Chikwama Chosungiramo Chakudya Chogwiritsidwanso Ntchito Chobwezeretsanso Chikwama Chosungiramo Chakudya Chogwiritsidwanso Ntchito

Matumba opaka vacuum amagawidwa m'matumba owoneka bwino a vacuum ndi matumba opaka a aluminiyamu. Zinthu zopangidwa ndi matumba opaka vacuum ndi zopangidwa ndi PE ndi nayiloni. Nayiloni ili ndi zinthu zabwino zotchinga, imatha kuletsa chinyezi ndi mpweya, ndipo imatha kusunga vacuum kwa nthawi yayitali. Matumba apulasitiki omwe amagwiritsidwa ntchito ndi mapulasitiki wamba. Matumba apulasitiki oterewa ali ndi ma pores pamwamba ndipo sangatsegulidwe ndi vacuum. Ngakhale atapakidwa mosafuna, amatuluka kwa nthawi yayitali, kapena atangopakidwa. Ngati mukufuna kusunga chakudya chatsopano kwa nthawi yayitali, sizingatheke kuchita izi popaka vacuum, chifukwa pamene kuchuluka kwa mpweya m'thumba lopaka ndi kochepera kapena kofanana ndi 1%, liwiro la kukula ndi kuberekana kwa tizilombo toyambitsa matenda lidzatsika kwambiri, ndipo pamene kuchuluka kwa mpweya kuli kochepera kapena kofanana ndi 0.5%, kuchuluka kwakukulu kwa tizilombo toyambitsa matenda kumalepheretsedwa ndikusiya kuchulukana.
Zinthu zofunika kwambiri pa thumba la vacuum la zipper lokhala ndi zisindikizo ziwiri kuchokera ku OK
1) Mapaketi a munthu aliyense payekhapayekha ndi aukhondo kwambiri;
2) Yobwezerezedwanso komanso yosavuta kuyeretsa;
3) Zinthu za PA+PE zoyezera chakudya;
4) Zikakhala zokhuthala, zotsekedwa kawiri komanso zokanidwa, zimakhala zovuta kutulutsa madzi;
5) Kukula kwa chigamba cha nozzle pa thumba la vacuum kungafanane ndi makina ambiri ochapira amanja/amagetsi omwe ali pamsika.
Kuwonjezera pa makhalidwe omwe ali pamwambapa, ilinso ndi kukhazikika kwabwino kwa mankhwala, sigwira ntchito ndi asidi wamba ndi alkali kutentha kwa chipinda, ili ndi mphamvu zina zomangirira ndi kung'ambika kwa makina, kusinthasintha kwabwino; kukana kutentha kochepa, imatha kusintha kuzizira kwa chakudya. Zogulitsazo ndi zosinthasintha komanso zosiyanasiyana, ndipo magwiridwe antchito otseka kutentha ndi abwino kwambiri. PE yokha si poizoni ndipo ili ndi zowonjezera zochepa, kotero imaonedwa kuti ndi zinthu zotetezeka kwambiri zosungiramo zinthu.
Zosakaniza zomwe zapakidwa tsiku ndi tsiku, nyama yankhumba yopanda mafuta, chakudya cha mphaka wopanda mafuta, zipatso zouma, zipatso ndi ndiwo zamasamba zatsopano ndizothandiza kwambiri. Zingagwiritsidwenso ntchito popaka chakudya chozizira. Chifukwa cha kutseka kutentha bwino, chitetezo chaukhondo komanso mtengo wotsika, nthawi zambiri imagwiritsidwa ntchito ngati gawo lotseka kutentha la zinthu zophatikizika, ndipo imagwiritsidwa ntchito kwambiri popaka zakudya zosiyanasiyana.
