Kuumitsa nyama mufiriji ndi njira yothandiza komanso yasayansi yosungira nthawi yayitali. Mwa kuchotsa madzi ambiri, imaletsa bwino ntchito ya mabakiteriya ndi ma enzyme, ndikuwonjezera nthawi yosungira nyama. Njirayi imagwiritsidwa ntchito kwambiri m'makampani ogulitsa chakudya, maulendo akunja, komanso malo osungira zinthu zadzidzidzi. Nazi njira ndi zinthu zina zofunika kuziganizira pankhaniyi:
1. Kusankha Nyama Yoyenera ndi Kukonza
Kusankha nyama yatsopano komanso yabwino kwambiri ndiye maziko a kuumitsa bwino mufiriji. Ndikoyenera kugwiritsa ntchito nyama yokhala ndi mafuta ochepa, monga bere la nkhuku, ng'ombe yopanda mafuta, kapena nsomba, chifukwa mafuta amatha kusokoneza njira yowumitsa ndipo angayambitse kusungunuka kwa okosijeni panthawi yosungira.
Kudula ndi Kukonza:
Dulani nyama m'zidutswa tating'onoting'ono tofanana kapena tinthu tating'onoting'ono kuti malo ozungulira awoneke bwino, zomwe zimathandiza kuti iume msanga.
Pewani kudula zidutswa zokhuthala kwambiri (nthawi zambiri zosapitirira 1-2 cm) kuti muonetsetse kuti chinyezi chamkati chachotsedwa bwino.
Zofunikira pa Ukhondo:
Gwiritsani ntchito mipeni yoyera ndi matabwa odulira kuti musaipitse zinthu zina.
Tsukani pamwamba pa nyama ndi mankhwala oyeretsera zakudya ngati pakufunika, koma onetsetsani kuti mwatsuka bwino musanagwiritse ntchito zina.
2. Gawo Lozizira Lisanayambe
Kuwumitsa musanayambe kuzizira ndi gawo lofunika kwambiri pakuumitsa mufiriji. Cholinga chake ndikupanga ma crystals a ayezi kuchokera ku madzi omwe ali mu nyama, ndikukonzekeretsa kuti igwiritsidwe ntchito pambuyo pake.
Mikhalidwe Yozizira:
Ikani zidutswa za nyama pa thireyi, kuonetsetsa kuti pali malo okwanira pakati pawo kuti zisamamatire.
Ikani thireyi mufiriji yokhazikika pa -20°C kapena kutsika mpaka nyama itazizira kwathunthu.
Zofunikira pa Nthawi:
Nthawi yoziziritsira isanayambe kuzizira imadalira kukula ndi makulidwe a zidutswa za nyama, nthawi zambiri zimayambira maola 6 mpaka 24.
Pa ntchito zamafakitale, zida zoziziritsira mwachangu zingagwiritsidwe ntchito kuti ziziziritse mwachangu.
3. Njira Yowumitsa ndi Kuzizira
Chowumitsira chozizira ndicho chida chofunikira kwambiri pa gawoli, pogwiritsa ntchito malo opumira mpweya komanso kuwongolera kutentha kuti makristalo a ayezi azitha kusungunuka mwachindunji.
Kutsegula ndi Kukhazikitsa:
Ikani zidutswa za nyama zomwe zasungidwa kale mufiriji pa thireyi ya chowumitsira chozizira, kuonetsetsa kuti zikufalikira mofanana.
Poyamba ikani kutentha kwa madigiri 10 mpaka 20 Celsius pansi pa malo opumira kuti zitsimikizire kuti zinthuzo zikusungidwa mufiriji yonse.
Gawo Losasinthika:
Mukakhala ndi mphamvu yochepa, pang'onopang'ono kwezani kutentha kufika pa -20°C mpaka 0°C. Izi zimatsimikizira kuti makhiristo a ayezi amasanduka nthunzi ya madzi mwachindunji ndipo amachotsedwa.
Gawo Lachiwiri Louma:
Kwezani kutentha kufika pamlingo wapamwamba kwambiri kuti chinthucho chichotse chinyezi chotsala.
Ntchito yonseyi ingatenge maola 20 mpaka 30, kutengera mtundu wa nyama.
4. Kusungira ndi Kuyika
Nyama youma mufiriji imakhala yosalala kwambiri, choncho njira zomangira ndi kusungira ziyenera kutsatiridwa.
Zofunikira pa phukusi:
Gwiritsani ntchito matumba otsekedwa ndi vacuum kapena ma CD a aluminiyamu kuti muchepetse kukhudzana ndi mpweya ndi chinyezi.
Onjezani mankhwala oyeretsera chakudya mkati mwa phukusi kuti muchepetse chinyezi.
Malo Osungira Zinthu:
Sungani pamalo ozizira komanso ouma, kutali ndi dzuwa lachindunji komanso kutentha kwambiri.
Ngati zinthu zilola, sungani nyama yopakidwa mufiriji kapena mufiriji kuti ipitirize kukhala ndi moyo wautali.
Ngati mukufuna kudziwa zambiri zaMakina Oumitsira Ozizirakapena muli ndi mafunso aliwonse, chonde musazengereze kuyankhaLumikizanani nafeMonga wopanga makina owumitsira makina oziziritsa, timapereka zinthu zosiyanasiyana, kuphatikizapo mitundu yapakhomo, ya labotale, yoyeserera, ndi yopangira. Kaya mukufuna zida zogwiritsidwa ntchito kunyumba kapena zamafakitale akuluakulu, tikhoza kukupatsani zinthu ndi ntchito zabwino kwambiri.
