Kev tshuaj xyuas kev lag luam luv luv thiab kev cia siab yav tom ntej

Kev ua kom luv yog ib hom roj khov siv rau hauv kev ua zaub mov uas cov khoom tseem ceeb yog roj zaub lossis roj tsiaj. Kev ua kom luv yog siv dav hauv kev ci, kib thiab lwm yam kev ua zaub mov, lub hom phiaj tseem ceeb yog ua kom cov zaub mov tawv thiab saj zoo dua. Nrog rau kev txhim kho ntawm kev lag luam zaub mov thoob ntiaj teb, kev lag luam ua kom luv kuj tseem loj hlob thiab qhia txog kev sib txawv ntawm kev sib txawv thiab qib siab.

Kev Txheeb Xyuas Txog Kev Lag Luam Luv Nqi Thoob Ntiaj Teb

Lub lag luam thoob ntiaj teb ua kom luv luv tau qhia txog kev loj hlob ruaj khov hauv xyoo tas los no, thiab qhov loj ntawm kev lag luam tau nthuav dav txhua xyoo. Raws li daim ntawv tshawb fawb kev lag luam, cov tsav tsheb tseem ceeb ntawm kev lag luam thoob ntiaj teb ua kom luv luv yog qhov kev thov khoom noj ci ntau ntxiv, kev txhim kho sai ntawm kev lag luam ua zaub mov, thiab cov neeg siv khoom nrhiav cov zaub mov zoo. Tshwj xeeb tshaj yog nyob rau hauv cov lag luam tshiab, xws li thaj av Asia-Pacific, Latin America thiab lwm qhov chaw, nrog rau kev txhim kho ntawm kev lag luam thiab kev txhim kho ntawm cov qauv kev ua neej, kev noj cov khoom ci thiab cov zaub mov ceev tau nce ntxiv ntau, txhawb nqa kev nthuav dav ntawm kev lag luam ua kom luv luv.

Cov qauv kev lag luam thiab cov teeb meem

1. Kev Noj Qab Haus Huv thiab Kev Noj Haus: Vim muaj kev nyiam noj zaub mov zoo, cov neeg siv khoom thiaj li ceev faj txog cov roj ua kom luv uas muaj cov roj trans fatty acids thiab cov roj saturated. Vim li no, kev lag luam tseem niaj hnub tsim thiab txhawb cov khoom ua kom luv uas muaj cov roj trans fatty acid tsawg, cov roj saturated tsawg, xws li kev siv roj xibtes, roj paj noob hlis, roj taum pauv thiab lwm yam khoom siv raw los hloov cov roj tsiaj ib txwm muaj.

2. Kev tiv thaiv ib puag ncig thiab kev ruaj khov: Ntau tus neeg tsim khoom luv luv tau pib tsom mus rau kev tiv thaiv ib puag ncig thiab kev ruaj khov, los ntawm kev ua kom zoo dua cov txheej txheem tsim khoom, txo cov pa roj carbon thiab siv cov khoom siv hluav taws xob rov ua dua tshiab los ua kom tiav cov khoom ntsuab. Piv txwv li, kev tswj hwm kev ruaj khov ntawm cov khoom siv roj xibtes tau dhau los ua qhov tseem ceeb hauv kev lag luam.

3. Kev tsim kho tshiab ntawm thev naus laus zis: Cov thev naus laus zis ua tiav siab heev tau siv dav hauv kev ua kom luv luv ntawm kev tsim khoom, xws li kev hloov kho enzymatic, kev rho tawm kua supercritical, kev distillation molecular thiab lwm yam thev naus laus zis, txhim kho cov khoom zoo thiab kev ua haujlwm zoo.

Cov khoom siv ua kom luv dua

Kev tsim cov khoom luv luv muaj ntau yam kev sib txuas ua ke nyuaj thiab xav tau cov khoom siv siab dua. Cov khoom siv tseem ceeb suav nrog:

1. Cov khoom siv roj refining: suav nrog degumming, deacidification, decolorization, deodorization thiab lwm yam txheej txheem ntawm cov khoom siv, siv los tshem tawm cov khoom tsis huv thiab cov ntxhiab tsw phem hauv cov roj nyoos, txhim kho qhov zoo ntawm cov roj.

2. Cov khoom siv Hydrogenation: Cov roj zaub ua kua hloov pauv mus ua cov rog khov lossis ib nrab khov los ntawm cov txheej txheem catalytic hydrogenation los txhim kho kev ruaj khov thiab kev ua haujlwm ntev ntawm cov roj.

3. Cov khoom siv Crystallization thiab txias: siv los tswj cov txheej txheem crystallization ntawm cov roj los tsim cov qauv siv lead ua zoo tagnrho los txhim kho cov khoom siv lub cev thiab kev ruaj khov ntawm kev ua kom luv luv (scraped surface heat exchanger, SSHE).

4. Cov khoom siv sib tov thiab sib xyaw: sib tov ntau hom roj thiab cov rog, thiab sib xyaw cov khoom kom ntseeg tau tias muaj kev ruaj khov ntawm qhov zoo (lub tshuab pin rotor).

5. Cov khoom siv ntim khoom: siv rau kev ntim cov khoom luv luv tiav lawm, cov ntawv feem ntau suav nrog cov thawv ntawv, cov kaus poom hlau, cov thoob yas, thiab lwm yam, kom tau raws li qhov xav tau ntawm cov neeg siv khoom sib txawv.

Kev cia siab yav tom ntej

Yav tom ntej, nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev hloov pauv ntawm kev thov ntawm cov neeg siv khoom, kev lag luam ua kom luv luv yuav txuas ntxiv mus rau kev txhim kho hauv kev noj qab haus huv, kev tiv thaiv ib puag ncig thiab kev txawj ntse. Kev tsim cov khoom siv raw tshiab, kev siv cov txheej txheem tsim khoom ntsuab thiab kev nrov ntawm cov thev naus laus zis tsim khoom ntse yuav coj ntau lub sijhawm thiab kev cov nyom rau kev lag luam ua kom luv luv. Cov tuam txhab yuav tsum ua raws li cov qauv kev ua lag luam thiab tsis tu ncua tsim kho kom tau raws li kev thov thoob ntiaj teb rau cov khoom ua kom luv luv zoo. Ua kom luv luv yog ib hom roj khov siv hauv kev ua zaub mov uas cov khoom tseem ceeb yog roj zaub lossis roj tsiaj. Ua kom luv luv yog siv dav hauv kev ci, kib thiab lwm yam kev ua zaub mov, lub hom phiaj tseem ceeb yog ua kom cov zaub mov crispy thiab saj. Nrog rau kev txhim kho ntawm kev lag luam zaub mov thoob ntiaj teb, kev lag luam ua kom luv luv kuj tseem loj hlob thiab qhia txog kev sib txawv thiab qib siab.
