Umshini wokomisa oqandisiwe (i-lyophilizer) ubuchwepheshe obusebenzisa isimiso se-sublimation ukuze komiswe. Le nqubo ihilela ukuqandisa ngokushesha into ukuze yomiswe emazingeni okushisa aphansi, bese kuthi, ngaphansi kwendawo efanele ye-vacuum, okubangela ukuthi ama-molecule amanzi aqandisiwe angene ngqo emhwameni wamanzi bese ephuma. Umkhiqizo otholakala ngokuqandisa ubizwa ngokuthi i-lyophilizate, Le nqubo ibizwa ngokuthi i-lyophilization.
Ngaphambi kokomiswa, into ihlala emazingeni okushisa aphansi (isimo esiqandisiwe), kanti amakristalu eqhwa asatshalaliswa ngokulinganayo ngaphakathi kwento. Ngesikhathi sokufakwa kwe-sublimation, akukho ukugcwala okwenzekayo ngenxa yokuphelelwa amanzi emzimbeni, ngaleyo ndlela kugwenywe imiphumela emibi efana nokugqwala noma ukubola okubangelwa umhwamuko wamanzi. Izinto ezomisiwe zibonakala njengesiponji esomile, esinezimbobo, ngokuyisisekelo kungekho shintsho kuvolumu, futhi zincibilika kakhulu emanzini, zibuyela kalula esimweni sazo sokuqala. Le nqubo ivimbela kakhulu ukubola kwezinto ezomisiwe ngokomzimba, ngamakhemikhali, kanye nangokwebhayoloji.
Isomisi sokuqandisa siqukethe uhlelo lokuqandisa, uhlelo lokuvasa, uhlelo lokufudumeza, kanye nohlelo lokulawula izinsimbi zikagesi. Izingxenye zalo eziyinhloko zifaka phakathi igumbi lokomisa, i-condenser, iyunithi yokuqandisa, iphampu yokuvasa, kanye nedivayisi yokufudumeza/yokupholisa. Umgomo osebenzayo wokomisa ukuqandisa kuqala izinto ukuze zome ngaphansi kwezinga lokushisa lazo eliphindwe kathathu, bese kuthi, ngaphansi kwezimo ze-vacuum, kubangele ukuthi amanzi aqinile (iqhwa) ezintweni angene ngqo emhwameni wamanzi, osuswa ezintweni, ngaleyo ndlela womise. Ngemva kokwelashwa kwangaphambili, izinto zithunyelwa ekamelweni lokuqandisa ngokushesha ukuze ziqandiswe, bese kuba ekamelweni lokomisa ukuze kuncishiswe amanzi emzimbeni, bese ekugcineni zipakishwe endaweni yokusebenzela ngemva kokucubungula. Uhlelo lokuvasa lusungula indawo enengcindezi ephansi ekamelweni lokomisa le-sublimation, uhlelo lokufudumeza luhlinzeka ngokushisa okufihliwe kwe-sublimation ezintweni, kanti uhlelo lokuqandisa lunikeza amandla okupholisa adingekayo ku-cold trap kanye negumbi lokomisa.
Lo mshini usebenzisa ukushisa kwemisebe, ukuqinisekisa ukusatshalaliswa kokushisa okufanayo ezintweni; usebenzisa isicupho esibandayo sokubamba amanzi esivumela ukuncibilika okusheshayo; usebenzisa iyunithi yepompo ye-vacuum enekhono lokuhlukanisa amanzi namafutha; usebenzisa uhlelo lokuqandisa oluphakathi oluhambisanayo oluhlinzeka ngokupholisa uma kudingeka kumasekethe amaningi, okuqinisekisa izimo zokusebenza ezizinzile kanye nokusebenza kahle kwamandla; unikeza ukulawula kobuhlakani bokwenziwa, okunikeza ukunemba okuphezulu kokulawula kanye nokusebenza okulula.
Izidingo zekhwalithi zemikhiqizo eyomiswe ngokuqandisa yilezi: umsebenzi webhayoloji ongashintshi, ukubukeka nombala ofanayo, isimo somzimba esiqinile, isakhiwo esiqinile, izinga lokuncibilika okusheshayo, kanye nomswakama ophansi osele. Ukuze uthole imikhiqizo esezingeni eliphezulu, ukuqonda okuphelele kwethiyori yokomisa ngokuqandisa kanye nezinqubo kubalulekile. Inqubo yokomisa ngokuqandisa ihlanganisa izigaba ezintathu: ukuqandisa ngaphambi kokuqandisa, ukomisa okuyinhloko (i-sublimation), kanye nokomisa kwesibili (ukususwa). Ukunciphisa umjikelezo wokuqandisa ngokunengqondo nangokuphumelelayo kunokubaluleka okukhulu kwezomnotho ekukhiqizweni kwezimboni.
"Uma unesithakazelo komiswe ngokuqandisa noma ungathanda ukufunda kabanzi ngemikhiqizo nezinsizakalo zethu, sicela ukhululeke uku-Xhumana nathi. Siyajabula ukukunikeza iseluleko nokuphendula noma yimiphi imibuzo ongase ube nayo. Ithimba lethu lilangazelela ukukukhonza nokusebenzisana nawe esikhathini esizayo!
