Mfundo zofunika kuzidziwa posankha matumba a chakudya ozizira

1. Ukhondo: Kuchokera pachitetezo, zida zonyamula zomwe zimalumikizana mwachindunji ndi chakudya, monga matumba apulasitiki.Chifukwa cha matumba oundana a zakudya ndi kayendetsedwe ka kayendetsedwe kake, nthawi zambiri zimakhala zovuta kuonetsetsa kuti ndondomeko yonseyi ili m'malo otentha otsika, makamaka panthawi ya mayendedwe ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka anthu. nthawi.Ngati zinthu sizikudutsa, n'zosavuta kuswana mabakiteriya.Palibe kusiyana kwakukulu pamawonekedwe pakati pa kulongedza kopangidwa ndi zinthu zobwezerezedwanso kapena zida zamafakitale ndi kulongedza zopangidwa ndi zida, koma zikagwiritsidwa ntchito, zitha kuvulaza thanzi la munthu chifukwa cha mapulasitiki ochulukirapo ndi zinthu zina.
2. Kukana kuzizira: Matumba a zakudya zozizira nthawi zambiri amasungidwa ndi kufalitsidwa pa kutentha kwa -18 ° C kapena kutsika, makamaka zakudya zina zozizira ndi ma tray.Popanga, chakudya ndi thireyi nthawi zambiri zimazizidwa mwachangu mpaka pansi -30 ° C mpaka kutentha kwazinthu kumakhala pansi pa -18 ° C, kenako kumapakidwa.Pamene kutentha kwadzidzidzi kumatsika, mphamvu yamakina ya thumba lazakudya lozizira kwambiri imachepa, zomwe zimapangitsa kuti thumba lachikwama lachisanu likhale lolimba.Kuphatikiza apo, zakudya zoziziritsa kukhosi zimakumana ndi zoopsa zosiyanasiyana zachilengedwe monga kugwedezeka, kugwedezeka, komanso kupanikizika panthawi yamayendedwe ndi mayendedwe.Kuphatikiza apo, zakudya zoziziritsa kukhosi monga dumplings ndi dumplings zimakhala zovuta pakutentha kotsika.Ndikosavuta kupangitsa kuti thumba loyikamo liwonongeke.Izi zimafuna zida zonyamula ndi ntchito yabwino yotsika kutentha.

3. Kukaniza kwamphamvu: Matumba oundana amawonongeka mosavuta ndi mphamvu zakunja panthawi yoyendetsa, kutsitsa ndi kutsitsa ndikuyika mashelufu.Pamene kutsutsa kwa thumba la phukusi kumakhala kovutirapo, n'kosavuta kuthyola thumba ndikutsegula thumba, zomwe sizimangokhudza maonekedwe a mankhwala opakidwa, komanso zimawononga chakudya mkati.Kukaniza kwa matumba a zakudya zozizira kumatha kutsimikiziridwa ndi kuyesa kwa pendulum.

Matumba azakudya owumitsidwa pamsika amatha kugawidwa m'matumba akusanjikiza amodzi, matumba ophatikizika, ndi matumba onyamula amitundu yambiri.Pakati pawo, matumba onyamula zakudya osanjikizana osanjikizana, ndiye kuti, matumba a PE oyera, amakhala ndi zolepheretsa ndipo amagwiritsidwa ntchito kwambiri ponyamula zipatso ndi masamba;mapulasitiki ofewa ophatikizika ndi abwino kwambiri polimbana ndi chinyezi, kuzizira, komanso kukana kubowola;ndi matumba angapo wosanjikiza co-extrusion matumba Frozen chakudya amapangidwa ndi kusungunula-extruding zopangira monga PA, PE, PP, PET, EVOH, etc., ndi ntchito zosiyanasiyana, nkhonya akamaumba, ndi pawiri ozizira.The ma CD ntchito ali chotchinga mkulu, mphamvu mkulu, mkulu ndi otsika kutentha kukana, etc. Wabwino makhalidwe.
