1. Kodi CMC ndi chiyani?
CMC, carboxymethylcellulose, ndi polima osungunuka m'madzi opangidwa kuchokera ku kusintha kwa mankhwala a cellulose achilengedwe. Monga chowonjezera pazakudya, KimaCell®CMC ili ndi kusungunuka kwamadzi bwino, kukhuthala komanso kukhazikika kwa colloidal, ndipo imagwiritsidwa ntchito kwambiri pamakampani azakudya. Imodzi mwa ntchito zake zazikulu popanga mkate ndikuwongolera kasungidwe ka madzi mu mkate, potero kumapangitsa kuti mkatewo ukhale wabwino komanso watsopano.
2. Kufunika kosunga chinyezi mu mkate
Kusungidwa kwa madzi kwa mkate ndi chinthu chofunikira kwambiri pozindikira kukoma kwake, kapangidwe kake komanso moyo wa alumali. Kusungidwa bwino kwa madzi kumathandizira:
Sungani kufewa: Pewani mkate kuti usakhale wolimba ndi wouma chifukwa cha kutayika kwa chinyezi.
Wonjezerani moyo wa alumali: chepetsani kuthamanga kwa ukalamba ndikuchedwetsa kuyambiranso kwa wowuma.
Imapangitsa kuti mkate ukhale wosasunthika komanso wosasunthika: Umapangitsa kuti mkate ukhale wofewa komanso wosavuta kusweka poucheka ndi kutafuna.
Komabe, pakupanga kwenikweni, chifukwa cha kutentha kwakukulu panthawi yophika, chinyezi mu mtanda chimakhala chosavuta kusungunuka, ndipo mutatha kuphika, mkate umakhalanso wotaya chinyezi chifukwa cha malo owuma. Panthawiyi, kuwonjezera CMC kungathandize kwambiri kusungirako madzi kwa mkate.
3. The enieni limagwirira zochita za CMC mu mkate
(1) Kumamwa bwino kwa madzi ndi kusunga madzi
Mamolekyu a CMC ali ndi magulu ambiri ogwira ntchito a carboxymethyl. Magulu a polar awa amatha kupanga zomangira za haidrojeni ndi mamolekyu amadzi, potero kumapangitsa kuti madzi azikhala ndi mphamvu zomangira komanso kusunga. Panthawi yopanga mkate, CMC imatha kuthandiza mtandawo kuyamwa madzi ambiri, kuonjezera chinyezi cha mtanda, komanso kuchepetsa kutuluka kwa madzi panthawi yophika. Ngakhale panthawi yosungira, CMC imatha kuchepetsa kutayika kwa madzi kwa mkate ndikusunga mawonekedwe ofewa.
(2) Sinthani kapangidwe ka mtanda ndi ductility
Monga thickener ndi colloidal stabilizer, CMC akhoza kusintha rheological katundu wa mtanda. Pamene kusakaniza mtanda, CMC akhoza kupanga mtanda zogwirizana dongosolo maukonde ndi wowuma ndi mapuloteni mu ufa, potero utithandize madzi atagwira mphamvu ya mtanda ndi kupanga mtanda zambiri zotanuka ndi ductile. Mbali imeneyi imathandizanso kukhazikika kwa thovu la mpweya panthawi yophika, potsirizira pake kupanga mkate wokhala ndi mawonekedwe ofanana ndi ma pores abwino.
(3) Kuchedwetsa ukalamba wowuma
Kukalamba wowuma (kapena retrogradation) ndi chifukwa chofunikira chomwe mkate umataya kufewa kwake. Akaphika, mamolekyu a wowuma mu mkate amakonzanso kupanga makhiristo, kupangitsa mkatewo kukhala wolimba. KimaCell®CMC imatha kuchedwetsa kukhazikika kwa mkate mwa kutsatsa pamwamba pa mamolekyu a wowuma ndikulepheretsa kukonzanso kwa unyolo wowuma.
(4) Synergy ndi zosakaniza zina
CMC imagwiritsidwa ntchito limodzi ndi zina zowonjezera chakudya (monga glycerin, emulsifiers, etc.) kupititsa patsogolo kusungirako madzi kwa mkate. Mwachitsanzo, CMC akhoza kugwira ntchito ndi emulsifiers pa kuwira dongosolo la mtanda kusintha bata wa thovu, potero kuchepetsa kutaya madzi pa kuphika. Kuphatikiza apo, mawonekedwe a unyolo wa polima a CMC amatha kugwira ntchito ndi ma humectants monga glycerin kuti asunge chinyezi cha mkate.
4. Momwe mungagwiritsire ntchito CMC ndi njira zopewera
Pakupanga mkate, CMC nthawi zambiri imawonjezeredwa ku ufa kapena kusungunuka. Mlingo weniweni nthawi zambiri umakhala 0.2% mpaka 0.5% yaubwino wa ufa, koma umayenera kusinthidwa molingana ndi chilinganizo ndi mtundu wazinthu. Mfundo zotsatirazi ziyenera kukumbukiridwa mukamagwiritsa ntchito:
Kusungunuka: CMC iyenera kusungunuka kwathunthu kupewa mapangidwe a particles kapena agglomerates mu mtanda, zomwe zimakhudza kugwirizana kwa mtanda.
Kuchuluka kowonjezera: Kugwiritsa ntchito kwambiri CMC kumatha kupangitsa kuti mkatewo ukhale wokhazikika kapena wonyowa kwambiri, chifukwa chake kuchuluka kwake kuyenera kuwongoleredwa moyenera.
Kuchuluka kwa maphikidwe: Kugwirizana kwa CMC ndi zosakaniza zina monga yisiti, shuga ndi emulsifiers zingakhudze kukwera kwa mkate ndi kapangidwe kake, chifukwa chake chophikacho chiyenera kukonzedwa mwa kuyesa.
5. Zotsatira za ntchito
Powonjezera CMC, kusunga madzi kwa mkate kumatha kusintha kwambiri. Zotsatirazi ndi zingapo zomwe zimachitika:
Kumverera konyowa kumawonjezeka pambuyo pophika: mkati mwa mkate ndi wonyowa pambuyo podulidwa, ndipo pamwamba siuma ndi kusweka.
Kukoma kokwanira: kufewa komanso zotanuka kwambiri mukamatafuna.
Nthawi yotalikirapo ya alumali: Mkate umakhala watsopano pakatha masiku angapo atausunga pa kutentha kwa firiji ndipo umauma msanga msanga.
6. Zochitika zachitukuko chamtsogolo
Pomwe kufunikira kwa ogula kwachilengedwe komanso thanzi lazakudya kumachulukirachulukira, njira zina za KimaCell®CMC zokhala ndi zowonjezera zochepa kapena magwero achilengedwe zimayamba kuyang'aniridwa pang'onopang'ono. Komabe, monga wokhwima, wokhazikika komanso wogwira ntchito posungira madzi, CMC ikadali ndi kuthekera kwakukulu kogwiritsa ntchito popanga mkate. Mtsogolomu,CMCkafukufuku wosintha (monga kukulitsa kukana kwa asidi kapena kuphatikiza ndi ma colloids ena achilengedwe) atha kukulitsanso magawo ake ogwiritsira ntchito.
Kupyolera mu mayamwidwe ake abwino kwambiri amadzi, kunyowa komanso kukhazikika kwa colloidal, CMC imapereka chithandizo chofunikira pakuwongolera kusungirako madzi kwa mkate ndikuwonjezera moyo wake wa alumali. Ndi chimodzi mwazowonjezera zofunika kwambiri pamakampani ophika amakono.
