CMC Thov cov yam ntxwv thiab cov txheej txheem yuav tsum muaj nyob hauv cov khoom noj

Kev siv CMC muaj ntau yam zoo dua lwm cov zaub mov thickeners:

1. CMC tau siv dav hauv cov zaub mov thiab nws cov yam ntxwv

(1) CMC muaj kev ruaj khov zoo

Hauv cov khoom noj txias xws li popsicles thiab mis nyuj khov, kev tsim kho cov qauv dej khov, tiv thaiv melting, muaj qhov zoo thiab du thiab whiten xim. Hauv cov khoom noj mis nyuj, txawm hais tias nws qab kua txiv hmab txiv ntoo lossis kua mis muaj txiaj ntsig, nws tuaj yeem ua rau muaj protein ntawm lub ntsej muag nrog lub emulsion thiab txhim kho cov protein.

(2) cmc tuaj yeem sib txuas nrog lwm cov stabilizers thiab emulsifiers.

Hauv cov khoom noj thiab dej haus cov khoom lag luam, cov tuam ntxhab dav dav siv ntau yam ntawm cov hluav taws xob, thiab emulshan, sucrose fatty acid ester, etc. rau compounding. Cov txiaj ntsig zoo tuaj yeem ua tiav, thiab cov teebmeem kev sib txuam tuaj yeem ua tiav los txo cov nqi ntau lawm.

(3) cmc yog pseudopastic

Lub viscosity ntawm cmc yog thim rov qab ntawm ntau qhov kub. Raws li qhov kub nce, lub viscosity ntawm kev daws teeb meem tsawg, thiab hloov ua lwm yam; Thaum lub zog shear tshwm sim, viscosity ntawm cmc txo, thiab raws li shear zog nce, lub viscosity ua me. Cov khoom no pab CMC kom txo cov khoom siv thauj khoom thiab txhim kho homogenization ua tau zoo thaum ua kom cov khoom thauj khoom, thiab xa hluav taws xob, uas yog unmatched los ntawm lwm cov stabilizers.

2. Cov txheej txheem yuav tsum tau ua

Raws li qhov tsis muaj peev xwm siv tau zoo, cmc yuav cuam tshuam nws cov nyhuv yog tias siv tsis raug, thiab txawm ua rau cov khoom yuav tsum tau txhuam. Yog li ntawd, rau CMC, nws yog qhov tseem ceeb heev rau tag nrho cov kev daws txhawm rau txhim kho nws txoj kev ua tau zoo, txo cov khoom lag luam zoo thiab nce tawm los. Qhov no yuav tsum muaj txhua peb cov khoom noj khoom haus kom nkag siab cov yam ntxwv ntawm ntau cov txheej txheem ua si, tshwj xeeb yog nyob rau hauv txhua theem theem yuav tsum xyuam xim rau:

(1) Cov khoom xyaw

1. Siv cov neeg siv tshuab ceev sheat dispersion txheej txheem: Txhua yam khoom siv nrog kev sib xyaw muaj peev xwm tuaj yeem siv los pab CMC kom tawg hauv dej. Los ntawm kev kub ceev shear, cmc tuaj yeem soaked nyob rau hauv dej tusyees kom ceev rau kev sib cais ntawm cmc. Qee cov tuam ntxhab tam sim no siv cov dej sib xyaw ua ke lossis cov hlau hluav taws kub ceev.

2. Qab Zib Qhuav-Sib tov Kev sib xyaw: Sib tov CMC thiab qab zib ntawm qhov sib piv ntawm 1: 5, thiab maj mam nphoo rau hauv tas mus li Daws rau CMC.

3. Dissolving nrog dej qab zib cheese, xws li Caramel, tuaj yeem nrawm qhov sib cais ntawm CMC.

(2) acid ntxiv

Rau qee qhov dej acidic, xws li muaj kua nyeem qaub, acid-resistant cov khoom yuav tsum tau xaiv. Yog tias lawv tau ua haujlwm ib txwm, cov khoom lag luam zoo tuaj yeem txhim kho thiab cov khoom siv nag lossis daus thiab stratification tuaj yeem tiv thaiv tau.

1. Thaum ntxiv cov kua qaub, qhov ntsuas kub ntawm cov kua qaub ntxiv yuav tsum tau nruj me ntsis kev tswj hwm, feem ntau tsawg dua 20 ° C.

2. Tus kua qaub yuav tsum tau tswj hwm ntawm 8-20%, qhov qis dua qhov zoo dua.

3. Cov kua tshuaj txau cov txheej txheem, thiab nws yog ntxiv raws txoj kev coj ua ntawm lub thawv sib txawv, feem ntau 1-3min.

4. Slurry ceev n = 1400-2400r / m

(3) homogeneous

1. Lub hom phiaj ntawm emulsification.

Homogenization: Rau roj-muaj pub kua noj, cmc yuav tsum tau compounded nrog emulsifiers, xws li ib homogenizeride siab ntawm 18-25Mpa thiab kub ntawm 60-70 ° C.

2. Decentralized lub hom phiaj.

Homogenization. Yog hais tias muaj ntau yam xyaw nyob rau hauv thaum ntxov theem tsis yog hnav kiag li, thiab tseem muaj qee qhov me me, lawv yuav tsum yog homogenized. Cov Homogenization Siab yog 10Mpa thiab qhov kub yog 60-70 ° C.

(4) kom tsis muaj menyuam

Thaum CMC tau nthuav tawm qhov kub thiab txias, tshwj xeeb tshaj yog thaum qhov ntsuas kub siab dua 50 ° C rau lub sijhawm ntev, lub viscosity ntawm kev ua tsis zoo yuav txo qis itreversibly. Lub viscosity ntawm CMC los ntawm cov chaw tsim khoom dav dav yuav poob siab heev ntawm qhov kub ntawm 80 ° C rau 30 feeb. Kev tsis muaj menyuam txoj kev kom luv luv lub sijhawm ntawm CMC ntawm qhov kub.

(5) Lwm yam kev ceev faj

1. Cov dej uas raug xaiv yuav tsum tau huv thiab kho cov kais dej kom ntau li ntau tau. Dej zoo yuav tsum tsis txhob siv kom tsis txhob muaj mob microbial thiab cuam tshuam cov khoom lag luam zoo.

2. Cov tais diav rau cov yaj thiab khaws cia cmc tsis tuaj yeem siv hauv cov thawv hlau, tab sis cov thawv ntoo steel, lossis cov ntim ntoo tuaj yeem siv. Tiv thaiv qhov infiltration ntawm cov hlau sib dhos ions.

3. Tom qab txhua qhov siv CMC, lub qhov ncauj ntawm lub hnab ntim khoom yuav tsum tau khi kom nruj kom tiv thaiv kev nqus dej noo thiab tsis zoo ntawm CMC.
