Munzanga yanhasi, mararamiro evanhu ari kuramba achivandudza, nhanho yehupenyu iri kukurumidza, uye nguva shoma haigoni kuenderana nekuwedzera kudiwa kwevanhu.Vanhu vazhinji vanoda chikafu, asi kune vashoma vanhu vane nguva uye kufarira mumaoko chaiwo.Nokudaro, zvigadzirwa zvekudya zvakabikwa zvakabuda.Zvitoro zvezvokudya zvakapfava zviri kuramba zvichionekwa nevanhu, uye kune macheni akasiyana echikafu chakabikwa pese pese mumugwagwa.Zvisinei, zvokudya zvakabikwa hazviwanzochengetwi nyore, uye kuchengetedzwa kusina kufanira kunokombamirawo kukushata.Kubuda kwemashini ekurongedza chikafu chekudya kwakagadzirisa dambudziko iri.Chikafu vacuum yekurongedza muchina unogona kuita bhegi mune vacuum state kuti uwane sterility.

Kune zvigadzirwa zvenyama, deoxygenation inogona kutadzisa kukura uye kukura kwe mold uye aerobic mabhakitiriya, inhibisa oxidation yezvikamu zvemafuta, kudzivirira kuparara kwechikafu, uye kuwana kuchengetedza uye hupenyu hwesherufu.

Kune muchero, okisijeni mukati mehomwe inoderedzwa, uye chibereko chacho chishoma.Iyo inoburitsa kabhoni dhaidhiyo kuburikidza nekufema kweanaerobic uku ichichengetedza humwe hunyoro.Iyi yakaderera-oxygen, high-carbon dioxide, uye yakakwirira-humidity nharaunda inogona kuderedza zvinobudirira kubuda kwemichero uye kuderedza kutetepa kwemichero.Kufema, kuderedza kugadzirwa kwe ethylene uye kushandiswa kwezvinovaka muviri, kuitira kuti uwane chinangwa chekuchengetedza.

Iyo chiyero chekushandiswa kwechikafu vacuum yekurongedza michina inosanganisira:

Zvigadzirwa zvakabikwa: soseji, ham uye mimwe miriwo yakabikwa, senge mustard, radish, pickles, nezvimwewo;

Nyama itsva: nyama yemombe, gwayana, nguruve, nezvimwewo.

Zvigadzirwa zvebhinzi: bhinzi yakaomeswa, bhinzi paste, nezvimwewo;

Zvigadzirwa zvakabikwa: nyama yemombe, huku yakakangwa, nezvimwewo;

Zvokudya zviri nyore: mupunga, miriwo, chikafu chemumagaba, nezvimwe.

Pamusoro pezvikafu zviri pamusoro, zvinoshandawo pakuchengetedzwa kwemishonga, makemikari zvinhu, zvigadzirwa zvesimbi, zvigadzirwa zvemagetsi, machira, zvekurapa, uye zvetsika zvinhu.Nekudaro, zvinofanirwa kucherechedzwa kuti vacuum packaging haina kukodzera kurongedza uye kuchengetedza chikafu chisina kusimba uye chisina kusimba, inopinza-angled mabhegi epurasitiki ekurongedza, uye zvinyoro uye zvinoremara chikafu.

Kubuda kwechikafu vacuum yekurongedza muchina kwakapa mamiriro ekusimudzira uye kuwedzera kwechikafu chakabikwa, kuitira kuti zvigadzirwa zvechikafu zvakabikwa zvisisiri pasi pemamiriro enzvimbo uye nguva, uye kuvandudzwa kwemapapiro maviri kunzvimbo yakafara yekusimudzira.Pamusoro pezvo, michina yekurongedza chikafu inofambirana nekukasira kudiwa kwezvitsva uye nekukurumidza kurongedza muzvigadzirwa zvemazuva ano, uye kukurudzira kukurumidza kusimudzira hupfumi hwemusika.Kune vanogadzira, michina yekurongedza yekudya vacuum inogona kudzikisa mari yekugadzira yekambani, uye kuwana mari shoma uye mari yakawanda.
