Abstract

See full text

Continuous extraction units (CEUs) are constructed that allow switching of extraction chambers (ECs) that contain extractable material (EM) and extract solution. Extraction chambers can be removable and replaceable, where the CEU has a fluid flow portion and a liquid transfer portion. Quick-connect valves allow exchange of ECs in the CEU while under flow without solvent loss. Alternatively, the CEU employs pairs of ECs where a first EC at equilibrium partitioning of an extract solution drains to an expansion chamber (EXC) with an expansion valve (EV) and a heat transfer tube situated proximal to or shared with a solvent condenser (SC) to form of a double phase change heat exchanger (HE). Solvent from the SC fills a paired EC containing EM. A second pair of ECs has a first EC with EM and solvent establishing equilibrium and a second EC that is emptied of spent EM, filled with fresh EM, and readied to receive solvent.
