1. Cov khoom siv emulsification cov khoom siv neeg kho mob rau kev npaj emulsion yog feem ntau emulsifier, uas yog hom roj emulsification uas sib tov roj thiab dej tusyees. Tam sim no, muaj peb hom emulsifiers: emulsification tov, collooob thiab homogenizer. Hom, qauv thiab kev ua tau zoo ntawm emulsifier muaj kev sib raug zoo nrog qhov loj me (dispersibility nrog qhov loj me thiab qhov zoo (ruaj khov (ruaj khov) ntawm emulsion. Feem ntau, xws li lub emulsifier uas tseem muaj dav siv hauv cov tshuaj pleev ib ce, kev npaj emulsion muaj cov dispersibility. Cov lus yog loj thiab ntxhib, tsis tshua ruaj khov, thiab muaj ntau dua kev paug paug. Txawm li cas los xij, nws tsim khoom yog yooj yim thiab tus nqi yog pheej yig. Tsuav koj xaiv cov qauv tsim nyog ntawm lub tshuab thiab siv nws kom yog, nws tseem tuaj yeem tsim cov tshuaj pleev ib ce zoo nrog cov kev xav tau dav dav. Nyob rau hauv xyoo tas los, nqus khoom txheem homogenizer tau ua tiav kev vam meej, thiab emulsion npaj tau muaj kev sib xyaw ua ke tau zoo heev thiab kev ruaj khov.
2. Qhov kub ntawm qhov ntsuas kub tau muaj qhov cuam tshuam zoo ntawm kev ua tau zoo ntawm emulsification, tab sis tsis muaj qhov txwv tsis pub rau qhov kub. Yog tias roj thiab dej yog ob qho kua, emulsification tuaj yeem ua tiav los ntawm kev nplawm ntawm chav tsev kub. Feem ntau, cov emulsification kub yog nyob ntawm lub ntsiab lus melting ntawm lub siab zoo xws li hom tshuaj emulsifier thiab cov solubility ntawm cov roj theem thiab cov theem dej. Tsis tas li ntawd, qhov ntsuas kub ntawm ob theem yuav tsum tau khaws cia zoo li qub, thaum muaj txiaj ntsig kub, thaum muaj roj av, ua rau muaj lary los yog ntxhib, tsis sib xws emulsions. Feem ntau hais lus, thaum lub sij hawm sov, ntsuas kub ntawm cov roj thiab theem dej yuav tswj tau ntawm 75 ° C. Yog tias cov roj theem muaj cov khoom siv melting siab siv quav ciab thiab lwm yam, cov emulsification kub yuav siab dua nyob rau lub sijhawm no. Ib qho ntxiv, yog tias Viscosity nce zoo thaum lub sij hawm emulsification ua rau tuab thiab cuam tshuam lub stirring, lub emulsification kub tuaj yeem nce ntxiv. Yog tias emulsifier siv muaj qee theem inversion kub, lub emulsification kub kuj tseem nyiam xaiv nyob ib puag ncig ntawm theem inppersion. Lub emulsification kub kuj qee zaum muaj cov nyhuv ntawm cov particle loj ntawm emulsion. Piv txwv li, thaum lub roj av fatty acid anionic yog siv rau emulsification los ntawm lub xubfelification yog tswj hwm ntawm 80 ° me me ntawm emulsion yog li 1.8-2.0 μm. Yog tias emulsification tau ua ntawm 60 ° C, qhov loj me me yog li ntawm 6 μm. Thaum emulsified nrog cov emulsified, cov txiaj ntsig ntawm emulsification kub ntawm particle loj yog tsis muaj zog.
3. Emulsification lub sijhawm ntawmNqus Plua Plav HomogenizerTsim cov emulsification lub sijhawm muaj qhov cuam tshuam ntawm qhov zoo ntawm cov roj thiab cov khoom siv visculation yog ua kom lub kaw lus emulsification yog ua kom lub kaw lus emulsification yog ua kom lub kaw lus tag nrho, tab sis cov pulsification yog ua kom lub kaw lus emulsification yog ua kom lub kaw lus tag nrho emulsified, uas yog ze ze rau kev ua tau zoo ntawm cov Cov khoom siv emulsification. Lub sijhawm emulsification tuaj yeem txiav txim siab raws li kev paub thiab sim. Yog tias homogenizer (3000 RPM) yog siv rau emulsification, nws tsuas yog siv 3-10 feeb.
4. Stirring ceev emulsification muaj qhov muaj txiaj ntsig zoo ntawm emulsification, ib qho yog cov nyhuv ntawm stirring ceev ntawm emulsification. Lub stirring ceev yog ib nrab los ua kom cov roj theem thiab dej theem tag nrho cov tshuaj sib xyaw, thiab lub nrawm sib xyaw yog qhov siab heev
5. Stirring ceev ntawmNqus Plua Plav Homogenizer Kev tsim muaj ib qho kev cuam tshuam zoo ntawm emulsification, ib qho ntawm qhov uas yog tus cawv ntawm kev sib tsoo ntawm kev tawm tsam ntawm emulsification. Qhov ntsuas me ntsis yog ua kom cov roj theem thiab cov theem dej sib xyaw. Yog tias lub nrawm nrawm yog tsawg dhau, lub hom phiaj ntawm tag nrho tov yuav pom tseeb tsis tau ua tiav. Txawm li cas los xij, yog tias lub nrawm nrawm dhau lawm, huab cua npuas yuav raug coj mus rau hauv lub kaw lus, ua rau nws muaj peb-theem system. Ua emulsions tsis ruaj khov. Yog li no, kev nkag ntawm huab cua yuav tsum tau zam thaum lub sij hawm stirring, thiab lub tshuab nqus tsev emulsifier muaj kev ua tau zoo heev.
Ntse Zhitong muaj ntau xyoo ntawm kev paub hauv kev txhim kho, tsim cov nqus phaj tov khoom homogenizerNqus tsev homogenizer tov khoomthiab lub tshuab muaj peev xwm los ntawm 5l txog 18000l
