Dab tsi impurities raug tshem tawm los ntawm cov khoom siv roj refining?
Cov roj uas tsuas yog crushed los ntawm cov khoom siv squeezing yog hu ua roj crude lossis roj crude. Nws muaj ntau yam impurities thiab yuav tsum tau kho nrog cov cuab yeej refining kom tshem tawm cov impurities sab hauv. Dab tsi impurities tuaj yeem tshem tawm cov khoom siv roj refinery? Cia peb txheeb xyuas kom meej.
Feem ntau ntawm cov muaj pes tsawg leeg ntawm cov roj ntxhib yog sib xyaw fatty acid triglyceride, uas yog cov roj nruab nrab, uas peb hu ua cov roj ntshiab. Tsis tas li ntawd, muaj ntau yam uas tsis yog-glycerin, uas yog qhov peb hu ua impurities. Lub protagonist peb xav tham txog ntawm no yog cov impurities. Cia peb saib seb dab tsi yog impurities:

1. Khoom impurities. Nws muaj sediment, embryo, ncuav mog qab zib residue, fiber, ntoo chips, plua plav thiab lwm yam khoom impurities. Hom impurities no insoluble hauv roj thiab impurities hauv cov roj.
2. Dej impurities. Dej kuj yog ib qho impurities hauv cov roj, muaj ob qhov chaw. Ib qho yog cov dej seem hauv cov roj thaum lub sij hawm roj, thiab lwm qhov yog cov dej nquag ntxiv thaum lub sij hawm hydration thiab lub cev qhuav dej. Cov cuab yeej ua kom zoo tuaj yeem tshem tawm cov dej hauv cov roj thiab roj. Cov dej noo no yuav hloov cov xim ntawm cov rog, tsim tsw, thiab ua kom cov kua qaub tsis ua haujlwm.
3. Collagen impurities. Xws li impurities feem ntau yog phospholipids, protein, qab zib, cob, thiab mucus. Lawv tau yooj yim cuam tshuam los ntawm dej kub thiab electrolytes thiab hloov lub xeev hauv cov roj. Cov cuab yeej ua kom zoo no tshem tawm cov dej tsis huv los ntawm kev ua dej, lub cev qhuav dej thiab lwm txoj hauv kev.

4. Lipid-soluble impurities. Cov khoom tseem ceeb ntawm hom impurities no yog dawb fatty acids, pigments, alcohols, macarol, hydrocarbons, wax, ketones, kab hlau thiab organic phosphorus, mercury, polygon gallery, pwm, thiab lwm yam gallel toxin tshwm sim los ntawm ib puag ncig muaj kuab paug. Cov impurities no tuaj yeem raug tshem tawm los ntawm alkaline melting thiab siv cov cuab yeej ua kom zoo.
5. Kuaj impurities. Hlau, tshuaj tua kab, polychic aromatics, daj cytoids, thiab lwm yam, yuav raug tshem tawm nyob rau hauv tag nrho cov kev sib txuas thaum lub sij hawm refining txheej txheem ntawm no hom impurities. Piv txwv li, alkaline refined txuas tuaj yeem tshem tawm daj glimotoxin, thiab hlau impurities tuaj yeem raug tshem tawm.
