Ingcaciso ye-hydrolyzate yeswekile-i-maltose acid yomoba – Ukusebenza kakuhle kwesicelo sokushicilela isihluzi se-diaphragm esizenzekelayo ngokupheleleyo

I. Imvelaphi yoMthengi

Ishishini le-biotechnology eMzantsi China, elisebenza kakhulu ekucutshungulweni okunzulu kweswekile-maltose yomoba. Inkqubo ephambili yi-sugar-maltose acid hydrolysis + fermentation. Imveliso yonyaka yeemveliso zeswekile-maltose fermentation ingaphezulu kweetoni ezingama-30,000. Ishishini elingaphezulu, emva kwe-acid hydrolysis, ukunganyamezeli, kunye nonyango lwangaphambi kwe-flocculation yeswekile-maltose yomoba, kufuneka lahlule ngokufanelekileyo izinto eziqinileyo ezixhonyiweyo kwi-sedimentary complexity ukuze kufunyanwe i-filtrate ecacileyo yokubilisa ngezantsi, ukuqinisekisa ukusebenza kweentlobo ze-fermentation kunye nobunyulu bemveliso. Ngaphambili, kwakusetyenziswa i-plate-and-frame filtration yendabuko, eyayineengxaki ezifana nomxholo wamanzi amaninzi kwi-filter cake, ukulahleka okukhulu kweswekile, ukusebenza okunzima ngesandla, kunye nomgangatho we-filtrate ongazinzileyo, okwathintela ukusebenza kakuhle kwe-fermentation kunye nolawulo lweendleko zemveliso.

II. Amanqaku eNtlungu yeNkqubo

1. Iimpawu zezinto: Emva kokuqunjelwa kolwelo lweswekile-maltose olufakwe i-asidi, kukho inani elikhulu lokungcola okucolekileyo okuxhonyiweyo, okunamasuntswana amancinci kunye nokunamathela okuqinileyo, okwenza ukwahlukana kolwelo oluqinileyo kube nzima;
2. Iimfuno zeMveliso: Umthamo wokucubungula ibhetshi umalunga neetoni ezi-2 ngebhetshi nganye, kunye nobushushu obuyi-45-55℃ kunye ne-pH ≈ 6 emva kokungaguquguquki, okufuna ukugcinwa okuzinzileyo kokungcola okuqinileyo kunye nolawulo oluqinileyo lokulahleka kweswekile;
3. Iingxaki ezikhoyo: Izixhobo zemveli zinomxholo wamanzi wekhekhe lesihluzo ongaphezulu kwama-40%, ukulahleka kweswekile yi-3%-5%, ixesha elide lokukhupha ngesandla, umjikelo omde webhetshi, ukuxinana okuphezulu kwefiltrate, kunye nokuchaphazela izinga lokuguqulwa kokubila.

III. Isisombululo

Ngokusekelwe kwiiparamitha zenkqubo yomthengi, iimpawu zezinto eziphathekayo, kunye neendawo ezibangela intlungu kwimveliso, kuyacetyiswa ukuba ukhethe i-45㎡umatshini wokucoca i-diaphragm ozenzekelayo ngokupheleleyo(ulwakhiwo olumelana ne-asidi yomgangatho wokutya), olufanele imo yayo yokuvelisa ibhetshi. Ixhomekeke kwiingenelo eziphambili zokucinezela nge-diaphragm ngoxinzelelo oluphezulu, ukusebenza ngokuzenzekelayo okulawulwa yinkqubo ye-PLC, kunye nokucoca ngokuzenzekelayo ilaphu lesihluzo, isombulula ingxaki yokwahlulwa kolwelo oluqinileyo.

IV. Isiphumo seSicelo

1. Isiphumo sokwahlulwa okuzinzileyo: I-filtrate icacile kwaye icacile, inezinga lokususa ukungcola elingaphezulu kwe-99%, ihlangabezana ngokupheleleyo neemfuno zobumsulwa bokutya kokubilisa, kwaye inciphisa kakhulu izinga lokungcola kweentlobo zokubilisa;
2. Ukulungiswa komgangatho wekhekhe lesihluzo: Umxholo oqinileyo wekhekhe lesihluzo uzinzile kwi-72%-78%, kunye nomthamo wamanzi oncitshiswe ukuya kwi-22%-28%, xa kuthelekiswa nezixhobo zemveli, uyanda ngama-15 ekhulwini, kwaye ikhekhe lesihluzo kulula ukuyithutha nokuyithutha;
3. Ukunciphisa ukulahleka kweswekile: Umthamo weswekile othwalwa yikhekhe yesihluzo ulawulwa kwi-1.0%-2.0%, kunciphisa ukulahleka kweswekile ngaphezulu kweetoni ezingama-80 ngonyaka, kunyusa ngokuthe ngqo ingeniso ngaphezulu kweeyuan ezingama-400,000;
4. Ukuphuculwa kokusebenza kakuhle kwemveliso: Umjikelo webhetshi enye ufinyezwa ube yimizuzu engama-45-60, ukusebenza ngokuzenzekelayo ngokupheleleyo, akukho mfuneko yabasebenzi abazinikeleyo yokubeka esweni, kunciphisa iindleko zabasebenzi ngama-60%, kwaye amandla okucubungula ibhetshi ayanda ngama-30%;
5. Iindleko zokusebenza ziyalawuleka: Izixhobo azina-asidi kwaye azinamhlwa, ubomi belaphu lesihluzo buyandiswa, amaxesha okugcinwa ayancipha, iindleko zokusebenza kunye nokugcinwa konyaka zincitshiswa ngama-40%, kwaye iingenelo zizonke zibalulekile.

V. Uvavanyo lwaBathengi

"I-diaphragm filter press iyisombulule ngokupheleleyo ingxaki yokucacisa i-sugarmow sugar-maltose acid hydrolyzate filtrate. Umgangatho we-filtrate uzinzile, ukufuma kwekhekhe yesihluzo kuphantsi, kwaye ukulahleka kweswekile kuncinci. Ayinciphisi nje kuphela iindleko kwaye yonyusa ukusebenza kakuhle, kodwa ikwakha isiseko esiqinileyo somgangatho kwinkqubo yokubilisa. Lukhetho olufanelekileyo lokwahlulwa kolwelo oluqinileyo kwi-deep processing ye-sugar-maltose phakathi kweswekile ne-maltose."
