Te Tāke Whakarewa i roto i te Hanga Mākarini

He aha i hiahiatia ai te Emulsification?

He ranunga hinu-i-te-wai (O/W) te mākārini, engari mā te tukatuka, ka hurihia hei ranunga wai-i-te-hinu (W/O) pumau. He mea nui te waihanga tuatahi o tētahi ranunga-mua ōrite mō:

1. Te Mararatanga Taurite:Kia tika te tohatoha o ngā pata wai (kei roto te tote, ngā pūmua miraka, ngā mea tiaki pērā i te waikawa sorbic, me ngā mea waikawa pērā i te waikawa lactic) puta noa i te wahanga ngako.
2. Whakaurunga o ngā Kai:Te whakarewa me te whakamarara tika i ngā kai iti katoa pēnei i ngā emulsifier, ngā tae, me ngā kakara.
3. Te Pūmautanga o te Tukanga:Te whakarato i tētahi whāngai ōrite, ōrite hoki ki te wae whakamatao o raro. Mā te kore ōrite o te whakauru i mua i te emulsion ka hua he hua kino te kakano, he marara wai kore pumau, ā, ka raru pea te pirau.

Ngā Wāhanga Matua o te Tāke Whakarewa

Ko te tāke noa he oko poutū kua kati, kua hipokina ki te koti, he mea hanga ki te maitai kore waikura (hei tauira, 304, 316L rānei) hei ārai i te waikura me te pirau. Ko ōna wāhanga matua ko:

1. Pūnaha Whakaohooho:Koinei te wāhanga tino nui. Ko te tikanga he:
   • He Whakaranu Kutikuti Tere-Tiketike (Impeller):He maha ngā wā ka whakamahia he impeller rere-ā-rohe pērā i teRanu Turbo-Rotor-StatorKa hangaia he kutikuti miihini kaha, ka kukume i te wai mai i runga, ka panaia mā roto i ngā pūaha angiangi o te stator, ka pakaru pai ngā pata me te hanga i te emulsion.
   • He Pūwero Punga, he Pūwero Hoe rānei:He mīhini waru tere puhoi e neke tata ana ki te pakitara o te tāke. Ko tāna mahi he whakarite kia neke ngā rauemi katoa i roto i te tāke, kia kore ai e mate ngā wāhi, kia ōrite hoki te puranga katoa. Ka ārai i te ngako kia kore ai e piri ki ngā pakitara matao o te tāke kua hipokina.
2. Koti Whakamahana/Whakamatao:He uhi takirua kei te pakitara o te tāke e rere ai te wai wera (te nuinga o te wai wera). He mea nui tēnei mō:
   • Te rewa:Me whakarite kia wai katoa ngā ngako me ngā hinu i mua i te whakaemulsification.
   • Whakahaere Pāmahana:Te pupuri i te ranunga i te pāmahanai runga ake i te pūwāhi rewa o te wāhanga ngako rewa teitei rawa(ko te tikanga he 5-10°C ki runga ake, he maha ngā wā kei te 45-60°C). He mea nui tēnei hei ārai i te whakatiotanga wawe, ka whakangaro i te whakamomona.
3. Ngā Tauranga Kai:He maha ngā rārangi tomokanga hei tāpiri i ngā wāhanga rerekē:
   • Ngā rārangi matua mō te ranunga hinu wera nui me te wāhanga wai/tote.
   • He tauranga iti ake mō ngā kai iti pēnei i te lecithin, ngā kakara, ngā tae, me ngā huaora.
4. Pūnaha Korehau (Whiringa engari he mea noa):Ka taea te whakahaere i te tāke i raro i te mīhini whakakore hau ngawari. E rua ngā mahi a tēnei:Pūnaha Whakahaere:Kua whakauruhia ngā tāke hou ki tētahi pūnaha PLC/SCADA hei whakahaere aunoa i te pāmahana, te tere whakaoho, te raupapa tāpiri kai, me te wā pupuri.
   • Te whakakorenga hau:Ka tangohia te hau e mau ana i roto i te ranunga, ka ārai i te kakano pūngāwerewere, kirikiri rānei i roto i te pata whakamutunga, ā, ka whakapai ake i tōna matotoru me tōna āhua.
   • Taiao Whakahaeretia:Ka ārai i te waikura o ngā hinu tairongo i te wā e tukatukahia ana.

Te Raupapa Whakahaere

Ko te tukanga i roto i te tāke emulsification e whai ana i tētahi raupapa motuhake:

1. Te utu:Ko te ranunga hinu wai (kei roto ngā ngako mārō, ngā hinu ngohengohe, me ngā emulsifier wairewa-ngako pērā i te mono- me te diglycerides) ka papua tuatahitia ki roto i te tāke. Ka whakakāhia te whakamahana koti hei pupuri i te pāmahana.
2. Whakaranu:Ka tīmata te whakaoho punga hei hanga i tētahi awhiowhio.
3. Tāpiritanga:Ka āta inehia te wāhanga wai (kei roto ko te wai, te tote, ngā mea tiaki, me ngā kai wairewa-wai) ki roto i te awhiowhio o te wāhanga hinu e hurihuri ana.Te tāpiri wai ki te hinu (kaua te ritenga kē)ka whakatairanga i te hanganga o te wai-i-roto-hinu emulsion.
4. Te Whakapūtanga Kutikuti-Tiketike:Kia oti ngā wāhanga e rua te whakauru, ka whakahohehia te mīhini whakaranu rotor-stator kutikuti-teitei mō tētahi wā kua whakaritea (hei tauira, 5-15 meneti) hei hanga i te pre-emulsion pai.
5. Te pupuri:Ka puritia te ranunga i raro i te whakaoho mārie me te whakahaere i te pāmahana kia rite rā anō mō ​​te papu ki te wāhanga e whai ake nei (te mīhini whakamātao, mēnā e tika ana, kātahi ko te wāhanga whakamatao).

He aha te mea ka tupu i muri mai?

Kātahi ka papua te emulsion matotoru mai i tēnei tāke ki tētahiwhakawhiti wera mata waru (Votator™, A-unit rānei)I konei, i raro i te whakamatao nui me te mahi miihini, ka whakatio te ngakohuri noangā pata wai kua marara pai, e whakau ana i te wai-i-roto-i-te-hinu, e hanga ana hoki i te hanganga kirihou whakamutunga me te kakano o te pata.

Whakarāpopototanga: Ngā Kaupapa Matua

• Kaupapa:Hei waihanga i tētahi whakarewa-mua ōrite, matotoru, me te pumau o ngā āhua ngako me te wai.
• Tawhā Matua: Whakahaere pāmahanahe mea nui kia noho rewa tonu ngā ngako katoa.
• Tikanga Matua: Te whakaohooho miihini kutikuti-teiteie whakamahia ana hei wawahi i te āhua wai kia miriona ngā pata ririki.
• Hua:He whakaemulsion-mua ōrite e whakarite ana kia ōrite te kakano, te reka, te tae, me te pumau o te hua pata whakamutunga.

Ko te tikanga, ko te tāke whakapūhui te kaupapa mō ngā mea katoa e whai ake nei. Kāore e taea te whakatika i tētahi whakapūhui ngoikore i konei ā muri ake nei, ā, ka hua ake he hua whakamutunga kāore i te kounga teitei.
