Lub tshuab nqus tsev vacuum freeze dryer siv lub hauv paus ntsiab lus sublimation kom khov cov dej uas muaj cov khoom noj khoom haus rau hauv lub xeev ntawm qhov kub thiab txias, thiab tom qab ntawd hauv lub tshuab nqus tsev, ua kom cov dej hauv lawv sublimate ncaj qha los ntawm cov khoom hauv lub xeev mus rau lub xeev gaseous yam tsis muaj kua, tshem tawm. dej thiab khaws cov khoom noj. Kev ua haujlwm tag nrho ntawm lub tshuab ziab khaub ncaws yog cov txheej txheem ua kua → khoom → roj.
Lub tshuab nqus tsev vacuum freeze dryer yog dav siv nyob rau hauv freeze-drying processing ntawm ntau yam khoom noj. Nws yog siv los ntawm cov lag luam loj rau khov-qhuav ntawm txiv hmab txiv ntoo thiab zaub, nqaij, kas fes, probiotics, edible fungi, tshuaj suav tshuaj thiab tsiaj noj. Vim tias nws cov txiaj ntsig zoo tshaj plaws, lub tshuab ziab khaub ncaws rau cov khoom noj khov-qhuav yog raws li hauv qab no:
1) Thaum qhuav ntawm qhov kub thiab txias, cov khoom cua sov hauv cov khoom, xws li cov protein, vitamins, kab mob thiab lwm yam khoom siv bioactive, muaj kev tiv thaiv tag nrho.
2) Thaum qhuav ntawm qhov kub thiab txias, cov khoom tsis hloov pauv hauv cov khoom noj tau poob qis dua.
3) Kev ziab ntawm qhov kub tsis tshua muaj qhov tseem ceeb txwv kev loj hlob ntawm cov kab mob thiab kev ua haujlwm ntawm cov enzymes, thiab cov zaub mov zoo tswj nws cov khoom qub.
4) Kev ziab yog nqa tawm hauv lub xeev tsis muaj oxygen ntawm lub tshuab nqus tsev, thiab kev puas tsuaj ntawm qee qhov yooj yim oxidized Cheebtsam hauv cov zaub mov raug txo.
5) Tom qab lub tshuab nqus tsev khov-qhuav, cov zaub mov tsis muaj additives thiab cov as-ham hauv qab yog khaws cia.
6) Tom qab lub tshuab nqus tsev kub qis kom qhuav, qhov ntim ntawm cov zaub mov tseem tsis hloov pauv, nyob rau hauv daim ntawv ntawm daim txhuam cev xoob thiab ntxeem tau, nrog cov dej muaj zog.
7) Thaum lub sij hawm khov-drying txheej txheem, 95% ~ 99% dej raug tshem tawm, thiab cov khoom noj khoom haus qhuav qhuav tuaj yeem khaws cia rau hauv chav sov kom ntev.
8) Cov khoom noj khoom haus tshem tawm noo noo yog lub teeb hauv qhov hnyav thiab yooj yim nqa thiab thauj.
Lub tshuab nqus tsev vacuum freeze drier muaj qhov zoo ntawm kev ziab khaub ncaws, microwave kom qhuav, tsis kub frying thiab tshuaj tsuag kom qhuav. Yog li ntawd, cov tuam txhab ua zaub mov siv cov tshuab ziab kom qhuav los tsim cov khoom noj sib sib zog nqus, kom cov neeg siv khoom txaus siab rau cov khoom noj muaj txiaj ntsig thiab noj qab nyob zoo.
