Kafukufuku wa chakudya chofewa chopangidwa m'zitini akutsogoleredwa ndi United States, kuyambira mu 1940. Mu 1956, Nelson ndi Seinberg a ku Illinois adayesedwa kuyesa mafilimu angapo kuphatikizapo filimu ya polyester. Kuyambira mu 1958, US Army Natick Institute ndi SWIFT Institute ayamba kuphunzira chakudya chofewa chopangidwa m'zitini kuti asilikali azigwiritsa ntchito, kuti agwiritse ntchito thumba lophikidwa ndi nthunzi m'malo mwa chakudya chopangidwa m'zitini pankhondo, mayeso ambiri ndi magwiridwe antchito. Chakudya chofewa chopangidwa ndi Natick Institute mu 1969 chinadaliridwa ndipo chinagwiritsidwa ntchito bwino ku Apollo Aerospace Program.
Mu 1968, kampani ya ku Japan yotchedwa Otsuka Food Industry Co., Ltd. imagwiritsa ntchito zinthu zowoneka bwino zosungiramo zinthu zophikidwa ndi curry, ndipo yagulitsidwa ku Japan. Mu 1969, pepala la aluminiyamu linasinthidwa kukhala zinthu zopangira kuti thumbalo likhale labwino, kotero kuti malonda a msika akupitiliza kukula; mu 1970, inayamba kupanga zinthu za mpunga zomwe zinali ndi matumba osungiramo zinthu zophikidwa ndi ...
Chikwama chosinthira cha mtundu wa aluminiyamu chinapangidwa koyamba ndi zigawo zitatu za zinthu zosatentha, chotchedwa "thumba losinthira" (mwachidule RP), thumba losinthira logulitsidwa ndi Toyo Can Company yaku Japan, lomwe lili ndi pepala losinthira la aluminiyamu lotchedwa RP-F (losatentha mpaka 135 ° C), matumba owoneka bwino okhala ndi zigawo zambiri zopanda pepala losinthira la aluminiyamu amatchedwa RP-T, RR-N (losatentha mpaka 120 ° C). Mayiko aku Europe ndi America amatcha thumba ili kuti chidebe chosinthasintha (Flexible Can kapena Soft Can).
Zinthu za thumba la Retort
1. Chikhoza kutsukidwa bwino, tizilombo toyambitsa matenda sitingalowe, ndipo nthawi yosungiramo zinthu ndi yayitali. Chikwama chowonekera bwino chimakhala ndi nthawi yosungiramo zinthu kwa chaka chimodzi, ndipo chikwama chobwezera cha mtundu wa aluminiyamu chimakhala ndi nthawi yosungiramo zinthu kwa zaka zoposa ziwiri.
2. Kulowa kwa mpweya ndi kulowa kwa chinyezi kuli pafupi ndi zero, zomwe zimapangitsa kuti zikhale zosatheka kuti zomwe zili mkati zisinthe mankhwala, ndipo zimatha kusunga ubwino wa zomwe zili mkati kwa nthawi yayitali.
3. Ukadaulo wopanga ndi zida zopangira chakudya cha m'zitini m'zitini zachitsulo ndi mabotolo agalasi zingagwiritsidwe ntchito.
4. Kutseka ndi kodalirika komanso kosavuta.
5. Chikwamacho chikhoza kutsekedwa ndi kutentha ndipo chikhoza kumenyedwa ndi ma notches ofanana ndi V ndi U, omwe ndi osavuta kung'amba ndikudya ndi dzanja.
6. Chokongoletsera chosindikizira ndi chokongola.
7. Ikhoza kudyedwa ikatenthedwa mkati mwa mphindi zitatu.
8. Ikhoza kusungidwa kutentha kwa chipinda ndipo ikhoza kudyedwa nthawi iliyonse.
9. Ndi yoyenera kulongedza chakudya chopyapyala, monga nsomba, nyama, ndi zina zotero.
10. Zinyalala n'zosavuta kuzigwira.
11. Kukula kwa thumba kungasankhidwe mosiyanasiyana, makamaka thumba laling'ono lolongedza, lomwe ndi losavuta kuposa chakudya cha m'zitini.
