Embodiment Construction

[0024] see figure 2 , is a block connection diagram of the first embodiment of the extraction device of the present invention. The extraction device 10 can extract at least one component from a substance. The extraction device 10 includes an extraction tank 11 , an extraction evaporation unit 13 , an extraction separator 17 and an extraction condenser 15 . The extraction tank 11 is used for mixing the substance and the extraction fluid, wherein the extraction fluid is a subcritical fluid.

[0025] A subcritical fluid (or primary critical fluid) is a liquefied gas. When the temperature is higher than the boiling point and lower than the critical point, the gas can enter the liquid state by increasing the pressure to form a subcritical fluid. Compared with using supercritical fluid as the extraction fluid, the advantage of using subcritical fluid as the extraction fluid is that the extraction equipment and extraction operations can be operated and performed under relatively ...

Abstract

The present invention relates to an extraction apparatus for extracting at least one constituent in a substance. The extraction apparatus comprises an extractor, an extraction separator and an extraction condenser. The extractor is used to mix the substance and an extraction fluid, wherein the extraction fluid is a subcritical fluid. The extraction separator is connected to the extractor for receiving and heating the extraction fluid to gasify the extraction fluid and to separate the constituent and the gasified extraction fluid. The extraction condenser is connected to the extraction separator and the extractor for receiving and liquefying the gasified extraction fluid from the extraction separator and sending the liquefied extraction fluid to the extractor.

Description

[0001] The present invention is based on the content of the U.S. provisional application filed on September 07, 2015, the application serial number is 62 / 215,104, and the application is currently pending. technical field [0002] The present invention relates to an extraction device and an extraction method, in particular to an extraction device and an extraction method for extracting at least one component from a substance through an extraction fluid in a primary critical fluid state. Background technique [0003] see figure 1 , is a three-phase diagram of a substance. As shown in the figure, a substance can usually exist in three forms: gas phase, liquid phase and / or solid phase according to different temperature and pressure conditions. figure 1 Point A in is the triple point of the substance, and point C is the critical point. The temperature at point A is T1, and the pressure is P1. Under the temperature and pressure conditions at point A, the three phases of matter c...
