Modified Atmosphere Packaging, iyo inonziwo MAP, itekinoroji itsva yekuchengetedza chikafu chitsva uye inoshandisa musanganiswa wegasi unodzivirira (carbon dioxide, oxygen, nitrogen, nezvimwewo) kutsiva mhepo iri mupakeji.
Kurongedza kwakagadziridzwa kwemhepo kunoshandisa mabasa akasiyana-siyana emagasi anodzivirira kudzivirira kukura nekuberekana kwetupukanana tunokonzera kuora kwechikafu, uye kuderedza mwero wekufema kwechikafu chinoshanda (chikafu chezvirimwa chakadai semichero nemiriwo), kuitira kuchengetedza chikafu chitsva uye kuwedzera nguva yekuchengetedza.
Sezvatinoziva tese, huwandu hwemagasi ari mumhepo hwakagadzika. 78% yeNitrogen, 21% yeOxygen, 0.031% yeCarbon dioxide, nedzimwe gasi. MAP inogona kushandura huwandu hwegasi kuburikidza nenzira dzekugadzira. Mhedzisiro yekabhoni dioxide ndeyekuti inodzora kukura kwebhakitiriya nefungus, kunyanya panguva yekutanga kwekukura kwayo. Gasi rine 20%-30% yekabhoni dioxide rinodzora kukura kwebhakitiriya munzvimbo ine tembiricha yakaderera, 0-4 degrees. Pamusoro pezvo, nitrogen ndeimwe yemagasi asina simba, inogona kudzivirira oxidization yechikafu uye kudzivirira kukura kwefungus. Mhedzisiro yeoxygen yechikafu ndeyekuchengetedza mavara uye inodzivisa kuberekana kwebhakitiriya isina aerobic. Zvichienzaniswa nekurongedza ganda kubva pakona yeruvara, MAP inochengetedza mavara zviri pachena kupfuura VSP. MAP inogona kuchengetedza nyama yakatsvuka, asi nyama ichava lavender. Ichi ndicho chikonzero nei vatengi vazhinji vachida chikafu cheMAP.
Zvakanakira zvemuchina weMAP
1. Hunhu hwekombiyuta hunosanganisira PLC ne touch screen. Vashandisi vanogona kuseta ma parameter ekudzora. Zviri nyore kuti vashandisi vatonge uye ine failure rate yakaderera.
2. Maitiro ekurongedza ndeekuti vacuum cleaner, gas flush, seal, cheka, wozotora matireyi.
3. Zvinhu zvemuchina wedu weMAP isimbi isingasvibi 304.
4. Maumbirwo emuchina wacho akamanikana uye ari nyore kushandisa.
5. Mould inogadziriswa, zvichienderana nehukuru hwetireyi uye chimiro.
