Kunyamula thupi kunachokera kumayiko otukuka ku Europe ndi United States, ndipo ndiye njira yogawa nyama yatsopano.
Tengani ng'ombe mwachitsanzo, mwaukadaulo, kuyika zomata ndikutenthetsa filimu yapulasitiki yowonekera mpaka kufewetsa, kenako kuphimba ng'ombe yodulidwayo yokhala ndi bokosi la thireyi, vacuum kuchokera pansi, kuti filimu yotenthetsera ndi yofewa imamatira pamwamba pa ng'ombe molingana ndi mawonekedwe ake, komanso amatsatira thireyi bokosi kunyamula ng'ombe, pambuyo kuzirala ndi kupanga, amakhala buku ma CD chinthu.
Tsopano pamsika, mawonekedwe oyikapo amagawidwa mochulukira, zotengera kutentha kwa vacuum, zosungirako zosungira mpweya, ndipo pali zomata izi.
Zochuluka, ndiko kuti, njira yachikhalidwe, zidutswa za ng'ombe zowazidwa m'chombo, zowonekera mumlengalenga;vacuum shrink phukusi, monga ng'ombe kuvala bikini zothina;mpweya woziziritsa mwatsopano ma CD, monga ng'ombe mu anayi-mbali inflatable bokosi;zomata ma CD, monga ng'ombe ndi nyama pansi pa bokosi, bikini lonse.
Mitundu yamapaketi amtunduwu imakhalira limodzi, ndikutengera kusiyanasiyana kwa msika.Zochuluka, zomwe zimadziwikanso kuti ng'ombe yotayirira, yomwe imapezeka m'misika ya alimi, misika yam'mawa, malo ogulitsa katundu wamtengo wapatali, chifukwa palibe ma CD oti alankhule, akuwonekeratu mlengalenga, popanda chotchinga kunja kwa dziko, n'zovuta block zoipitsa, pali zoopsa zachitetezo, koma mtengo ndi wotsika mtengo, womwenso ndi mwayi wake.
Kuyika kwa vacuum shrink, moyo wautali wa alumali, malingana ndi kulongedza kwake, sungani 0-4 ℃ kutentha kwa firiji, nthawi yayitali kwambiri ya masiku 45-60, mbiri yakale yachilendo kwambiri mpaka masiku 90, oyenera kwambiri zidutswa zazikulu za nyama yatsopano. zoyendera mtunda wautali, monga tinthu tating'onoting'ono ta nyama amagwiritsanso ntchito vacuum shrink ma CD, ndalama zopangira ndizokwera kwambiri, chifukwa chake mtengo wake ndiwokwera.
Zopaka zatsopano zokhala ndi gasi, zomwe zimapezeka m'masitolo apamwamba kwambiri kapena m'malo okwera kwambiri a ng'ombe m'masitolo akuluakulu, zimakhala ndi shelufu yayifupi, ndipo malinga ngati zoyikazo sizili bwino ndikusungidwa mufiriji pa 0-4 ℃, nthawi ya alumali ndi nthawi zambiri masiku 5-7, omwe ndi okwera mtengo komanso oyenera kudyedwa ndi banja komanso osayenera kuyenda mtunda wautali wa zidutswa zazikulu za ng'ombe.
Kupaka zomata, moyo wa alumali ndi wamfupi kuposa kusungirako kutentha kwa vacuum, kutalika kuposa kusungirako gasi, pakati pa ziwirizi, malinga ngati choyikacho chili bwino, sungani 0-4 ℃ kutentha kwa firiji, moyo wa alumali nthawi zambiri umakhala masiku 30-35, mpaka masiku 40.Kupaka uku kumapangitsa kuti chinthucho zisawonekere, komanso kuti zitheke, makasitomala amatha kukhudza mawonekedwe, kumva bwino, nthawi za 'ubwenzi'.
Ubwino wa kulongedza zomata, kuwonjezera pa nthawi yayitali ya alumali, yoyenera kufunidwa kwa ogula kuti mukhale mwatsopano;amakhalanso ndi mawonekedwe apamwamba, owoneka, okhudza;poyerekeza ndi ma CD ena, zomata ma CD palibe kukapanda kuleka, palibe madzi padziko laminate, palibe chifunga, kugwedeza sikudzakhudza maonekedwe ndi mawonekedwe a nyama;ndiyosavuta kutsegula, yosavuta kuyipeza;palibe zotsalira zamalire, zinthu zapamwamba (filimu yophimba / zomata) poyerekeza ndi thireyi, kuti mudulidwe bwino, kuchepetsa kwambiri ndalama zopangira, ndi zina zotero, zopindulitsa zambiri.
Zaka zingapo zapitazo, sitolo yakale ya ku Britain ya Marks & Spencer inayambitsa kuyesa kwamtundu wina pa zomata, zotsatira zinasonyeza kuti, poyerekeza ndi zopangira mpweya, nyama ya ng'ombe yomata ndi yochuluka. onunkhira komanso ofewa kwambiri.
