I roto i te hanga whāngai hou, ko te raina whakaputa pire te kaupapa matua o te tukanga tukatuka katoa. Ina puta he hapa taputapu, ka whakararuraru i te wāhanga whakaputa pire, engari ka heke whakamuri ki te huri me te whakaranu, ka anga whakamua ki te whakamatao me te takai. Ko te utu o te wā whakamutu kore i whakamaheretia i roto i te mira whāngai waenga-ki-rahi ka neke atu i te mano tāra ia haora ina whakaarohia te ngaronga o te whakaputanga, te mangere mahi, me te whakaroa tuku. Ka tirohia e tēnei tuhinga ngā hapa e tino kitea ana i roto i ngā raina whakaputa pire, ka tātarihia ō rātou take pūtake, ā, ka whakaatu i ngā otinga pūnaha i runga i ngā mātāpono miihini me te wheako mara. Ko te whāinga ehara i te whakatairanga i tētahi waitohu kotahi engari ko te whakarato i ngā kaihanga whāngai me ngā anga tātaritanga mahi ka taea te mahi hei whakaiti i te wā toharite ki te whakatika me te whakapai ake i te whai huatanga o ngā taputapu whānui.
Te Ārai Mate me te Tohatoha Rauemi Kore Taurite
Te Tāutu i ngā Tohu
E toru ngā tohu e kitea ana e ngā kaiwhakahaere te aukati o te mate: he pikinga ohorere o te iahiko matua o te motuka, he hekenga ohorere o te putanga pire i te awa tukunga, me te panonitanga o te tangi o te mira pire — e kiia ana he haruru "hurihuri āputaputa". I ngā wā tino kino, ka whati te pine kutikuti haumaru, ka puta he whakaweto aunoa.
Tātaritanga Take Pūtake
Kāore i te maha ngā wā ka puta te aukati o te mate i te mea kotahi. E whakaatu ana ngā rangahau mara puta noa i ngā wāhi whakaputa maha i tētahi tauira noa: te taunekeneke i waenga i te kounga o te whakatikatika rauemi me te kore taurite o ngā whakaritenga o te mate. Ina kore e tutuki i te whakatikatika mamaoa te taumata makuku e hiahiatia ana o te 15–17% me te pāmahana o te 80–85°C, ka uru te whāngai paraoa ki te mate me te kore e ranea te kirihou. Kātahi ka whakakīkī te rauemi i roto i ngā kōhao mate, ka hangaia he rohe pēhi-rahi e whakawhāiti haere ana i te rohe mate whai hua.
Ko tētahi atu take ko te kohikohinga o ngā konganuku me ngā maramara whakarewa i roto i ngā kōhao o te mate. Ahakoa kua tāutahia ngā wehewehenga aukume ki runga ake, ka taea e ngā matūriki rino iti iho i te mirimita te whakauru ki roto i ngā pakitara o te kōhao o te mate, ka piki ake te tauwehenga waku mā te 15–30% i roto i ētahi huringa whakaputa.
Otinga Pūnaha
E whai ana te huarahi whakatikatika i tētahi kawa e toru ngā wāhanga:
Kati te whakauru whāngai, huri ki te ranunga purapura hinu (ko te nuinga he 5–8% te ihirangi hinu) ka whakahaere i te mira i te tere whakaiti mō te 3–5 meneti. Ka mahi te hinu hei hinu whakahinuhinu, ka horoi mārire i ngā rauemi kua kikī mai i ngā kōhao mate. Ka ora ake tēnei tikanga i te tata ki te70% o ngā mate kua āraiame te kore e hiahiatia te tango i te mate.
Ki te kore e angitu te Wāhanga 1, tangohia te huihuinga o te mate, ka tirotirohia ia rarangi poka i raro i te rama e tika ana. Whakamahia he pū horoi hau me ngā ngira maitai whakapakeke e rite ana ki te diameter o te poka mate taketake. Kaua rawa e whakamahi i ngā taputapu horoi nui rawa, nā te mea ka whakanuia e rātou ngā poka mate, ā, ka whakarerekē tonu i ngā ōwehenga kōpeketanga.
Arotakehia ngā haora 48 whakamutunga o ngā rārangi whakaputa. Whakatikatikahia te pēhanga mamaoa kia mau tonu te pēhanga2.0–2.5 paei te tomokanga whakangawari. Manatokohia ka taea e te pihi piki-ake o te tere whāngai te eke ki te taurite wera i mua i te tīmatanga o te whāngai kawenga-katoa — he wā whakamahana 3–5 meneti i te tere whāngai 50% ka whakaiti nui i ngā aituā aukati tīmatanga-makariri.
Kounga Pellet Kāore i te ōrite, me te Taupū Pakeke Iti
Te Tāutu i ngā Tohu
Ko te rerekētanga o te kounga ka puta mai i ngā pire he rerekē te roa (kua hipa te manawanui ±10% i te whāinga), he nui rawa ngā mea iti i roto i te putanga o te pouaka whakamatao (neke atu i te 3% te taumaha), me te hekenga o te Taurangi Pakari o te Pellet i raro i te paearu ahumahi o95% mō te whāngai heihei or 97% mō te whāngai wai.
Tātaritanga Take Pūtake
Ko te taupū pakari o te pereti e whakahaeretia ana e ngā taurangi e toru e pā ana ki a rātou anō: te ōwehenga kōpeketanga o te mate, te tohatoha rahi o te matūriki o te rauemi whenua, me te mahi here i raro i ngā āhuatanga whakatikatika motuhake. Ko tētahi tātaritanga hē noa ko te kī he ngoikore te pakari o te mate nā te kakahu o te mate anake. Ahakoa he take te kakahu o te mate - ko te mate e mahi ana i tua atu i te 50,000–60,000 tana o te putanga ka whakaatu i te whakanui i te kōhao ka taea te ine - ko te take e tino kitea ana ko te rahi matūriki kāore i te ōrite mai i te wāhanga huri. Ina whakaputa te mira hama i te tohatoha rahi matūriki whānui me te paerewa rerekētanga āhuahanga neke atu i te 2.0, ka whakakīia e ngā kiko ngā āputa i waenga i ngā matūriki nui ake i roto i ngā kōhao mate, ka hangaia he papa kutikuti ngoikore i roto i te pereti kua oti.
Otinga Pūnaha
Me tīmata te raupapa tātaritanga i te tihi:
Kohia ngā tauira i te mīhini whakaranu i ia rua hāora mō te huringa katoa. Whakamahia he mīhini ruirui tātari Ro-Tap me ngā tātari i te 300, 500, 1000, me te 2000 maikorona. Ko te whāinga D50 mō te whāngai heihei parai paerewa ko600–700 maikoroname te paerewa rerekētanga āhuahanga i raro i te 1.8. Mena ka nui ake te rerekētanga i tēnei paepae, tirohia te āhua o te mata o te mira hama me te āputa o te pito hama.
Inehia te rerekētanga pāmahana i waenga i te tomokanga me te putanga o te whakamahana. Ko te hekenga neke atu i te 5°C i waenga i te tomokanga mamaoa me te mash whakamahana he tohu i te ngaronga wera i roto i te oko whakamahana — ko te nuinga o te wā nā te kore e ranea te whakamarumaru, te kohikohinga wai mātao rānei i roto i te raina mamaoa. Tāutahia he mahanga mamaoa i roto i te 3 mita o te tomokanga whakamahana, ā, manatokohia tōna mahi ia wiki.
Whakaūtia kei te ōrite te ōwehenga kōpeketanga o te mate (te roa o te kōhao whai hua i wehea ki te whānui o te kōhao) ki te whakatakotoranga. Mō te whāngai heihei parai paerewa me te 12–14% te makuku i muri i te whakamakuku, he ōwehenga kōpeketanga o1:8 ki te 1:10he tika. Mō ngā kai ruminant he nui te muka, ko ngā ōwehenga o1:10 ki te 1:12whakarato i te roa o te ora.
Te Hekenga o te Pūmanawa me te kore he Tohu Hapa Mārama
Te Tāutu i ngā Tohu
Koinei te raruraru whakaputa tino kino: kei te mahi tonu te mira pirepire me te kore he whakaoho, he hapa rānei e kitea ana, engari ka heke haere te kaha whakaputanga noa mā te10–20%mō ētahi wiki. He maha ngā wā ka whakaaetia tēnei e ngā kaiwhakahaere whakaputa hei "kakahu noa" ā, ka whakatikatika mā te whakaroa i ngā hāora mahi, ka huna i te raruraru matua, ka whakapiki ake hoki i ngā utu pūngao.
Tātaritanga Take Pūtake
Ko te hekenga āta haere o te kaha whakawhiti raraunga e ahu mai ana i ngā pūtake e toru:
I te pakaru o ngā anga roera, ka rerekē te koki o te titi i waenganui i te roera me te mate. Me nui ake te hurihanga o te roera kua pakaru me te diameter o waho kua iti ake hei pēhi i te rahinga rauemi ōrite. E taunakihia ana kia whakakapia ina heke te diameter o waho neke atu i te3mmmai i te whakatakotoranga taketake.
Ka kohia e te pūnaha whakamatao me te pūnaha mimiti te puehu ki runga i ngā mata o te pā, ngā mata whakawhiti wera, me ngā pakitara o te hauāwhiowhio. Ka taea e te paparanga puehu 5mm i runga i te impeller pā centrifugal te whakaiti i te rere o te hau mā te8–12%, e pā tika ana ki te pai o te whakamahinga o te mīhini whakamatao.
Ko te nui haere o te tauine kōhua he 1mm noa te matotoru ka whakaiti i te pai o te whakawhiti wera mā te tata ki10%Ko te tikanga o tēnei, he nui ake te wai whakapūhau me te iti iho o te wera huna e kawea ana e te mamaoa e tae atu ana ki te whakamahana, ā, ka āta whakaitihia te pāmahana whakamahana ahakoa kāore anō kia rerekē te tūranga o te takirere mamaoa.
Otinga Pūnaha
Whakatinanahia he kaupapa tiaki ārai kua whakaritea me ngā pūwāhi whakaoho kua inehia:
Tuhia te diameter o waho o te roera i ia whakawhiti mate. Tuhia te tere o te kakahu (mm mō ia 1,000 tana) ka whakaritea he whakakapinga ina tae te rārangi ia ki te rohe kakahu 3mm i roto i te matapihi tiaki kua whakaritea e whai ake nei - kaua i muri i te hipa kē.
Whakatūria he tikanga horoi ā-hauwhā mō ngā wāhanga whakahaere hau katoa. Whai muri i te horoinga, inehia, ka tuhia te rerekētanga pēhanga pumau puta noa i te moenga whakamatao i te kawenga katoa.15% te pikingamai i te pānui āhua ma o te turanga ka tīmata te tirotiro i waho o te huringa.
Tāutahia he pūoko kounga mamaoa (e ine ana i te haurua maroke) ki te tomokanga o te whakamahana. Ina heke te haurua maroke ki raro iho i te0.92, tīmatahia te pupuhi o te poiha, ka tirotirohia ngā mahanga mamaoa i runga i te raina tuku. Tuhia te whanaungatanga i waenga i te pēhanga whakahaere o te poiha me te kounga o te mamaoa i te wā e whakamahia ana — mā tēnei raraunga ka taea te tiaki matapae, kaua ki te tiaki tauhohe.
Ngā Haerenga o te Pāmahana o te Pei me ngā Rahunga Whakahinuhinu
Te Tāutu i ngā Tohu
Ka mahi ngā peera matua o te mira pellet i roto i tētahi taiao e whakakotahi ana i ngā kawenga radial teitei (te tikanga200–400 kNmō te mīhini 30–40 tana ia hāora), ngā pāmahana taiao teitei (40–60°C tata ki te mate), me te noho tonu ki te puehu angiangi. Kei runga ake te pāmahana o te peera75°Che tere pikinga rānei e neke atu ana i te2°C ia menetie tika ana kia tirotirohia tonutia.
Tātaritanga Take Pūtake
He tauira matapae te āhua o ngā pakaru o ngā peera i roto i ngā mira pellet. Ehara te momo pakaru matua i te pakaru o te ngenge — e tika ana kia rite ki ngā āhuatanga o te kawenga — engari ko te poke o te hinu whakahinuhinu me te matekai i muri mai. He iti ngā matūriki puehu whāngai i roto i te awhe 5–20 micron hei uru ki ngā hiri labyrinth engari he nui hei whakakoi i ngā ara rere o te peera. Kia poke te hinu whakahinuhinu, ka piki te pāmahana whakahaere o te peera, ka tere ake te waikura hinu, ka whakaiti ake i te whai huatanga o te whakahinuhinu — he huringa pakaru whakakaha-ake.
Otinga Pūnaha
Ka whakakotahi te otinga i ngā mana whakahaere hangarau me te tikanga whakahaere:
Whakahouhia ngā peera matua me ngā pūnaha whakahinuhinu aunoa momo-whakamua e tuku ana i ngā rahinga hinu kua inehia i ngā wā ka taea te whakarite. Me tuku e te pūnaha te tata ki0.5–1.0 cm³ o te hinu mō ia peera i ia hāorai te wā e mahi tonu ana, me te tere tika i whakaritea ki te rahi o te peera me te pāmahana whakahaere.
Tāutahia ngā pūoko pāmahana whāriki me te āheinga tuhi raraunga. Whakatakotoria ngā paepae whakaoho ki70°C (whakatūpato)me80°C (whakamutu whāngai aunoa)Tātarihia ngā raraunga ia wiki mō te ia o te pāmahana — he tohu pono ake te pikinga mārire o te 0.5°C i ia wiki i roto i ngā wiki e ono mō te hinganga e haere ake nei i tētahi pānui pāmahana kotahi.
Whakamahia he hinu matatini-litium me te iti rawa o te pūwāhi maturuturu o260°Cme te matotoru o te hinu turanga o220–460 cSt i te 40°CMe paahi hoki te hinu i te whakamātautau waikura parahi ASTM D4048 i te pāmahana whakahaere mōrahi e tumanakohia ana.
Whakamutunga
Ko te rapurongoā whai hua mō te raina whakaputa pellet me neke atu i ngā huarahi "whakatika ina pakaru" tauhohe ki ngā anga tātaritanga pūnaha. Ko ngā wāhanga hapa e whā e kōrerohia ana — te aukati mate, te koretake o te kounga, te hekenga o te kaha whakaputa, me ngā rahunga peera — e whakaatu ana i te tata ki80% o te wā whakatā kore i whakamaheretiai roto i ngā mahi hanga whāngai noa.
Ko te kaupapa matua o ngā otinga katoa ko te whakaurunga o te ine, te tuhi tuhinga, me te tātari ia au ki roto i ngā mahi o ia rā. Ina whai wāhi ngā kaiwhakahaere me ngā tīma tiaki ki ngā raraunga tūāpapa kua inehia me ngā pūwāhi mārama hei wawaotanga, ka tino heke te wā whakatika, ā, he mea nui ake, ka taea te ārai i ngā hapa maha mā te tiaki e hangai ana ki ngā āhuatanga.
Mō ngā kaihanga whāngai e hiahia ana ki te whakapai ake i te pono o te raina whakaputa, ehara i te mea ko ngā taputapu hou te tīmatanga engari he huarahi whai tikanga ki te mārama me te whakahaere i ngā taputapu kua whakamahia kētia. Ka pā ngā mātāpono kua whakarārangihia i roto i tēnei tuhinga puta noa i ngā waitohu me ngā whirihoranga o te mira pire, ā, kāore e hiahiatia he whakapaunga whakapaipai i tua atu i ngā taputapu taketake me te whakangungu.
