Tso lus
Kev ziab kom qhuav, lossis lyophilization, yog cov txheej txheem zoo siv los khaws cov ntaub ntawv los ntawm kev tshem cov dej los ntawm sublimation. Kev nkag siab tias lub tshuab ziab khaub ncaws txias txias npaum li cas yog qhov tseem ceeb rau kev txaus siab rau nws lub luag haujlwm hauv ntau daim ntawv thov, los ntawm kev khaws zaub mov mus rau cov tshuaj. Hauv qhov blog no, peb yuav tshawb xyuas qhov kub thiab txias ntawm lub tshuab ziab khaub ncaws, tshwj xeeb yog tsom rauMicro Freeze Dryer-a compact version ntawm cov khoom siv tsoos. Peb mam li delve rau hauv nws cov kev khiav hauj lwm kub, yam uas cuam tshuam rau cov kub no, thiab yuav ua li cas lawv cuam tshuam rau lub freeze-drying txheej txheem.
Lub hauv paus ntawm Freeze Drying thiab Temperature
Kev ziab kom qhuav yog txheej txheem peb-theem suav nrog kev khov, sublimation, thiab desorption. Txhua theem yuav tsum tau tswj qhov kub thiab txias kom ntseeg tau tias cov txiaj ntsig zoo. Nov yog cov lus piav qhia luv luv ntawm qhov kub thiab txias ua lub luag haujlwm tseem ceeb hauv kev ziab kom qhuav:
Txias theem
Thawj theem khov yog ua kom txias cov khoom mus rau qhov kub thiab txias uas tag nrho cov dej hauv nws solidifies rau hauv dej khov. Cov kauj ruam no yog qhov tseem ceeb vim tias nws teeb tsa theem rau kev ua haujlwm zoo sublimation. Feem ntau, qhov kub thiab txias yuav tsum qis txaus kom khov cov khoom tiav, uas feem ntau txhais tau tias ncav cuag qhov ntsuas kub qis li -40 degree rau -80 degree (-40 degree F mus rau -112 degree F).
Sublimation theem
Thaum lub sij hawm sublimation, qhov kub thiab siab yog ua tib zoo tswj kom cov dej khov hloov mus rau hauv vapor ncaj qha. Cov theem no yuav tsum tau tswj xyuas qhov kub thiab txias kom ntseeg tau tias cov khoom tseem khov thaum cov dej khov sublimates. Qhov ntsuas kub nyob rau theem no feem ntau khaws cia nyob ib puag ncig -30 degree rau -50 degree (-22 degree F txog -58 degree F), nyob ntawm seb qhov kev xav tau ntawm cov khoom siv. ua tiav.
Desorption theem
Qhov kawg theem, desorption, yuav tshem tawm cov dej noo ntxiv los ntawm kev siv cov cua sov ntxiv. Cov theem no xyuas kom meej tias cov khoom yog qhuav tag. Qhov kub ntawm lub sijhawm no tuaj yeem sib txawv tab sis feem ntau siab dua cov uas siv hauv sublimation, feem ntau yog li ntawm -20 degree rau -30 degree (-4 degree F txog -22 degree F) .
Micro Freeze Dryer: Kub Specifications
Lub tshuab ziab khaub ncaws me me yog ib qho me me, ntau dua ntawm cov tshuab ziab khaub ncaws. Txawm hais tias nws qhov loj me, nws ua haujlwm ntawm cov ntsiab lus zoo sib xws tab sis nrog cov ntsuas kub tshwj xeeb haum rau nws tus qauv tsim. Nkag siab txog nws qhov ntsuas kub yog qhov tseem ceeb rau kev siv nws kom zoo.
Tej yam kub thiab txias
Micro Freeze Dryers, zoo li lawv cov counterparts loj, yog tsim los kom ua tiav qhov kub qis heev kom khov cov khoom kom txaus. Nov yog ib qho kev piav qhia ntawm qhov ntsuas kub ib txwm rau cov tshuab ziab khaub ncaws me me:
