Abstract
The present invention provides a portable extraction device for extracting at least one constituent from a substance by an extraction fluid. The extraction device comprises at least one pump, an extractor, an evaporator, and a condenser. The substance and the extraction fluid are placed and mixed in the extractor. The extraction fluid is a subcritical fluid. The constituent in the substance will be dissolved in the extraction fluid under a predetermined pressure and temperature. The evaporator receives the extraction fluid including the constituent from the extractor, and heats the extraction fluid including the constituent to gasify the extraction fluid and separate the constituent from the gasified extraction fluid. The condenser receives the gasified extraction fluid via a first pipe, liquefies the gasified extraction fluid, and transmits the liquefied extraction fluid to the extractor via a second pipe. The extractor, the evaporator, and the condenser are operated under constant pressure.
