Description
Technical field
The utility model relates to a kind of extraction equipment, and particularly a kind of is extraction and recovery equipment for supercritical fluid with carbon dioxide.
Background technology
At present health food on the market and maintenance, cosmetics much have the active component adding and extracted by the every material of the Nature, and extract the method for active component, mainly include: the mode such as steam distillation and organic solvent extraction, wherein steam distillation is mainly used in obtaining the product such as essential oil or essence dew, aforementioned steam distillation often has moisture content to exist at high temperature, and this not only easily causes fragrance ingredient unstable, and heat-sensitive ingredients often has the problems such as decomposes, hydrolysis and water-soluble effect to occur, and thus reduces the quality of product; And though organic solvent extraction can reduce Extracting temperature, there is the shortcoming that dissolvent residual and low boiling point component escape; Therefore, in order to improve aforesaid problem, have at present with the supercritical fluid extraction close to ambient operation to replace traditional extraction mode.
Current supercritical fluid extraction mode mainly can divide into following three kinds:
1, static extracting mode: mainly supercritical solvent pressurization enclosed to do after extraction tank and leave standstill extraction a period of time, reaches until system and to open valve after balance again and to be gone out by extract and simultaneously and separated from solvent.
2, dynamic extraction mode: be mainly that the entrance of extraction tank installs a back-pressure controller additional to keep the pressure of extraction tank, and control supercritical fluid and flow through extraction tank with certain flow velocity, constantly carry out continuous extraction with fresh supercritical fluid.
3, static--dynamic extraction mode: key step is first do the static extracting of a period of time, then carries out dynamic extraction.Thus, extraction efficiency can be higher and the consumption of fluid can be fewer than the mode of dynamic extraction than static extracting.

(2), the low scope making operating temperature can maintain relative low temperature of critical-temperature of carbon dioxide, the destruction to heat-sensitive material can be reduced.
(3), the organic substance of supercritical carbon dioxide to much lower polarity has good solvability, and its solvability can very easily via the change of pressure and temperature, or (modifier or co-solvent adjusts to add a small amount of dressing agent.
(4), carbon dioxide nontoxicity, non-corrosiveness, non-combustible, chemical stability is good, can reduce the danger of preparation process.
(5), carbon dioxide source obtains easily and tool high volatility, and be gas at ambient pressure, step-down effectively by CO2 and product separation, need only can save the separated from solvent step that common solvent extraction is tediously long afterwards after extraction.
(6), because carbon dioxide is originally as nonpolar molecule, because to low polarity, (lipophilicity solute can show higher affinity, and for the larger molecule one of some polarity with polar group (as the compound of an OH, a COOH etc., its solvability and extraction efficiency will reduce, (modifier increases the solubility of carbon dioxide to polar solute, to improve the extraction efficiency of polar solute now can to work as dressing agent by a small amount of polar organic solvent of interpolation.
