Taw qhia
Lub tshuab ziab khaub ncaws khov (lyophilizer) yog ib qho tseem ceeb ntawm cov cuab yeej siv los tshem tawm cov dej noo ntawm cov ntaub ntawv thaum khaws cov qauv thiab cov khoom sib txuas. Tsis zoo li cov txheej txheem ziab khaub ncaws, khov ziab ua haujlwm nyob rau hauv lub tshuab nqus tsev thiab tsis kub, ua rau nws zoo tagnrho rau cov khoom rhiab heev.
Txias kom qhuav txheej txheem
Lub freeze drying txheej txheem muaj peb theem tseem ceeb:
1. Lub caij khov (H3)
Cov khoom yog thawj khov ntawm qhov kub thiab txias kom hloov dej mus rau hauv cov dej khov khov. Kev khov kho kom zoo ua kom zoo ib yam sublimation thiab tiv thaiv kev sib tsoo.
2.Primary Drying (Sublimation)
Nyob rau hauv lub tshuab nqus tsev, cov dej khov sublimates ncaj qha rau hauv vapor. Cov theem no tshem tawm feem ntau ntawm cov dej noo thiab yuav tsum tau tswj xyuas qhov siab thiab kub.
3.Secondary Drying (Desorption)
Residual noo noo yog tshem tawm los ntawm me ntsis nce qhov kub thiab txias, ua tiav qhov kawg dryness.
Cov Kev Ua Haujlwm Tseem Ceeb
- Temperature: Txee qhov kub thiab txias tswj lub zog nkag
- Nqus Theem: Feem ntau qis dua 100 mTorr rau sublimation zoo
- Lub Sijhawm Qhuav: Nyob ntawm cov khoom tuab thiab cov ntsiab lus noo noo
- Qhov ntsuas kub kub: Feem ntau ntawm -40℃txog -80 degree
Kev teeb tsa tsis zoo yuav ua rau kom qhuav tsis tiav lossis cov khoom tawg.
Daim ntawv thov
Freeze dryers yog dav siv hauv:
- Kev ua zaub mov (txiv hmab txiv ntoo, kas fes, npaj zaub mov)
- Pharmaceuticals (cov tshuaj tiv thaiv, enzymes)
- Botanical khoom (tshuaj ntsuab extracts)
Xaus
Kev nkag siab txog cov txheej txheem khov kom qhuav yuav pab txhim kho cov khoom zoo thiab lub zog ua haujlwm. Nrog rau kev thov ntau ntxiv rau cov khoom muaj txiaj ntsig siab, lub tshuab ziab khaub ncaws khov tau dhau los ua cov cuab yeej tseem ceeb hauv kev lag luam niaj hnub.
