Covfat analyzergrinds cov khoom ua ntej extraction kom cov khoom-kua sib cuag cheeb tsam. Tom qab ntawd, muab cov khoom ntim rau hauv lub hnab lim ntawv thiab muab tso rau hauv lub extractor. Qhov qis kawg ntawm lub extractor yog txuas nrog lub khob hauv qab uas muaj cov kuab tshuaj leaching (anhydrous ether lossis roj av ether, thiab lwm yam), thiab cov reflux condenser txuas nrog nws.
Lub khob ntim hauv qab yog rhuab kom cov kuab tshuaj boil. Lub vapor nce los ntawm cov yeeb nkab txuas thiab nkag mus rau lub condenser. Tom qab condensed, nws drips rau hauv lub extractor. Cov kuab tshuaj tiv tauj cov khoom rau extraction. Thaum cov kuab tshuaj nyob rau hauv lub extractor mus txog lub siab tshaj plaws point ntawm lub siphon, cov kuab tshuaj uas muaj cov extract yog siphoned rov qab mus rau lub hwj, yog li rho tawm ib feem ntawm cov khoom. Tom qab ntawd cov leaching hnyav nyob rau hauv lub thoob-hauv qab khob txuas ntxiv evaporate, condense, leaching, thiab reflux, thiab rov ua cov txheej txheem no, yog li ntawd cov khoom tseem ceeb tau muab rho tawm tas li los ntawm cov kuab tshuaj ntshiab huv, thiab cov khoom rho tawm tau ntxiv rau hauv lub khob.
Cov kua-khoom extraction siv cov kuab tshuaj kom ua tiav lub hom phiaj ntawm kev rho tawm thiab kev sib cais los ntawm kev siv cov kuab tshuaj uas muaj cov solubility loj rau cov khoom uas yuav tsum tau muaj hauv cov khoom sib tov thiab me me solubility rau impurities.
Siphon: Inverted U-puab tubular qauv.
Siphon nyhuv: Siphon yog ib qho tshwm sim hydrodynamic uas siv qhov sib txawv ntawm cov kua qib los ua kom muaj zog, uas tuaj yeem nqus tau cov kua tsis muaj kev pab ntawm lub twj tso kua mis. Tom qab cov kua ntawm qhov chaw siab dua sau cov siphon, cov kua hauv lub thawv yuav txuas ntxiv ntws mus rau qhov chaw qis dua los ntawm siphon. Nyob rau hauv cov qauv no, cov kua siab sib txawv ntawm ob qhov kawg ntawm cov yeeb nkab tuaj yeem thawb cov kua hauv qhov siab tshaj plaws thiab tawm mus rau lwm qhov kawg.
Roj Crude: Tom qab cov qauv muab rho tawm nrog anhydrous ether los yog roj av ether thiab lwm cov kuab tshuaj, cov khoom uas tau los ntawm steaming tawm cov kuab tshuaj yog hu ua rog los yog crude rog nyob rau hauv cov zaub mov tsom xam. Vim tias ntxiv rau cov rog, nws kuj muaj cov xim thiab cov roj tsis hloov pauv, waxes, resins thiab lwm yam khoom.
