Ambiri amadya chakudya chochulukitsidwa tsiku ndi tsiku. Zili bwino komanso zosavuta kunyamula ndi kusunga. Zakudya zowonongeka zimafunika chitetezo chochuluka, kuchokera ku chomera kupita ku golosale, ndi ku khitchini yanu. Ndiponso, mungafunikire kusunga iwo kwa kanthawi musanawagwiritse ntchito.
Zakudya zouma nthawi zambiri zimakhala mu matumba ndi mabokosi. Chinsinsi cha kusungika kwa nthawi yaitali ndichochotsa mpweya wa oksijeni m'mitsuko chifukwa kutentha kwa mpweya kumayambitsa chakudya.
Mafuta adzapita pang'onopang'ono, kusungunuka kwa chakudya kumapezeka, ndi zokolola zomwe zimapangidwira ndikupita kukasakaza. Pali njira ziwiri zomwe mungakwaniritsire izi, phalapula kapena nitrogen.
Pukuta Packaging
Gawo loyamba lopaka phukusi ndikutenga chakudya mu thumba. Kenaka, thumba limagwirizanitsidwa ndi mpweya, ndipo mpweya umachotsedwa, zomwe zimatengera oksijeni pamodzi nawo. Thumba limasindikizidwa, ndipo mankhwalawa ndi okonzeka kukhala malemba ndi kutumizidwa.
Kupaka phokoso nthawi zonse kumapanga zakudya zabwino zamphamvu monga nyama yamphongo ndi nyama yatsopano, koma sizigwira ntchito bwino zakudya zomwe sizowonongeka, monga ziwombankhanga ndi opanga. Zakudya izi zimafunika kutetezedwa paulendo kuti asaphedwe kapena kusweka. Zakudya monga nyemba za khofi zomwe zili ndi malo ambiri ndipo sungagwiritsidwe mthunzi wopanda mpweya zingafunike zina zowonjezera zowonjezera.
Asitrogeni Flushing
Pamene mutenga thumba la zipsya zopanda pake, mumatha kumva ndikumva zipsera zikuzungulira, ndipo zikuwoneka ngati pali mpweya wambiri mu thumba kusiyana ndi makapu enieni.
Koma sizili ngati mpweya umene mumapuma chifukwa phukusilo mulibe mpweya. Zonse zomwe 'mpweya' ndi mafuta a nayitrogeni.
Zipangizo zamakono ndi zowonjezera sizimadzaza ndi nayitrogeni gasi basi amawoneka aakulu. Matumbawa apangidwa m'njira yotetezera zakudya zolimbitsa mkati mkati mwazidziwitso za oksijeni komanso kuwonongeka kwa thupi.
Nitrojeni imalowa m'malo mwa mpweya ndi mpikisano.
Mosiyana ndi oksijeni, nayitrogeni sichita ndi zakudya, kotero zimakhala zotsalira kwambiri. Izi ndizofunikira ndithu, koma nayitrojeni sizimakhudza zokoma kapena kapangidwe ka chakudya, choncho ndizotheka kusunga chakudya. Ndipo palibe nkhawa za gasiti ya nitrojeni. Ndi otetezeka kwathunthu. Ndipotu, mumakhala ndi nayitrogeni nthawi zonse chifukwa zimakhala pafupifupi 70 peresenti ya mpweya umene mumapuma.
Momwe Ikugwirira Ntchito
Choyamba, chakudya chikuwonjezeredwa phukusi lotseguka, chinachake monga pulasitiki kapena thumba langa. Kenaka, opanga zakudya amagwiritsa ntchito makina omwe amachititsa mpweya wokhala ndi mpweya wokhazikika kuchokera m'matumba ndipo nthawi yomweyo mudzawadzoze ndi mafuta a nitrogen. Ndiye, asafejeni asanathe kuthawa, makina amasindikiza matumbawo mwamphamvu. Matumbawa amaikidwa m'mabokosi akuluakulu ndi kutumizidwa ku masitolo ogulitsa, malo ogulitsa, ndi malo odyera.
Phukusi zodzaza nayitrogeni zimateteza kuteteza zakudya zosasunthika mkati mwake malinga ngati thumba liri losindikizidwa. Inde, mutatsegula matumba, nitrogen imathawa ndipo imachotsedwa ndi mpweya wokhazikika pafupifupi 20 peresenti ya oksijeni. Izi zikutanthauza kuti chakudya chamkati sichingatetezedwe ndipo chidzayamba kuwonongeka ndipo mafuta kapena mafuta adzayamba kupita.
Mukhoza kusunga mwatsatanetsatane mwa kusunga phukusilo ndi zomangira kapena zojambulazo, kapena poyika chakudya mu chidebe chotsitsimutsa ndikuchiika mu furiji, koma ndibwino kuti mudye zakudya zomwe mumakhala nazo nthawi yayitali.
