I mua i te tīmatanga o te mahi a te mīhini, he mea nui te tirotiro āta. Ka tīmata ngā tohunga hangarau mā te tirotiro i te āhua o waho o te taputapu. Ka tohua tonutia ngā tohu o ngā pakaru, o ngā āhua rerekē rānei o te tāke kōne-rua, ā, ka whakakīkīhia ngā wāhanga hononga koretake hei ārai i ngā turuturu rauemi pea, hei tiaki hoki i ngā hapa o te taputapu. Ka tirotirohia te pūnaha korehau, me te āta tirotiro i te taumata hinu o te papu korehau kia tika, ā, ka tirotirohia ngā paipa mō ngā pakaru, ngā aukati rānei. Waihoki, ka tirotirohia te pūnaha whakamahana mō ngā turuturu i roto i ngā paipa hinu kawe wera, i ngā paipa mamaoa rānei, ā, ka whakaūtia te pono o te taputapu whakahaere pāmahana. Hei whakamutunga, ka tirotirohia te pūnaha whakahaere hiko hei whakarite kia mau ngā hononga waea me te tika o ngā pānui taputapu.

Kia mārama katoa i muri i te tirotiro, kua tae ki te wā ki te tīmata i te tukanga whakamaroke. Ka āta whakaurua te rauemi e whakamarokehia ana ki roto i te tāke kōne-rua mā te tomokanga, me te aro nui ki te pupuri i te rōrahi kāore e neke ake i te 60% – 70% o te kaha o te tāke. Mā tēnei ka taea e te rauemi te takahuri noa, ā, ka tutuki ngā hua whakamaroke tino pai. I muri i te hiri pūmau o te tomokanga, ka whakakāhia te motuka hurihuri, ā, ka whakaritea he tere hurihuri, mai i te 5 – 20 hurihanga ia meneti, ā, ka whakaritea kia rite ki ngā āhuatanga ahurei o te rauemi, hei whakaoho i te rauemi.

Kātahi ka huri te pūnaha korehau ki te taputapu, ka āta tangohia te ruma kia tae rā anō ki te taumata korehau e hiahiatia ana, i waenga i te – 0.08MPa me te – 0.1MPa, ā, ka mau tonu. I taua wā anō, ka whakahohehia te pūnaha whakamahana, ā, ka whakatakotoria he pāmahana, ka ata whakatikatikaina i runga i te aro o te rauemi ki te wera, ā, i te nuinga o te wā ka taka ki roto i te awhe 30℃ – 80℃. I te roanga o te mahi whakamaroke, ka āta tirotiro ngā kaiwhakahaere i ngā taputapu, ka aroturuki i ngā tawhā matua pēnei i te tohu korehau, te pāmahana, me te tere hurihuri. Ka tuhia auautia ēnei inenga, ka whakarato i ngā raraunga whai hua hei aromatawai i te pai o te whakamaroke me te mahi a ngā taputapu.

Ina tae te rauemi ki te maroke e hiahiatia ana, ka whakawetohia te pūnaha whakamahana. He mea nui te manawanui i a ngā kaiwhakahaere e tatari ana kia whakamatao te pāmahana o te tāke ki te paepae haumaru, i raro iho i te 50℃, i mua i te whakaweto i te pūnaha korehau. Kātahi ka whakatuwheratia mārire te takirere pakaru hau hei whakataurite i te pēhanga o roto ki te hau. Hei whakamutunga, ka whakatuwheratia te putanga tuku, ā, ka hoki mai te motuka hurihuri ki te ora, ka āwhina i te tango maeneene i te rauemi maroke. I muri i te tukunga, mā te horoi pai i ngā taputapu ka tangohia ngā toenga e toe ana, kia whakarite kia rite, kia rite hoki mō tana mahi whakamaroke e whai ake nei.
