I-Modified Atmosphere Packaging, ebizwa nangokuthi i-MAP, ubuchwepheshe obusha bokulondolozwa kokudla okusha futhi isebenzisa ingxube evikelayo yegesi (i-carbon dioxide, i-oxygen, i-nitrogen, njll.) ukuze ithathe indawo yomoya osephaketheni.
Ukupakishwa komoya okushintshiwe kusebenzisa izindima ezahlukene zamagesi ahlukahlukene okuvikela ukuvimbela ukukhula nokuzalana kwamagciwane amaningi abangela ukonakala kokudla, nokunciphisa izinga lokuphefumula kokudla okusebenzayo (ukudla kwezitshalo njengezithelo nemifino), ukuze kugcinwe ukudla kusha futhi kwandise isikhathi sokulondolozwa.
Njengoba sonke sazi, isilinganiso samagesi emoyeni sizinzile. 78% we-nitrogen, 21% we-oxygen, 0.031% we-carbon dioxide, kanye nenye igesi. I-MAP ingashintsha isilinganiso segesi ngokwesilinganiso sezindlela zokwenziwa. Umphumela we-carbon dioxide ukuthi uvimbela ukukhula kwamagciwane kanye nesikhunta, ikakhulukazi ngesikhathi sokuqala kokukhula kwayo. Igesi equkethe u-20%-30% we-carbon dioxide ilawula kahle ukukhula kwamagciwane endaweni enokushisa okuphansi, ama-degrees angu-0-4. Ngaphezu kwalokho, i-nitrogen ingenye yamagesi angasebenzi, ingavimbela ukungcoliswa kokudla futhi ivimbele ukukhula kwesikhunta. Umphumela we-oxygen ekudleni ukugcina umbala futhi uvimbela ukukhiqizwa kwamagciwane angenawo umoya. Uma kuqhathaniswa nokupakishwa kwesikhumba se-vacuum kusuka ekhoneni lombala, umphumela we-MAP wokugcina umbala ngokusobala mkhulu kune-VSP. I-MAP ingagcina inyama ibomvu ngokugqamile, kodwa inyama izoba lavender. Lesi yisizathu esenza amakhasimende amaningi akhethe ukudla kwe-MAP.
Izinzuzo zomshini we-MAP
1. Isixhumi esibonakalayo sekhompyutha yomuntu sakhiwe yi-PLC kanye nesikrini sokuthinta. Abasebenzi bangasetha amapharamitha okulawula. Kulula ukuthi abaqhubi balawule futhi kunesilinganiso sokuhluleka esiphansi.
2. Inqubo yokupakisha iwukuhlanza igesi, ukufutha, ukuvala, ukusika, bese uthatha amathreyi.
3. Izinto zomshini wethu we-MAP ziyinsimbi engagqwali engu-304.
4. Isakhiwo somshini sincane futhi kulula ukusebenza.
5. Isikhunta senziwe ngokwezifiso, ngokuya ngobukhulu bethileyi kanye nesimo.
