Yuav ua li cas ntxuav thiab sterilize lub fermentation tank ntawm npias brewing khoom

Cov av nyob rau ntawm phab ntsa ntawm lub fermenter yog sib xyaw ntawm inorganic thiab organic teeb meem, uas yog ib qho nyuaj rau kev ntxuav nrog ib tug tu tus neeg sawv cev.Yog hais tias tsuas yog caustic soda yog siv rau fermenter tu, nws tsuas yog pab tshem tawm cov organics.Tsuas yog thaum lub ntsuas kub siab tshaj 80 ℃, tuaj yeem tau txais txiaj ntsig zoo dua;Thaum ntxuav, ib qho nitric acid yog siv los ntxuav, uas tsuas muaj qee yam cuam tshuam rau cov tshuaj inorganic thiab yuav luag tsis muaj txiaj ntsig rau cov organic.Yog li ntawd, fermenter tu yuav tsum muaj alkaline tu tov thiab ib qho acidic tu tov.
Fermentation tanks yog ntxuav ua ntej thiab ces sterilized.Qhov yuav tsum tau ua ua ntej rau kev ua kom tsis muaj menyuam yog cov av kom huv si.Hauv kev ua haujlwm tiag tiag, nws yog ib txwm ntxuav ua ntej thiab tom qab ntawd sterilized.
Ntxuav cov kauj ruam ntawm lub fermentation tank: tso cov pa roj carbon dioxide residual hauv lub tank.Compressed cua tso pa carbon dioxide rau 10-15 feeb.(nyob ntawm qhov compressed cua ntws).Cov poov xab nyob rau hauv lub fermenter yog rinsed nrog dej huv, thiab lub fermenter yog rinsed intermittently nrog dej kub ntawm 90 ° C kom sov nws.Disassemble lub tso tawm ua ke valve thiab aseptic sampling valve, siv ib tug tshwj xeeb txhuam dipped nyob rau hauv lye los ntxuav nws, thiab reinstall nws.Lub fermenter yog ntxuav los ntawm circulating kub alkaline dej tshaj 1.5-2% ntawm 80 ° C rau 30 mus rau 60 feeb.Yaug lub fermentation tank intermittently nrog dej kub los yog dej sov kom cov kua paug tawm nruab nrab, thiab intermittently yaug lub fermentation tank nrog dej txias rau chav tsev kub.Ntxuav nrog nitric acid tov nrog ib tug concentration ntawm 1% mus rau 2% rau 15 feeb.Lub fermenter tau rinsed nrog dej kom neutralize lub ntws.
Nws ntseeg tau tias los ntawm kev tu thiab tshuaj tua kab mob nruj, kev ruaj ntseg ntawm brewed npias yuav raug txhim kho ntxiv.
