Raws li cov khoom siv lub cev qhuav dej, qis-kub khov tshuab ziab khaub ncaws, nrog rau lawv cov ntsiab lus tshwj xeeb thiab qhov zoo, tau siv dav hauv ntau yam xws li biopharmaceuticals, kev ua zaub mov, thiab cov khoom siv tshuaj. Lawv tsis tsuas yog tshem tawm cov dej noo los ntawm cov ntaub ntawv zoo xwb tab sis kuj ua kom muaj txiaj ntsig zoo ntawm kev khaws cov khoom xyaw thiab cov qauv qub nyob rau hauv qis- qhov kub thiab txias, muab kev txhawb zog rau kev tsim ntau yam siab - tus nqi- ntxiv cov khoom.
Lub hauv paus ntsiab lus tseem ceeb ntawm qis -kub khov tshuab ziab khaub ncaws yog nyob ntawm peb lub xeev dej. Nyob rau hauv qis- qhov kub thiab txias, cov dej noo hauv cov khoom yog thawj zaug khov rau hauv cov dej khov. Tom qab ntawd, nyob rau hauv lub tshuab nqus tsev, cov dej khov nab kuab ncaj qha hloov mus rau hauv dej vapor los ntawm sublimation thiab muab rho tawm los ntawm lub cev, yog li ua tiav lub cev qhuav dej thiab ziab ntawm cov khoom. Tus yuam sij rau txoj kev no yog sublimation, qhov twg cov dej khov ncaj qha hloov mus rau hauv lub xeev gaseous yam tsis dhau los ntawm lub xeev ua kua. Vim tias tag nrho cov txheej txheem tshwm sim nyob rau hauv qhov qis - qhov kub thiab lub tshuab nqus tsev ib puag ncig, cua sov- cov khoom rhiab hauv cov khoom raug tiv thaiv zoo, tsis txhob denaturation lossis degradation tshwm sim los ntawm qhov kub thiab txias los yog cov tshuaj lom neeg muaj zog heev.
Txoj kev ua kom lub cev qhuav dej tshwj xeeb no coj tau ntau yam txiaj ntsig zoo rau qis -kub khov tshuab ziab khaub ncaws. Ua ntej, nws ua kom lub cev qhuav dej zoo heev. Nyob rau hauv ib qho chaw nqus tsev vacuum, qhov diffusion tus nqi ntawm cov pa vapor accelerates, thiab sublimation tus nqi ntawm cov dej khov muaju yog nce, thiab shortening lub sij hawm kom qhuav. Nyob rau tib lub sijhawm, vim tias cov khoom tseem nyob ruaj khov ntawm qhov kub thiab txias, cov txheej txheem ziab kom zoo dua qub, tsis txhob muaj teeb meem xws li overheating hauv zos los yog ziab tsis sib xws uas yuav tshwm sim hauv cov txheej txheem ziab khaub ncaws, ua kom cov khoom zoo ib yam.
Thib ob, qis -kub khov tshuab ziab khaub ncaws muaj kev ruaj ntseg siab. Thaum lub sijhawm ua haujlwm, kev tswj xyuas qhov kub thiab qhov nqus tau zoo tiv thaiv oxidation, deterioration, lossis kev puas tsuaj rau cov ntaub ntawv thaum ziab. Piv txwv li, nyob rau hauv biopharmaceutical teb, ntau cov proteins thiab enzymes yog heev rhiab heev rau kub; Lub tshuab ziab khaub ncaws khov tuaj yeem khaws lawv cov kev ua haujlwm lom neeg ntawm qhov kub thiab txias, tswj lawv cov kev ua haujlwm siab thiab ruaj khov hauv cov ntawv thov tom ntej.
Tsis tas li ntawd, freeze dryers muaj kev hloov tau zoo heev. Lawv tuaj yeem ua cov ntaub ntawv ntau yam, suav nrog cov khib nyiab, kua, thiab hmoov, thiab cov txheej txheem tsis tuaj yeem hloov kho raws li cov khoom sib txawv kom ua tiav cov txiaj ntsig kom qhuav. Qhov kev hloov pauv no tso cai rau lub tshuab ziab khaub ncaws kom ua tau zoo hauv ntau qhov kev lag luam, ua tau raws li kev xav tau ntau lawm.
Hauv kev siv cov tswv yim, kev ua haujlwm siab thiab ruaj khov ntawm cov tshuab ziab khaub ncaws ua rau cov txiaj ntsig tseem ceeb rau cov neeg siv. Noj cov zaub mov kev lag luam ua piv txwv, cov khoom noj khov uas tsim los siv qis -kub freeze- tshuab ziab khaub ncaws tuaj yeem tsis tsuas yog khaws cia rau lub sijhawm ntev, tab sis kuj tseem muaj cov saj zoo sib xws thiab cov khoom noj khoom haus zoo sib xws rau cov khoom noj tshiab tom qab rehydration, ua rau kom tus nqi ntxiv ntawm cov khoom. Hauv thaj chaw biopharmaceutical, qis-kub khov tshuab ziab khaub ncaws muab kev ruaj ntseg zoo rau kev tsim cov tshuaj tiv thaiv, tshuaj lom neeg lom neeg, thiab lwm yam khoom lag luam, ua kom zoo thiab ruaj khov ntawm cov khoom muaj txiaj ntsig zoo.
Hauv luv luv, qis-kub khov tshuab ziab khaub ncaws, nrog rau lawv cov ntsiab cai tshwj xeeb thiab qhov zoo ntawm qhov tseem ceeb, tau ua kom pom qhov muaj peev xwm loj thiab muaj txiaj ntsig hauv kev ua kom lub cev qhuav dej. Lawv tuaj yeem tsis tsuas yog ua tau zoo thiab ruaj khov tshem tawm cov dej noo los ntawm cov ntaub ntawv, tab sis kuj khaws cov khoom xyaw nquag thiab cov qauv qub ntawm cov ntaub ntawv mus rau qhov siab tshaj plaws nyob rau hauv qis - qhov kub thiab txias, muab kev txhawb zog rau kev tsim ntau yam siab - nqi- ntxiv cov khoom.
