Pob kws noob roj Refining tiav cov cuab yeej

Crude pob kws roj yog ib tug tob liab amber zaub roj tau los ntawm nias los yog leaching pob kws kab mob. Crude pob kws roj muaj phospholipids, sterols, tocopherols thiab lwm yam unsaponifiables, fatty acids, waxes, thiab ib tug tshwj xeeb tsw. Cov roj pob kws roj muaj cov ntsiab lus siab impurity thiab ua turbid ntawm qis kub thiab tsis tuaj yeem siv ncaj qha. Tom qab refining, nws muaj peev xwm tau txais pob kws refined roj uas tsis muaj huab point, tsawg melting point thiab ruaj khov cia, uas ua tau raws li lub teb chaws tus qauv.

Raws li muaj pes tsawg leeg thiab cov khoom ntawm impurities hauv pob kws roj, nws tuaj yeem muab faib ua peb pawg:

(1) Insoluble khoom impurities, xws li sludge, ncuav mog qab zib hmoov, fiber ntau, av nplaum, catalyst, thiab lwm yam.

(2) Colloidal impurities, xws li dawb fatty acids, sterols, vitamin E, pigments, vitamins, gossypol, thiab lwm yam.

(3) Volatile impurities, xws li dej, cawv, hydrocarbon solvents, tsw ntxhiab, thiab lwm yam.

Feem ntau impurities muaj teeb meem rau qhov zoo thiab kev ruaj ntseg ntawm pob kws roj. Piv txwv li, noo noo yuav tsis tsuas cuam tshuam rau lub pob tshab ntawm cov roj, tab sis kuj txhawb lub hydrolysis thiab rancidity ntawm roj; Dawb fatty acids cuam tshuam qhov tsw thiab txhawb kev deterioration; Phospholipids tuaj yeem huab cov roj thiab tsim cov dej nag dub thaum cua sov. Ntau yam pigments ncaj qha cuam tshuam cov xim ntawm cov roj thiab txhawb cov rancidity ntawm cov roj.

Main txheej txheem ntws ntawm pob kws roj refining khoom：

(1) Degumming ntawm pob kws roj: txoj kev hydration thiab acid refining feem ntau yog siv los tshem tawm phospholipids, mucus, resin, protein, suab thaj thiab kab hlau los ntawm cov roj crude.

(2) Deacidification ntawm pob kws roj: dawb fatty acids, acid pigments, sulfides, insoluble impurities thiab kab hlau nyob rau hauv cov roj raug tshem tawm los ntawm cov zaub mov qib alkali neutralization txoj kev.

(3) Pob kws roj-dej ntxuav: ntxuav cov xab npum hneev thiab dej-soluble impurities nyob rau hauv cov roj thaum lub sij hawm deacidification.

(4) Lub cev qhuav dej ntawm pob kws roj: cov dej hauv cov roj refined raug tshem tawm los ntawm cua sov thiab nqus kom qhuav.

(5) Decolorization ntawm pob kws roj: siv adsorbents xws li av nplaum, aluminium silicate thiab activated carbon kom tshem tawm ntau yam pigments, colloids thiab oxides hauv cov roj.

(6) Deodorization ntawm pob kws roj: lub hauv paus ntsiab lus ntawm lub tshuab nqus tsev stripping yog siv los tshem tawm cov tshuaj tsw qab molecular, dawb fatty acids, glycerol monoesters, glycolipids, sulfides, thermal decomposition khoom ntawm pigments, thiab lwm yam.

(7) Dewaxing los yog degreasing ntawm pob kws roj: khov, crystallization los yog winterization crystallization yog tsuas yog siv los tshem tawm wax roj nyob rau hauv cov roj los ntawm fractionation.
