Kev ua kom cov suab thaj-maltose acid hydrolyzate meej - Kev ua haujlwm zoo ntawm daim ntawv thov diaphragm lim dej tsis siv neeg tag nrho

I. Keeb Kwm ntawm Cov Neeg Siv Khoom

Ib lub tuam txhab biotechnology nyob rau sab qab teb Suav teb, feem ntau yog ua cov khoom qab zib-maltose sib sib zog nqus. Cov txheej txheem tseem ceeb yog cov qab zib-maltose acid hydrolysis + fermentation. Kev tsim cov khoom qab zib-maltose fermentation txhua xyoo yog ntau dua 30,000 tons. Sab saud ntawm lub tuam txhab, tom qab acid hydrolysis, neutralization, thiab flocculation pretreatment ntawm qab zib-maltose, yuav tsum tau cais cov khoom seem ntawm cov khoom tsis huv kom tau txais cov lim dej ntshiab rau kev fermentation downstream, xyuas kom meej tias cov kab mob fermentation thiab cov khoom huv. Yav dhau los, kev lim dej phaj-thiab-ncej ib txwm siv, uas muaj teeb meem xws li cov dej ntau hauv lub ncuav mog qab zib lim, poob qab zib ntau, kev ua haujlwm tes nyuaj, thiab qhov zoo ntawm kev lim dej tsis ruaj khov, uas cuam tshuam kev ua haujlwm fermentation thiab kev tswj tus nqi tsim khoom.

II. Cov Teeb Meem Txog Kev Ua Haujlwm

1. Cov Yam Ntxwv ntawm Cov Khoom Siv: Tom qab cov kua qaub-hydrolyzed qab zib-maltose sib xyaw ua ke, muaj ntau cov khoom tsis huv uas raug tshem tawm, nrog cov khoom me me thiab muaj zog nplaum, ua rau kev sib cais ntawm cov khoom khov thiab kua nyuaj;
2. Cov Kev Cai Tsim Khoom: Qhov ntim ua tiav yog kwv yees li 2 tons ib pawg, nrog rau qhov kub ntawm 45-55 ℃ thiab pH ≈ 6 tom qab neutralization, xav tau kev khaws cia ruaj khov ntawm cov khoom tsis huv thiab kev tswj hwm nruj ntawm kev poob qab zib;
3. Cov Teeb Meem Uas Muaj Lawm: Cov khoom siv ib txwm muaj cov dej lim ncuav mog qab zib ntau dua 40%, poob qab zib ntawm 3% -5%, lub sijhawm tshem tawm tes ntev, lub voj voog ntev, qhov lim dej turbidity siab, thiab cuam tshuam rau qhov hloov pauv fermentation.

III. Kev daws teeb meem

Raws li cov txheej txheem ntawm cov neeg siv khoom, cov yam ntxwv ntawm cov khoom siv, thiab cov teeb meem tsim khoom, nws raug pom zoo kom xaiv 45㎡tag nrho cov tshuab diaphragm lim xovxwm(khoom noj khoom haus-qib acid-resistant configuration), uas yog haum rau nws cov hom ntau lawm. Kev cia siab rau qhov zoo ntawm diaphragm high-pressure pressure, PLC program-tswj tsis siv neeg ua haujlwm, thiab tsis siv neeg lim ntaub ntxuav, nws daws qhov teeb meem ntawm kev sib cais khoom khov-kua.

IV. Cov nyhuv ntawm daim ntawv thov

1. Cov nyhuv sib cais ruaj khov: Cov lim dej yog qhov tseeb thiab pob tshab, nrog rau qhov tshem tawm cov khoom tsis huv ntau dua 99%, ua tau raws li qhov yuav tsum tau ua kom huv rau cov khoom noj fermentation, thiab txo qhov kev ua qias tuaj ntawm cov kab mob fermentation;
2. Kev ua kom zoo dua ntawm cov khoom qab zib lim: Cov ntsiab lus khov kho ntawm cov khoom qab zib lim ruaj khov ntawm 72% -78%, nrog rau cov dej ntsiab lus txo qis rau 22% -28%, piv rau cov khoom siv ib txwm muaj, nws nce ntxiv 15 feem pua, thiab cov khoom qab zib lim yooj yim rau kev tshem tawm thiab thauj mus los;
3. Kev txo qis qab zib: Cov ntsiab lus qab zib uas nqa los ntawm lub ncuav mog qab zib lim tau tswj hwm ntawm 1.0% -2.0%, txo cov qab zib poob ntau dua 80 tons hauv ib xyoos, ncaj qha nce cov nyiaj tau los ntau dua 400,000 yuan;
4. Kev txhim kho kev ua haujlwm zoo: Lub voj voog ib pawg luv dua li 45-60 feeb, ua haujlwm tsis siv neeg tag nrho, tsis tas yuav muaj cov neeg ua haujlwm tshwj xeeb los saib xyuas, txo cov nqi zog ua haujlwm los ntawm 60%, thiab muaj peev xwm ua tiav ntau ntxiv los ntawm 30%;
5. Tus nqi khiav lag luam tswj tau: Cov khoom siv yog acid-resistant thiab corrosion-resistant, lim ntaub lub neej ntev dua, kev txij nkawm zaus txo qis, kev ua haujlwm txhua xyoo thiab kev txij nkawm cov nqi txo 40%, thiab tag nrho cov txiaj ntsig yog qhov tseem ceeb.

V. Kev Ntsuam Xyuas Cov Neeg Siv Khoom

"Lub tshuab lim dej diaphragm tau daws qhov teeb meem ntawm kev ua kom cov kua qab zib-maltose acid hydrolyzate filtrate meej. Qhov zoo ntawm cov dej lim ruaj khov, cov dej noo ntawm cov ncuav mog qab zib tsawg, thiab qhov poob qab zib me me. Nws tsis tsuas yog txo cov nqi thiab ua kom muaj txiaj ntsig zoo dua, tab sis kuj tsim kom muaj lub hauv paus ruaj khov rau qhov zoo hauv cov txheej txheem fermentation. Nws yog qhov kev xaiv zoo tshaj plaws rau kev sib cais cov khoom khov-kua hauv cov kua qab zib-maltose sib sib zog nqus."
