Pūwero tīwiri kotahi: he pai mō te rauemi kotahi me te whāngai whānui mō ngā kararehe me ngā heihei.
Mīhini whakaputa tīwiri takirua: e whakamahia whānuitia ana i roto i te hanga kai wai me te kai mōkai he nui te uara tāpiri, pērā i te tuna, te honu, me te kai ika taitamariki, nā te mea he nui ngā utu o ēnei hua e hokona ana i te mākete hei utu i te utu o te hanga hua mā te whakamahi i te hangarau tīwiri takirua; Hei tāpiri, ko ētahi kai wai motuhake, pērā i te kai wai matūriki (me te diameter o te 0.8~1.5mm), te kai wai ngako nui, me te kai he iti te rahinga whakaputa engari he huri tonu te tauira, me whakaputa mā te whakamahi i te mīhini whakaputa tīwiri takirua.
Me mārama ake kāore i te tino mārama ngā rerekētanga o runga ake nei. Hei tauira, e kī ana mātou kia whakamahia ngā tīwiri takirua hei hanga whāngai wai, engari i nāianei he maha ngā kamupene e whakamahi ana i ngā tīwiri takitahi hei hanga whāngai wai. He rerekētanga kei roto i te whakamahinga o ngā mea e rua mō te whāngai wai. I roto i te poto, ki te whakaritea ki te tīwiri kotahi, ko ngā painga o te tīwiri takirua e whai ake nei:
① He whānui ake te urutau o ngā rauemi mata, ka taea te urutau ki te tukatuka i te matotoru teitei, te matotoru iti, te nui o te hinu, te makuku nui, te hinuhinu, ngā rauemi mata tino mākū, me ētahi atu rauemi ka paheke ki te tīwiri kotahi (SSE).
② He iti ake ngā here mō te rahi o ngā matūriki o ngā rauemi mata, ka taea te urutau ki te tukatuka i ngā rauemi mata mai i te paura moroiti ki ngā matūriki paura matotoru me te tukatuka tīwiri kotahi o ngā rauemi me ngā rahi matūriki i waho o te awhe motuhake.
③ He ōrite ake te rere o ngā rauemi i roto i te oko, ā, ka taea te tāpiri i te mamaoa, te wai, me ētahi atu hei whakatutuki i te hua e hiahiatia ana.
④ He pai ake te kounga o roto, o waho hoki o te hua, ka taea ai te whakatutuki i te āhua ōrite tino pai, ā, ka ōrite te hanganga ngota o te rauemi. He maeneene te mata i te wā e tangohia ana. He tino ōrite te āhua o ngā matūriki hua, ā, he pai te ōritetanga.
⑤ He pai ake te hua o te pakari me te whakaōrite, he nui ake i te 95% te nui o te pakari o te māngaro, ā, ka taea e te kai wai tukatuka te pupuri i te pumau i roto i te wai, te ārai i te ngaronga o ngā matūkai o te hua, me te ngāwari ki te nakunaku me te mimiti.
⑥ He nui ake te hua i raro i te mana ōrite. Mā te pai o te mahi whakaranu ka taea te whakakotahi i te wera e whiwhihia ana e te rauemi i te wā tika, ka tere ake te pakeketanga o te rauemi, ka whakaiti i ngā rerekētanga o te pāmahana rauemi, ā, ka whakapai ake i te putanga o ngā hua kua whakaputahia.
⑦ He whānui ake te kanorau me te ngāwari o te urutau o ngā hua, ā, ka taea te tukatuka i ngā kai wai moroiti, ngā hinu nui, te makuku nui, ngā hua piripono teitei, me ngā hua maha-tae, momo hanawiti, me ngā hua āhua motuhake.
⑧ He māmā ake te whakahaere i te tukanga, ā, ka taea te whakarite i te tere o te porotaka kia rite ki ngā hiahia o te hua tukatuka. Nā te āhuatanga horoi-ā-ianō, he tino māmā te horoi, ā, kāore he take ki te wetewete i ngā taputapu i muri i ia tukatuka.
⑨ Ka iti ake te pakaru o ngā wāhanga ngoikore. Ko te whakaaro hē noa ko te iti ake o te pakaru o te tīwiri kotahi. Inaa, i te wā o te tukanga whakaputa tīwiri takirua, nā te pumau o te kawe rauemi me ngā āhuatanga rere rauemi, he iti ake te pakaru o te rauemi i runga i te tīwiri me te ringaringa o roto o te oko i tērā o te tīwiri kotahi. Ahakoa he kotahi te huinga o ngā tīwiri, he iti ake tonu te utu o ngā taputapu i tērā o te tīwiri kotahi.
⑩ He iti ake te utu whakaputa. Nā te pumau o te mahi a te tauira tīwiri takirua, he iti ake ngā utu tīmatanga, he iti ake te para wai me te hau, he iti ake ngā utu mahi, he nui te pai o te whakawhiti wera, he nui te hua, me ngā tohu putanga hiko teitei i roto i te tukanga tukatuka whāngai. Hei tāpiri, he iti hoki te utu o ngā taputapu, ā, he iti ake tonu te utu whakaputa whakamutunga ki te whakataurite ki te tīwiri kotahi.
Nā te maha o ngā painga o te tīwiri takirua ki te tīwiri kotahi mō te whakaputa kai wai, e taunaki ana mātou kia whiriwhiria te mīhini whakaputa tīwiri takirua ina taea e ngā āhuatanga katoa.
Ko ngā whakatūpato hei whai mā te whakamahi i te extruder tīwiri takirua:
1. Te haumaru o te mahi:
-I mua i te whakahaere i te extruder tīwiri takirua, me mōhio koe ki ngā tikanga whakahaere o te taputapu, ngā whakatūpato haumaru, me te whakamahinga o ngā taputapu whakaweto ohorere.
-Me mau ngā kaiwhakahaere i ngā taputapu tiaki e tika ana hei karo i ngā aituā me ngā whara pea i te wā e mahi ana.
-Me whakarite kia haumaru te taiao mahi huri noa i ngā taputapu, ā, kia āraihia hoki ngā aituā pēnei i te paheke me te tukinga.
2. Te tiaki taputapu:
-Me tiaki tonu te mīhini whakaputa tīwiri takirua, tae atu ki te horoi, te whakahinuhinu, te whakakīkī i ngā pūtu, me ētahi atu. Me whakarite kei te pai te mahi a te taputapu.
- Tirohia tonutia ngā wāhanga e ngāwari ana te pakaru pērā i ngā tīwiri, ngā whakakā, me ngā huihuinga, ā, whakakapia i te wā tika kia pai ai te mahi a te taputapu.
-Te whakawhanake i ngā mahere tiaki e tika ana i runga i te auau o te whakamahinga o ngā taputapu me te taiao mahi kia mau tonu ai te mahi a ngā taputapu mō te wā roa.
3. Te urutau o ngā rauemi mata:
-He nui ngā rauemi mata e hiahiatia ana mō ngā mīhini pupuhi tīwiri takirua, ā, he rerekē ngā tawhā tukanga pupuhi me ngā tikanga whakahaere mō ngā rauemi mata rerekē.
-I te wā e whiriwhiri ana i ngā taputapu, me whakarite kia tika te tauira me ngā whakaritenga o ngā taputapu mō te hangarau tukatuka e hiahiatia ana i runga i ngā āhuatanga o ngā rauemi mata me ngā whakaritenga tukatuka.
4. Te whakahaere pāmahana me te tere:
-He mea nui ngā tawhā pāmahana me te tere hurihuri e pā ana ki te pānga tukatuka o te extruder tīwiri takirua, ā, me whakarite me te whakahaere tika.
-Me whakarerekē te whakahaere pāmahana kia rite ki ngā rauemi mata me ngā whakaritenga tukatuka rerekē. Tērā pea ka nui rawa te pakari, te tahunga rānei o ngā rauemi mata i te pāmahana nui rawa, ka pā ki te kounga o te hua.
-Me whakarerekē anō hoki te whakahaere i te tere hurihuri i runga i ngā rauemi mata me ngā whakaritenga tukatuka. Tērā pea ka pā te tere hurihuri teitei, iti rānei ki te pānga tukatuka me te kounga o te hua.
5. Te whakahaere i te rahinga rauemi me te tukanga:
-Me whakarerekē te whakahaere i te rahinga o ngā rauemi kia rite ki ngā whakaritenga o ngā taputapu me ngā āhuatanga o ngā rauemi mata. Mā te nui rawa o ngā rauemi ka ārai pea i ngā taputapu, engari mā te iti rawa o te rahinga o ngā rauemi ka whakaiti i te pai o te tukatuka.
-Ko te whakahaere i te tukanga me whakarite i tētahi whakaritenga whaitake mō te whāngai me te tukunga o ngā rauemi mata, kia rite ai te tohatoha o ngā rauemi mata me te tukunga noa o te putanga, me te karo i ngā āhuatanga aukati me te whakaranu.
6. Te horoi me te akuaku:
-Mēnā kei te whakamahi koe i tētahi mīhini whakaputa tīwiri takirua, me aro nui ki te horoi me te whakahaere i te akuaku o ngā taputapu, ā, me horoi auau i ngā toenga me te puehu i roto i ngā taputapu hei ārai i te poke whakawhiti me te tipu o ngā huakita.
