Ibanga elijwayelekile le-vacuum le-vacuum freeze dryer livamise ukuba phakathi kuka-10 Pa kanye no-1000 Pa, ngevelu ethile ethonywa yizinto ezibonakalayo nobuchwepheshe bokucubungula. Lolu hlu lwe-vacuum luzuzisa ukusheshisa izinga le-sublimation kanye nokuthuthukisa ukusebenza kahle kokomisa.
Izinga le-vacuum le-vacuum freeze dryer libhekisela ezingeni lapho umfutho wegesi wangaphakathi uphansi kakhulu kunomfutho womoya wangaphandle. Le parameter ibalulekile ekusebenzeni okuvamile kwemishini kanye nomthelela wokomisa. Kodwa-ke, alikho inani elifanayo nenani elingaguquki lezinga elivamile le-vacuum yokomisa iqhwa, njengoba lithintwa izici ezihlukahlukene, okuhlanganisa uhlobo, imininingwane, ukusetshenziswa, nezimo zokusebenza zemishini.
