Mumakore achangopfuura, zvinodiwa zvevanhu zvekurongedza zvakakwirira zvakanyanya kupfuura kare, sakavacuum packaging muchinavagadziri vakaisa mari yakawanda yevanhu uye zviwanikwa mukutsvaga nekusimudzira nekugadzira michina yekuisa vacuum. Iye zvino kurongedza pamusika kwakasiyana-siyana, uye mabasa anogadzirwa zvakanyanya. Vacuum yekurongedza michina inodzivirira kuparara kwechikafu nekudzikisa mwero weokisijeni. Sezvo kuparara kwechikafu kuchikonzerwa nekuita kwemicrobial, okisijeni inodiwa pakurarama kweakawanda microorganisms. Iyo vacuum packer ndicho chikonzero chemitengo yekutumira. Homwe dzeokisijeni dzinovhara, zvichiita kuti zvisaite kuti tupukanana tirarame munzvimbo. Kana huwandu hweokisijeni mubhegi huri pasi pe1%, kukura uye kubereka chiyero che microorganisms chinodonha zvakanyanya. Kukura kwakagumiswa apo iyo oxygen concentration yaive isingasviki 05%. Iwo ese ese semi-vacuum ekurongedza machina, anonyanya kushandiswa mundima iyi.

Zvimwe zvikafu zvisina kusimba zvinoshandisa inflatablevacuum packaging muchina, nokuti bhegi rinozadza gasi rinogona kunyatsodzivisa kuputsa zvokudya. Nokudaro kukanganisa chitarisiko uye kushandiswa. Iyo vacuum inflatable yekurongedza muchina wakazadzwa neN2. Carbon dioxide, oxygen kana musanganiswa wemagasi akasiyana Nitrogen igasi inert uye inoita basa rekuzadza. Carbon dioxide inonyungudika mumvura kana mafuta kuumba weakly acidic carbonic acid, iyo inogona kunyatso kuvharidzira simba rezvipembenene. Okisijeni inochengetedza ruvara rwemichero nemiriwo. Kuwanda kweokisijeni kunochengeta nyama tsvuku itsva yakatsvuka.
