Lub tshuab nqus tsev khov, tseem hu ua lyophilizer lossis lub tshuab ziab khaub ncaws khov, yog siab -precision low-kub dehydration processing equipment tshwj xeeb uas siv rau khov- ziab thiab lyophilization ntau lawm khoom noj, tshuaj thiab tshuaj lom neeg cov qauv. Nws txoj hauv kev ua haujlwm tseem ceeb yog ua raws li lub cev sublimation yam ntxwv ntawm cov dej hauv qab qis - lub tshuab nqus tsev ib puag ncig, uas txawv kiag li ntawm cov cua kub evaporation dehydration logic ntawm cov khoom siv cua kub ib txwm siv. Sublimation txhais tau hais tias cov dej khov hloov ncaj qha mus rau hauv dej vapor yam tsis muaj theem ua kua, qhov kev hloov pauv lub cev tshwj xeeb no txiav txim siab txhua qhov zoo ntawm khov- tshuab ziab khaub ncaws. Lub voj voog ua tiav lyophilization ntawm cov txheej txheem kev lag luam khov tshuab tau muab faib ua peb theem txuas ntxiv: ua ntej-kev kho kom khov, thawj sublimation ziab thiab theem nrab desorption ziab. Nyob rau hauv lub sijhawm ua ntej- khov, lub tshuab ziab khaub ncaws lub tub yees txias sai sai txo qhov kub ntawm cov khoom siv hauv qab ntawm eutectic point, tag nrho cov dej dawb hauv cov ntaub ntawv raw yog hloov mus rau hauv cov dej khov khov kom tsis txhob muaj cov kua dej melting puas tsuaj rau cov ntaub so ntswg hauv kev ua haujlwm tom ntej. Lub sijhawm ua ntej-kub khov thiab tuav lub sijhawm ntawm lub rooj zaum- lub tshuab ziab khaub ncaws sab saum toj thiab cov lyophilizer loj loj tau hloov kho raws li cov khoom siv raw khoom sib txawv eutectic cov ntsiab lus. Tom qab ua ntej- khov ua tiav, lub tshuab nqus tsev ntawm lub tshuab nqus tsev lub tshuab ziab khaub ncaws pib txuas ntxiv tshem tawm cua hauv lub tshuab ziab khaub ncaws kom ruaj khov qis- qhov siab tsis zoo ib puag ncig. Nyob rau hauv lub tshuab nqus tsev no, cov dej khov hauv cov khoom siv raw tuaj yeem ncaj qha sublimate rau hauv dej vapor yam tsis tau yaj rau hauv cov dej ua kua, tag nrho cov txheej txheem yog hu ua khov- ziab lossis lyophilization. Cov dej vapor generated los ntawm sublimation yog sai sai ntes thiab condensed los ntawm lub txias ntxiab system ntawm lyophilizer thiab tawm tawm ntawm lub drying chamber kom lub nqus tsev vacuum ruaj khov. Lub rooj ntev zaum- lub tshuab ziab khaub ncaws saum toj kawg nkaus thiab cov khoom lag luam loj lyophilizer ua raws li qhov khov kho tib yam - ziab lub cev, qhov sib txawv tsuas yog nyob rau hauv cov khoom ntim, kev ua haujlwm txhua hnub lyophilization muaj peev xwm thiab tsis siv neeg tswj qib. Cov tsoos siab- qhov kub kom qhuav tso siab rau cov cua kub kom evaporate cov dej, uas yuav rhuav tshem cov cua sov- cov khoom rhiab heev, xim thiab tsw ntawm cov ntaub ntawv raw; Thaum qhov qis- qhov kub ntawm lub tshuab nqus tsev ua haujlwm ib puag ncig ntawm lub tshuab ziab khaub ncaws tuaj yeem kaw yuav luag tag nrho cov khoom siv raw ntawm cov khoom siv raw, qhov no yog qhov tseem ceeb tshaj plaws ntawm lyophilization technology dav lees paub los ntawm cov chaw tsim khoom thoob ntiaj teb. Rau siab -tus nqi tshav kub- cov ntaub ntawv raw, lub tshuab nqus tsev khov tshuab lyophilizer yog cov khoom siv ua tsis tau.
