Palm Oil Refining Khoom

Palm Oil Refinery Decolorization Khoom

Yuav ua li cas kom tau ib tug ntshiab thiab pob tshab xibtes roj?

Cov txheej txheem ua noj ua haus cov roj ua kom zoo, feem ntau suav nrog degumming, deacidification, dissolution, decolorization, dewaxing, deodorization, decolorization txheej txheem yog qhov tseem ceeb ntawm cov roj refining, decolorization tsis yog tag nrho cov xim, tab sis los txhim kho cov xim roj, txhim kho cov roj zoo, mus rau hauv cov kauj ruam refining. los muab cov khoom tsim nyog cov khoom siv roj.

Palm roj yog nplua nuj nyob rau hauv carotene (0.05 feem pua ​​-0.2%) thiab yog txiv kab ntxwv tsaus. Cov xim no tsis tuaj yeem raug tshem tawm los ntawm alkalization, thiab tuaj yeem tshem tawm cov roj kom feem ntau lub teeb daj los ntawm oxidation. Palm roj kuj maj mam decolormented los ntawm tshav ntuj thiab huab cua.

Yog li ntawd, cov roj txiv maj phaub roj yog xim sib sib zog nqus, tsis pom tseeb, los ntawm kev ua decolorization, tom qab ua kom zoo kom ze rau qhov tsis muaj xim pob tshab, nyob rau hauv cov khoom muaj zog ze li ntawm cov xim dawb, tib lub sij hawm, decolorization tuaj yeem txo cov phospholipid cov ntsiab lus, peroxide tus nqi, xab npum ntsiab lus thiab hlau ion ntsiab lus, los txhim kho roj xim thiab tsw thiab txhim kho oxidation stability, rau cov roj ntxiv refined hydrogenation, deodorization muab ib tug zoo mob.

Tshiab decolor refining txheej txheem

Tam sim no, feem ntau txoj kev ntawm cov roj decolorization nyob rau hauv cov txheej txheem niaj hnub no yog cov av nplaum adsorption decolorization txoj kev, uas yog, siv cov av nplaum uas muaj zog xaiv adsorption nyhuv, nyob rau hauv tej yam kev mob kom tshem tawm cov xim yaj nyob rau hauv cov roj los yog cov xim dispersed los ntawm colloidal. particles thiab lwm yam impurities.

Vim yog cov txheej txheem kev noj qab haus huv ntawm cov roj refining, cov txheej txheem roj decolorization feem ntau yog teem rau hauv nruab nrab ntawm cov txheej txheem refining, vim hais tias cov txiv hmab txiv ntoo ntawm cov txiv hmab txiv ntoo muaj lipase ntau dua, nyuaj rau kev ua cov txheej txheem los yog tshem tawm tag nrho, nyob rau hauv cov txheej txheem ntawm xibtes. wool roj nyob rau hauv cov txheej txheem, lipase yooj yim hydrolysis thiab tsim kom muaj ntau cov fatty acids dawb, uas ua rau cov txheej txheem ntawm xibtes oleic acid tus nqi nce, cuam tshuam rau kev txhim kho cov khoom lag luam ntawm xibtes roj.

Yog li ntawd, txoj kev kho decolorization optimized ntawm xibtes roj tau tshwm sim tom qab, txoj kev yog desolvate cov khoom siv roj kom decolorized thiab ces qhuav, tom qab ziab, ntxiv decolorization tus neeg saib xyuas rau predecolorization kev kho mob, thiab siv av nplaum lim ncuav mog qab zib rau decolorization thiab siab pom;

Tom qab ntawd ua cov kev kho mob ua ntej deodorization, siv cov khoom ntim-hom deodorization ntauwd ua lub thawv, thiab ntxiv L-ascorbic acid permitate, flavonoids thiab phosphoic acid rau kev lim dej lim dej rau kev kho lub tshuab nqus tsev deodorization;

Tom qab kev kho lub tshuab nqus tsev deodorization, cov roj tau txias sai rau 3 ~ 5 C rau kev kho impurity. Tom qab lub impurity tshem tawm, cov roj yog tov nyob rau hauv lub premixed tank thiab sib tov tusyees thiab muab tso rau hauv lub decolorization ntauwd rau peb-theem refined kev kho mob, thiaj li mus tau lub xibtes roj.

Txhim kho cov decolorization zoo ntawm xibtes roj, thiab txo cov despidase khaws cia los ntawm xibtes roj hauv cov txheej txheem decolorization, thiab txo cov roj fatty acids dawb uas ua rau cov txheej txheem tom ntej.

Cov kauj ruam ua haujlwm tshwj xeeb:

S1Qhuav cov roj decolorized, xa mus rau lub tank decolorization tom qab ziab, ntxiv lub nplhaib-dextrin thiab aluminium magnesium silicate ua tus neeg saib xyuas decolorization, kub rau 60 ~ 65 "C, ua haujlwm rau 3 ~ 5min, thiab tom qab ntawd siv lub ntiaj teb dawb lim. ncuav mog qab zib rau decolorization thiab siab pom;

S2Kev kho mob ua ntej deodorization yog nqa tawm ntawm cov roj kho hauv qib S1. Hauv kev kho mob ua ntej deodorization, ib lub ntim deodorization ntauwd yog siv los ua lub thawv, thiab L-ascorbyl palmitate 1.2 ~ 1.8 feem pua ​​​​ntawm tag nrho qhov hnyav ntawm cov roj, flavonoids 0.{{10} }8 ~ 0.12 feem pua ​​​​ntawm tag nrho qhov hnyav ntawm cov roj thiab phosphoric acid 70 ~ 80 feem pua ​​​​ntawm tag nrho qhov hnyav ntawm cov roj ntxiv rau cov roj kho hauv qib S1. Qhov kub ntawm kev kho deodorization yog 210-230 degree thiab lub tshuab nqus tsev yog 0.07-0.08 MPa rau lub tshuab nqus tsev deodorization;

S3Cov roj uas tau kho nyob rau hauv kauj ruam S2 yog txias sai sai rau 3 ~ 5 degree rau decontamination, thiab cov roj decontaminated yog tov nrog dawb av nplaum nyob rau hauv lub pre-mixing tank, stirred thiab tov zoo - thiab muab tso rau hauv lub decolorization ntauwd rau zoo decolorization, thiabpeb theem ntawm nplua decolorizationNws yog siv rau decolorization zoo:

Ua ntej cua sov mus txog 80 ~ 90 C, ib txwm siab decolor 10 ~ 15min;

Tom qab ntawd muab tso rau hauv lub qhov cub oversaturated, thiab kub txog 105 ~ 110 C, decoloring kev kho mob rau 5 ~ 8min;

Thaum kawg, nqus cov decolization ntauwd rau lub nkoj siab ntawm {{0}}.05 ~ 0.06MPa thiab ua lub tshuab nqus tsev decolor rau 10 ~ 15min; xibtes roj tiav lawm.

Lus Cim:

1.Decolorized roj siv los ua raw khoom yog xibtes roj tau los ntawm txias txias thiab txias nias raws li raw khoom thiab ua tom qab degluming, deacidification thiab desoluization kho. 2.Nyob rau hauv kauj ruam S1, qhov loj piv ntawm cyclodextrin rau txhuas magnesium silicate nyob rau hauv cov decoloring tus neeg sawv cev yog 3: 5 mus rau 6: 7, thiab cov nyiaj ntxiv yog 4 mus rau 5 feem pua ​​ntawm cov loj ntawm cov roj yuav tsum decolorized.

3.Nyob rau hauv kauj ruam S1, thaum decolorization yog ua nyob rau hauv lub tank, stirring yog ua ntawm 60-70 r / min. 4.Nyob rau hauv kauj ruam S3, 10-30 μ m qhov txhab lim yog siv nyob rau hauv siab nyob rau hauv 0.13 ~ 0.15MPa.

5.Nyob rau hauv kauj ruam S3, cov tswj cov av nplaum thaum tov nyob rau hauv lub premixing tank yog 0.3 ~ 0.5 feem pua ​​ntawm tag nrho cov roj qhov hnyav.
