Ko te whakaranu tētahi o ngā mahi tino nui, tino uaua hoki o te tukatuka rapa. Ko tētahi hoki o ngā mahi e tino pāngia ana e ngā rerekētanga kounga. Ka pā tika te kounga o te ranunga rapa ki te kounga o te hua. Nō reira, he mea tino nui kia pai te whakaranu rapa.
Hei kaiwhakaranu rapa, me pēhea te mahi pai i te whakaranu rapa? Ki taku whakaaro, hei tāpiri atu ki te tino mōhio ki ngā mōhiotanga e tika ana mō ia momo rapa, pērā i ngā āhuatanga whakaranu me te raupapatanga o te inenga, me mahi kaha, me whakaaro nui, me whakaranu rapa me te ngākau nui. Mā tēnei anake ka pai ake te tohungatanga o te kaiwhakarewa rapa.
Hei whakarite i te kounga o te rapa i konatunatua i te wā o te tukanga whakaranu, me mahi ēnei mahi:
1. Me whakaranu katoa ngā momo kai katoa, he iti te horopeta engari he nui te pānga, kia ōrite te whakaranu, ki te kore ka wera te rapa, ka kore rānei e maoa te whakamomona.
2. Me whakahaere te whakaranu i runga anō i ngā ture o te tukanga whakaranu me te raupapa whāngai.
3. Me tino whakahaere te wā whakaranu, kaua hoki e roa rawa, kaua hoki e poto rawa. Mā tēnei anake ka taea te whakamana i te ngāwari o te rapa kua whakaranua.
4. Kaua e maka atu te nui o te pango waro me ngā whakakī, engari me whakamahi katoa. Ā, horoia te paepae.
He pono, he maha ngā āhuatanga e pā ana ki te kounga o te rapa whakakotahi. Heoi, ko ngā āhuatanga motuhake ko te marara koretake o te matū whakakotahi, te hukapapa, te werawera, me ētahi atu, ka kitea ā-kanohi.
Te marara kore taurite o te matū whakaranu Hei tāpiri atu ki ngā matūriki matū whakaranu i runga i te mata o te matū rapa, tapahia te kiriata ki te maripi, ā, ka puta mai ngā matūriki matū whakaranu o ngā rahi rerekē i runga i te wāhanga whakawhiti o te matū rapa. Ka whakaranua te matū kia ōrite, ā, ka maeneene te wāhanga. Ki te kore e taea te whakaoti i te marara kore taurite o te matū whakaranu i muri i te whakamahine maha, ka paraia te rapa roera. Nō reira, me tino piri te mīhini whakaranu rapa ki ngā ture tukanga i te wā e mahi ana, ā, i ētahi wā, tangohia te kiriata mai i ngā pito e rua me waenganui o te roera kia tirohia ai mēnā kei te marara ōrite te matū whakaranu.
Ki te kore te hukapapa e pā ki te hoahoa o te ranunga, ko te take o tēnei ko te kore tika o te raupapa o te inenga i te wā e whakaranua ana, te kore ōrite rānei o te ranunga me te whakakotahitanga o te matū whakaranu. Nō reira, me tino whakahaere te tukanga whakaranu kia kore ai e puta ēnei āhuatanga.
Ko te werawera tētahi o ngā raruraru nui o te tukanga whakaranu. I muri i te werawera o te rauemi rapa, ka puta he matūriki rapa kua tunua ki te mata, ki te wāhanga o roto rānei. Mena he iti te werawera, ka taea te whakatau mā te tikanga angiangi. Mena he nui te werawera, ka paraia te rauemi rapa. Mai i te tirohanga a ngā āhuatanga tukanga, ko te werawera o te ranunga rapa te mea nui e pāngia ana e te pāmahana. Mena he teitei rawa te pāmahana o te ranunga rapa, ka tauhohe te rapa mata, te kaihoko whakapūkara me te whakateretere i te wā whakaranu, arā, te werawera. I raro i ngā āhuatanga noa, mena he nui rawa te nui o te rapa i te wā whakaranu, ā, he teitei rawa te pāmahana o te roera, ka piki ake te pāmahana o te rapa, ka hua ake he werawera. Ko te tikanga, ki te kore e tika te raupapa whāngai, ka ngāwari hoki te werawera i te tāpiritanga o te kaihoko whakapūkara me te whakateretere i te wā kotahi.
Ko te rerekētanga o te pakeketanga he mea nui anō hoki e pā ana ki te kounga o te rapa. He maha ngā wā ka konatunatua ngā rapa o te pakeketanga kotahi ki ngā pakeketanga rerekē, ā, ko ētahi he tawhiti rawa te tawhiti. Ko te take nui o tēnei ko te kore taurite o te ranunga o te rapa me te koretake o te horapa o te matū whakaranu. I taua wā anō, mā te tāpiri iti iho, nui atu rānei o te waro pango ka puta he rerekētanga o te pakeketanga o te rapa. I tētahi atu taha, mā te taumaha hē o te matū whakaranu ka puta he rerekētanga o te pakeketanga o te rapa. Pērā i te tāpiri o te matū whakamomona me te waro pango whakateretere, ka piki ake te pakeketanga o te rapa. Ka nui ake te taumaha o te whakangawari me te rapa mata, ā, ka iti iho te waro pango, ā, ka iti ake te pakeketanga o te rapa. Ki te roa rawa te wā whakaranu, ka heke te pakeketanga o te rapa. Ki te poto rawa te wā whakaranu, ka whakapakeke te matū. Nō reira, kaua te wā whakaranu e roa rawa, e poto rawa rānei. Ki te roa rawa te whakaranu, hei tāpiri atu ki te hekenga o te pakeke o te rapa, ka heke te kaha kume o te rapa, ka piki ake te roa i te wā whati, ā, ka heke te ātete ki te koroheketanga. I taua wā anō, ka piki ake te kaha o te mahi a ngā kaiwhakahaere, ā, ka pau te pūngao.
Nō reira, ko te mea anake e hiahiatia ana mō te whakaranu ko te kaha ki te horapa katoa i ngā momo matū whakaranu ki roto i te ranunga rapa, me te whakarite hoki i ngā āhuatanga ā-tinana me ngā āhuatanga ā-pūkaha e hiahiatia ana me ngā whakaritenga o te calendering, te extrusion me ētahi atu mahi tukanga.
Hei kaiwhakaranu rapa matatau, ehara i te mea he kaha te whakaaro o te kawenga anake, engari me mōhio hoki ki ngā momo rapa mata me ngā rauemi mata. Arā, ehara i te mea ko te mārama ki ā rātou mahi me ō rātou āhuatanga anake, engari me taea hoki te whakahua tika i ō rātou ingoa me te kore tapanga, inā koa mō ngā matū he rite te āhua. Hei tauira, ko te konupora waikura, te hauota waikura me te konupūmā hauwaiwai, te waro pango ātete-mau, te waro pango tere-whakaputa me te waro pango whakapakari-haurua, tae atu ki te nitrile-18 o te whare, te nitrile-26, te nitrile-40 me ētahi atu.
