Ukucaciswa kwe-hydrolyzate kashukela-i-maltose acid yomoba – Ukusebenza kahle kohlelo lokusebenza lokucindezela isihlungi se-diaphragm oluzenzakalelayo ngokuphelele

I. Isizinda Samakhasimende

Ibhizinisi le-biotechnology eNingizimu yeShayina, elibandakanyeka kakhulu ekucutshungulweni okujulile kweshukela-maltose yomoba. Inqubo eyinhloko i-sugar-maltose acid hydrolysis + fermentation yomoba. Ukukhiqizwa kwaminyaka yonke kwemikhiqizo yokuvutshelwa kweshukela-maltose kungaphezu kwamathani angu-30,000. Ingxenye engenhla yebhizinisi, ngemva kwe-acid hydrolysis, ukungathathi hlangothi, kanye nokwelashwa kwangaphambili kweshukela-maltose yomoba, idinga ukuhlukanisa kahle izinto eziqinile ezimisiwe nokungcola okungcolile ukuze kutholakale i-filtrate ecacile yokuvutshelwa phansi, kuqinisekiswe ukusebenza kwezinhlobo zokuvutshelwa kanye nokuhlanzeka komkhiqizo. Ngaphambilini, kwakusetshenziswa ukuhlunga kwendabuko kwepuleti nohlaka, okwakunezinkinga ezifana nokuqukethwe kwamanzi amaningi ekhekheni lokuhlunga, ukulahlekelwa ushukela okukhulu, ukusebenza okunzima ngesandla, kanye nekhwalithi yokuvutshelwa engazinzile, okwavimbela ukusebenza kahle kokuvutshelwa kanye nokulawulwa kwezindleko zokukhiqiza.

II. Amaphuzu Obuhlungu Benqubo

1. Izici Zezinto: Ngemva kokucwiliswa koketshezi lwe-sugar-maltose olufakwe i-asidi, kuba nenani elikhulu lokungcola okunciphile okulengayo, okunezinhlayiya ezincane kanye nokunamathela okuqinile, okwenza kube nzima ukuhlukaniswa koketshezi oluqinile;
2. Izidingo Zokukhiqiza: Umthamo wokucubungula inqwaba cishe ungamathani ama-2 ngenqwaba ngayinye, kanye nokushisa okungu-45-55℃ kanye ne-pH ≈ 6 ngemva kokuncishiswa, okudinga ukugcinwa okuzinzile kokungcola okuqinile kanye nokulawulwa okuqinile kokulahleka kukashukela;
3. Izinkinga Ezikhona: Imishini yendabuko inokuqukethwe kwamanzi ekhekheni lokuhlunga okungaphezu kuka-40%, ukulahlekelwa ushukela okungu-3%-5%, isikhathi eside sokukhipha ngesandla, umjikelezo omude we-batch, ukugcwala okuphezulu kwe-filtrate, futhi kuthinta izinga lokuguqulwa kokubilisa.

III. Isixazululo

Ngokusekelwe kumapharamitha enqubo yekhasimende, izici zezinto ezibonakalayo, kanye namaphuzu obunzima bokukhiqiza, kunconywa ukukhetha i-45㎡umshini wokuhlunga we-diaphragm ozenzakalelayo ngokuphelele(ukucushwa okumelana ne-asidi yezinga lokudla), okufanelekela imodi yayo yokukhiqiza inqwaba. Ithembele ezinzuzweni eziyinhloko zokucindezela okuphezulu kwe-diaphragm, ukusebenza okuzenzakalelayo okulawulwa uhlelo lwe-PLC, kanye nokuhlanza indwangu yokuhlunga okuzenzakalelayo, ixazulula inkinga yokuhlukaniswa koketshezi oluqinile.

IV. Umphumela Wokusetshenziswa

1. Umphumela wokuhlukaniswa okuzinzile: I-filtrate icacile futhi isobala, inezinga lokususa ukungcola elingaphezu kuka-99%, ihlangabezana ngokugcwele nezidingo zobumsulwa bokudla kokubilisa, futhi inciphisa kakhulu izinga lokungcoliswa kwezinhlobo zokubilisa;
2. Ukwenziwa ngcono kwekhwalithi yekhekhe lesihlungi: Okuqukethwe okuqinile kwekhekhe lesihlungi kuzinzile ku-72%-78%, kanti okuqukethwe kwamanzi kwehliswe ku-22%-28%, uma kuqhathaniswa nemishini yendabuko, kukhuphuka ngamaphesenti ayi-15, futhi ikhekhe lesihlungi kulula ukulithutha nokulithutha;
3. Ukunciphisa ukulahleka kukashukela: Okuqukethwe kukashukela okuthwalwa yikhekhe lesihlungi kulawulwa ku-1.0%-2.0%, kunciphisa ukulahleka kukashukela ngamathani angaphezu kuka-80 ngonyaka, okwandisa ngqo imali engenayo ngama-yuan angaphezu kuka-400,000;
4. Ukuthuthukiswa kokusebenza kahle kokukhiqiza: Umjikelezo we-batch eyodwa ufinyezwa ube yimizuzu engama-45-60, ukusebenza okuzenzakalelayo ngokuphelele, asikho isidingo sabasebenzi abazinikele ukuqapha, kunciphisa izindleko zabasebenzi ngo-60%, kanye nomthamo wokucubungula i-batch ukhuphuka ngo-30%;
5. Izindleko zokusebenza ziyalawuleka: Imishini imelana ne-asidi futhi imelana nokugqwala, impilo yendwangu yokuhlunga iyandiswa, imvamisa yokulungisa iyancishiswa, izindleko zokusebenza nokulungisa zonyaka ziyancishiswa ngo-40%, kanti izinzuzo zizonke zibalulekile.

V. Ukuhlolwa Kwamakhasimende

"Umshini wokuhlunga we-diaphragm uxazulule ngokuphelele inkinga yokucacisa i-sugar-maltose acid hydrolyzate filtrate yomoba. Ikhwalithi ye-filtrate izinzile, umswakama wekhekhe lesihlungi uphansi, futhi ukulahleka kukashukela kuncane. Akugcini nje ngokunciphisa izindleko futhi kwandise ukusebenza kahle, kodwa futhi kwakha isisekelo esiqinile sekhwalithi enqubweni yokubilisa. Kuyisinqumo esifanele sokuhlukaniswa koketshezi oluqinile ekucutshungulweni okujulile koshukela-maltose womoba."
