Ngā Tuke Kowiri tira Ārai Hauora – Te Kōwhiringa Mā mō ngā Ahumahi Kai me te Rongoā

1. Ngā Whakatakotoranga Hua

• Diameter IngoaDN15–DN300 (1/2”–12”)
• Matotoru o te Pakitara: 1.5–3.0 mm (i runga i te rahi me ngā whakaritenga pēhanga)
• Pūtoro Piko1.5D (radius roa) hei paerewa; ka wātea te radius poto (1D) mēnā ka tonoa
• Whakaotinga Mata:

Ā-roto: Kua whakakanapahia ki te hiko ki te Ra ≤ 0.4 μm (pai ake rānei, tae atu ki te Ra ≤ 0.25 μm mō ngā tono tino parakore)

Waho: He whakaata kua orohia, he paraihe rānei hei whakapaipai i te āhua me te horoi.

• Ngā Momo Hononga: Whakapiri-putanga (BW), rawhi (piri-toru), miro, whakarara rānei
• Ngā Tohu Rauemi:

316L (iti-waro) – He pai ake mō te ātete ki te waikura i roto i ngā taiao waikawa, kei roto rānei he pūhaumāota

304L – He kōwhiringa ōhanga mō ngā tono iti ake te uaua

2. Ngā Painga Matua o te Mahi

Kowiri tira māori Tuke RinoHe maha ngā āhuatanga nui i hangaia mō ngā taputapu ahumahi e wehewehe ana i a rātou mai i ngā taputapu ahumahi paerewa:

• Hoahoa Kore-Rohe-MateHe āhua maeneene, he hononga koretake o roto, kāore he kapiti, he rua, he kokonga koi rānei e kohia ai ngā huakita, ngā toenga rānei.
• Te Horoi Pai RawaHe tino hototahi ki ngā pūnaha Horoi-i-te-Wāhi (CIP) me te Whakahoromata-i-te-Wāhi (SIP). Mā te mata o roto, rite ki te whakaata, ka tere te tango me te whakaoti i ngā toenga hua, ngā kiriata koiora, me ngā kaihoko horoi.
• Te Pono o ngā RauemiHe tino ātete te maitai kore waikura 316L ki te pakaru, te waikura kapiti, me te pakaru o te waikura ahotea, ahakoa te maha o ngā whakamahinga o ngā rongoā horoi kaha (hei tauira, te houra tunutunu, te waikawa hauota, te hauwai waikura).
• Te Pūmautanga o te Wera me te MīhiniKa ātete ki ngā huringa whakamate pāmahana teitei (tae atu ki te 150°C / 300°F me tua atu) ā, ka mau tonu te pumau o te hanganga i raro i te ru wera maha.
• Te Aroturuki me te TiwhiketeKa taea te whai i ia tuke me te tohu tau wera. E tutuki ana ngā hua i ngā paerewa akuaku o te ao, tae atu ki:
  • Ngā Paerewa Hauora 3-A (USA)
  • EHEDG (Rōpū Hangarau me te Hoahoa Ā-Hauora o Ūropi)
  • FDA 21 CFR 177.2600 (ngā rauemi e pā ana ki te kai)
  • ASME BPE (Taputapu Tukatuka Koiora)

3. Ngā Kaupapa Matua o te Tukanga Hanga

Ka hangaia ēnei tuke mā te whakamahi i ngā tikanga hanga-makariri matatau me te piko tika. Mai i te kowiri tira kounga teitei Ngongo Rinos, ka ata whakapikohia te rauemi mā te whakamahi i ngā mīhini e whakahaerehia ana e te CNC kia rite te matotoru o te pakitara me te āhua porowhita. Mā te tukanga whakakanapa hiko e whai ake nei ka tangohia ngā hapa iti o te mata, ka hangaia he paparanga chromium-oxide tino maeneene, kore e mahi, e whakarei ake ana i te ātete ki te waikura me te whakaiti i te piri o ngā moroiti.

4. Ngā Whakamahinga Noa

• Ngā raina tukatuka miraka me te miraka (whakamātautau, whakakotahitanga, whakakī)
• Te hanga inu (inu ngohengohe, wai hua, pia, waina)
• Ngā pūnaha wai rongoā (wai parakore, wai werohanga – WFI)
• Ngā raina whakawhiti matū rongoā hohe (API)
• Ngā pūwero koiora me ngā kaiwhakaranu i roto i te hanga hangarau koiora
• Ngā pūnaha whakaranu me te kawe kai

5. Ngā Auahatanga me te Tirohanga ki te Mākete

I te mea kei te piki haere tonu te hiahia o te ao mō te tukatuka tino-ma—nā ngā ture haumaru kai tino pakari ake (hei tauira, te FSMA i te US, ngā Ture Akuaku Kai a te EU) me te tere o te tipu o te hanga rongoā koiora—kei te whānui haere tonu te mākete mō ngā tuke maitai kore waikura. Kei te piki haere te tuku a ngā kaihanga i ngā otinga ritenga, pērā i ngā radius motuhake, ngā pūoko whakauru, ngā rauemi ranu rānei, hei whakatutuki i ngā hiahia e whanake haere ana o ngā tono parakore teitei.

6. Whakamutunga

Hei whakarāpopototanga, ko ngā tuke maitai kore waikura te paerewa koura mō ngā pūnaha paipa ma, pono, me te tutuki i ngā whakaritenga i roto i ngā rāngai kai me te rongoā. Ko te whakakotahitanga o te kounga mata tino pai, ngā āhuatanga rauemi pakari, me te mahi kua whakamātauhia i roto i ngā taiao whakaputa o te ao tūturu e pai ai te whiriwhiri mā ngā miihini me ngā kaiwhakahaere e aro nui ana ki te haumaru hua, te whai huatanga o te tukanga, me te tutuki i ngā ture.
