Ubhanana ungomunye wezithelo esivame ukuzidla. Ukuze balondoloze izakhi zokudla okunempilo kanye nombala wokuqala wemikhiqizo ecutshungulwe ngobhanana, abacwaningi basebenzisaFukuphindaDi-ryer ukuze kwenziwe izifundo zokomisa nge-vacuum freezer. Ucwaningo lokomisa nge-freezer ngobhanana lugxile kakhulu ezingcezwini zikabhanana kanye nempuphu kabhanana.
Inqubo yokomisa nge-frozen yempuphu kabhanana ihlanganisa ikakhulukazi izinyathelo eziningana: ukwelashwa kwangaphambi kwesikhathi, ukuqandisa, ukomisa nge-sublimation, ukomisa nge-desorption, kanye nokupakishwa. Ukwelashwa kwangaphambi kwesikhathi kuhilela ukuhlubula, ukunquma, kanye nokugaya ubhanana ukuze kube lula ukomisa okulandelayo. Ukuqothula kwangaphambi kwesikhathi kuhilela ukuqandisa i-pulp kabhanana ekushiseni okuthile ukuze kwakheke i-sublimation interface eqinile ngesikhathi sesigaba sokomisa nge-sublimation. Ukomisa nge-sublimation kuhilela ukushisa i-pulp kabhanana eqandisiwe ngaphansi kwezimo ze-vacuum ukuze kususwe umswakama nge-sublimation. Ukomisa nge-desorption kususa umswakama osele ukuze kufezwe ukoma okudingekayo. Ekugcineni, i-powder kabhanana epakishiwe isilungele ukudayiswa.
Imingcele eminingana ebalulekile kumele ilawulwe ngokuqinile ngesikhathi sokomiswa kweqhwa ukuqinisekisa ikhwalithi yomkhiqizo. Okokuqala,ukujiya kwezinto ezibonakalayo: Njengoba ubhanana uqinile kakhulu, ukujiya okufanayo kumele kugcinwe ngesikhathi sokukhiqiza ukuvimbela izinkinga ezifana nokungahlanganisi noma ukoma okungaphelele. Okwesibili,izinga lokushisa lokushisa ngesikhathi sokufakwa kwe-sublimation: Ukuhlolwa kubonisa ukuthi isikhathi sokomisa siyancipha njengoba izinga lokushisa eshalofini likhuphuka ngaphakathi kwebanga elifanele (≤20°C). Kodwa-ke, ukushisa ngokweqile ngaphansi kwengcindezi ephezulu yokusebenza kungabangela ukuncibilika komkhiqizo, okudinga imikhawulo yokushisa. Okokugcina,ingcindezi ye-sublimation: Ingcindezi yokusebenza ithinta kakhulu ukushisa kanye nokudluliselwa kwesisindo. Izifundo zibonisa ingcindezi efanele (cishe i-40Pa) enciphisa isikhathi sokoma.
Ijika lokuqandisa lisebenza njengesibonakaliso esibalulekile senqubo yokomisa. Ngokuhlaziya amajika ngaphansi kwezimo ezahlukene, amapharamitha enqubo angathuthukiswa. Isibonelo, ngaphansi kwezimo ezifanele (ubukhulu obungu-8mm, ukushisa okungu-20°C, ingcindezi engu-40Pa), ijika lokuqandisa libonisa izigaba ezizinzile zokuncibilikisa kanye nokuncibilikisa, isikhathi esifushane sokomisa, kanye nekhwalithi yomkhiqizo ephezulu.
Ama-dryer dryers abonisa izinzuzo ezibalulekile kanye namathuba amaningi okusetshenziswa ekukhiqizweni kwempuphu kabhanana. Ngokulawula ngokuqinile imingcele ebalulekile kanye nokwenza ngcono izinqubo, kokubili ikhwalithi yomkhiqizo kanye nokusebenza kahle kokukhiqiza kungathuthukiswa. Namuhla, njengoba amazinga ekhwalithi yokudla ekhuphuka, uhla oluhlukahlukene lwe-dryer dryers lwe-BOTH—olwenzelwe izidingo zekhwalithi ephezulu—luye lwamukelwa kabanzi.Siyakwamukela ukubuzaukuthola imininingwane eyengeziwe.
