Umshini wokupakisha we-Vacuum ungakhipha umoya ngokuzenzakalela esikhwameni sokupakisha, bese uqedela inqubo yokuvalwa ngemuva kokufinyelela iziqu ze-vacuum ezinqunyelwe kusengaphambili. Ingagcwaliswa futhi ne-nitrogen noma enye igesi exubile, bese uqedela inqubo yokuvalwa kokubekwa uphawu. Imishini yokupakisha ye-Vacuum ivame ukusetshenziswa embonini yokudla, ngoba ngemuva kokupakishwa kwe-vacuum, ukudla kungamelana ne-oxiphation, ukuze kufezeke injongo yokulondolozwa kwesikhathi eside.
Esikhaleni esikhethiwe, isimo segesi esingaphansi kwesimo esisodwa sengcindezi kubhekiselwa kuyo njenge-vacuum. Izinga lokuncipha kwegesi esimweni se-vacuum libizwa ngokuthi yi-vacuum, evame ukuvezwa yinani lokucindezela. Ngakho-ke, ukupakishwa kwe-vacuum empeleni akulona i-vacuum ngokuphelele, kanye neziqu ze-vacuum esitsheni sokudla esifakwe ubuchwepheshe bokupakisha ye-vacuum kuvame ukuba ngu-600-1333PA.
Umsebenzi oyinhloko wokupakishwa we-vacuum ukususa umoya-mpilo. Ngakolunye uhlangothi, kwenza ama-microorganis alahlekelwe yindawo yawo yokuphila, avimbela ukuphefumula kwawo futhi avimba ukuzalwa kabusha, ngakolunye uhlangothi, agweme ukuwohloka, ukonakala kanye noshintsho lombala okubangelwa yi-oxidation yokudla.
Inyama entsha neminye imikhiqizo, ingxenye elungisiwe ye-O2, N2 ne-CO2 ngemuva kokufaka ukufakwa kwamanzi okuvuthayo kungavimba ukukhiqizwa kwamagciwane anaerobic, bese wenza imikhiqizo ekhanyayo ibe nokuncintisana ngokwengeziwe.
