Patent ID: 10016700

Abstract:
A multifunctional continuous phase transition extraction apparatus comprises an extraction system, a desorption system and a solvent recovery system. The extraction system comprises a first heat exchanger and an extraction tank. The desorption system comprises a second heat exchanger, a first desorption tank, a second desorption tank, a first purification column and a second purification column. The solvent recovery system comprises a first condenser, a second condenser, a first solvent tank and a second solvent tank. Two extraction loops can be formed in the present invention. During the overall extraction process, the phase transition process of the extracting agent is real-time and continuous. The extracting agent goes through continuous phase-transitions and is cyclically re-used. The overall process is operated in an airtight and low-pressure condition, and is multifunctional, safe, reliable, and suitable for the extraction for most natural products.
