Kev ziab kom qhuav yog cov txheej txheem zoo kawg nkaus uas khaws cov ntaub ntawv los ntawm kev tshem cov dej noo thaum tswj lawv cov qauv thiab tsw. Cov txheej txheem no yog dav siv nyob rau hauv ntau yam lag luam, los ntawm kev khaws cia zaub mov mus rau kws tshuaj. Nyob rau hauv no blog, peb yuav delve rau hauv yuav ua li cas khov dryers ua hauj lwm, tsom rau lubMicro Freeze Dryer-a compact version ntawm cov tsoos freeze dryer. Peb yuav tshawb xyuas nws cov haujlwm, cov khoom tseem ceeb, thiab cov txiaj ntsig, pab koj nkag siab tias vim li cas cov cuab yeej no siv tau zoo thiab muaj txiaj ntsig.
Nkag siab txog Kev Ua Kom Qhuav Qhuav
Kev ziab kom qhuav, los yog lyophilization, yog ib txoj hauv kev siv los khaws cov ntaub ntawv pov tseg los ntawm kev tshem cov dej los ntawm sublimation. Sublimation yog txheej txheem uas cov dej khov hloov ncaj qha mus rau hauv vapor yam tsis dhau los ntawm cov kua theem. Ntawm no yog ib qho kev tawg ntawm cov txheej txheem khov-drying:
Thaum Ntxov
Kev ziab kom qhuav, lossis lyophilization, yog lub tswv yim siv los tiv thaiv cov ntaub ntawv hloov pauv los ntawm kev tshem tawm dampness los ntawm sublimation. Sublimation yog lub voj voog uas cov dej khov hloov ncaj qha mus rau hauv fume yam tsis tau mus txog theem dej. Cov txheej txheem khov-drying tuaj yeem tawg raws li hauv qab no:
Ua ntej khov
Lub voj voog pib los ntawm kev khov cov khoom, uas tuaj yeem ua txhua yam los ntawm zaub mov mus rau tshuaj. Cov khoom yog txias sai heev rau qhov kub thiab txias uas cov dej hauv nws solidifies rau hauv dej khov hauv lub tshuab ziab khaub ncaws. Vim tias nws npaj cov khoom siv rau cov theem tom ntej kom qhuav, cov kauj ruam no yog qhov tseem ceeb.
Sublimation (thaum pib ziab)
Thaum lub sij hawm qhov tseem ceeb kom qhuav, cov strain nyob rau hauv lub freeze dryer yog diminished tag nrho. Cov dej khov tuaj yeem sublimate nyob rau hauv qhov chaw qis qis, hloov ncaj qha los ntawm cov khoom mus rau cov roj. Thaum tshav kub kub yog siv los ua haujlwm nrog lub voj voog no, lav tias cov dej khov dissipates yam tsis muaj liquefying cov khoom. Cov theem no yog qhov yooj yim rau tshem tawm feem ntau ntawm cov dampness.
Desorption (secondary drying)
Lub tshuab ziab khaub ncaws khov siv cua sov ntau dua thiab txo qhov siab hauv theem thib ob kom qhuav kom tshem tau cov dej noo uas tseem nyob. Cov kauj ruam no tiv thaiv dej los ntawm kev sib sau hauv cov khoom thiab xyuas kom meej tias nws qhuav tag. Cov khoom kawg yog cov khoom qhuav, lub teeb yuag nrog kev khaws cia zoo thiab lub neej txee ntev dua.
Micro Freeze Dryer: Cov Khoom Tseem Ceeb thiab Kev Ua Haujlwm
Micro Freeze Dryer yog ib qho kev cog lus me me ntawm lub tshuab ziab khaub ncaws ib txwm muaj. Nws yog tsim los siv rau hauv kev sim, kev tsim khoom me me, lossis txawm tias siv hauv tsev. Txawm hais tias nws qhov loj me, nws ua haujlwm ntawm tib lub hauv paus ntsiab lus xws li cov tshuab ziab khaub ncaws loj dua, tab sis nrog qee qhov sib txawv raws li nws cov qauv tsim.
Cov Cheebtsam ntawm Micro Freeze Dryer
Nqus Chamber
Lub tshuab nqus tsev vacuum yog qhov chaw khov-drying tshwm sim. Nws tsim ib qho chaw tsis tshua muaj siab tsim nyog rau sublimation tshwm sim. Lub chamber feem ntau yog nruab nrog cov tais lossis rhawv qhov twg cov khoom muab tso rau.
Txias System
Lub tshuab tub yees yog lub luag haujlwm rau kev tswj xyuas qhov ntsuas kub qis uas yuav tsum tau ua rau thawj txheej txheem khov. Nws xyuas kom meej tias cov khoom yog khov ua ntej sublimation pib.
Cov phaj cua sov
Cov phaj cua sov yog siv los maj mam siv cov cua sov rau cov khoom thaum lub sij hawm sublimation. Qhov cua sov no pab txhawb kev hloov pauv ntawm cov dej khov rau hauv vapor, ua kom cov txheej txheem ziab kom zoo dua.
Tswj Vaj Huam Sib Luag
Cov tshuab ziab khaub ncaws me me niaj hnub tuaj nrog lub vaj huam sib luag tswj uas tso cai rau cov neeg siv los teeb tsa thiab saib xyuas ntau yam tsis xws li qhov kub, siab, thiab lub sijhawm ziab. Qhov no feature kom meej meej tswj cov txheej txheem ziab.
Yuav ua li cas Micro Freeze Dryer ua haujlwm
Kev ua haujlwm ntawm a Micro Freeze Dryer muaj ob peb kauj ruam:
Loading Chamber:
Cov khoom yog loaded rau hauv lub tais los yog txee rau hauv lub tshuab nqus tsev chamber. Kev npaj kom raug ua kom zoo ib yam kom qhuav.
01
khov:
Lub tshuab tub yees txias cov khoom mus rau qhov kub thiab txias qhov twg dej hauv nws solidifies rau hauv dej khov.
02
Sublimation:
Lub tshuab nqus tsev vacuum tsim ib qho chaw tsis tshua muaj siab, cia cov dej khov rau sublimate. Cov phaj cua sov siv cov cua sov kom yooj yim rau txoj haujlwm no.
03
Kev ziab kawg kawg:
Secondary drying theem ntxiv tshem tawm cov dej noo seem, kom cov khoom qhuav tag.
04
Ua tiav:
Thaum cov txheej txheem ziab kom tiav, cov khoom raug tshem tawm ntawm lub chamber. Lub tshuab ziab khaub ncaws me me rov qab mus rau qhov qub siab thiab kub, thiab lub voj voog tiav.
