Tshuaj yej Powder Freeze-drying Machine
Tshuaj yej hmoov freeze-drying tshuab
Lub hauv paus ntsiab lus ntawm khov-drying instant tshuaj yej hmoov yog: ua ntej, cov tshuaj yej concentrated uas yuav tsum tau qhuav yog kiag li khov nyob rau hauv qis kub, thiab ces cov dej khov siv lead ua (dej) yog ncaj qha tshem tawm los ntawm sublimation nyob rau hauv lub siab nqus tsev vacuum, thiaj li yuav tau txais. freeze-dried tshuaj yej hmoov.
Vim tias tag nrho cov txheej txheem ziab kom tiav nyob rau hauv cov xwm txheej ntawm lub tshuab nqus tsev thiab qhov kub thiab txias, tsis txhob cuam tshuam oxidation thiab kub siab ntawm cov khoom siv roj ntsha, cov tshuaj lom neeg lom neeg hauv cov tshuaj yej hmoov yog khaws cia rau qhov siab tshaj plaws, thiab cov tshuaj yej qhuav hmoov. yog porous spongy qauv, yooj yim soluble hauv dej, thiab tuaj yeem rov qab tau sai. Cov kev xav tau zoo ntawm khov-dried instant tshuaj yej yog raws li hauv qab no: kev ua haujlwm lom neeg tsis hloov pauv, cov xim zoo ib yam thiab lustre, tag nrho cov duab, cov qauv ruaj khov, nrawm nrawm thiab tsis tshua muaj dej noo.
1. Kev kho mob ua ntej
Pretreatment mas muaj xws li extraction, purification, concentration thiab lwm yam txheej txheem, lub hom phiaj ntawm uas yog rho tawm lub active Cheebtsam ntawm tshuaj yej nplooj thiab mloog zoo rau lawv mus rau ib tug tej yam ntim tom qab purification, thiaj li yuav txo tau lub workload nyob rau hauv lub freeze-drying thiab txuag. zog. Cov txiaj ntsig ntawm pretreatment muaj kev txiav txim siab ntawm cov xim thiab saj ntawm khov-dried instant tshuaj yej, yog li txaus mloog yuav tsum tau them rau pretreatment.
2. Prefreeze
Cov tshuaj yej cov kua zaub ua ntej ua ntej khov yog cov tshuaj aqueous uas muaj tshuaj yej polyphenols thiab lawv cov polymer sib xyaw. Nws qhov hnyav molecular li ntawm ntau pua txog kaum txhiab. Nws solubility sib txawv heev nrog rau qhov kub thiab txias, thiab nws yog ib qho yooj yim rau tsim tom qab txias av nkos. Cov tshuaj muaj qhov muaj zog viscosity thiab tuaj yeem ua raws li Teflon coated lyophilized tais thiab nyuaj rau tawg. Cov cuab yeej no yuav tsum tau coj mus rau hauv tus account thaum prefreezing.
Nws tuaj yeem txhim kho tus nqi khov-qhuav, thiab qhov sib txawv ntawm cov dej khov zoo tom qab sublimation yog me me, kom cov sublimation ntawm cov txheej hauv qab yog thaiv. Cov khoom lag luam sai-freezing tiav muaj cov khoom zoo, cov tsos zoo ib yam, thaj chaw loj tshwj xeeb, cov qauv ntxeem tau zoo thiab nrawm nrawm, tab sis qhov nqus dej ntawm cov khoom tiav yog qhov muaj zog.
Muaj ob lub ntsiab pre-freezing txoj kev ntawm concentrated tshuaj yej kua zaub. Ib qho yog muab tso rau ntawm lub phaj ua ntej, thiab tom qab ntawd kom txias thiab khov rau hauv qhov ceev-khov cia. Lwm qhov yog siv lub tshuab khov nab kuab sai hauv cov khoom me me (txhua batch yog kwv yees li 1 ~ 2kg) ua kom cov dej khov nyias nyias txog -30 degree, thiab tom qab ntawd txhuam rau hauv cov dej khov tawg thiab kis cov tais diav. Muaj cov khoom siv khov kho granulation txawv teb chaws, nyob rau hauv cov txheej txheem ntawm cov tshuaj tsuag tshuab cua txias, ncaj qha khov cov pos huab, nws qhov kom zoo dua yog qhov loj me me.
3. Cov xwm txheej thiab ceev ntawm sublimation
Nyob rau hauv cov txheej txheem khov-drying ntawm instant tshuaj yej, qhov kub ntawm cov khoom thiab cov cuab yeej txias yog feem ntau yog -25 degree thiab -30 degree, thiab saturated vapor siab ntawm cov dej khov ntawm qhov kub ntawm no yog 64 Pa thiab 38pa, ua. Yog li ntawd, ib qho kev sib txawv siab yog tsim ntawm sublimation nto thiab condensation nto, uas tuaj yeem muab piv rau lub zog sublimation. Nws yuav txhawb nqa sublimation ntawm cov khoom siv dej vapor, nrog rau qee qhov kev ntws mus txog qhov chaw txias txias, yog li condensing rau hauv Frost. Qhov kub ntawm condensation ntawm dej khov yog li 2.812kJ / g. Yog tias tsis muaj cua sov nkag thaum lub sij hawm sublimation txheej txheem, cov khoom yuav tsum tau txo lub zog sab hauv kom tau txais cov cua sov ntawm condensation kom txog rau thaum qhov kub thiab txias yog sib npaug nrog lub txias ntxiab kub, thiab sublimation nres. Yuav kom tswj tau qhov kub ntawm qhov sib txawv ntawm sublimation nto thiab qhov chaw txias, qhov kub txaus yuav tsum tau muab rau cov khoom.
