Masiku ano n'zovuta kukhulupirira izi, koma posachedwa, matumba apulasitiki akhala amtengo wapatali komanso wopanda chosowa, ndipo palibe imodzi mwa mitundu yothetsera. Mwamwayi nthawi zina zasintha bwino ndipo pafupi ndi khitchini iliyonse mukhoza kupeza chakudya cha polyethylene kapena polyvinyl chloride filimu. Osocheretsa amayamikira zonse zabwino za nkhaniyi ndikuzigwiritsira ntchito mosamala kwambiri posungira katundu, kutanyamula mapepala osiyanasiyana ndi chakudya chophika. Ndipo zokondweretsa kwambiri zokhudzana ndi filimu yamankhwala zomwe mungaphunzire kuchokera m'nkhani yathu.
Mafilimu opangira zakudya
Choyamba, tiyeni tidziwe bwino ndi heroine ya nkhani yathu yoyandikira. Mafilimu amatha kukhala polyethylene kapena polyvinyl chloride (PVC). Ndipo ngakhale kuti ndi kovuta kuti munthu wodziwa kusiyanitsa wina ndi mzake atangoyang'ana, pali kusiyana kosiyana mu makhalidwe awo. Mmodzi mwa iwo ali ndi mafuta omwe amatsutsa puloteni ya polyethylene kusiyana ndi "kupuma" kwachibale cha PVC. Pankhaniyi, filimuyi yopangidwa ndi timapepala ting'onoting'ono ta polyethylene ingagwiritsidwe ntchito pa chakudya chozizira, mwachitsanzo, ponyamula zitsamba , masamba, zipatso, mkate. Zomwe zili pansi pa zipolopolozi sizidzawonekera pa zotsatira zowononga zachilengedwe ndipo zidzasungiratu katundu wawo m'moyo wonse wa mankhwalawa. Kuyesera kunyamula chinachake mu filimu yopulasitiki ya pulasitiki kudzatha mu fiasco wathunthu: izo zidzangowonongeka ndi kutaya katundu wake woteteza. Osati njira yabwino kwambiri, polyethylene imayendetsedwa ndi dontho lakutali lautali - mufiriji imakhala mwamsanga kukhala mdima ndipo imakhala yopweteka. Koma PVC-filimuyi idzayang'anizana bwino ndi zakudya zotentha ndi zazing'ono, ndipo mbale pansi pake sizidzataya kukongola kwake ndipo sizidzatha. Kuwonjezera pamenepo, sichikusowa mafuta ndi zidulo, zomwe zimapanganso njira yabwino yothetsera mbale zophikidwa mwatsopano. Kuwonjezera apo, kuthekera kwa kupirira kutentha kwakukulu kumatithandiza kugwiritsa ntchito filimuyi ngakhale mu uvuni wa microwave, mwachitsanzo, kuti mupitirize kudya mobwerezabwereza popanda kuchotsa phukusi. Komanso, mafilimu osiyana amenewa ali ofanana kwambiri - zipangizo zonsezi zimatha kutambasula katatu katatu ndipo zimamatira kumbali iliyonse. Zonsezi zimakulolani kuti mutenge pang'onopang'ono katundu wa mtundu uliwonse ndi kukula kwake, osagwiritsa ntchito zida zotsatila chipani chachitatu. Ndipo izo zikhoza kuchitidwa ponse pothandizidwa ndi makina apadera onyamula, ndi kusuntha mpukutu wa filimu ndi dzanja.
Sinthani filimu ya chakudya
Malo apadera pakati pa zipangizo zopangira chakudya ndi kutaya filimu. Khalidwe lake lodziwika ndi luso lotha kugwilitsila nchito kutentha ndi kutenga mawonekedwe a chinthucho. Wapeza ntchito yowonjezereka kwambiri mu gawo la malonda, kumene zakudya zosiyanasiyana zimadzaza mufilimu yotereyi. Pachifukwa ichi, filimuyo imakhalabe yoonekera bwino, choncho wogula ali ndi mwayi onse
Kuwoneka kwa kanema wa zakudya
Standard polyethylene chakudya filimu imapezeka mu makulidwe a 6, 7.5 kapena 8 microns. PVC yowonjezera chakudya, izi zimatha kukhala 8, 9, 10, 12 kapena 14 microns. Posankha makulidwe, muyenera kuganizira mtundu wa zinthu zomwe zidzakumbidwa. Choncho, chifukwa chonyamula zipatso, zipatso, bowa ndi zamasamba, filimu ya PVC yokhala ndi makironi 9 akufunika. Ndipo pofuna kudya nyama, nsomba ndi mapepala osakaniza, muyenera kujambula filimuyi ndi makulidwe a 12-14 microns.
