Freeze drying, tseem hu ua freeze drying, yog txheej txheem uas tshem tawm cov dej noo ntawm cov khoom los ntawm sublimation, ua rau cov khoom qhuav.Nws yog feem ntau siv nyob rau hauv ntau yam industries xws li kws tshuaj, khoom noj khoom haus ua thiab kev soj ntsuam kuaj.Lub hauv paus ntsiab lus ntawm cov cuab yeej zoo nkauj no yog nyob rau hauv lub peev xwm los khov ib yam khoom thiab tom qab ntawd siv lub tshuab nqus tsev kom tshem tawm cov dej khov molecules yam tsis tau yaj lawv ua kua.

Cov txheej txheem khov kom qhuav muaj peb theem tseem ceeb: khov, thawj ziab thiab theem nrab ziab.Thaum lub caij khov, cov khoom yog thawj zaug txias rau qhov kub thiab txias, feem ntau hauv qab nws qhov chaw khov.Qhov no yog ua tiav los ntawm kev muab cov khoom tso rau hauv lub freeze-drying chamber thiab siv lub tub yees system los tsim ib qho chaw tswj.Thaum cov khoom khov lawm, nws tuaj yeem txav mus rau qib tom ntej.

Kev ziab thawj zaug yog cov kauj ruam tseem ceeb hauv kev ziab kom qhuav.Qhov no yog cov txheej txheem ntawm sublimation, nyob rau hauv uas cov dej khov molecules mus ncaj qha los ntawm cov khoom hauv lub xeev mus rau lub xeev roj yam tsis tau dhau los ntawm cov kua theem.Qhov no yog ua tiav los ntawm kev siv lub tshuab nqus tsev rau lub freeze-drying chamber, txo qhov siab thiab evaporating cov dej molecules.Khaws qhov kub thiab txias thaum lub sij hawm kauj ruam no tiv thaiv cov khoom los ntawm kev puas tsuaj los yog deteriorating.

Cov kauj ruam kawg, kev ziab khaub ncaws thib ob, yog qhov tseem ceeb kom tshem tawm cov dej molecules uas tsis tau muab tshem tawm hauv thawj kauj ruam ziab.Nws yog ua tiav los ntawm me ntsis nce qhov kub thiab txias nyob rau hauv lub freeze dryer chamber, uas ua rau cov dej molecules ntxiv rau evaporate.Cov kauj ruam no ntxiv rau kev ruaj ntseg ntev thiab zoo ntawm cov khoom qhuav.

Lub hauv paus ntsiab lus ntawm kev ziab kom qhuav yog ua raws li lub tswv yim ntawm kev khaws cia cov qauv qub thiab cov khoom ntawm ib yam khoom.Tsis zoo li lwm txoj kev ziab khaub ncaws xws li cua ziab lossis tshuaj tsuag kom qhuav, khov ziab kom txo qis kev puas tsuaj los ntawm qhov kub thiab txias thiab hloov siab.Los ntawm khov cov khoom thiab tshem tawm cov dej los ntawm sublimation, kev ncaj ncees ntawm cov khoom raws li nws cov khoom noj muaj txiaj ntsig, tsw thiab aroma yog khaws cia.

Kev siv cov tshuab ziab khaub ncaws kom qhuav yog nthuav mus rau ntau yam kev lag luam.Hauv kev lag luam tshuaj, nws yog dav siv los khaws cov khoom siv roj ntsha, tshuaj tiv thaiv thiab tshuaj.Cov khoom khov-qhuav tuaj yeem yooj yim reconstituted nrog dej kom yooj yim cia, tsheb thauj mus los thiab siv tom ntej.

Hauv kev lag luam khoom noj khoom haus, khov-qhuav ua rau nws muaj peev xwm khaws cov khoom noj uas tsis zoo xws li txiv hmab txiv ntoo, zaub thiab txawm tias cov khoom siv mis nyuj.Cov txheej txheem khaws cia lub ntuj saj thiab kev ntxhib los mos ntawm cov khoom noj thaum ncua lawv lub neej txee.Tsis tas li ntawd, cov khoom noj khov-qhuav yog lub teeb yuag thiab compact, ua rau lawv nyiam cov neeg taug kev, cov chaw pw hav zoov, thiab cov neeg caij nkoj vim lawv tso cai rau dej yooj yim.

Hauv cov ntsiab lus, lub hauv paus ntsiab lus ntawm khov tshuab ziab khaub ncaws yog ua raws li cov txheej txheem ntawm sublimation, uas cov dej khov molecules tau hloov pauv ncaj qha los ntawm cov khoom mus rau cov roj hauv lub tshuab nqus tsev.Cov thev naus laus zis ua kom ntseeg tau tias cov qauv qub thiab cov khoom ntawm cov khoom raug khaws cia, ua rau nws muaj nuj nqis hauv kev lag luam xws li kws tshuaj thiab kev ua zaub mov.Lub peev xwm ntawm kev ziab kom qhuav los ua cov khoom qhuav nrog lub neej ntev ntawm cov txee thiab qhov lwj me me tau ua kom khov kom qhuav cov txheej txheem khaws cia thoob ntiaj teb.
