Dab tsi yog Sparger hauv Fermenter?
Hauv luv luv, ASparger hauv Fermenteryog ib qho cuab yeej siv los qhia cov cua lossis lwm yam roj rau hauv lub nkoj Fermentation.
Nws feem ntau yog cov yeeb nkab perforated nyob rau hauv qab ntawm lub nkoj los yog ze ntawm lub impeller thiab tso cai rau cov roj tso rau hauv cov kua los ntawm qhov me me los yog dav hlau.
Lub hom phiajntawm sparger yog muab cov pa oxygen rau cov txheej txheem aerobic fermentation lossis sib tov carbon dioxide (co2) rau cov txheej txheem anaerobic fermentation.lub sparger pab tswj kom muaj kev pom zoo ntawm cov pa oxygen hauv cov kab lis kev cai nruab nrab, uas yog qhov tseem ceeb rau kev loj hlob thiab cov metabolism hauv cov kab mob, xws li cov poov xab lossis cov kab mob.
Thaum lub sij hawm fermentation txheej txheem, lub sparger kuj yuav siv tau los tswj cov PH, kub thiab sib tov ntawm lub nkoj txheem.Nws yog feem ntau siv nyob rau hauv industrial-scale bioprocessing, qhov twg loj ntim ntawm cov kab mob yog kab lis kev cai ib txhij, kom ntseeg tau tias zoo ib yam thiab npaum fermentation.
Hauv thaj chaw fermentation, spargers ua lub luag haujlwm tseem ceeb hauv kev tsim qhov chaw zoo rau kev loj hlob microbial.Hauv cov ntsiab lus yooj yim, sparger yog cov cuab yeej siv los qhia cov pa roj (feem ntau yog cov pa oxygen lossis carbon dioxide) rau hauv cov kua nruab nrab.Thaum lub sij hawm fermentation, spargers feem ntau yog siv los tswj cov concentration ntawm yaj oxygen, uas yog ib qho tseem ceeb rau kev loj hlob ntawm microbial.Nyob rau hauv no blog ncej, peb mam li sib tham nyob rau hauv kom meej seb ib tug kis tau tus mob, nws ua haujlwm li cas, thiab nws qhov tseem ceeb nyob rau hauv cov txheej txheem fermentation.
Injector yog dab tsi?
Lub sparger yog ib qho cuab yeej siv los qhia cov pa roj (feem ntau yog cov pa oxygen lossis carbon dioxide) rau hauv cov kua nruab nrab.Distributors feem ntau muaj cov roj inlet thiab cov khoom ntxeem tau los faib cov pa rau hauv cov kua.Cov ntaub ntawv ntxeem tau tuaj yeem tsim los ntawm ntau yam ntaub ntawv xws li sintered hlau, ceramics lossis polymers.
Spargers feem ntau yog siv los tswj cov concentration ntawm cov pa oxygen hauv cov kua dej thaum lub sij hawm fermentation.Qhov no yog vim hais tias cov pa oxygen yog ib qho tseem ceeb rau kev loj hlob ntawm cov kab mob microbial thiab nws muaj zog cuam tshuam rau kev ceev thiab efficiency ntawm fermentation.Tsis tas li ntawd, eductors tuaj yeem siv los tswj cov pH ntawm qhov nruab nrab fermentation los ntawm kev qhia cov pa roj carbon dioxide lossis lwm cov kua qaub.
Hom ntawm distributor:
Muaj ntau ntau hom kev sib kis feem ntau siv hauv kev lag luam fermentation, txhua tus muaj nws tus kheej zoo thiab qhov tsis zoo.Feem ntau hom kab mob kis tau yog:
