Pre-freezing Stage for Freeze Dry
Lub tshuab nqus tsev kom qhuav yog ib txoj kev ua kom qhuav qeeb uas ua ntej ua kom cov khoom muaj dej khov rau hauv dej khov thiab tom qab ntawd sublimates hauv lub tshuab nqus tsev kom tshem tawm cov dej. Yog li thawj kauj ruam hauv kev ziab yog kom khov cov khoom uas muaj cov dej noo ntau rau hauv cov khoom, txheej txheem hu ua pre-freezing stage.
Lub hom phiaj ntawm pre-freezing
Yog tias cov khoom tsis khov rau hauv cov khoom khov thiab nqus tau ncaj qha, thaum lub tshuab nqus tsev twj tso kua mis mus rau ib theem, cov cua yaj hauv dej yuav npuas zoo li dej "boiling", thiab cov khoom yuav tawm ntawm lub thawv mus rau sab nraud. thawv, mus rau qhov siab hauv qab 611 mbar, cov khoom khov rau hauv dej khov, tab sis tsis muaj cov duab ruaj khov, thiab cov thawv iav tawg. Qhov kev khov no yog tshwm sim los ntawm cov evaporation ntawm cov dej ntau kom nqus tau cov cua sov ntawm cov khoom nws tus kheej, thiab nws kuj yog qhov kev hloov ntawm lub cev lub cev los ntawm kev hloov ntawm lub siab, kuj hu ua lub tshuab nqus tsev tub yees.
Yog li ntawd, thawj lub hom phiaj ntawm pre-freezing yog kho cov khoom. Tsuas yog tom qab lub tshuab nqus tsev tom qab khov, cov khoom qhuav yuav muaj qhov ruaj khov.
Feem ntau ntawm cov khoom khov-qhuav yog cov kev daws teeb meem, qee qhov muaj ntau qhov sib xyaw ua ke, sib xyaw ntawm cov kev daws teeb meem thiab kev tshem tawm, thiab qee qhov kuj muaj cov tshuaj lom neeg lom neeg xws li cov protein thiab cov kab mob. Qee cov khoom lag luam yuav tsim cov pob hauv lub xeev thaum khov, thiab qee cov khoom yuav ua rau lub xeev iav. Tom qab cov khoom qhuav qhuav rau ib lub sijhawm, cov txheej txheej ziab khaub ncaws sab saud thiab qis qis yuav raug tsim. Thaum cov khoom nyob rau hauv khov txheej tseem qhuav, sublimated huab cua txaus yuav tsum dhau los ntawm txheej ziab. Yog tias cov khoom khov rau hauv lub xeev crystalline, muaj qhov sib txawv ntawm cov muaju. Lub sublimation airflow tuaj yeem hla tau zoo yam tsis muaj kev cuam tshuam rau kev ziab ntawm cov khoom. Yog tias cov khoom khov rau hauv lub khob iav, vim tias lub iav lub xeev yuav luag tsis muaj qhov khoob thiab tsis muaj cov channel rau sublimation airflow, txuas ntxiv ziab ntawm cov khoom yuav raug cuam tshuam thiab ziab yuav ua tsis tiav.
Yog li ntawd, yog tias cov khoom khov rau hauv lub khob iav, nws yog ib qho tsim nyog yuav tsum tau sim hloov lub khob iav mus rau hauv lub xeev crystalline, uas yog qhov zoo rau sublimation.
Cov khoom khov yog rhuab mus rau saum cov iav hloov pauv kub thiab qis dua qhov kub ntawm qhov melting, thiab khaws cia ntawm qhov kub no rau ob peb teev. Raws li cov khoom lag luam txuas ntxiv mus rau qhov ntsuas kub no, lub iav lub xeev yuav maj mam hloov mus rau hauv lub xeev crystalline, thiab tom qab ntawd cov khoom tau txias dua thiab txias. Txias kiag li. Lub xeev iav tuaj yeem hloov mus rau hauv lub xeev crystalline los ntawm cov txheej txheem reheating no. Yog li ntawd, lub hom phiaj thib ob ntawm pre-freezing yog tsim cov muaju uas zoo rau sublimation.
Cov khoom qhuav yuav tsum muaj cov qauv sib xws thiab cov xim zoo ib yam. Yog tias lawv tsis khov zoo, qee cov khoom yuav ntxhib, qee cov khoom yuav zoo, qee cov khoom yuav muaj xim tib yam, thiab qee cov khoom yuav muaj cov qauv nrog cov xim sib txawv. Feem ntau, tag nrho cov khoom yuav tsum tau khov rau ib qho kev ntsuas kub, feem ntau yog 5 degree, thiab khaws cia ntawm qhov kub thiab txias rau lub sijhawm kom ntseeg tau tias tag nrho cov khoom ncav cuag qhov kub thiab txias thiab tom qab ntawd txias ua ke, kom cov txheej txheem khov ntawm tag nrho cov khoom. yog tib yam nkaus. Lub hom phiaj thib peb ntawm pre-freezing yog li ntawd los xyuas kom meej tias tag nrho cov khoom tau txais tib lub microstructure.
Lub ntsiab lus eutectic ntawm cov khoom tau hais ua ntej, uas yog qhov kub thiab txias ntawm cov khoom, yog li cov khoom ua ntej khov yuav tsum qis dua qhov ntsuas kub ntawm eutectic ntawm cov khoom kom cov khoom yuav tsis npuas thaum sublimated nyob rau hauv lub tshuab nqus tsev. Ua ntej khov yuav tsum yog tsawg kawg yog 5 degree qis dua qhov kub ntawm eutectic ntawm cov khoom.
