Aug 23, 2024
Tso lus
Kev ziab kom qhuav, txwv tsis pub hu ua lyophilization, yog ib qho kev sib cuam tshuam uas tau hloov kho kev txuag zaub mov, tsim tshuaj, thiab tshawb nrhiav kev xav. Raws li ntau tus neeg xav txog cov cuab yeej no, lawv ib txwm muaj lus nug txog nws ua haujlwm li cas hauv. Kev siv cov kua nitrogen hauv cov tshuab ziab khaub ncaws yog ib qho kev txhawj xeeb heev. Hauv qhov kev pabcuam tag nrho, peb yuav tshawb xyuas qhov taw qhia saum toj mus rau hauv qab, nrog rau qhov tshwj xeeb tsom rauportable freeze dryersthiab lawv txoj haujlwm.
Nkag siab txog Kev Ua Kom Qhuav Qhuav
Ua ntej peb dhia mus rau hauv txoj haujlwm ntawm cov kua nitrogen hauv khov kom qhuav, kev nkag siab txog cov txheej txheem ntawm cov txheej txheem yog qhov tseem ceeb. Muaj peb theem tseem ceeb kom khov kom qhuav:
khov:
Cov khoom yog khov khov, ib txwm nyob ntawm qhov kub thiab txias hauv qab - 40 degree (- 40 degree F).
Qhov tseem ceeb kom qhuav (Sublimation):
Qhov nro yog txo qis, thiab kev siv zog yog siv los tso cai rau cov dej khov hauv cov khoom kom sublimate ncaj nraim los ntawm cov dej khov rau fume.
Kev xaiv kom qhuav (Desorption):
Ib qho dej uas tshuav tshuav raug tshem tawm los ntawm kev nce qhov kub ntxiv.
programming qhia
Lub voj voog no coj txog ib yam khoom uas ua raws li nws cov qauv tsim tshwj xeeb thiab tuaj yeem rov ua dej kom zoo.
Lub luag haujlwm ntawm Liquid Nitrogen hauv Kev Kho Kom Qhuav Qhuav
Tsis zoo li kev ntseeg nrov, feem ntau cov tshuab ziab khaub ncaws khov, nrog rau cov tshuab ziab khaub ncaws, tsis txhob siv cov kua nitrogen hauv lawv cov haujlwm tseem ceeb. Hloov chaw, lawv cia siab rau lub tshuab tub yees zoo ib yam li cov uas muaj nyob hauv cov tub yees hauv tsev, tab sis muaj peev xwm ncav cuag qhov kub qis dua.
Cov tshuab no feem ntau siv compressors thiab cov tub yees kom ua tiav qhov ntsuas kub qis qis uas yuav tsum tau ua kom khov kom qhuav. Cov txheej txheem cua txias feem ntau yog ua tiav los ntawm cascade tub yees los yog ib-theem system nrog cov tub yees zoo heev.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum cov kua nitrogen tsis feem ntau siv rau hauv cov txheej txheem khov kom qhuav, nws tuaj yeem ua lub luag haujlwm hauv qee qhov kev thov kom qhuav qhuav:
Pre-freezing:Qee lub chaw soj nstuam siv cov kua nitrogen sai sai ua ntej khov ua ntej muab tso rau hauv lub tshuab ziab khaub ncaws. Qhov no tuaj yeem muaj txiaj ntsig zoo rau qee cov ntaub ntawv rhiab heev.
Txias ntxiab:Hauv qee qhov high-end lossis industrial freeze dryers, kua nitrogen yuav siv tau rau hauv cov cuab yeej txias kom ntes dej vapor zoo dua.
Cov ntawv thov tshawb fawb:Qee qhov kev tshawb fawb tshwj xeeb khov tshuab ziab khaub ncaws tuaj yeem sib xyaw ua kua nitrogen rau kev sim teeb tsa tshwj xeeb.
Rau cov neeg siv nruab nrab ntawm lub tshuab ziab khaub ncaws yooj yim, txawm li cas los xij, kua nitrogen tsis yog ib feem ntawm qhov sib npaug.
Portable Freeze Dryers: Lawv ua haujlwm li cas
Portable freeze dryers tau txais koob meej nyob rau hauv xyoo tas los no, muab cov txiaj ntsig ntawm cov tshuab ziab khaub ncaws khov rau hauv pob ntau dua thiab siv tau zoo. Cov chav no yog tsim los rau kev siv hauv tsev, kev lag luam me, lossis kev tshawb fawb hauv cheeb tsam, thiab lawv ua haujlwm ntawm cov hauv paus ntsiab lus zoo ib yam li lawv cov khoom loj.
