Tiack okwera kwambiri shyna pvdc shreation roll roll yapangidwa ndi pvdc / per. Ili ndi mpweya wabwino komanso mpweya wotchinga zinthu, kuwonekera bwino komanso gloss, komanso kupumula kwambiri kukana. Ndi nyama yatsopano komanso yokonzedwa, tchizi, nsomba loin etc.
Pansipa pali kutentha magwiridwe antchito :
1. Khazikitsani kutentha koyenera pamakina a vacuum ndi msewu wamadzi otentha;
2. Ikani filimu ya PVDC SAMNCH pa bar yosindikiza. Onetsetsani kuti malonda sakutentha kwambiri (ndi nthunzi) komanso kuipitsidwa pang'ono kuti atsimikizire kuti ali ndi alumali atakhala nthawi yayitali. Unikani kuti palibe makwinya padera lopinga kuti mupewe kusweka;
3. Onetsetsani kuti malonda sanasunthidwe pansi pa filimu ya PVDC, ndipo malo a Chisindikizo ndi oyera kwathunthu;
4. Siyani malo pafupifupi 5cm pakati pa zopangira ndi chosindikizira. Izi ndikuwongolera vacuum mphamvu, komanso kulola kuti chipinda chikhale chowonjezera pambuyo pozizira (chopanda zowuma);
5. Ikani vacuum yolumikizidwa ndi madzi m'masekondi 1-2.
Chifukwa Chomwe Timatsikira :
1. Sinthani zowoneka bwino, kudzutsa kugulitsa apilo;
2. Anachotsa zikwangwani ndi capillaries, kuchepetsa kutayikira;
3. Kuchulukitsa makulidwe a PVDC yochepetsetsa ya PVDC, imasintha chotchinga cha oxygen, chomwe chidzawonjezera moyo wa alumali , komanso kusintha mphamvu ya filimu ya PVDC;
4. Amakulitsa chidindo;
5. Kanema wa PVDC wonyezimira ali ngati khungu lachiwiri , lomwe lingachepetse kutayika komwe kwayamba ndi PVDC shyna snull.
Mafilimu a PVDC SHANCAN amakhala ndi zotchinga katundu kuti mpweya uzisonkhetse, chinyezi, fungo ndi zina. Cholepheretsa PVDC Skumatifota mafilimu okhala ndi ntchito zosiyanasiyana, monga nyama , nkhuku , nsomba zam'nyanja , ndi mkaka wina, ndi zakudya zina.
Kuphatikiza apo, nkhawa zapadziko lonse lapansi zokhudzana ndi kusinthika, ukhondo komanso chitetezo cha chakudya chikuwonjezekanso, zomwe zikukhudza mafakitale onse. Malamulo aboma amakhudza anthu opanga chakudya kuti azikhala ndi miyezo yapamwamba komanso miyezo. Kugwiritsa ntchito chotchinga kumachepetsa mafilimu a PVDC amatha kuwongolera kuwonongeka kwa chakudya pamlingo wina. Chifukwa chake, ngati njira yopangira chakudya, kufunikira kwa chotchinga mafilimu a PVDC kukukulira.
