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.
Claims28
An extraction apparatus for extracting at least one constituent in a substance, comprising:
- an extractor for placing and mixing said substance and an extraction fluid, wherein said extraction fluid is a subcritical fluid, and said extractor comprises a temperature control unit, said temperature control unit is used to control temperature of said extractor for keeping said extraction fluid as said subcritical fluid and making said at least one constituent in said substance be dissolved in said extraction fluid;
- an extraction evaporator unit linked up with said extractor for receiving and heating said extraction fluid and said at least one constituent dissolved in said extraction fluid from said extractor to gasify said extraction fluid;
- an extraction separator linked up with said extraction evaporator unit for receiving and separating said at least one constituent and said gasify extraction fluid from said extraction evaporator unit;
- and
- an extraction condenser linked up with said extraction separator and said extractor for receiving and liquefying said gasified extraction fluid from said extraction separator and sending said liquefied extraction fluid to said extractor, wherein said extractor, said extraction evaporator unit, said extraction separator and said extraction condenser are operated under constant pressure.
An extraction apparatus for extracting at least one constituent in a substance, comprising:
- an extractor for placing said substance and an extraction fluid, wherein said extraction fluid is a subcritical fluid, and said at least one constituent in said substance is dissolved in said extraction fluid;
- a discharge pipe linked up with said extractor for receiving said extraction fluid and said at least one constituent dissolved in said extraction fluid from said extractor, wherein said discharge pipe accommodates a discharge pump, valve or additional heating system.
- an extraction separator linked up with said discharge pipe for receiving and heating said extraction fluid and said at least one constituent dissolved in said extraction fluid from said discharge pipe to gasify said extraction fluid and separate said at least one constituent and said gasified extraction fluid;
- an extraction condenser linked up with said extraction separator for receiving and liquefying said gasified extraction fluid from said extraction separator, wherein said extractor, said extraction evaporator unit, said extraction separator and said extraction condenser are operated under constant pressure;
- and
- a circulation pipe linked up with said extractor and said extraction condenser for receiving said liquefying extraction fluid from said extraction condenser and sending said liquefied extraction fluid to said extractor, wherein said circulation pipe comprises a circulation pump, a valve or a heater to preheat the extraction fluid entering the extractor.
An extraction apparatus for extracting at least one constituent in a substance, comprising:
- an extractor for placing said substance and an extraction fluid, wherein said extraction fluid is a subcritical fluid, and said at least one constituent in said substance is dissolved in said extraction fluid;
- a needle valve linked up with said extractor for receiving said extraction fluid and said at least one constituent dissolved in said extraction fluid from said extractor for adjusting flow rate of said extraction fluid and said at least one constituent dissolved in said extraction fluid;
- an extraction separator receiving and heating said extraction fluid and said at least one constituent dissolved in said extraction fluid from said needle valve to produce said gasified extraction fluid and separate said at least one constituent and said gasified extraction fluid, wherein pressure of said gasified extraction fluid is adjusted by flow rate of said extraction fluid;
- and
- an extraction condenser linked up with said extraction separator and extractor for receiving and liquefying said gasified extraction fluid from said extraction separator, and said liquefied extraction fluid is sent to said extractor.
An extraction method, comprising steps of:
- performing a mixing process to mix a first extraction fluid, which is a subcritical fluid, and a substance comprising a first constituent, and dissolving said first constituent in said first extraction fluid;
- performing a heating process to heat said first extraction fluid and said first constituent dissolved in said first extraction fluid to gasify said first extraction fluid;
- performing a separating process to separate said gasified first extraction fluid and said first constituent;
- performing a liquefying process to liquefy said gasified first extraction fluid;
- and
- repeating at least one more said mixing process, said heating process, said separating process and said liquefying process.
