Ngokocwaningo, ziningi izinto ezithinta umphumela wokuvala inzalo emathini, njengezinga lokungcoliswa kokudla ngaphambi kokuvalwa inzalo, izithako zokudla, ukudluliswa kokushisa, kanye nezinga lokushisa lokuqala lamathini.
1. Izinga lokungcoliswa kokudla ngaphambi kokuvalwa inzalo
Kusukela ekucutshungulweni kwezinto ezingavuthiwe kuya ekufakweni kokuvalwa kwe-canning, ukudla kuzoba ngaphansi kwamazinga ahlukene okungcoliswa yi-microbial.Izinga lokungcoliswa liphezulu, kanye nesikhathi esidingekayo sokuvala inzalo ngezinga lokushisa elifanayo.
2. Izithako zokudla
(1) Ukudla okusemathinini kunoshukela, usawoti, amaprotheni, amafutha nokunye ukudla okungase kuthinte ukumelana nokushisa kwama-microorganisms.
(2) Ukudla okune-asidi ephezulu kuvame ukuvalwa inzalo emazingeni okushisa aphansi nangesikhathi esifushane.
3. Ukudlulisa ukushisa
Lapho kushisa inzalo yezimpahla ezisemathinini, imodi eyinhloko yokudlulisa ukushisa i-conduction kanye ne-convection.
(1) Uhlobo nokuma kweziqukathi zokufaka amathini
Amathini ensimbi azacile afakwe kuthini adlulisa ukushisa ngokushesha kunamathini engilazi, futhi amathini amancane adlulisa ukushisa ngokushesha kunamathini amakhulu.Umthamo ofanayo wamathini, amathini ayisicaba kunamathini amafushane adlulisa ukushisa ngokushesha
(2) Izinhlobo zokudla
Ukudluliswa kokushisa kokudla okuwuketshezi kuyashesha, kodwa uketshezi lukashukela, i-brine noma i-flavoring liquid izinga lokudlulisa ukushisa nokugxila kwalo liyakhuphuka futhi liyehla.Izinga lokudlulisa ukushisa kokudla okuqinile lihamba kancane.Ukudlulisa ukushisa kwebhulokhi amathini amakhulu kanye nokuqina okusemathinini kuhamba kancane.
(3) Ifomu lebhodwe lokuvala inzalo namakani ebhodweni lokuvala inzalo
Ukuvala inzalo nge-Rotary kusebenza kakhulu kunokuvalwa kwe-static, futhi isikhathi sifushane.Ukudlulisa ukushisa kuhamba kancane ngenxa yokuthi amathini ebhodweni lokuvala inzalo kude nepayipi lokungena lapho izinga lokushisa ebhodweni lingafinyeleli ibhalansi.
(4) Izinga lokushisa lokuqala lekani
Ngaphambi kokuvala inzalo, izinga lokushisa lokuqala lokudla ebhodweni kufanele linyuswe, okubalulekile emathinini angakhi kalula i-convection kanye nokudlulisa ukushisa kancane.
