Kupambana kwa Melamine Tableware Yosatentha Kwambiri: Lipoti Loyesa Kugwirizana kwa Zipangizo Zapakati Zakukhitchini M'malesitilanti Ang'onoang'ono

Gulu la asayansi ndi akatswiri amakampani adapanga mbale za melamine zosatentha kwambiri, zomwe zidatsimikiziridwa kudzera mu mayeso ogwirizana ndi zida zapakati pa khitchini. Lipotili likuwonetsa zomwe zapezeka, zomwe zikuwonetsa kupita patsogolo ndi zotsatira zake pa ntchito za malo odyera.1. Mbiri ndi Kufunika Kwake​

Zakudya zachikhalidwe za melamine, zomwe zimagwiritsidwa ntchito pophika chifukwa cha kulimba komanso mtengo wake, zimalephera kutentha kuposa 120°C—zovuta m'makhitchini apakati pogwiritsa ntchito makina ochapira mbale otentha kwambiri, zotsukira nthunzi, ndi ma uvuni. Izi zimayambitsa kupindika, kusintha mtundu, kutulutsa zinthu zoopsa, zoopsa zachitetezo, komanso ndalama zambiri zosinthira.​

Zovala zatsopano zophikira patebulo zimathetsa mavutowa kudzera mu zipangizo zosinthidwa komanso zopangira, zomwe zimatha kupirira kutentha mpaka 180°C. Kutsimikizira bwino kulonjeza kuchepetsa ndalama, chitetezo chowonjezereka, kukonza magwiridwe antchito, komanso njira zosavuta pochotsa zophika zapadera pa kutentha kosiyanasiyana.

2. Miyezo Yoyesera, Zitsanzo, ndi Njira​

2.1 Miyezo Yoyesera​

Kuyesa kunatsatira miyezo yapadziko lonse lapansi: ASTM C518-17, FDA 21 CFR Gawo 177.1460, ISO 22000, ndi NSF/ANSI 51, kuonetsetsa kuti zotsatira zake ndi zodalirika komanso zodalirika pa kutentha, chitetezo, komanso kugwirizana.​

2.2 Zitsanzo za Mayeso​

Zitsanzo zinaphatikizapo zinthu zatsopano za melamine zotentha kwambiri: mbale za mainchesi 10, mbale za ma oz 16, zotengera zosungiramo malita 1, mathireyi a mainchesi 18x12, ndi ziwiya zophikira. Melamine yachikhalidwe yokhala ndi mawonekedwe ofanana imagwiritsidwa ntchito ngati zowongolera. Zitsanzo zonse zinali zatsopano komanso zosagwiritsidwa ntchito.

2.3 Njira Yoyesera​

Poyesedwa m'khitchini yoyeserera yapakati ya labu yovomerezeka, mayesowa adagwiritsa ntchito njira yosiyana pang'ono pa mtundu uliwonse wa zida. Zitsanzo zidachitidwa maulendo 12 (nthawi iliyonse imagwiritsa ntchito sabata imodzi) ndikuwunika kusintha kwa thupi, kukhazikika kwa mankhwala, umphumphu wa magwiridwe antchito, komanso kugwirizana kwa zida.​

3. Zipangizo Zoyesera ndi Zotsatira​

3.1 Makina Otsukira Zitsulo Amalonda​

Pogwira ntchito pa 60-71°C (kutsuka) ndi 82-90°C (kutsuka), zitsanzozo zinakhala ndi ma cycle 100 mu chotsukira mbale cha Hobart AM15V.

Melamine yotentha kwambiri sinali yopindika, sinakanda kwambiri, sinasinthe mtundu ndi tomato sauce/curry, ndipo inapirira kutsukidwa kwa 88°C. Melamine yachikhalidwe inali ndi kupindika kwa 30% pambuyo pa maulendo 50, kusintha kwa mtundu kwambiri ndi maulendo 30, ndipo inasweka ndi 15% pambuyo pa maulendo 100.

3.2 Zoyeretsera Nthunzi​

Pogwira ntchito pa 121-134°C pansi pa kupanikizika, zitsanzozo zinachitidwa maulendo 50 mu Tuttnauer 2540E sterilizer (mphindi 30 pa 121°C/15 psi).​

Melamine yotentha kwambiri sinawononge, sinali ndi kulemera kokhazikika, komanso sinatuluke melamine/formaldehyde. Melamine yachikhalidwe inali ndi kupindika kwakukulu pambuyo pa ma cycle 10, 40% inapitirira kuchuluka kwa melamine yotetezeka ndi ma cycle 5 (80% ndi 20), ndipo pamwamba pake panali matuza/kutuluka.​
3.3 Ma uvuni Otentha Kwambiri​

Zitsanzozo zinasungidwa mu uvuni wa Vulcan VC5GD kwa mphindi 30 (mphindi 30 pa 180°C).

Melamine yotentha kwambiri sinali ndi kupindika, kusweka, kapena kusintha mtundu, yokhala ndi kukana kutentha kwambiri komanso kufalikira kwa kutentha kofanana. Melamine yachikhalidwe inapindika nthawi yomweyo, inasweka ndi 60% pambuyo pa maulendo 5, ndipo inakhala yachikasu kwambiri ndi maulendo 10.​

3.4 Otsuka a Ultrasonic​

Zitsanzo zinachitidwa maulendo 50 (mphindi 15 iliyonse) mu chotsukira cha Branson CPX3800.

Melamine yotentha kwambiri sinawononge kapangidwe kake, sinali yosalala, komanso sinatuluke. Melamine yachikhalidwe inali ndi kuwonongeka pang'ono pamwamba pa mapangidwe osindikizidwa pambuyo pa maulendo 30 ndipo inachepa pang'ono.​

4. Kukhalitsa ndi Chitetezo kwa Nthawi Yaitali​

4.1 Kukhalitsa Kwanthawi Yaitali​

Pambuyo pa miyezi 6 yogwiritsidwa ntchito mongoyerekeza (kutsuka mbale, kuyeretsa, ndi kukhudza chakudya pa kutentha kwa 95°C), melamine yotentha kwambiri inangokanda pang'ono koma kapangidwe kake ndi ntchito yake sizinasinthe. Melamine yachikhalidwe inali ndi 70% yosayenerera kugwiritsidwa ntchito chifukwa cha kupindika, kusweka, kapena kusintha mtundu.​
4.2 Kuwunika Chitetezo​

Mayeso osamukira ndi ma simulants osakaniza chakudya, kusanthula kwa heavy metal, ndi mayeso otulutsa formaldehyde/melamine adawonetsa milingo yonse yochepera malire a FDA/EU, kutsimikizira chitetezo pansi pa mikhalidwe yovuta.

5. Zotsatira Zothandiza​

5.1 Kusunga Ndalama​

Ndi moyo wautali nthawi 3-4 kuposa melamine yachikhalidwe, unyolo wapakati (malo 50) ukhoza kusunga ndalama
​
50,000−100,000 pachaka. Kugwirizana kumachepetsa ndalama zomwe zimagwiritsidwa ntchito pochotsa mbale zapadera.

5.2 Kugwira Ntchito Mwanzeru​

Kugwiritsa ntchito chakudya kuchokera ku kukonzekera mpaka kutumikira kumachotsa kusamutsa chakudya, kuchepetsa nthawi komanso zoopsa za kuipitsidwa. Kukhalitsa kwake kumachepetsa nthawi yosinthira chakudya.​

5.3 Chitetezo cha Chakudya ndi Kusasinthasintha kwa Mtundu​

Kukhazikika kumaletsa kutulutsa zinthu zoopsa panthawi yoyeretsa komanso kumachepetsa kukula kwa mabakiteriya. Maonekedwe okhazikika amasunga chithunzi cha kampani m'malo osiyanasiyana.

6. Malingaliro a Akatswiri​

Chef Maria Rodriguez anati: “Zotsatirazi zikusintha kwambiri—zotengera za patebulo zomwe zimagwira ntchito kuyambira pa chotsukira mbale mpaka chotsukira mbale zimapangitsa kuti ntchito ziyende bwino.” John Chen anawonjezera kuti: “Kusunga chitetezo pamalo otentha kwambiri kumatsimikizira kuti miyezo ndi yolondola komanso kukonza magwiridwe antchito.” Dr. Emily Wong anayamikira “kupambana kwa njira yopangira zinthu modabwitsa ndi umboni wamphamvu woyesera.”​

7. Mapeto ndi Chiyembekezo​

Zotsatira za mayeso zimatsimikizira kuti mbale zatsopano za melamine zimapirira mavuto azamalonda komanso zimakhala ndi chitetezo komanso magwiridwe antchito abwino. Ubwino wake ndi monga kuchepetsa ndalama, kukonza magwiridwe antchito, chitetezo chokwanira, komanso kusasinthasintha kwa mtundu wake.​

Mapulani amtsogolo akuphatikizapo kukulitsa mitundu yosiyanasiyana ya zinthu ndi kuyesa kulimba kwa zinthu zenizeni. Kapangidwe kameneka kakhazikitsa miyezo yatsopano ya zakudya zoperekera zakudya, kupatsa malo odyera ambiri mwayi wopikisana nawo kudzera mukuchita bwino, kuchepetsa ndalama, komanso chitetezo chowonjezereka.​
