Modified Atmosphere Packaging, iyo inodaidzwa zvakare kuti MAP, tekinoroji nyowani yekuchengetedza chikafu chitsva uye inotora musanganiswa unodzivirira wegasi (carbon dioxide, oxygen, nitrogen, etc.) kutsiva mweya uri mupakeji.
Yakagadziridzwa mamiriro ekurongedza anoshandisa akasiyana mabasa eakasiyana ekudzivirira gasi kutadzisa kukura uye kuberekana kweakawanda tupukanana tunokonzera kukanganisa kwechikafu, uye kuderedza kufema kwechikafu chinoshanda (zvinomera zvakaita semichero nemiriwo), kuitira kuti chikafu chirambe chiri chitsva uye kurebesa. nguva yekuchengetedza.
Sezvatinoziva tose, chikamu chegasi mumhepo chinogadziriswa.78% yeNitrogen, 21% yeOxygen,0.031% yeCarbon dioxide, uye imwe gasi.MAP inogona kushandura chikamu chegasi nenzira yemaitiro ekugadzira.Mhedzisiro yekabhoni dhaibhoni ndeyekuti inodzora kukura kwebhakitiriya uye fungus, kunyanya panguva yekutanga chikamu chekukura kwayo.Gasi rine 20% -30% ye carbon dioxide zvakanaka inodzora kukura kwebhakitiriya munzvimbo yekushisa kwakadzika, 0-4 degrees.Mukuwedzera, nitrogen ndeimwe yemagasi anert, inogona kudzivirira oxidization yezvokudya uye inhibit mold kukura.Mhedzisiro yeokisijeni yechikafu kuchengetedza ruvara uye inotadzisa kuberekana kweanaerobic bacteria.Kuenzaniswa nekuputirwa kweganda revacuum kubva pakona yeruvara, MAP's color-cheep effect iripachena yakakura kupfuura VSP's.MAP inogona kuchengetedza nyama yakatsvuka, asi nyama ichava lavender.Ichi ndicho chikonzero nei vatengi vazhinji vachifarira MAP chikafu.
Zvakanakira zveMAP muchina
1. Iyo yemunhu-kombuta interface inoumbwa nePLC uye touch screen.Vashandisi vanogona kuseta iyo control parameter.Izvo zviri nyore kune vashandisi kudzora uye ine yakaderera yekutadza mwero.
2. Iyo yekurongedza maitiro ndeye vacuum, gasi flush, chisimbiso, cheka, uye wozotora matireyi kumusoro.
3. Yedu MAP michina 'zvinhu ndeye 304 simbi isina tsvina.
4. Chimiro chemuchina chakabatana uye chiri nyore kushanda.
5. Mold inogadziriswa, maererano nehukuru hwetireyi uye chimiro.
