| I-UPC § 418.0 / IPC § 410.0 | IAPMO / ICC | Ilawula ubungakanani bemibhobho yokukhupha amanzi, iimfuno zomgibe, ukuthintela ukubuya kwamanzi, kunye nobukhulu bokuphuma kwenkunkuma |
| Umgangatho wesi-2 we-NSF/ANSI | I-NSF yaMazwe ngaMazwe | Imisela ukwakheka kwezinto, ukugqitywa komphezulu, kunye nemigangatho yokwakha umthungo kwizixhobo zeendawo zokutya |
Igama Elisemthethweni: "Isinki Yenkonzo" kunye Nesizathu Sokuba "Isinki Yokumopha" Ibambeke
Iikhowudi zemibhobho kunye nokutya zibiza le ntoisinki yenkonzo: isitya esifakwe ngokusisigxina esisetyenziselwa kuphela ukuzalisa nokuthulula izixhobo zokucoca kunye nokulahla amanzi amdaka. Kwindawo yomsebenzi nakwiikhathalogu zemveliso, isixhobo esifanayo sisoloko sibizwa ngokuba yiisinki yemophu. Elo gama lavela kumsebenzi oyintloko wesixhobo, ukuzalisa nokuhlamba iibhakethi zemophu, kwaye ngoku ligama abasasazi, abalungisi bemibhobho, kunye nabathengi abalisebenzisayo ukukhangela nokucacisa izixhobo. Omabini la magama akhomba kwimveliso enye. Igama elithi “isinki yenkonzo” livela kwimigaqo; elithi “isinki yemophu” liqhuba indlela oyithenga kwaye uyifaka ngayo.
Ikhowudi yokutya ye-FDA § 5-203.13ifuna ukuba iindawo zokutya zibonelele ubuncinane ngesinki enye yenkonzo. Abasebenzi abacoca iimophu okanye abahlamba amalaphu kwisinki yokuhlamba izitya enamagumbi amathathu okanye isinki yokulungiselela ukutya benza ukwaphulwa komthetho okukhulu, nto leyo abahloli abayikhankanyayo ukuze kuthathwe amanyathelo okulungisa ngokukhawuleza.
2. Umgangatho wesi-2 we-NSF/ANSI: Imithetho yezinto zokwakha kunye nolwakhiwo
I-NSF/ANSI Standard 2 (Food Equipment) ichaza imigangatho esezantsi yezinto zokwakha kunye nokuveliswa kwazo naziphi na izixhobo ezikwindawo yokutshiza kwindawo yokutya yeshishini. Isinki ye-mop yentsimbi engagqwaliyo ephethe uphawu lwe-NSF kufuneka ihlangabezane nayo yonke imiqathango engezantsi.
Kutheni uhlobo lwe-304 olungenasici lusisiseko?
Umgangatho wesi-2 we-NSF/ANSI ufuna ukuba iindawo ezikwiindawo zokutshiza zibe bushelelezi, zingabi nazimbobo, kwaye zingamelani nokugqwala. Intsimbi epeyintiweyo, i-zinc egayiweyo, kunye neentsimbi ezifakwe i-thin-gauge zonke aziphumeleli kule mfuneko.
- I-alloy:CacisaUhlobo lwentsimbi engagqwaliyo engu-304(18% ye-chromium, 8% ubuncinci be-nickel). Olu lwakhiwo alunazo izithintelo zokungcoliswa zi-alkaline detergents kunye nee-sanitizers ezisekelwe kwi-chlorine ngamanani aqhelekileyo okunyibilikisa.
