Sodium Carboxymethyl cellulose, yotchedwa carboxymethyl cellulose (cmc) ndi mtundu wa polymer-polymer kusinthidwa kwa cellulose ya cellulose. Kapangidwe kake ka D-glucose unit mpaka Β (1 → 4) Glycosidic Corm yolumikizidwa ndi zigawo. Kugwiritsa ntchito CMC kuli ndi maubwino ambiri pazakudya zina.
01
CMC imagwiritsidwa ntchito kwambiri mu chakudya
(1) CMC ili ndi bata wabwino
M'malo ozizira monga popsicles ndi ayisikilimu, imatha kuwongolera mapangidwe a ayezi, onjezerani kukula ndikusunga ma yunifolomu, ndikusuta fodya, ndikukhala ndi mawonekedwe abwino komanso osalala.
Muzinthu zamkaka, kaya ndi mkaka woseketsa, mkaka wa zipatso kapena yogati, zitha kuchitira ndi protein mkati mwa mawonekedwe a emulsion (ph4.6) kupanga kukhazikika kwa emulsion ndikusintha kukana mapuloteni.
(2) CMC ikhoza kuphatikizidwa ndi okhazikika ena ndi ma emulsifiers
Mu chakudya ndi chakumwa, opanga mamiliyoni ambiri amagwiritsa ntchito zokhazikika, monga: monga: Xanthan chingamu, glyceror mafuta acid, ndi zina zowonjezera.
(3) CMC ili ndi pseudoplastity
Makutu a CMC amasinthasintha kosiyanasiyana. Kutentha kumakwera, mawonekedwe a yankho amachepa, komanso mosemphanitsa; Mphamvu ya chingwe itakhalapo, mafayilo a cmc adzachepa, ndipo ndikuwonjezera mphamvu ya misempha, chidwi chimachepa. Zinthu izi zimathandizira CMC kuti muchepetse zida ndikusintha bwino za homogenization pomwe mukusunthika, homogenizing, ndi mayendedwe akumapa, omwe samakhazikika ndi okhazikika.
02
Zofunikira
Monga kukhazikika kwa chikwangwani, masentimita kumakhudza momwe kumagwiritsidwira ntchito molakwika, ndipo ngakhale kuchititsa kuti katunduyo azikopedwa. Chifukwa chake, kwa masentimita, ndikofunikira kufalitsa bwino njira yothetsera kusintha kwake, kuchepetsa kuchuluka kwake, kusintha mtundu wazomera, kukonza bwino ntchito ndi kuchuluka kwake. Makamaka, chidwi chiyenera kulipidwa kwa njira iliyonse:
(1) Zosakaniza
1.
Zida zonse ndi luso losakaniza lomwe lingagwiritsidwe ntchito kuthandiza CMC kuti ibalalikire m'madzi. Kupitilira kumeta utali kwambiri, CMC imatha kunyowa m'madzi kuti ifulumire ma cmc.
Opanga ena pano amagwiritsa ntchito zosakanikirana ndi ufa kapena akasinja othamanga kwambiri.
2. Shuga Wowuma Kusakaniza Njira
Sakanizani bwino ndi CMC ndi shuga wokazinga pa chiwerengero cha 1: 5, ndikuwaza pang'onopang'ono pang'onopang'ono pang'onopang'ono kusunthira cmc.
3. Sungunulani mu madzi okwanira shuga
Monga caramel, etc., imatha kuthamangitsa kusungunuka kwa cmc.
(2) chowonjezera cha asidi
Kwa acid acidic, monga yogati, zinthu zosagwirizana ndi acid ziyenera kusankhidwa. Ngati atagwira ntchito bwino, mtunduwo umatha kukhala bwino komanso mpweya wabwino kapena stratication imalepheretsedwe.
1. Mukawonjezera acid, kutentha kwa ophatikizidwa kwa asidi kuyenera kulamuliridwa mosamalitsa, nthawi zambiri ≤20 ° C.
2. Asidi a asidi iyenera kuwongoleredwa mu 8-20%, kutsitsa.
3. Kuphatikiza kwa asidi kumatengera njira yopopera, ndipo imawonjezedwa motsogozedwa ndi chitoliro cha chotengera, nthawi zambiri mphindi 1-3.
4. Slurry Speed n = 1400-2400r / m
(3) Homogeneous
1. Cholinga cha emulsization
Homulo lotopetsa, wokhala ndi madzi odyetsa madzi, masentimita ayenera kuphatikizidwa ndi emulsifider, monga monoglyceride, kukakamizidwa kwa homogenization ndi 18-25mm, ndipo kutentha ndi 60-70 ° C.
2. Cholinga Chodziwika
Homogenization, ngati zosakaniza zingapo mu sitedide si yunifolomu kwathunthu, pamakhala zigawo zina zing'onozing'ono, zimayenera kukhala zovuta, kuthamanga kwa homogeniza, ndipo kutentha ndi 60-70 ° C.
(4)
CMC pamtunda wambiri, makamaka ngati kutentha kumakhala kwakukulu kuposa 50 ° C kwa nthawi yayitali, mafayilo owoneka bwino adzachepa mosatekeseka. Makulidwe a CMC of Center Opanga amatsika kwambiri mpaka 80 ° C kwa mphindi 30, kotero chosinthira kapena bala kapena bala likhoza kugwiritsidwa ntchito. Njira yosinthira kufupikitsa nthawi ya masentimita kutentha kwambiri.
(5) Kusamala kwina
1. Khalidwe losankhidwa liyenera kukhala loyera komanso lapamwamba lapamwamba momwe mungathere. Madzi abwino sayenera kugwiritsidwa ntchito popewa matenda azovuta komanso amakhudza mtundu.
2. Ziwiya zosungunuka ndikusunga CMC sizingagwiritsidwe ntchito pazithunzi zachitsulo, koma matumba osapanga dzimbiri, misempha yamatabwa, kapena mitsempha yamiyala itha kugwiritsidwa ntchito. Letsa kulowa kwa ma ionlenti ya zitsulo.
3. Pambuyo pakugwiritsa ntchito cmc, pakamwa pa thumba la pakompyuta liyenera kumangiriza zopweteka ndi kuteteza cmc.

Mayankho a Mafunso Pogwiritsa Ntchito CMC
Kodi mamasukidwe otsika mtengo bwanji, mafayilo-sing'anga, komanso mafano ambiri amasiyana? Kodi padzakhala kusiyana pa kusasinthika?
Yankho:
Zimamveka kuti kutalika kwa makelecular cheni ndi chosiyana, kapena kulemera kwa maselo ndi kosiyana, ndipo amagawika mafayilo ochepa. Zachidziwikire, magwiridwe antchito a macroscopic amafanana ndi mawonekedwe osiyanasiyana. Kukhazikika komweku kumakhala ndi mawonekedwe osiyanasiyana, kukhazikika kwazinthu komanso kuchuluka kwa asidi. Chiyanjano mwachindunji chimatengera yankho la malonda.
Kodi ndi ziti zomwe zimapangitsa kuti pakhale malo opezeka pamwamba pa 1.15? Mwanjira ina, kuchuluka kwa malo osokoneza bongo, kodi ntchito yakeyo idakulitsidwa?
Yankho:
Chogulitsacho chimakhala ndi gawo lalikulu la zolowa m'malo, kuchuluka kwa madzi, ndipo kuchepa kwa pseudoplastity. Zogulitsa zomwe zili ndi mafayilo omwewo ali ndi gawo lalikulu lazolowa m'malo mwake komanso kumverera kowonekeratu. Zogulitsa zomwe zili ndi gawo lalikulu la cholowa chili ndi chowonera chonyezimira, pomwe zinthu zokhala ndi malire olowa m'malo mwake zimakhala ndi yankho loyenerera.
Kodi ndi bwino kusankha ma vincy kuti apange zakumwa zotenthetsa?
Yankho:
Zogulitsa zapakatikati komanso zotsika kwambiri, kuchuluka kwa cholowa cha pafupifupi 0,90, ndi zinthu zomwe zimagwirizana ndi acid.
Kodi CMC ingasungunuke bwanji mwachangu? Nthawi zina, atawiritsa, imasungunuka pang'onopang'ono.
Yankho:
Sakanizani ndi ma colloids ena, kapena kufalikira ndi anitator 1000-1200 rpm.
Kuchepetsa kwa CMC sikwabwino, hydrophilicity ndiyabwino, ndipo ndizosavuta kusema, ndipo zinthu zomwe zili ndi digiri yapamwamba kwambiri ndizodziwikiratu! Madzi ofunda amasungunuka mwachangu kuposa madzi ozizira. Kuwiritsa nthawi zambiri sikulimbikitsidwa. Kuphika kwa nthawi yayitali kwa zinthu za CMC kudzawononga kapangidwe kake ndipo chinthucho chimataya ma viscy.
