Kukonza Zinthu Zosasinthika, komwe kumatchedwanso MAP, ndi ukadaulo watsopano wosungira chakudya chatsopano ndipo umagwiritsa ntchito mpweya woteteza (carbon dioxide, oxygen, nayitrogeni, ndi zina zotero) kuti ulowe m'malo mwa mpweya womwe uli mu phukusi.
Ma phukusi osinthidwa a mpweya woteteza amagwiritsa ntchito ntchito zosiyanasiyana za mpweya woteteza kuti alepheretse kukula ndi kuberekana kwa tizilombo toyambitsa matenda ambiri omwe amachititsa kuti chakudya chiwonongeke, ndikuchepetsa kuchuluka kwa kupuma kwa chakudya chogwira ntchito (zakudya za zomera monga zipatso ndi ndiwo zamasamba), kuti chakudya chikhale chatsopano ndikuwonjezera nthawi yosungira.
Monga tonse tikudziwira, kuchuluka kwa mpweya mumlengalenga ndi kokhazikika. 78% ya nayitrogeni, 21% ya mpweya, 0.031% ya mpweya wa kaboni, ndi mpweya wina. MAP ikhoza kusintha kuchuluka kwa mpweya pogwiritsa ntchito njira zopangira. Mphamvu ya kaboni dioksijeni ndi yomwe imaletsa kukula kwa mabakiteriya ndi bowa, makamaka panthawi yoyambirira ya kukula kwake. Mpweya wokhala ndi 20%-30% ya mpweya wa kaboni dioksijeni umalamulira bwino kukula kwa mabakiteriya pamalo otentha kwambiri, madigiri 0-4. Kuphatikiza apo, nayitrogeni ndi imodzi mwa mpweya wopanda mphamvu, imatha kuletsa okosijeni wa zakudya ndikuletsa kukula kwa nkhungu. Mphamvu ya mpweya pa chakudya ndi kusunga mtundu ndikuletsa kuberekana kwa mabakiteriya a anaerobic. Poyerekeza ndi kulongedza khungu la vacuum kuchokera mbali ya mtundu, mphamvu ya MAP yosunga mtundu ndi yayikulu kuposa ya VSP. MAP imatha kusunga nyama yofiira kwambiri, koma nyama idzakhala lavenda. Ichi ndichifukwa chake makasitomala ambiri amakonda chakudya cha MAP.
Ubwino wa makina a MAP
1. Chida cholumikizirana ndi kompyuta cha munthu chimapangidwa ndi PLC ndi chophimba chokhudza. Ogwiritsa ntchito amatha kukhazikitsa magawo owongolera. Ndikosavuta kwa ogwiritsa ntchito kuwongolera ndipo ali ndi chiwopsezo chochepa cha kulephera.
2. Njira yopakira ndi vacuum, gasi flush, seal, cut, and then took the trays.
3. Zipangizo za makina athu a MAP ndi chitsulo chosapanga dzimbiri cha 304.
4. Kapangidwe ka makina ndi kakang'ono komanso kosavuta kugwiritsa ntchito.
5. Nkhungu imasinthidwa malinga ndi kukula kwa thireyi ndi mawonekedwe ake.
