Kev soj ntsuam ntawm cov xwm txheej cuam tshuam rau ziab tus nqi ntawm lub tshuab nqus tsev khov tshuab
Cov txheej txheem khov-drying yog txheej txheem cua sov thiab huab cua hloov pauv, suav nrog cov tub yees, lub tshuab nqus tsev, hluav taws xob, chemistry, tshuaj cryogenic thiab lwm yam kev qhuab qhia, nrog cov ntsiab lus siab thiab cov txheej txheem khov kom qhuav. Hauv cov tshuaj suav tshuaj, zaub mov thiab lwm yam kev lag luam, lub tshuab nqus tsev vacuum yog ib qho khoom siv nrov tshaj plaws.
Los ntawm cov qauv kev pom, lub tshuab nqus tsev khov tshuab yog kev sib xyaw ua ke ntawm cov tub yees, lub tshuab nqus tsev, lub tshuab cua sov, thiab lub tshuab ziab khaub ncaws, yog li qhia txog lub txee tshiab, uas tuaj yeem ua kom muaj txiaj ntsig zoo ntawm cov khoom siv cia hauv qhov chaw. txee. Ua kom khov lub tshuab nqus tsev kom qhuav. Tam sim no, lub tshuab nqus tsev khov yog tsim rau ziab ntau yam ntaub ntawv xws li raw cov ntaub ntawv, suav tshuaj ntsuab, tshuaj intermediates, thiab zaub mov.
Raws li kev lag luam, thaum lub tshuab nqus tsev lub tshuab ziab khaub ncaws ua haujlwm, tus nqi ziab yog qhov kev txhawj xeeb zoo rau cov neeg siv. Txawm li cas los xij, hauv kev ua haujlwm tiag tiag, nws feem ntau pom tias qhov ziab qhuav tsis txaus siab. Yog li, dab tsi yog yam uas cuam tshuam rau qhov ziab ntawm lub tshuab nqus tsev vacuum freeze dryer?
Khoom siv pre-freezing tus nqi
Nws tau nkag siab tias cov khoom siv ua ntej khov yog thawj qhov uas lub tshuab ziab khaub ncaws yuav tsum tau ua thaum nws ua haujlwm. Pre-freezing yuav muab faib ua ceev khov thiab qeeb khov. Qhov luaj li cas ntawm cov muaju tsim thaum lub sij hawm khov heev cuam tshuam rau tag nrho cov khoom ziab thiab qhov tawg ntawm cov khoom qhuav.
Tshwj xeeb, cov txheej txheem ntawm kev khov sai thiab khov qeeb muaj qhov sib txawv hauv qab no: cov dej khov nab kuab uas tsim los ntawm kev khov sai yog me dua, thiab cov dej khov nab kuab uas ua los ntawm kev khov qeeb yog loj dua. Cov dej khov loj loj yog qhov zoo rau sublimation, thaum cov dej khov me me tsis haum rau sublimation. Kev khov ceev ceev ua rau qis sublimation tus nqi thiab ceev desorption tus nqi; qeeb khov ua rau kom ceev sublimation tus nqi thiab kev daws teeb meem qeeb.
Yog li ntawd, kev lag luam tau taw qhia tias qhov ceev ntawm pre-freezing yuav tsum tau raug tuav raws li cov ntaub ntawv.
Lub siab nyob rau hauv lubkhovtshuab ziab khaub ncaws
Raws li kev lag luam, lub siab nyob rau hauv lub tshuab ziab khaub ncaws yuav cuam tshuam ncaj qha rau tus nqi ntawm tshav kub thiab huab cua hloov pauv (dej vapor). Ntawm lawv, nyob rau hauv cov nqe lus ntawm kev hloov loj, qhov qis dua qhov siab, qhov zoo dua, thiab rau kev hloov cua sov, qhov siab dua, qhov zoo dua.
Txij li thaum cov huab hwm coj hloov pauv feem ntau yog txiav txim siab los ntawm qhov kub thiab siab ntawm sublimation interface thiab saum npoo ntawm txheej ziab, kom qhov kev khiav tawm ntawm cov dej vapor hauv txheej ziab, feem ntau muaj ob txoj haujlwm: nce qhov kub ntawm sublimation. interface ua kom lub interface dej vapor Lub siab nce. Los yog ua kom lub tshuab nqus tsev ntawm lub tshuab ziab khaub ncaws thiab txo qhov vapor siab ntawm qhov chaw ziab khaub ncaws.
Khoom siv
Nws tau tshaj tawm tias nyob rau hauv cov txheej txheem kom qhuav qhuav, daim ntawv ntawm cov khoom khov qhuav yog feem ntau muab faib ua cov khoom thiab kua. Qhov ntau ntom ntawm cov khoom thiab cov khoom ntom ntom ntawm cov kua ob qho tib si cuam tshuam rau lub sijhawm khov ntawm cov khoom.
ntub hnyav load
Nws tau nkag siab tias thaum cov ntaub ntawv yog lyophilized, muaj qee qhov sib piv ntawm thaj chaw saum npoo rau cov khoom tuab tom qab tau ntim rau hauv ntim. Thaum ziab, qhov qhuav ntub qhov hnyav ntawm ib chav tsev ntawm lub tais yog qhov tseem ceeb hauv kev txiav txim siab lub sij hawm ziab.
Feem ntau, qhov thinner lub thickness ntawm cov khoom tsub zuj zuj, qhov ceev ntawm tshav kub thiab huab cua hloov ceev, thiab lub sij hawm qhuav qhuav. Txawm li cas los xij, yog tias cov khoom nyias nyias, yuav muaj cov khoom siv tsawg dua rau ib pawg ntawm ib chav tsev khov-qhuav, uas yuav ua rau muaj kev tsis zoo los ua kom lub tsev khov qhuav qhuav thiab cov khoom tawm hauv ib lub sijhawm. Yog li ntawd, kev txiav txim siab zoo yuav tsum tau ua raws li cov ntaub ntawv.
Tam sim no, muaj ntau yam khoom siv lub tshuab nqus tsev qhuav qhuav ntawm lub khw, thiab ntau lub sijhawm cov tuam ntxhab tau hloov kho thiab hloov kho lawv cov kev tswj tsis siv neeg txhawm rau txhawm rau txhim kho kev ziab kom qhuav. Qee cov tuam txhab tsim khoom tau hais tias hom tshiab ntawm cov khoom siv khov ziab qhuav tau hloov pauv qhov kev ua haujlwm tsis txaus ntseeg hauv cov txheej txheem ziab dhau los, tiv thaiv cov khoom ua qias tuaj, thiab paub txog qhov automation ntawm ziab thiab sublimation. Tus neeg saib xyuas tseem ceeb tau hais tias, "Tus qauv no muaj lub txee cua sov thiab cov haujlwm ua haujlwm tau zoo, tuaj yeem nco txog qhov khov kom qhuav nkhaus, thiab tuaj nrog U-disk extraction muaj nuj nqi, uas ua rau nws yooj yim dua los soj ntsuam cov txheej txheem khov ziab ntawm cov khoom."
