Subcritical Curcumin Extraction Plant
Technical principle of curcumin extraction
Under normal temperature and certain pressure, use liquefied sub-critical solvent to process the raw material. This process is called counter-current extraction.Extraction liquid goes through vacuum evaporation at normal temperature, which brings solvent gasification. And the gasified solvent is separated with curcumin components. Then curcumin extract is obtained. At normal temperature, extracted residual raw material will be vacuum evaporated to recover the solvent and get another product. Gasified solvent is compressed or liquefied for further recycling. The whole process is undertaken at normal or low temperature, which doesn’t cause any damages to thermal sensitivity of curcumin. Which is the biggest highlight of curcumin extraction by sub-critical solvent technology. (You may also want to Extract Lycopene from Tomato)
When the solvent gasifies from raw material, it need to absorbs heat. For sub-critical solvent curcumin extraction plant, the heat exchange of gasification and liquefaction saves energy consumption. Theoretical calculation and practices have proved that required energy for evaporation of solvent of extract liquor is only one-tenth of conventional solvent evaporation that uses steam energy.
Technological process of curcumin extraction plant
- The raw material of curcumin should be pretreated into powder or small pieces. Then, pretreated material will be loaded into the extraction pot.
- Pour the solvent into extraction pot for countercurrent extraction
- Liquid extract from extraction pot is pumped into evaporation system
- Connect intakeports of extraction pot and compressor, and the residual solvent within residual material is gasifying, then come into compressor. Through compressing, liquefaction and condensation, the solvent is saved for recycling. And the extraction slag is discharged out from the sub-critical solvent system.
- Liquid extract goes into evaporation system, and the solvent is separated from extract through vacuum evaporation.
- Solvent will be recycled after compression and liquefaction. And, the extract is discharged from evaporation system.
