Mazuvano tinoenda kuzvitoro tichawana chikafu chakawanda zvesevacuum-packed bags, rudzi urwu rwekurongedza inzira iyo gasi riri muchikafu rinopombwa kuti ribudise mabhegi ane vacuum-packed.Izvi zvinogona kuwedzera nguva yekuchengetedza yezvokudya, chikafu chemukati chinowedzerawo hutano hwezvakatipoteredza uye hutano hwepanyama uye hwepfungwa, saka isu tose tinoda kutenga vacuum-packed masaga ezvokudya, asi kunyange zvazvo inogona kuwedzera nguva yekuchengetedza, asiwo kupedzwa. mukati menguva yekuchengetedza.
Mushure mekurongedza vacuum, marudzi akasiyana echikafu ane nguva dzakasiyana dzekuchengetera patembiricha yekamuri.
Kazhinji, zvigadzirwa zvitsva kana nyama yakagadziridzwa zvishoma inogona kuchengetwa mukamuri tembiricha kusvika mazuva maviri.Kana vacuum-yakazara, izvi zvinogona kuwedzerwa kusvika kumazuva matanhatu uye mune dzimwe nguva kusvika kumazuva gumi nemasere.Muchero wakaomeswa unogona kuchengetwa kwenguva yakareba, kunyange kupfuura mwedzi gumi nembiri.Zvokudya zvakabikwa zvishoma.Kazhinji, inogara iri nyowani kwemazuva angangoita gumi nemashanu muchando uye muchirimo, uye mazuva mana chete kusvika 1 vhiki muzhizha uye matsutso, uye iri nani mufiriji.
Nheyo yekuchengetedzwa kwekudya mukativacuum packagingkunonyanya kubviswa kweokisijeni.Kuparara kwechikafu kunokonzerwa nekukura uye kuwanda kwezvipukanana uye mabhakitiriya.
Zvizhinji zvipenyu, senge mold uye mbiriso, zvinoda oxygen kuti irarame.Chikafu chakazara-vacuum chinobvisa okisijeni kubva pakurongedzerwa, izvo zvinotadzisawo kukura uye kuwanda kwema microorganisms.Iwo unsaturated fatty acids ari mumafuta nemafuta anotapukirwa neoxidation uye kuora.Kana iyo vacuum iine deoxygenated, inodzivirirawo chikafu kubva kune oxidising.
Mushure mekubuda, chikafu chisina kusimba uye chakaremara chinozadzwa nemusanganiswa wemagasi, senge carbon dioxide uye nitrogen.Inoita sechizadziso kuitira kuti kudzvinyirirwa mukati nekunze kwebhegi kwakasimba kudarika kudzvinyirira kunze kwebhegi.Izvi hazvidziviriri chete mhepo kupinda mubhegi kubva kunze, asiwo inodzivirira chikafu kubva pakupwanyika uye kuremara.
Yixing Boya New Material tekinoroji Co., LTD yakavambwa muna Gumiguru 2018 nyanzvi mukutsvaga, kugadzira uye kutengesa inochinjika yakawanda-layer coextruded functional packaging materials.Kana uchida rumwe ruzivo, ndapota inzwa wakasununguka kutibata nesu.
