A Isomisi Esiqandisiwe(i-lyophilizer) isebenzisa isimiso sokufaka izinto eziqinile ekomeni. Le nqubo ihilela ukuqandisa ngokushesha izinto emazingeni okushisa aphansi, bese kuthi, ngaphansi kwendawo efanelekile yokungafaki i-vacuum, okuvumela ama-molecule amanzi aqandisiwe ukuba angene ngqo emfuleni wamanzi futhi aphume. Umkhiqizo otholakala ngokuqandisa ubizwa ngokuthi i-lyophilizate (noma umkhiqizo oqiniswe nge-lyophilized), futhi le nqubo yaziwa ngokuthi i-lyophilization.
Ngaphambi kokoma, izinto zihlala emazingeni okushisa aphansi (zisesimweni seqhwa), kanti amakristalu eqhwa asatshalaliswa ngokulinganayo ngaphakathi kwawo. 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 zithatha isakhiwo esomile, esinezimbobo, esifana nesiponji ngaphandle kokushintsha kwevolumu, futhi ziyancibilika kalula emanzini ukuze zibuyisele isimo sazo sokuqala. Le nqubo ivimbela kakhulu ukuwohloka kwezinto ezibonakalayo kanye nezamakhemikhali.
Isomisi esiqandisayo siqukethe uhlelo lokuqandisa, uhlelo lwe-vacuum, uhlelo lokufudumeza, kanye nohlelo lokulawula izinsimbi zikagesi. Izingxenye zalo eziyinhloko zifaka phakathi igumbi lokomisa, i-condenser (i-cold trap), iyunithi yokuqandisa, iphampu ye-vacuum, kanye namadivayisi okushisa/okupholisa. Umgomo osebenzayo wesomisi esiqandisayo ukuqala ngokuqandisa izinto ukuze zomiswe zibe ngaphansi kwephuzu lazo eliphindwe kathathu, bese, ngaphansi kwezimo ze-vacuum, uvumela amanzi aqinile (iqhwa) ezintweni ukuthi angene ngqo emhwameni wamanzi bese esuswa, ngaleyo ndlela omise izinto. Ngemva kokwelashwa kwangaphambili, izinto zithunyelwa endaweni yokugcina izinto eziqandisayo ngokushesha ukuze ziqandiswe, bese zidluliselwa endaweni yokugcina izinto ezomisa ukuze ziphelelwe amanzi emzimbeni, bese ekugcineni zipakishwe endaweni yokusebenzela ngemva kokucubungula. Uhlelo lwe-vacuum ludala indawo enengcindezi ephansi yegumbi lokomisa le-sublimation, uhlelo lokufudumeza lunikeza ukushisa okucashile kwe-sublimation ezintweni, kanti uhlelo lokuqandisa lunikeza amandla okupholisa adingekayo egumbini lokubanda le-cold trap kanye nokomisa.
Lo mshini usebenzisa ukushisa kwemisebe okusebenzayo, okuqinisekisa ukusatshalaliswa kokushisa okufanayo ezintweni. Une-trap yokubamba umhwamuko wamanzi ephumelelayo enekhono lokuncibilikisa ngokushesha, iyunithi ye-vacuum esebenza kahle kakhulu enokuhlukaniswa kwamafutha namanzi, kanye nesistimu yokuqandisa ephakathi ehambisanayo enikeza ukupholisa uma kudingeka ngamasekethe amaningi, okuholela ezimweni zokusebenza ezizinzile nokonga amandla. Uhlelo lokulawula ubuhlakani bokwenziwa luqinisekisa ukunemba okuphezulu nokusebenza okulula.
Izidingo zekhwalithi zemikhiqizo eyomiswe ngokuqandisa zifaka: umsebenzi webhayoloji ongashintshi, ukubukeka nombala ofanayo, isimo somzimba esiqinile, isakhiwo esiqinile, ukuncibilika okusheshayo, kanye nomswakama ophansi osele. Ukuze uthole imikhiqizo esezingeni eliphezulu, ukuqonda okuphelele kwethiyori yokomisa ngokuqandisa kubalulekile. Inqubo yokomisa ngokuqandisa inezigaba ezintathu: ukuqandisa ngaphambi kokuqandisa, ukuncibilikisa, kanye nokomisa kwesibili. Ukunciphisa umjikelezo wokuqandisa ngokufanele nangokuphumelelayo kunokubaluleka okukhulu kwezomnotho ekukhiqizweni kwezimboni.
