Vacuum packaging ndeyekusimbisa zvinhu mushure mekunge mhepo iri mubhegi rekurongedza yaburitswa, kuitira kuti uwane chinangwa chekuchengeta kutsva uye kwenguva refu kuchengetedza kwezvinhu zvakaputirwa, uye yakanakira kutakura uye kuchengetedza.Vacuum packaging equipment muchina unobvisa mweya mukati memudziyo mushure mekunge chigadzirwa chacho chaiswa mumudziyo wekurongedza, unosvika padanho rakatemerwa vacuum (kazhinji ingangoita 2000 ~ 2500Pa) uye unopedzisa kuiswa chisimbiso.Inogonawo kuzadzwa ne nitrogen kana imwe gasi yakasanganiswa, uye wozopedzisa kuisa chisimbiso.
Vacuum yekurongedza tekinoroji yanga iripo kubva kuma1940s.Kusvikira pakati uye pakupera 50s, vacuum kurongedza munda zvishoma nezvishoma akatanga kushandisa polyethylene nemamwe epurasitiki mafirimu kurongedza.Mukutanga 1980s, nekukurumidza kukura kweindastiri yekutengesa uye zvishoma nezvishoma kusimudzirwa kwezviputi zviduku, teknolojia yakashandiswa uye yakagadzirwa.Vacuum packaging inokodzera marudzi ese epurasitiki akaumbwa emabhegi emufirimu kana aluminium foil composite firimu mabhegi, akadai sepolyester / polyethylene, nylon / polyethylene, polypropylene / polyethylene, polyester / aluminium foil / polyethylene, nylon / aluminium foil / polyethylene. .Nekuenderera mberi nekuvandudzwa kwekuziva kwevanhu, kushandiswa kwevacuum yekurongedza muchina kwakwezva kutarisisa kwakawanda kubva kune chikafu, machira, zvemagetsi uye mamwe maindasitiri.
Nekuenderera mberi kwekuvandudzwa kwesainzi uye tekinoroji uye nekuenderera mberi kwekuvandudzwa kwemararamiro evanhu, kushandiswa kwevacuum yekurongedza tekinoroji kuchawedzera uye kuwanda, uye siyana, chimiro, kuita uye kunaka kwemidziyo yekurongedza yevacuum ichachinja nekuvandudza.Muindasitiri yemachira uye yemaoko, vacuum packaging inogona kunyatso kudzikisa huwandu hwezvigadzirwa uye kufambisa kurongedza uye kutakura;muindasitiri yezvekudya, vacuum packaging uye sterilization process inogona kunyatso kurambidza kubereka kwebhakitiriya, kunonoka kuparara kwechikafu, uye kuwedzera hupenyu hwesherufu yekudya;Muindasitiri yehardware, vacuum-packed hardware accessories inogona kutsaura okisijeni, kuitira kuti zvishongedzo zvisaite oxidize uye ngura.
Chimiro chevacuum yekurongedza midziyo yakasiyana, uye nzira yekuisa nayo yakasiyana.Kazhinji, inogona kukamurwa kuita mechanical extrusion type, intubation type, chamber type, etc. maererano nekupeta nzira dzakasiyana;maererano nenzira iyo zvinhu zvakaputirwa zvinopinda mukamuri, inogona kupatsanurwa kuva-single-chamber, kaviri-chamber, thermoforming, conveyor bhandi, rotary vacuum chamber Maererano nemaitiro ekufambisa, inogona kugoverwa kuva intermittent type uye inoenderera mberi;zvinoenderana nehukama pakati pechigadzirwa chakaputirwa nemudziyo wekurongedza, inogona kupatsanurwa kuita vacuum body packaging uye vacuum inflatable packaging.
