He whakamārama poto mō te pauna maha-upoko, te kaupapa hoahoa, te tatau me te tauira tono o ngā tawhā matua o te mahi

Kaituhi: Smartweigh– Taumaha Upoko Maha

Ko te pauna maha-upoko (Te Ngaronga-i-te-Taumaha) he momo taputapu pauna tātari tauanga. Ko te kaupapa matua, ka whakamahia te pauna maha-upoko mō te tukanga pauna tonu hihiri, ka taea te kawe i ngā rauemi mata me whāngai tonu. Ko te pauna me te mahi tātari tauanga, ā, kei reira te rere katoa o ngā rauemi mata me te whakaatu i ngā mōhiohio rere katoa. Ko te tikanga, he pūnaha pauna raraunga pumau, e whakamahi ana i te hangarau pauna o te tauine peke raraunga pumau, ā, e whakamahi ana i te pūoko pauna hei pauna i te peke. Heoi, i roto i te papa whakahaere o te pauna maha-upoko, me tatau te taumaha kupenga i ngaro i ia wā o te tauine peke kia whiwhi ai i te rere katoa o ngā rauemi mata.

Ko te Pikitia 1 he tirohanga mahere o te kaupapa o te pauna maha-upoko. He whakaahuatanga poto o te pauna maha-upoko, te kaupapa hoahoa, te ine me te whakamahinga o ngā tawhā matua o te mahi me tōna take whakamahinga. Pikitia 1. Ko te mahere matua o te pauna maha-upoko. Ko te Pikitia 1 he hoahoa kauwhata o te hanganga o te pauna maha-upoko. Ko te tukunga, ina tae ki te taumata rauemi mōrahi, ka kati te takirere tukunga, ā, ka tautokona te pūwero pauna e te pauna maha-upoko. Kia tika ai te pauna, ka honoa ngā taha o runga me raro o te pūwero pauna kia rite ki te awa ngohengohe, ki te tomokanga me te putanga rānei, kia kore ai e whakamahia te taumaha kupenga o mua me muri, o ngā mīhini me ngā taputapu maui me te matau me ngā rauemi mata ki runga i te pūwero pauna.

Ko te taha matau o te Pikitia 1 he tirohanga mahere o te tukanga katoa o te whāngai tonu. He pūnaha huringa tō te tukanga katoa o te whāngai tonu (e toru ngā huringa e whakaaturia ana i te pikitia). E rua ngā huringa o ia pūnaha huringa: ina takoto kau te ipu pauna, ka whakatuwheratia te takirere tuku hei tuku i te rauemi, ā, ka piki haere tonu te taumaha kupenga o te rauemi mata i roto i te ipu pauna. Ina tae ki te taumata rauemi mōrahi i te t1, ka kati te takirere tuku. Ka tīmata noa te kawe tīwiri ki te riringi i te rauemi, kātahi ka tīmata te mahi a te pauna maha-upoko; i muri i tētahi wā, i te heke haere tonu o te taumaha kupenga o te rauemi mata i roto i te ipu pauna, ā, ka tae ki te taumata rauemi iti rawa i te t2, ka whakatuwheratia anō te takirere tuku, ā, ko te wā mai i te t1 ki te t2 ko te mahi Whakahau i te wā huringa whāngai; I muri i tētahi wā, ina piki haere tonu te taumaha kupenga o te rauemi mata i roto i te pūwero pauna, ā, ka eke anō ki te taumata mōrahi o te rauemi i te wā t3, ka kati te takirere tuku, ā, ko te wā mai i te t2 ki te t3 te wā huringa mō te tuku anō, me ērā atu. I te wā huringa o te whāngai kaha, ka aroturukitia te ōwehenga tere o te kawe tīwiri i runga i te tere rere inamata hei whakatutuki i tētahi whāngai pumau; i te wā huringa tango anō, ka mau tonu te ōwehenga tere o te kawe tīwiri i te ōwehenga tere i mua tata i te tīmatanga o te wā huringa. Hurihia te whāngai ki te tikanga aroturuki rere rōrahi pumau.

Nā te mea ka whakauruhia e te pauna maha-upoko te pauna hihiri me te pauna raraunga pumau, ā, ka whakauruhia hoki te whāngai kua whakakorea me te whāngai tonu, he ngāwari te hiri i te hanganga, ā, he pai mō te pauna i ngā rauemi mata tino pai pērā i te raima, te paura raima tere, te waro kua paura, te kai, te rongoā, me ētahi atu. Mā te whakahaere taumaha me te whakaranu, ka taea te whakatutuki i te tino tika me te rārangi pauna. 2. Te hiranga o te kaupapa hoahoa o ngā tawhā matua o te mahi a te pauna maha-upoko I te wā e hoahoa ana i te kaupapa o te pauna maha-upoko, me whai whakaaro ki ngā tawhā matua o te mahi pērā i te auau o te tukunga, te nui o te tukunga anō, te kaha o te hopa pauna, me te tere o te tukunga anō, ki te kore e kore e mahi tika te pauna maha-upoko i te mahi. I hokona e tetahi kaihoko he pauna maha-upoko mai i te kaihanga mō te tiaki taputapu i te papaanga mō te tātari āhuatanga. E toru noa iho ngā pūoko pauna 100kg i hokona. I muri i te whakamahinga, i kitea he kore pumau te pūwāhi kore, ā, i ētahi wā kāore te rere katoa e whakaatu i ngā mōhiohio me ētahi atu hapa noa.

I muri i te tukunga atu o ngā tāngata e te kaihanga ki te papaanga, kātahi anō ka mōhio rātou ko te waikawa boric te rauemi mata o te kiritaki, ko te kiato whanaunga he 1510kg/m3, ko te rere katoa mōrahi he 36kg/h anake, ā, ko te rere katoa noa he 21~24kg/h. He iti rawa te rere katoa, ā, e toru ngā pūwāhi tautoko pūtau uta 100kg e whakamahia ana e te hopper.
