"Decolorizing uye Deodorizing Master" muIndasitiri yeShugaⅠ
Mumunda wechikafu nechinwiwa indasitiri, indasitiri yeshuga ndeimwe yenzvimbo dzakakosha dzekushandiswa kweiyo activated kabhoni. Munguva yekugadzirwa kwemhando dzeshuga dzakadai senzimbe, shuga yebhiti, starch shuga, maltose, lactose, molasses, xylose, xylitol, glucose, uye hydrolyzed protein solution, activated carbon inoita basa rinokosha mukubvisa ruvara uye deodorization.
Mafekitari eshuga akakamurwa kuita mafekitari enzimbe uye mafekitori eshuga yebhiti. Mhinduro yeshuga ine zvinhu zvakasiyana-siyana zvemavara se melanoidins, caramel, uye iron-polyphenol complexes. Activated kabhoni, ine nzvimbo yakakura yepasi (500 - 1500m²/g) uye yakapfuma chimiro chemesopores uye micropores, inogona kuratidza yakanaka adsorption kuita uye yakakwirira decolorization kunyatsoita kana uchibata neshuga mhinduro.
Kune akawanda mamicropores mukati meakabatidzwa kabhoni zvidimbu, uye saizi yepore yakakura kwazvo, kubva kune mashoma angstroms kusvika akati wandei mamicrometer. Kunyanya, kune huwandu hukuru hwema micropores ane saizi yepore muhuwandu hweashoma kusvika akati wandei makumi e angstroms. Imwe neimwe yeaya mamicropores inoenderana neimwe nzvimbo, ichiita iyo yakazara chaiyo nzvimbo yeyakagadzirwa kabhoni inoshamisa. Kune 1 giramu yeakabatidzwa kabhoni ine basa rakanakisa, nzvimbo yayo chaiyo inogona kusvika 1000m². Nekuti iyo atomiki simba munda uri pamusoro peiyo activated kabhoni iri munzvimbo isina unsaturated uye kune yakasara valence masimba, zvichibva pane yakakura kudaro nzvimbo yepasi, simba rayo repamusoro rakakosha zvakanyanya. Izvo chaizvo nekuda kweiyo adsorption mhedzisiro iyo iyo unsaturated simba munda uri pamusoro peiyo activated kabhoni inogona kubhadharwa kune imwe nhanho, nekudaro ichidzikisa pasi simba. Naizvozvo, pasi petembiricha chaiyo uye kudzvanywa kwemamiriro, pamusoro peiyo activated kabhoni inozozvishambadza otomatiki zvinhu zvinogona kuderedza simba rayo repamusoro. Nekudaro, kana yakabatidzwa kabhoni inoshambadza zvinhu zvakasiyana kubva mumhinduro, huwandu hweadsorption hahuenderane nehuwandu hwezvinhu izvi mumhinduro. Activated kabhoni inogara ichiita kuti iyo solute concentration pane adsorption iwedzere kuenzana. Neiyi nzira, kunyangwe kana iyo adsorption kugona yakafanana, izvo zvisiri-shuga zvinhu zvine yakaderera concentration mumushonga weshuga zvinonyanya kushambadzwa neyakagadzirwa kabhoni zvichienzaniswa ne sucrose ine yakakwira concentration. Zvinhu zvine mavara zviri musyrup zvinowanzova nevhoriyamu yakakura zvakati wandei uye huremu hwakati kurei. Kuburikidza neiyo adsorption yeyakagadzirwa kabhoni, simba rayo repamusoro rinodzikiswa kusvika pamwero mukuru, uye sirasi inobatwa neyakagadzirwa kabhoni inogona kuwana yakakura dhigirii yekubvisa. Izvo chaizvo nekuti activated kabhoni ine yakanakisa decolorization uye yekuchenesa kugona kwesyrup iyo yakashandiswa zvakanyanya uye zvinobudirira mumaindasitiri eshuga epamusoro kunze kwenyika.
Kana activated kabhoni inoshandiswa kurapa shuga mhinduro, mukuwedzera kune yakakosha decolorization mhedzisiro, inogona zvakare kubvisa colloids uye pamusoro - inoshanda tsvina mune shuga mhinduro. Iyi nzira inowedzera kushushikana kweiyo shuga mhinduro, kuderedza viscosity yayo, kuderedza furo chizvarwa panguva yekubuda evaporation, kuwedzera crystallization kukurumidza, uye inogona kukwidziridza iyo shuga crystallization process, kusimudzira kupatsanurwa kwemamolasses kubva kune shuga makristasi.
