Daim Ntawv Thov thiab Lub Luag Haujlwm ntawm Cov Twj Tso Kua Mis Hauv Cov Tshuab Ziab Khaub Ncaws

Ua ib feem tseem ceeb ntawm lub tshuab ziab khov, lub twj tso kua mis ua lub luag haujlwm tseem ceeb hauv cov txheej txheem ziab khov. Lub tshuab ziab khov (lyophilizer) yog ib qho khoom siv dav dav hauv kev lag luam khoom noj, tshuaj, thiab tshuaj lom neeg. Los ntawm kev khov thiab sublimating cov khoom hauv qab qhov kub qis thiab qhov siab qis, nws ua tiav lub xeev anhydrous lossis qis noo noo, yog li ua kom lub txee ntev ntawm cov khoom thiab txhim kho nws qhov ruaj khov.

Lub Luag Haujlwm Tseem Ceeb ntawm Lub Twj Tso Kua Mis

Lub luag haujlwm tseem ceeb ntawm lub twj tso kua mis nqus tsev hauv lub tshuab ziab khov yog los tsim thiab tswj kom muaj qhov chaw nqus tsev, uas yog qhov tseem ceeb rau cov txheej txheem ziab khov. Lub twj tso kua mis nqus tsev txuas ntxiv tshem tawm cov pa roj tawm ntawm lub cev, maj mam txo qhov siab sab hauv. Thaum qhov siab poob qis mus rau ib qib, cov dej noo hauv cov khoom pib hloov ncaj qha los ntawm cov khoom khov mus rau cov pa roj - ib qho txheej txheem hu ua sublimation - yog li ua tiav kev ziab khov ntawm cov khoom.

Tshwj xeeb, daim ntawv thov thiab lub luag haujlwm ntawm lub twj tso kua mis hauv lub tshuab ziab khov tau pom tseeb hauv cov hauv qab no:

Tsim ib qho chaw nqus tsev:Lub twj tso kua mis nqus tsev yuav tshem tawm cua ntawm lub chamber ziab, txo qhov siab sab hauv thiab tsim kom muaj qhov chaw nqus tsev. Qhov chaw no tso cai rau cov dej khov hauv cov khoom kom sublimate ncaj qha mus rau hauv cov dej pa hauv qab qhov siab qis, zam cov txheej txheem ntawm cov dej khov yaj mus ua kua thiab tom qab ntawd evaporated, yog li txhim kho kev ziab zoo.

Kev tswj siab:Thaum lub sijhawm ziab khov, lub twj tso kua mis nqus tsev tuaj yeem kho thiab tswj qhov siab hauv chav ziab kom haum. Qhov no yog qhov tseem ceeb rau kev ua kom lub tshuab sublimation zoo, vim tias cov ntaub ntawv thiab cov khoom sib txawv muaj cov nqi sublimation sib txawv nyob rau hauv qhov siab sib txawv.

Txhim kho kev ua haujlwm zoo thiab cov khoom zoo:Cov khoom siv twj tso kua mis ua haujlwm tau zoo tuaj yeem ncav cuag qib nqus tsev uas xav tau sai sai, ua kom lub sijhawm ziab khov luv dua, thiab ua kom cov khoom tsim tau zoo dua. Tib lub sijhawm, nws tiv thaiv cov khoom zoo los ntawm kev txo cov khoom seem. Qhov no tseem ceeb heev rau cov tuam txhab tsim cov khoom ziab khov, vim nws cuam tshuam ncaj qha rau kev sib tw ntawm cov khoom lag luam hauv kev ua lag luam.

Txuag cov nqi zog:Lub twj nqus tsev zoo tuaj yeem ua tiav qib nqus tsev uas xav tau hauv lub sijhawm luv dua, yog li txo kev siv hluav taws xob. Rau cov tshuab ziab khov uas khiav tas li, qhov no txhais tau tias yuav txuag hluav taws xob ntau.

Hom thiab Kev Xaiv Cov Twj Tso Kua Mis

Cov hom twj nqus tsev uas siv rau hauv cov tshuab ziab khov muaj xws li cov twj nqus tsev rotary vane, cov twj nqus tsev centrifugal, thiab cov twj turbomolecular. Txhua hom muaj nws cov txiaj ntsig thiab cov xwm txheej siv tau:

Lub twj tso kua mis rotary vane:Lub twj tso kua mis no paub txog nws qhov me me, lub teeb yuag, cov qauv yooj yim, thiab yooj yim txij nkawm, yog li nws siv dav hauv cov ntawv thov uas xav tau lub tshuab nqus tsev siab lossis lub tshuab nqus tsev ceev. Nws rho cov pa roj los ntawm lub tshuab tig thiab tuaj yeem ua tiav lub tshuab nqus tsev siab hauv lub sijhawm luv luv, ua kom cov dej noo sai dua.

Lub twj tso kua mis centrifugal:Nws muaj qhov nrawm nrawm, nqus tsev, thiab muaj roj ntau, hom no haum rau cov tshuab nqus tsev loj. Nws siv lub zog centrifugal uas tsim los ntawm kev tig ceev ceev los rho tawm roj, ua tau raws li qhov xav tau ntawm kev tsim khoom ntau.

Lub twj tso kua dej turbomolecular:Lub twj tso kua turbomolecular no muaj kev khiav ceev heev, nqus tsev siab heev, me me, thiab siv hluav taws xob tsawg, yog li nws zoo tagnrho rau cov tshuab nqus tsev uas raug. Nws rho cov roj tawm ntawm lub turbine uas tig ceev heev thiab muaj peev xwm muab lub zog siab qis heev, ua tau raws li qhov yuav tsum tau ua rau kev npaj cov ntaub ntawv huv siab.

Thaum xaiv lub twj tso kua mis nqus tsev, yuav tsum xav txog tej yam xws li qhov ceev ntawm lub twj tso kua mis, qhov siab ua haujlwm, qhov huv ntawm qhov chaw ua haujlwm, thiab tus nqi kho. Tib lub sijhawm, txhawm rau kom lub tshuab ziab khov ua haujlwm tau zoo li qub thiab txuas nws lub neej kev pabcuam ntev, yuav tsum tau saib xyuas lub twj tso kua mis nqus tsev tas li - suav nrog kev kuaj xyuas cov foob, lub peev xwm nqus, thiab hloov roj ntawm lub twj tso kua mis nqus tsev.

Xaus lus

Ua ib feem tseem ceeb ntawm lub tshuab ziab khov, qhov kev ua haujlwm ntawm lub twj tso kua mis nqus tsev cuam tshuam ncaj qha rau qhov ua haujlwm zoo thiab kev nyab xeeb ntawm cov khoom siv. Los ntawm kev tsim thiab tswj hwm ib puag ncig nqus tsev, lub twj tso kua mis nqus tsev tsis yog tsuas yog txhim kho qhov ua haujlwm zoo ntawm cov txheej txheem ziab khov thiab qhov zoo ntawm cov khoom, tab sis kuj pab cov tuam txhab txuag cov nqi hluav taws xob. Yog li ntawd, thaum xaiv lub twj tso kua mis nqus tsev, nws yog ib qho tsim nyog los xav txog ntau yam raws li qhov xav tau tiag tiag, xyuas kom meej tias xaiv cov khoom siv twj tso kua mis nqus tsev zoo, thiab ua kev saib xyuas tsis tu ncua kom lav qhov ua haujlwm ib txwm ntawm lub tshuab ziab khov thiab txuas ntxiv nws lub neej kev pabcuam.
