Peb yuav zam dhau qee qhov teeb meem cuam tshuam nrog cov qauv lyophilized ntawm lyophilizer. Peb yuav tham txog lawv los ntawm ntau qhov tshwm sim:
1, Tom qab khov-ziab stratification, txheej qis qis dua
Phenomenon: tom qab khov-ziab stratification, txheej qis qis dua lossis tag nrho cov khoom shrinks. Qee cov khoom tau khov zoo, thiab qee qhov poob rau hauv ob peb lub raj mis yuav luag tas.
Kev tsom xam: tsis ua ntej khov, sublimation nrawm dhau. Tej zaum nws yuav yog qhov ntsuas kub hauv cheeb tsam lossis siab ntawm lyophilizer siab dhau, ua rau lub zos yaj.
1. Yog tias cov tshuaj daws me me, cov teeb meem zoo li yuav tshwm sim ntau dua.
2. Txawm hais tias cov roj hmab ntsaws ntawm cov khoom ua kom qis tau kaw zoo. Ntawm qhov tsis sib xws, yog tias cov khoom lag luam yooj yim nqus dej noo, qhov tshwm sim no tseem yuav tshwm sim.
Cov ntaub ntawv nyob rau sab qis tsis qhuav tag, thiab cov dej khov hauv cov khoom txhawb nqa fuse thiab sib tsoo tom qab raug tshem tawm ntawm lub tsev rau khoom; Cov khoom siv tau rhaub nrawm heev thiab ntxov dhau tom qab nkag mus rau hauv lub tsev rau khoom, cov ntsiab lus eutectic ntawm cov khoom siv tsis tau mus txog, thiab txheej hauv qab ntawm cov khoom siv tau rhaub.
Qhov kub nce sai heev, thiab cov dej tsis tawm, ua rau qis dua kom yaj.
Cov iav hloov pauv kub ntawm cov tshuaj yog tsawg.
Cov thev naus laus zis khov siv los ntawm lub tshuab ziab khaub ncaws khov yuav siv sijhawm qee lub sijhawm. Thaum lub sijhawm khov no, qee cov tshuaj yaj me ntsis ua rau crystallize thiab nag hauv cov txheej txheej qis, ua rau muaj txiaj ntsig sib txawv ntawm txheej txheej sab saud thiab txheej qis dua tom qab cov khoom khov. Hauv qhov no, qhov kub sublimation tuaj yeem txo qis ib zaug thiab lub sijhawm sublimation tuaj yeem txuas ntxiv mus.
2, Khov qhuav qhuav tev
Phenomenon: thaum nqus tsev, muaj ntau cov npuas me me rau saum npoo, thiab ib txheej ntawm cov nplaim tau sib cais tom qab khov kom qhuav.
Kev tshuaj xyuas: cov khoom siv tau ib nrab thaws ua ntej lub tshuab nqus tsev ntawm cov lyophilizer ua tau raws li qhov xav tau. Ua ntej khov tsis zoo, dej tsis khov tag nrho, thiab cov dej ntws los ua cov npuas thaum lub tshuab nqus tsev.
Qhov tshwm sim no feem ntau tshwm sim los ntawm kev tsiv teb tsaws ntsev mus rau saum cov khov khov qhuav. Ua ntej khov tuaj yeem ua kom muaj zog.
Txog qhov kev hloov pauv ntawm lub thawv rau pem hauv ntej thaum lub hauv paus qhuav, vim hais tias lub tshuab nqus tsev cuam tshuam rau kev nrawm nrawm, koj tuaj yeem tshawb xyuas thawj zaug cov ntaub ntawv khov-ziab kom pom seb puas muaj qhov txawv txav hauv lub siab ntawm lub npov pem hauv ntej thiab cov khoom kub. Ib qho ntxiv, koj tuaj yeem lees paub txoj haujlwm ntawm cov fwj fwj. Cov fwj nyob ib ncig ntawm lub phaj yuav sublimate sai dua cov fwj nyob hauv nruab nrab.
Tsis muaj qhov sib txawv ntawm qhov kev hloov pauv ntawm lub tshuab nqus tsev ua ntej thiab tom qab sib piv.
Kev tswj lub tshuab nqus tsev feem ntau yog los ntawm cov khoom siv cua sov. Kev ua tau zoo ntawm lub tshuab nqus tsev, kev huv ntawm cov roj thiab qhov kub ntawm cov ntxiab dej yog qhov tseem ceeb.
Ib qho ntxiv, kev tshem tawm yuav tshwm sim tom qab lub sijhawm ntev. Nws yog ib txwm tswj hwm lub sijhawm khov kom qhuav. Piv txwv li, qhov sib txawv ntawm qhov nruab nrab nruab nrab ntawm phaj phaj thiab ntug ntawm cov khoom yog 4-7 degrees (ntau qhov khov khov kom qhuav). Thaum khov-ziab, lub sijhawm khov-ziab ib zaug yuav tsum ntev dua.
