He mea nui ki te whakaiti i te kai ote patupatuoumu.Ko nga mahi noa ko:
1. Whakamahia te puna wera whaitake
Nga whakaipoipowhakawera kora e whakamahia nuitia he totoka, paura, wai, hau me etahi atu momo.Ko te wera totoka he waro;Ko te wahie paura he waro koriri;Ko nga kora wai he hinu taumaha me te diesel mama;Ko nga kora hau he hau maaori, he hinu hinu me te hau.Ko te nuinga o nga kaihanga ka whakamahi i te hau maori, a ko etahi ka whakamahi i te hau hinuhinu liquefied, hau waro, engari ka whakamahia ano e etahi kaihanga te hinu taumaha, te hinu diesel mama.
2. te whakamahi i te oumu whakawera matatau
Ko te momo whakahou mamati te tere tere o te wera me te hangarau whakahaere me te tuku wahie tonu te momo whakahiato mo te whakakorikori me te hangarau whakahaere e whakamahia ana i roto i te oumu whakawera hau mo nga waatea mewhakangao.Ka whakatauritea ki te kaitahu tere tere + te aratau whakawera preheater hau, ka eke ki te 50% te tere o te penapena hiko, ka whakahaeretia te taurite o te pāmahana oumu i waenga i te ± 10 ℃ i te wa e whakamahia ana ki te oumu whakawera teitei;te tere whakaora pūngao he ki runga ki te 30-50% me te mana o te oumu pāmahana ōritetanga i waenganui i ± 5 ℃ ina tono ki te reo me te iti pāmahana wera oumu maimoatanga.

3. te whakamahi o te tukanga uta rauemi wera
Ko te oumu uta rauemi wera he mehua whakaora kaha mo te whakamahananga pupuhi nui, ara, ko te ingot rino i ringihia mai i te awheawhe hanga maitai ka haria tika ki te awheawhe whakawera mo te whakamahana me te kore whakamatao, a ko te pāmahana oumu kei te nuinga o te waa kei runga ake i te 600 ℃.Ka whakatauritea ki te oumu whakamahana makariri, ka taea e ia te whakaora i te kaha ma te 40-45%, te whakaora i te wa whakawera, te whakaiti i te maha o nga whirihoranga whakamahana, me te whakapai ake i te pai o te whakaputa.
4. Hangarau whakaora wera ururua
Ko te pāmahana o te hau rewharewha i tukuna mai i te oumu wahie he teitei ki te 600-1200 ℃, a ko te wera i tangohia e 30-70% o te wera katoa.Ko te whakaora me te whakamahi i tenei waahanga o te wera he huarahi nui ki te whakaora i te kaha i roto i te awheawhe hanga.I tenei wa, ko te huarahi matua ki te whakamahi ko te whakamahi i te whakamahana, ara, te whakamahi i te wera ururua o te hau rewharewha hei whakamahana i te hau ngiha me te wahie hau.Na te kaha o te whakatairanga o te penapena hiko me te whakahekenga o te tukunga, ko te whakaora tuarua me te whakamahi i te hangarau wera para ka kaha ake te whakamahi i roto i te umanga hangai.
