Hauv kev tsim cov npias, kev lim dej thiab kev ua kom tsis muaj menyuam yuav tsum tau ua.Lub hom phiaj ntawm kev pom yog tshem tawm cov poov xab thiab lwm yam turbid nyob rau hauv npias thaum lub sij hawm fermentation txheej txheem, xws li hop resin, tannin, poov xab, lactic acid kab mob, protein thiab lwm yam impurities, thiaj li los txhim kho lub pob tshab ntawm npias thiab txhim kho. lub aroma thiab saj ntawm npias.Lub hom phiaj ntawm kev ua kom tsis muaj menyuam yog tshem tawm cov poov xab, kab mob thiab kab mob, tshem tawm cov tshuaj tiv thaiv fermentation, xyuas kom muaj kev nyab xeeb ntawm kev haus npias thiab ua kom lub neej ntev.Tam sim no, membrane sib cais tshuab rau kev pom thiab sterilization ntawm npias tau dhau los ua ib qho tshiab.Niaj hnub no, tus editor ntawm Shandong Bona Group yuav qhia txog daim ntawv thov ntawm daim nyias nyias nyias tshuab hauv npias pom thiab ua kom tsis muaj menyuam.
Membrane sib cais tshuab siv hauv kev tsim npias tuaj yeem tsis tsuas yog khaws cov tsw thiab khoom noj khoom haus ntawm npias, tab sis kuj txhim kho kom meej meej ntawm npias.Cov cua ntsawj ntshab lim dej los ntawm cov khoom siv tsis zoo hauv daim nyias nyias yeej tswj tau qhov tsw ntawm npias tshiab, lub hop aroma, iab thiab tuav kev ua tau zoo yog qhov tsis muaj kev cuam tshuam, thaum lub turbidity txo qis, feem ntau qis dua 0.5 turbidity units, thiab cov kab mob khaws cia nyob ze rau. 100%.Txawm li cas los xij, vim tias cov lim dej tsis tuaj yeem tiv taus qhov sib txawv siab qhov sib txawv, yuav luag tsis muaj cov nyhuv adsorption, yog li cov kua cawv yuav tsum tau ua kom zoo ua ntej lim kom tshem tawm cov khoom loj thiab cov tshuaj macromolecular colloidal.Tam sim no, cov lag luam feem ntau siv cov tshuab microporous membrane filtration rau cov txheej txheem tsim cov npias.
Microfiltration membrane filtration technology yog siv nyob rau hauv peb yam nram qab no hauv npias ntau lawm:
1. Hloov kho cov txheej txheem lim ib txwm.Cov txheej txheem filtration ib txwm yog tias fermentation broth yog coarsely lim los ntawm diatomaceous ntiaj teb thiab ces finely lim los ntawm cardboard.Tam sim no, daim nyias nyias tuaj yeem siv los hloov cov duab los qhia zoo pom, thiab cov nyhuv lim dej zoo dua, thiab qhov zoo ntawm cov kua txiv hmab txiv ntoo zoo dua.
2. Pasteurization thiab kub instantaneous sterilization yog ib txoj hauv kev los txhim kho lub sijhawm zoo ntawm npias.Tam sim no txoj kev no tuaj yeem hloov tau los ntawm microfiltration membrane technology.Qhov no yog vim hais tias qhov pore loj ntawm lub lim membrane xaiv nyob rau hauv cov txheej txheem filtration yog txaus los tiv thaiv cov kab mob kis los ntawm, thiaj li yuav tshem tawm cov pa phem microorganisms thiab residual poov nyob rau hauv npias, thiaj li mus txhim kho lub txee lub neej ntawm npias.Vim tias daim nyias nyias tsis txhob muaj qhov kub thiab txias rau qhov saj thiab khoom noj khoom haus ntawm cov npias tshiab, cov npias uas tsim muaj cov saj zoo dua, uas feem ntau hu ua "npias tshiab".
3. Npias yog ib qho dej haus raws caij nyoog.Kev thov tshwj xeeb yog siab heev nyob rau lub caij ntuj sov thiab lub caij nplooj zeeg.Txhawm rau ua kom tau raws li qhov xav tau ntawm kev ua lag luam, ntau lub tuam txhab siv cov txheej txheem tom qab dilution ntawm high-concentration fermentation broth kom nthuav dav ntau lawm.Qhov zoo ntawm cov dej tsis muaj menyuam thiab CO2 roj tsim nyog rau tom qab dilution ntawm npias yog ncaj qha ntsig txog qhov zoo ntawm npias.CO2 xav tau rau kev tsim cov breweries feem ntau yog rov qab ncaj qha los ntawm lub fermenter, nias rau hauv "dej khov" thiab tom qab ntawd siv.Nws yuav luag tsis muaj kev kho mob, Yog li ntawd cov ntsiab lus impurity siab.Cov dej tsis huv uas xav tau rau tom qab dilution feem ntau yog siv nrog cov ntaub ntawv lim dej zoo tib yam, thiab feem ntau nyuaj kom ua tau raws li cov cai ntawm cov dej tsis muaj menyuam.Qhov tshwm sim ntawm cov tshuab lim membrane yog ib qho kev daws teeb meem zoo rau cov tuam txhab los daws qhov teeb meem no.Nyob rau hauv cov dej kho los ntawm cov lim membrane, tus naj npawb ntawm Escherichia coli thiab txhua yam kab mob lwm yam yog pib tshem tawm.Tom qab cov pa roj carbon monoxide tau ua tiav los ntawm cov lim membrane, qhov purity tuaj yeem ncav cuag ntau dua 95%.Tag nrho cov txheej txheem no muab kev lees paub txhim khu kev qha rau kev txhim kho cov cawv txiv hmab zoo.
Kev siv cov txheej txheem kev sib cais ntawm daim nyias nyias tuaj yeem ua kom tsis muaj kua txiv hmab txiv ntoo, tshem tawm turbidity, txo cov cawv concentration, ua kom pom tseeb ntawm cawv, tswj cov xim, aroma thiab saj ntawm cov cawv txiv hmab, thiab ua kom lub neej ntev ntawm cov cawv txiv hmab.Membrane sib cais tshuab tau dav siv hauv npias.hauv kev tsim khoom.BONA tsom rau kev daws teeb meem xws li kev xav thiab pom hauv cov txheej txheem ntawm cov dej haus / cog extraction / tsoos suav tshuaj npaj / fermentation broth / vinegar thiab soy sauce, thiab lwm yam, thiab muab cov neeg muas zaub nrog tag nrho cov kev sib cais thiab purification tov.Yog tias koj muaj kev sib cais thiab kev huv Yog tias tsim nyog, thov koj xav tiv tauj peb, Shandong Bona Group tos ntsoov yuav koom tes nrog koj!
