Chipinda chozizira cha nyama ya nkhumba
Kumvetsetsa bwino njira zoyendetsera chipinda chozizira cha nyama kaya ndi chisanu kapena chozizira, ndikofunikira ngati mukufuna zokolola zatsopano, zokoma komanso zotetezeka momwe mungathere.
Mabakiteriya owopsa amayamba kukhala mu nyama yaiwisi kuyambira pomwe nyama imaphedwa, zomwe zimapangitsa kuti kusungako kukhale kovuta kwambiri.Ngati mukufuna kapena mukufuna kutalikitsa moyo wa nyama yanu kwa nthawi yayitali momwe mungathere, ndikofunikira kuti muzitsatira njira zotetezeka zosungirako.
Nthawi zambiri kutentha kumatsika pansi -18 ℃, kuzizira kwa chakudya kunali kwakukulu, tizilombo tating'onoting'ono ndi michere inasiya kusuntha ndikukula, ndipo makutidwe ndi okosijeniwo anali wodekha kwambiri.Choncho, chakudyacho chikhoza kusungidwa kwa nthawi yaitali ndipo chimakhala ndi khalidwe lozizira kwambiri.Kuwonjezera apo, chakudya chachisanu chimafunanso kuti kutentha kwa m’nkhokwe kukhale kokhazikika.Kusinthasintha kwa kutentha kumapangitsa kuti chakudya chiwonongeke.
Nyama ozizira chipinda zimagwiritsa ntchito ozizira processing nyama mitembo monga nkhumba, ng'ombe, ndi nkhosa.
1, Chipinda chozizirirapo
Kuzizira kwa madzi a nyama ndi -0.6 ~ -1.2 ℃.Kutentha kwa nyama ikaphedwa ndi pafupifupi 35 ℃, imatumizidwa kuchipinda chozizira.Kutentha kwachipinda komwe kunapangidwira kumakhala pafupifupi 0 ~ -2 ℃.Kutentha kwa nyama kumachepetsedwa kufika 4 ℃ m'chipinda chozizira.Chifukwa cha kutentha pang'ono ndi kutentha kwa mpweya, kuonjezera kuthamanga kwa mpweya kungapangitse kuzizira.Komabe, kutsika kwamphamvu kwambiri kwa mpweya sikungawonjezere kuzizira poyerekeza ndi nthawi yomweyi ya chaka chatha, koma kudzawonjezera kutayika kowuma komanso kugwiritsa ntchito mphamvu kwa nyama.Choncho, pozizira, liwiro la mphepo m'chipinda chonyamula katundu m'chipinda chozizira ndi loyenera kuti lisapitirire 2m / s, ndipo nthawi zambiri pamwamba pa 0.5m / s amagwiritsidwa ntchito.Nthawi yozungulira mpweya ndi 50 ~ 60 nthawi / h, ndipo nthawi yozizira ndi 10 ~ 20h.Avereji youma thupi kudya pafupifupi 1.3%.
2, Kuzizira processing
A, Kutentha ndi -10 ~ -15 ℃, kuthamanga kwa mpweya ndi 1.5 ~ 3m / s, ndipo nthawi yozizira ndi 1-4h.Mtengo wapakati wa enthalpy wa nyama panthawiyi ndi pafupifupi 40kj / kg, zomwe zimapangitsa kuti pamwamba pa nyama ikhale yosanjikiza ya ayezi.Sikuti amachepetsa kumwa kowuma, komanso kumathandizira kuzizira (kutentha kwa madzi oundana ndi nthawi 4 kuposa madzi).
B, Kutentha kwa chipinda chozizira ndi pafupifupi -1 ℃, kuthamanga kwa mpweya ndi 0.5 ~ 1.5m / s, ndipo nthawi yozizira ndi 10 ~ 15h, kotero kuti kutentha kwa pamwamba kumawonjezeka pang'onopang'ono ndipo kutentha kwamkati kumachepa pang'onopang'ono, kotero kuti kutentha kumachepa. thupi limakhala bwino mpaka kutentha kwapakati kumafika 4 ℃.Nyama yoziziritsidwa ndi njirayi imakhala ndi mtundu wabwino, fungo, kukoma ndi kukoma mtima, zomwe zimafupikitsa nthawi yozizirira ndikuchepetsa kuuma kwa 40% mpaka 50%.Chotsatirachi chikusonyeza ndondomeko zinthu mofulumira kuzirala kwa nyama.
