Modified Atmosphere Packaging, yomwe imatchedwanso MAP, ndiukadaulo watsopano wosunga chakudya chatsopano ndipo umatenga mpweya wosakanikirana (carbon dioxide, oxygen, nitrogen, etc.) kuti ulowe m'malo mwa mpweya womwe uli mu phukusi.
Kupaka m'mlengalenga kumagwiritsa ntchito magawo osiyanasiyana amipweya yodzitchinjiriza kuti alepheretse kukula ndi kuberekana kwa tizilombo tambiri timene timayambitsa kuwonongeka kwa chakudya, komanso kuchepetsa kupuma kwachakudya chogwira ntchito (zakudya zakutchire monga zipatso ndi ndiwo zamasamba), kuti chakudya chizikhala chatsopano ndikutalikitsa. nthawi yosungira.
Monga tonse tikudziwira, kuchuluka kwa mpweya mumlengalenga kumakhazikika.78% ya Nayitrogeni, 21% ya Oxygen, 0.031% ya Carbon dioxide, ndi mpweya wina.MAP imatha kusintha kuchuluka kwa gasi pogwiritsa ntchito njira zopangira.Zotsatira za carbon dioxide ndizomwe zimalepheretsa kukula kwa mabakiteriya ndi bowa, makamaka panthawi yoyamba ya kukula kwake.Mpweya wokhala ndi 20% -30% wa carbon dioxide umayendetsa bwino kukula kwa mabakiteriya m'malo otsika kutentha, madigiri 0-4.Komanso, nayitrogeni ndi imodzi mwa mpweya inert, izo zingalepheretse oxidization zakudya ndi ziletsa nkhungu kukula.Mphamvu ya okosijeni pa chakudya ndikusunga mitundu ndikulepheretsa kuberekana kwa mabakiteriya a anaerobic.Poyerekeza ndi kulongedza kwa khungu la vacuum kuchokera kumbali ya mtundu, mawonekedwe a MAP osungira mitundu mwachiwonekere ndi aakulu kuposa a VSP.MAP imatha kusunga nyama kukhala yofiira, koma nyamayo imakhala lavenda.Ichi ndichifukwa chake makasitomala ambiri amakonda chakudya cha MAP.
Ubwino wa makina a MAP
1. Mawonekedwe a makompyuta a anthu amapangidwa ndi PLC ndi chophimba chokhudza.Othandizira amatha kukhazikitsa magawo owongolera.Ndizosavuta kuti oyendetsa aziwongolera ndipo ali ndi kulephera kochepa.
2. Njira yolongedza ndi yakuti vacuum, kupukuta gasi, kusindikiza, kudula, ndiyeno kunyamula trays.
3. Zida zathu zamakina a MAP ndi 304 zitsulo zosapanga dzimbiri.
4. Mapangidwe a makinawo ndi osakanikirana komanso osavuta kugwiritsa ntchito.
5. Nkhungu imasinthidwa makonda, malinga ndi kukula kwa thireyi ndi mawonekedwe.
