超臨界萃取設備可以分為兩種(zhong)類(lei)型(xing),一(yi)種(zhong)是研究(jiu)分析型(xing),主要(yao)應用(yong)于(yu)小(xiao)量物(wu)質的(de)分析,或為生產提供數(shu)據(ju)。另一(yi)種(zhong)是制備生產型(xing),主要(yao)是應用(yong)于(yu)批量或大(da)量生產。
超臨界(jie)萃取設備從功(gong)能(neng)上大(da)體可分為八部分:萃取劑(ji)供(gong)應(ying)系(xi)(xi)統(tong)(tong),低(di)溫系(xi)(xi)統(tong)(tong)、高壓系(xi)(xi)統(tong)(tong)、萃取系(xi)(xi)統(tong)(tong)、分離(li)系(xi)(xi)統(tong)(tong)、改(gai)性(xing)劑(ji)供(gong)應(ying)系(xi)(xi)統(tong)(tong)、循環系(xi)(xi)統(tong)(tong)和計算(suan)機(ji)控制系(xi)(xi)統(tong)(tong)。具體包括二氧化(hua)碳(tan)注(zhu)入泵、萃取器、分離(li)器、壓縮機(ji)、二氧化(hua)碳(tan)儲(chu)罐、冷水機(ji)等設備。由于萃取過(guo)(guo)程(cheng)在高壓下進行(xing),所以對(dui)設備以及整個(ge)管路(lu)系(xi)(xi)統(tong)(tong)的耐壓性(xing)能(neng)要求較高,生產過(guo)(guo)程(cheng)實現(xian)微機(ji)自(zi)動(dong)監控,可以大(da)大(da)提高系(xi)(xi)統(tong)(tong)的安全可靠性(xing),并降低(di)運(yun)行(xing)成(cheng)本。
超(chao)臨界(jie)(jie)二(er)氧(yang)化(hua)(hua)碳(tan)流體萃取分(fen)離過程的(de)原(yuan)理是利(li)用(yong)(yong)(yong)超(chao)臨界(jie)(jie)二(er)氧(yang)化(hua)(hua)碳(tan)對某些特(te)殊(shu)天然產物(wu)具有特(te)殊(shu)溶(rong)(rong)解(jie)(jie)作用(yong)(yong)(yong),利(li)用(yong)(yong)(yong)超(chao)臨界(jie)(jie)二(er)氧(yang)化(hua)(hua)碳(tan)的(de)溶(rong)(rong)解(jie)(jie)能力(li)與其密(mi)度(du)的(de)關系,即利(li)用(yong)(yong)(yong)壓力(li)和溫度(du)對超(chao)臨界(jie)(jie)二(er)氧(yang)化(hua)(hua)碳(tan)溶(rong)(rong)解(jie)(jie)能力(li)的(de)影響而(er)進行的(de)。在超(chao)臨界(jie)(jie)狀(zhuang)態下(xia),將超(chao)臨界(jie)(jie)二(er)氧(yang)化(hua)(hua)碳(tan)與待分(fen)離的(de)物(wu)質(zhi)接觸,使(shi)其有選擇(ze)性地把極性大小、沸點高低和分(fen)子量大小的(de)成分(fen)依次萃取出來。
超(chao)臨界萃取設(she)備由(you)于(yu)全過(guo)程不用有機溶劑,因此萃(cui)取物絕(jue)無(wu)殘(can)留溶媒,同時也防止(zhi)了提取(qu)過程(cheng)對人體的毒害和對環(huan)境的污染,是100%的(de)純天(tian)然。萃取和分離合二(er)為(wei)一,當飽含(han)溶解物的(de)CO2-SCF流(liu)經分(fen)離器時(shi),由于壓力下降使得CO2與萃(cui)取物迅(xun)速成(cheng)為兩相(xiang)(氣液分(fen)離)而立即分(fen)開,不僅萃(cui)取效率(lv)高(gao)而且能耗較少,節約(yue)成(cheng)本。
