"Decolorizing and Deodorizing Master" na Ụlọ Ọrụ SugarⅠ
N'ọhịa nke ụlọ ọrụ nri na ihe ọṅụṅụ, ụlọ ọrụ shuga bụ otu n'ime mpaghara ngwa dị mkpa nke carbon na-arụ ọrụ. N'oge usoro mmepụta nke ụdị shuga dị ka shuga okpete, sugar beet, sugar starch, maltose, lactose, molasses, xylose, xylitol, glucose, na ngwọta protein hydrolyzed, carbon na-arụ ọrụ na-arụ ọrụ dị mkpa n'ime agba na deodorization.
A na-ekewa ụlọ ọrụ ndị na-emepụta shuga gaa na ụlọ ọrụ okpete na ụlọ ọrụ sugar beet. Ngwọta shuga nwere ihe dị iche iche na-agba agba dị ka melanoidins, caramel, na ígwè-polyphenol complexes. Carbon arụ ọrụ, nke nwere nnukwu mbara elu (500 - 1500m² / g) yana usoro mesopores na micropores bara ụba, nwere ike igosipụta arụmọrụ mgbasa ozi dị mma yana arụmọrụ decolorization dị elu mgbe ị na-emeso ụdị shuga shuga.
Enwere ọtụtụ micropores n'ime ụmụ irighiri carbon a na-arụ ọrụ, na oke oghere dị obosara nke ukwuu, site na angstroms ole na ole ruo ọtụtụ micrometers. Karịsịa, e nwere ọnụ ọgụgụ buru ibu nke micropores na pore nha na nso nke ole na ole ruo ọtụtụ iri iri nke angstroms. Nke ọ bụla n'ime micropores ndị a kwekọrọ n'otu akụkụ elu, na-eme ka akụkụ elu nke carbon arụ ọrụ n'ozuzu ya dị ịrịba ama. Maka gram 1 nke carbon na-arụ ọrụ nke ọma, mpaghara elu ya nwere ike iru ihe dịka 1000m². N'ihi na atomiki ike ubi n'elu nke carbon na-arụ ọrụ bụ na unsaturated ala na e nwere residual valence agha, dabere na otú a nnukwu kpọmkwem n'elu ebe, ya elu ike dị oke mkpa. Ọ bụ kpọmkwem n'ihi mmetụta mgbasa ozi na enwere ike ịkwụ ụgwọ ike na-adịghị mma n'elu carbon na-arụ ọrụ ruo n'ókè ụfọdụ, si otú a na-ebelata ike elu. Ya mere, n'okpuru ọnọdụ okpomọkụ kpọmkwem na nrụgide, elu nke carbon na-arụ ọrụ ga-eme ka ihe ndị nwere ike belata ike elu ya na-akpaghị aka. Otú ọ dị, mgbe carbon na-arụ ọrụ na-eme ka ihe dị iche iche dị iche iche na-esi na ngwọta, ọnụ ọgụgụ nke adsorption adịghị adaba na oke nke ihe ndị a na ngwọta. Carbon na-arụ ọrụ mgbe niile na-eme ka itinye uche solute dị n'elu mgbasa ozi guzozie eguzozi. N'ụzọ dị otú a, ọbụlagodi mgbe ikike mgbasa ozi bụ otu ihe ahụ, ihe ndị na-abụghị shuga na-enwe mmetụta dị ala na ngwọta shuga nwere ike ịgbasa ya site na carbon na-arụ ọrụ ma e jiri ya tụnyere sucrose nwere nnukwu uche. Ihe ndị na-acha uhie uhie dị na sirop na-enwekarị nnukwu ụda molekụla na nnukwu ibu molekụla. Site na mgbasa ozi nke carbon na-arụ ọrụ, a na-ebelata ike elu ya ruo n'ókè dị ukwuu, na sirop a na-emeso ya na carbon na-arụ ọrụ nwere ike nweta ọkwa dị ịrịba ama nke decolorization. Ọ bụ kpọmkwem n'ihi na carbon na-arụ ọrụ nwere ezigbo decolorization na ike dị ọcha maka sirop ka etinyere ya n'ọtụtụ ebe na nke ọma na ụlọ ọrụ shuga dị elu na mba ọzọ.
Mgbe a na-eji carbon arụ ọrụ na-agwọ ngwọta shuga, na mgbakwunye na mmetụta decolorization ya dị ịrịba ama, ọ nwekwara ike wepụ colloid na elu - adịghị arụ ọrụ na ngwọta shuga. Usoro a ga-eme ka esemokwu dị n'elu nke ngwọta shuga dịkwuo elu, belata viscosity ya, belata ọgbọ ụfụfụ n'oge usoro evaporation, na-eme ka ọsọ kristal dị elu, ma nwee ike ịkwalite usoro kristal shuga, na-akwalite nkewa nke molasses na kristal shuga.
