Tso lus
Kev ziab kom qhuav, lossis lyophilization, yog ib txoj hauv kev siv los khaws cov ntaub ntawv los ntawm kev tshem cov dej los ntawm sublimation. Cov txheej txheem no yog siv dav rau kev khaws cia zaub mov, tshuaj, thiab ntau yam kev siv. Kev nkag siab ntev npaum li cas lub tshuab ziab khaub ncaws yuav siv sij hawm los ua kom tiav nws lub voj voog yog qhov tseem ceeb rau kev npaj tau zoo thiab cov txiaj ntsig zoo. Nyob rau hauv no blog, peb yuav delve rau hauv lub sij hawm xav txog kev koom tes nyob rau hauv khov qhuav, nrog ib tug tshwj xeeb tsom rau lub Micro Freeze Dryer-a compact tsis tau npaum version ntawm cov khoom siv khov-drying ib txwm muaj.
Cov txheej txheem khov ziab qhuav thiab lub sijhawm yuav tsum tau ua
Kev ziab kom qhuav muaj peb theem pib: khov, sublimation, thiab desorption. Txhua theem muaj nws tus kheej lub sijhawm yuav tsum tau ua thiab txhawb nqa lub sijhawm tag nrho ntawm cov txheej txheem. Cia peb tshawb xyuas txhua theem kom nkag siab tias lub tshuab ziab khaub ncaws yuav siv sijhawm ntev npaum li cas los ua kom tiav tag nrho lub voj voog.
Txias theem
Thawj theem ntawm khov ziab yog khov, qhov twg cov khoom yog txias mus rau qhov kub thiab txias qhov twg tag nrho cov ya raws nyob rau hauv nws solidifies rau hauv dej khov. Lub sijhawm xav tau rau theem no nyob ntawm ntau yam:
Hom thiab ntim: Cov khoom sib txawv thiab ntim yuav khov ntawm cov nqi sib txawv. Piv txwv li, kua thiab nyias txheej khov sai dua li cov ntaub ntawv tuab lossis tuab.
Lub Freezer Temperature: Qhov kub ntawm qhov qis dua, qhov kev ua kom khov sai dua. Txawm li cas los xij, qhov kub tsis tshua muaj siab yuav xav tau sijhawm ntxiv kom ua tiav.
Kev Kub Kub Thaum Ntxov ntawm Cov Khoom Siv: Cov khoom uas pib ntawm qhov kub siab dua yuav siv sijhawm ntev dua kom khov.
Feem ntau, lub sijhawm khov tuaj yeem siv sijhawm nyob qhov twg los ntawm ob peb teev mus rau ib hnub lossis ntau dua, nyob ntawm cov xwm txheej no. Cov khoom me me hauv Micro Freeze Dryer feem ntau yuav khov sai dua piv rau cov khoom loj hauv cov kab ke loj dua.
Sublimation theem
Thaum cov khoom yog khov, lub sublimation theem pib. Qhov no yog qhov uas cov dej khov hloov ncaj qha los ntawm cov khoom mus rau ib qho vapor yam tsis tau dhau los ntawm cov kua theem. Lub sijhawm xav tau rau sublimation yog cuam tshuam los ntawm:
Khoom siv:
Qhov tshwj xeeb kub thiab thermal conductivity ntawm cov khoom yuav cuam tshuam sai npaum li cas sublimation tshwm sim.
Lub tshuab nqus tsev siab:
Tsawg siab ua kom yooj yim sublimation. Lub tshuab ziab khaub ncaws me me tswj lub tshuab nqus tsev los txhawb txoj haujlwm no.
Kev siv cua sov:
Kev tswj cov cua sov yog siv rau cov khoom siv los txhawb sublimation. Tus nqi ntawm qhov kev siv cua sov no tuaj yeem cuam tshuam rau lub sijhawm xav tau.
Cov theem sublimation feem ntau yog siv sijhawm ntau ntawm kev ziab kom qhuav. Rau lub tshuab ziab khaub ncaws me me, sublimation tuaj yeem siv nyob qhov twg los ntawm 24 mus rau 72 teev, nyob ntawm cov khoom siv thiab kev teeb tsa.
Desorption theem
Qhov kawg theem, desorption, suav nrog tshem tawm cov dej noo seem uas yuav raug daig hauv cov khoom. Cov theem no ua kom cov khoom kom qhuav thiab npaj rau kev cia. Lub sijhawm xav tau rau desorption tuaj yeem sib txawv raws li:
Cov ntaub ntawv noo noo:
Cov dej noo ntau dua yuav xav tau sijhawm ntxiv kom tshem tawm tag nrho.
Kub thiab Siab:
Me ntsis kub dua yog siv los tsav tawm cov dej seem seem. Lub sijhawm xav tau yuav nyob ntawm seb cov xwm txheej no tswj tau zoo npaum li cas.
Micro Freeze Dryer
Feem ntau, desorption yuav siv li ob peb teev kom tiav. Rau lub tshuab ziab khaub ncaws me me, theem no yuav luv dua piv rau cov qauv loj, feem ntau ntawm 6 mus rau 12 teev.
Yam Tseem Ceeb cuam tshuam rau Lub Sijhawm Qhuav Qhuav
Ntau yam tuaj yeem cuam tshuam tag nrho lub sijhawm xav tau rau kev ziab kom khov, tshwj xeeb tshaj yog nyob rau hauv Micro Freeze Dryer. Kev nkag siab txog cov xwm txheej no tuaj yeem pab txhim kho cov txheej txheem thiab ua tiav cov txiaj ntsig xav tau zoo.
