Palm Oil Refining Khoom

 

Xibtes roj

Palm roj yog muab los ntawm xibtes pulp, thiab nws cov fatty acid muaj pes tsawg leeg yog saturated acids accounting rau 40 feem pua ​​mus rau 50 feem pua, ntawm uas 80 feem pua ​​yog palmitic acid, oleic acid yog lub ntsiab unsaturated acid, raws li linoleic acid, nplua nuj nyob rau hauv vitamin A thiab vitamin E, nrog ib tug sib sib zog nqus xim av. Vim lub decomposition ntawm xibtes txiv hmab txiv ntoo los ntawm lipolytic enzymes ua ntej sau thiab roj ntau lawm, ua ke nrog cov kev cuam tshuam ntawm kev ua thiab kev cia thiab kev thauj mus los, cov ntsiab lus ntawm dawb fatty acids nyob rau hauv cov roj txiv maj phaub roj yog siab heev, feem ntau nyob ib ncig ntawm 10 feem pua, thiab raws li siab li 30 feem pua. Kev siv cov roj xibtes tseem ceeb yog ua cov xab npum thiab muab ntau qib ntawm cov khoom noj tshwj xeeb roj.

Cov ntsiab lus ua haujlwm: Kev tshem tawm impurity thiab lim kub yuav tsum tsis txhob qis dua 50 degree, thiab cov ntsiab lus impurity ntawm cov roj lim yuav tsum tsis pub tshaj 0.2 feem pua. Thawj qhov kub ntawm qhov nruab nrab nruab nrab yog 30 ~ 35 degree, qhov kawg kub yog 60 ~ 65 degree, qhov concentration ntawm lye yog 16 ~ 18 degree Bé, cov nyiaj alkali ntau dhau rau {{23 }}.2 feem pua ​​~0.3 feem pua ​​ntawm cov roj, thiab lub sij hawm neutralization yog li ntawm 1 teev; qhov concentration ntawm lye yog tsis tu ncua neutralized 20 ~ 28 degree Bé, cov nyiaj alkali ntau dhau rau 10 feem pua ​​~ 25 feem pua ​​ntawm cov theoretical alkali, xab npum tshem tawm kub yog 70~ 95 degree, lub nruas tso dej yog 20 ~ 25L / h, thiab cov roj inlet siab yog 0.l ~ 0.3MPa, cov roj qhov hluav taws xob rov qab siab yog 0.1 ~ 0.15MPa, cov roj desoaping kub yog 85 ~ 90 degree, cov dej ntxuav ntxiv tso nyiaj rau 10 feem pua ​​~ 15 feem pua ​​​​ntawm cov roj ntim, thiab cov tshuaj ntxuav cov roj seem tsis ntau tshaj 50ppm. Lub decolorization kub ntawm cov roj thiab kua roj yog 105 ~ 110 degree, kev khiav hauj lwm siab yog 2.5 ~ 4.0kPa, lub sij hawm yog 15min, thiab tus nqi ntawm activated av nplaum ntxiv yog 3 feem pua ​​ntawm cov roj. Lub distillation deacidification thiab deodorization kub yog 240 ~ 250 degree, kev khiav hauj lwm siab yog 0.2 ~ 0.4kPa, thiab lub sij hawm yog 80 ~ 100min. Txias thiab crystallization kub Qhov kub ntawm qhov pib yog 70-80 degree, maj mam txias mus rau qhov kawg kub ntawm 20 degree nyob rau hauv li 24 teev, qhov kub ntawm qhov sib txawv ntawm cov dej txias thiab roj yog 5-8 degree , thiab lub siab pom yuav tsum tsis txhob siab thaum sib cais.

 

Palm Kernel Oil thiab Txiv maj phaub roj

Palm Kernel Oil thiab Txiv maj phaub roj yog cov roj tsis qhuav. Cov fatty acid muaj pes tsawg leeg yog dominated los ntawm lauric acid (sau rau 45 feem pua ​​~ 5l feem pua ​​ntawm cov fatty acid muaj pes tsawg leeg), ua raws li myristic acid (kwv yees li 13 feem pua ​​~ 25 feem pua), thiab cov ntsiab lus colloid yog tsawg, uas yog tshwj xeeb tshaj yog haum. rau lub cev refining deacidification. Palm kernel oil thiab txiv maj phaub roj muab faib ua qib xab npum thiab qib zaub mov. Cov txheej txheem refining ntawm refined edible roj yog raws li nram no.

Cov ntsiab lus tseem ceeb ntawm kev ua haujlwm: Lub hom phiaj tseem ceeb ntawm degumming qhuav yog tshem tawm impurities thiab kab hlau ions. Rau degumming, ntxiv phosphoric acid nrog ib tug concentration ntawm 85 feem pua ​​​​rau account rau 0.1 feem pua ​​~ 0.2 feem pua ​​ntawm cov roj. Tom qab stirring rau 15 feeb, ntxiv 2% ~ 3 feem pua ​​ntawm cov roj. Rau av nplaum decolorization thiab ntxiv adsorption degumming, kev khiav hauj lwm kub yog 105 ~ 110 degree, qhov kev khiav hauj lwm siab yog 2.5 ~ 4.{20}}kPa, lub lub sij hawm cov tshuaj tiv thaiv yog 10~15 min, qhov kub rau lim thiab cais av nplaum tsis siab tshaj 70 degree, thiab cov roj pretreatment yuav tsum tau P tsawg dua los yog sib npaug rau 5 ppm, Fe tsawg dua los yog sib npaug rau 0.1ppm, Cu tsawg dua lossis sib npaug rau 0.01ppm. Lub distillation deacidification thiab deodorization kub yog 240 ~ 250 degree, kev khiav hauj lwm siab siab yog 0.2 ~ 0.4kPa, lub stripping chav ntim account rau 1 feem pua ​​~ 4 feem pua ​​ntawm cov roj ntim, thiab lub sij hawm deacidification thiab deodorization yog 40 ~ 100 min.
