"Decolorizing and Deodorizing Master" mu Makampani a ShugaⅠ
M'munda wamakampani azakudya ndi zakumwa, makampani a shuga ndi amodzi mwamagawo ofunikira omwe amagwiritsidwa ntchito ndi kaboni. Pakupanga mitundu ya shuga monga shuga wa nzimbe, shuga wa beet, shuga wowuma, maltose, lactose, molasses, xylose, xylitol, shuga, ndi hydrolyzed protein solution, activated carbon imakhala ndi gawo lofunikira pakuchepetsa komanso kununkhira.
Mafakitole a shuga amagawidwa kukhala mafakitale a nzimbe ndi mafakitale a shuga wa beet. Njira yothetsera shuga imakhala ndi mitundu yosiyanasiyana yamitundu monga melanoidins, caramel, ndi iron-polyphenol complexes. Mpweya wopangidwa ndi activated, womwe uli ndi malo akuluakulu (500 - 1500m²/g) komanso mawonekedwe olemera a mesopores ndi ma micropores, amatha kuwonetsa ntchito yabwino yotsatsa komanso kuchita bwino kwambiri pothana ndi mayankho a shuga.
Pali ma micropores ambiri mkati mwa tinthu tating'onoting'ono ta kaboni, ndipo kukula kwa pore ndikokulirapo, kuyambira ma angstroms angapo mpaka ma micrometer angapo. Makamaka, pali ma micropores ambiri okhala ndi kukula kwa pore mumitundu ingapo mpaka makumi angapo angstroms. Chilichonse mwa ma microporeswa chimafanana ndi malo enaake, zomwe zimapangitsa kuti kaboni yonseyo ikhale yodabwitsa kwambiri. Pa 1 gramu ya carbon activated yokhala ndi ntchito zabwino kwambiri, malo ake enieni amatha kufika pafupifupi 1000m². Chifukwa mphamvu ya atomiki yomwe ili pamwamba pa mpweya woyendetsedwa ndi mpweya imakhala yopanda mphamvu ndipo pali mphamvu zotsalira za valence, kutengera malo akuluakulu oterowo, mphamvu zake zapamtunda ndizofunika kwambiri. Ndi chifukwa cha zotsatira za adsorption kuti gawo la mphamvu zopanda unsaturated pamtunda wa carbon activated likhoza kulipidwa pamlingo wina, motero kuchepetsa mphamvu ya pamwamba. Choncho, pansi pa kutentha ndi kupanikizika kwapadera, pamwamba pa carbon activated imangodzipangira zinthu zomwe zingachepetse mphamvu zake. Komabe, carbon activated imatulutsa zinthu zosiyanasiyana kuchokera ku yankho, kuchuluka kwa adsorption sikumagwirizana ndi kuchuluka kwa zinthu izi mu yankho. Activated carbon nthawi zonse imapangitsa kuti solute concentration pa adsorption ikhale yabwino. Mwanjira iyi, ngakhale mphamvu ya adsorption ikakhala yofanana, zinthu zomwe sizili ndi shuga zomwe zili ndi ndende yotsika mumtsuko wa shuga zimatha kutsatiridwa ndi kaboni wolumikizidwa poyerekeza ndi sucrose wokhala ndi ndende yayikulu. Zinthu zamitundumitundu zomwe zili mumadzimadzi nthawi zambiri zimakhala ndi ma molekyulu akulu kwambiri komanso zolemera kwambiri. Kupyolera mu ma adsorption a activated carbon, mphamvu yake ya pamwamba imachepetsedwa kwambiri, ndipo madzi omwe amathiridwa ndi carbon activated amatha kuwononga kwambiri. Ndi chifukwa chakuti carbon activated ili ndi mphamvu yabwino kwambiri yochotsera mtundu ndi kuyeretsa madzi kuti ikhale yogwiritsidwa ntchito mofala komanso mogwira mtima m'mafakitale apamwamba a shuga kunja.
Pamene activated carbon imagwiritsidwa ntchito pochiza njira ya shuga, kuwonjezera pa zotsatira zake zazikulu za decolorization, imathanso kuchotsa colloids ndi pamwamba - zonyansa zogwira ntchito mu shuga. Izi zidzawonjezera kugwedezeka kwa shuga, kuchepetsa kukhuthala kwake, kuchepetsa kutulutsa chithovu panthawi ya evaporation, kuonjezera liwiro la crystallization, ndipo kungathe kupititsa patsogolo ndondomeko ya crystallization ya shuga, kulimbikitsa kulekana kwa molasses ku makhiristo a shuga.
