower boiling point condition all the time as extracting, which not only advance the efficiency, but also improve the product quality.
