Kupu Whakataki mō te Takirere Pūrerehua

Kupu Whakataki:

He takirere pūrerehuanō te whānau o ngā takirere e kiia nei kongā takirere huri-hauwhā. I te wā e mahi ana, ka tuwhera katoa, ka kati rānei te takirere ina hurihia te kōpae kia kotahi hauwhā te hurihanga. Ko te "pūrerehua" he kōpae whakarewa e mau ana ki runga i te tokotoko. Ina kati te takirere, ka hurihia te kōpae kia ārai katoa i te ara. Ina tuwhera katoa te takirere, ka hurihia te kōpae kia kotahi hauwhā te hurihanga kia taea ai te haere o te wai me te kore here. Ka taea hoki te whakatuwhera i te takirere kia tere te rere.

He momo rerekē ngā takirere pūrerehua, ia takirere he rerekē te pēhanga me te whakamahinga. Ko te takirere pūrerehua kore-whakawhiti, e whakamahi ana i te ngāwari o te rapa, ko te iti rawa te whakatauranga pēhanga. Ko te takirere pūrerehua takirua-whakawhiti teitei, e whakamahia ana i roto i ngā pūnaha pēhanga teitei ake, ka wehea mai i te rārangi pokapū o te nohoanga kōpae me te hiri tinana (wehenga kotahi), me te rārangi pokapū o te poka (wehenga tuarua). Ka hangaia he mahi cam i te wā e whakahaerehia ana hei hiki i te nohoanga i waho o te hiri ka iti ake te waku i te mea i hangaia i roto i te hoahoa kore-whakawhiti, ā, ka whakaitihia tōna āhua ki te kakahu. Ko te takirere e pai ana mō ngā pūnaha pēhanga teitei ko te takirere pūrerehua takitoru-whakawhiti. I roto i tēnei takirere ka wehea te tuaka whakapā nohoanga kōpae, e mahi ana ki te whakakore tata i te pā reti i waenga i te kōpae me te nohoanga. Mō ngā takirere takitoru-whakawhiti, he mea hanga te nohoanga ki te konganuku kia taea ai te mīhini kia tutuki ai te kati mirumiru ina pā atu ki te kōpae.

Ngā momo

1. Ngā takirere pūrerehua porowhita– he nohoanga rapa pakari tō tēnei momo takirere, ā, he kōpae whakarewa anō hoki.
2. Ngā takirere pūrerehua takirua-āhua rerekē(ngā takirere pūrerehua mahi-teitei, ngā takirere pūrerehua takirua-taurite rānei) – he momo rauemi rerekē e whakamahia ana mō te nohoanga me te kōpae.
3. Ngā takirere pūrerehua rerekē-toru(ngā takirere pūrerehua takitoru-whakakē) – he hoahoa nohoanga whakakikoruatia, he hoahoa nohoanga whakarewa totoka rānei ngā nohoanga.

Ngā takirere pūrerehua momo-wafer

Tetakirere pūrerehua momo angiangiKua hangaia hei pupuri i tētahi hiri mai i ngā rerekētanga pēhanga e rua-ahu hei ārai i tētahi rerenga whakamuri i roto i ngā pūnaha kua hangaia mō te rere kotahi-ahu. Ka tutuki tēnei mā te hiri piri pūmau; arā, he gasket, he mowhiti-o, he mīhini tika, me tētahi mata takirere papatahi i ngā taha whakarunga me ngā taha whakararo o te takirere.

Takirere pūrerehua momo-tuke

Ngā takirere momo-tukehe whakaurunga miro kei ngā taha e rua o te tinana takirere. Mā tēnei ka taea te tāuta ki roto i tētahi pūnaha mā te whakamahi i ngā huinga pūtu e rua, kāore he nati. Ka tāutahia te takirere i waenganui i ngā flange e rua mā te whakamahi i tētahi huinga pūtu motuhake mō ia flange. Mā tēnei whakatakotoranga ka taea te momotu i tētahi taha o te pūnaha paipa me te kore e whakararuraru i tētahi atu taha.

Ko te takirere pūrerehua momo-pū e whakamahia ana i roto i te ratonga pito mate he iti te pehanga. Hei tauira, ko te takirere pūrerehua momo-pū e mau ana i waenganui i ngā flange e rua he 1,000 kPa (150 psi) te pehanga. Ko te takirere kotahi e mau ana me te flange kotahi, i roto i te ratonga pito mate, he 520 kPa (75 psi) te pehanga. He tino ātete ngā takirere pū ki ngā matū me ngā whakarewa, ā, ka taea te tu atu ki ngā pāmahana tae atu ki te 200 °C, he otinga maha-whakamahinga.

Te whakamahinga i roto i te ahumahi

I roto i ngā ahumahi rongoā, matū, me te kai, ka whakamahia he takirere pūrerehua hei aukati i te rere o ngā hua (totoka, wai, hau) i roto i te tukanga. Ko ngā takirere e whakamahia ana i roto i ēnei ahumahi ka hangaia i runga i ngā aratohu cGMP (te tikanga hanga pai o nāianei). I te nuinga o te wā ka whakakapia ngā takirere pūrerehua e ngā takirere pōro i roto i te maha o ngā ahumahi, inā koa te hinu, nā te iti o te utu me te ngāwari o te tāutanga, engari kāore e taea te 'whakakore' i ngā paipa kei roto ngā takirere pūrerehua mō te horoi.
