Nqus Freeze Drying Machine

Nqus Freeze Drying Machine

Tag nrho cov txheej txheem khov ziab ntawm cov zaub mov khov tshuab ziab khaub ncaws yog qhov hloov pauv ntawm cov cua sov thiab huab cua tshwm sim tib lub sijhawm. Tus nqi ntawm tshav kub & huab hwm coj transformation ob qho tib si cuam tshuam tus nqi ntawm khov kom qhuav. Txhua yam uas cuam tshuam rau kev hloov pauv ntawm tshav kub thiab huab hwm coj yuav cuam tshuam rau tus nqi ziab. Kuv yuav piav qhia txog cov laj thawj hauv ntu hauv qab no.

1.     Lub xeev ntawm raw khoom

Lub xeev ntawm cov khoom siv raw tuaj yeem sib txawv ua ob hom, uas yog kua thiab khoom sib npaug. Cov khoom hauv lub xeev thiab cov concentration ntawm cov kua muaj kev cuam tshuam loj heev ntawm cov txheej txheem ziab.

2.     Tus nqi ntawm pre-freezing

Lub crystallization thaum lub caij khov yuav cuam tshuam tus nqi ntawm qhov khov thiab qhov tawg ntawm cov khoom qhuav. Qhov sib txawv ntawm ceev khov thiab khov qeeb yog raws li hauv qab no: ceev khov ua rau cov dej khov me me, thaum qeeb khov ua rau cov dej khov loj dua. Cov dej khov loj loj yog qhov zoo rau sublimation, thaum cov dej khov me me tsis zoo rau sublimation. Kev khov sai sai ua rau qis sublimation tus nqi thiab ceev desorption tus nqi. Kev khov qeeb qeeb ua rau tus nqi sublimation ceev thiab qeeb qeeb.

3.     Qhov loj ntawm cov khoom siv raw

Thaum cov khoom khov-qhuav nyob rau hauv cov khoom noj khov-drying tshuab, muaj qee qhov sib piv ntawm thaj chaw rau cov khoom tuab tom qab nws muab faib rau hauv ntim, uas yog, khov-drying yog cuam tshuam nrog lub ntim ntim. Qhov chaw me me thiab tuab yog qhov zoo rau cov dej sublimation, yooj yim khov-drying thiab zoo zoo. Thaum ziab, ntub hnyav hnyav ntawm ziab ntawm chav tsev lub tais yog qhov tseem ceeb los txiav txim siab lub sij hawm ziab. Feem ntau, qhov thinner lub thickness ntawm cov khoom tsub zuj zuj, lub tshav kub thiab huab hwm coj hloov ceev ceev, thiab lub sij hawm qhuav qhuav. Txawm li cas los xij, cov ntaub ntawv nyias nyias ua rau cov khoom ziab qhuav tsawg dua ib pawg ntawm ib chav tsev khov-qhuav qhov chaw, uas tsis zoo rau kev ua kom cov zis ntau ntxiv rau ib cheeb tsam khov-qhuav thiab ib lub sijhawm.

4.     Siab nyob rau hauv qhuav chamber

Cov qib siab nyob rau hauv lub ziab chamber ntawm cov zaub mov lyophilizer cuam tshuam tus nqi ntawm tshav kub hloov thiab loj hloov. Rau kev hloov pauv huab hwm coj, qhov qis dua qhov siab, qhov zoo dua, thaum hloov cov cua sov, qhov siab dua, qhov zoo dua. Kev hloov pauv huab hwm coj feem ntau yog txiav txim siab los ntawm qhov kub thiab siab ntawm sublimation interface thiab cov txheej txheej qhuav. Txhawm rau ua kom cov dej vapor khiav tawm hauv cov txheej qhuav, ua ntej, qhov kub ntawm sublimation interface yuav tsum tau tsa kom nce cov dej vapor siab ntawm lub interface. Qhov thib ob yog los txhim kho lub tshuab nqus tsev kawm ntawv ntawm lub tshuab ziab khaub ncaws thiab txo cov chav siab ntawm qhov chaw ziab khaub ncaws.

5.     Thaum tshav kub kub hloov hom kub hloov hom

Raws li kev faib tawm ib txwm muaj tuaj yeem muab faib ua: conduction, convection, thermal tawg thiab nruab nrab cua sov. Txij li cov txheej txheem ntawm sublimation drying cuam tshuam nrog kev hloov pauv ntawm tshav kub thiab huab hwm coj (dej vapor), tus nqi ziab tau cuam tshuam zoo heev los ntawm cov txheej txheem hloov hluav taws xob tau txais los hloov cov cua sov kom zoo rau cov khoom siv.
