Mu mafakitale opanga chakudya chamafuta ophatikizana, mphero yamafuta ophatikizana ndiye chida chachikulu chomwe chimatsimikizira mtundu wa mapangidwe a mapellet. Kapangidwe komaliza, kuchulukana, ndi kukhazikika kwa chakudya chopangidwa ndi mapellet kumadalira mwachindunji momwe mphero yamafuta opangidwa ndi mapellet imagwirira ntchito. Komabe, panthawi yopanga yeniyeni, gawo lolimba la zinthu nthawi zambiri limakhala pakati pa mphete yamafuta ndi chozungulira, zomwe zimalepheretsa chozungulira kuti chisalowe bwino m'mabowo a mapellet, zomwe zimapangitsa kuti mphete yamafuta opangidwa ndi mapellet igwire kapena chozungulira chigwedezeke - chinthu chomwe chimadziwika kuti "kutseka" kapena "kutsekeka." Nchifukwa chiyani vutoli limachitika, ndipo ndi njira ziti zomwe ziyenera kutengedwa kuti zithetsedwe?
Kusintha Kolakwika kwa Kusiyana Pakati pa Ring Die ndi Roller
Mpata wa die-roller ndiye chinthu chosinthika kwambiri chomwe chimakhudza magwiridwe antchito ndi kukhazikika kwa ma pellet. Mpata ukakhala waukulu kwambiri, makulidwe a zinthu pakati pa die ya mphete ndi roller amawonjezeka, ndipo kufanana kwake kumachepa, zomwe zimapangitsa kuti mphamvu yosagwirizana pa roller ikhale yotsika. Pamene mphamvu yokakamiza yomwe roller imagwiritsa ntchito pa zinthuzo ili yotsika kuposa kukana kwa khoma lamkati la dzenje la die motsutsana ndi zinthuzo, zinthuzo sizingatulutsidwe kudzera m'mabowo a die, zomwe zimapangitsa kuti zitsekeke mwachangu.
Ubwino Woipa wa Nthunzi ndi Mphamvu Yokonza Zinthu
Mikhalidwe Yabwino Yopopera Pellet:
- Kuchuluka kwa chinyezi m'zinthu zopangira:12%–15%
- Kugwiritsa ntchitonthunzi youma yodzaza
- Nthawi yokonza: osacheperaMasekondi 30–45
Nthunzi youma yokwanira imagwira ntchito zosiyanasiyana: kufewetsa zinthuzo, kuchepetsa kutentha kwa kukangana, kukulitsa moyo wa mphete, kulimbikitsa gelatinization ya starch, komanso kulimbitsa ulusi.
Ngati nthunzi ili yotsika, chiopsezo cha kutsekeka chimawonjezeka kwambiri: Kupanikizika kosakwanira kwa nthunzi kapena kuchuluka kwa chinyezi kungapangitse kuti chinyezi cha zinthu zomwe zili ndi mpweya chipitirire 18%, zomwe zimapangitsa kuti chikhale chonyowa kwambiri komanso chofewa, zomwe zimapangitsa kuti friction coefficient mkati mwa mabowo a die ikwere, ndikupangitsa kuti roller slip. Kusinthasintha kwa kuthamanga kwa nthunzi kumabweretsa zotsatira zosakhazikika, zomwe zimayambitsa kusinthasintha kwakukulu kwa mphamvu yayikulu ya injini ya pellet mill, zomwe zingayambitse kutsekeka mwadzidzidzi.
Malangizo a Wogwiritsa Ntchito - Kuwunika Kupanikizika ndi Nthunzi ndi Zinthu
Yang'anirani kuthamanga kwa nthunzi nthawi yeniyeni (0.2–0.4 MPa yovomerezeka). Kufufuza kosavuta: tengani zinthu zochepa zokonzedwa bwino - zikakanikizidwa, ziyenera kupanga mpira; zikatulutsidwa, ziyenera kungosweka. Ziyenera kumva kutentha (70–85°C) yopanda madontho a madzi kapena kumamatira kooneka bwino.
Zipangizo Zokonzera ndi Zofooka za Njira
Kukonza ndi njira yomwe ufa ndi nthunzi zimasakanizidwa bwino, kuyamwa madzi, kuwonjezera kutentha, ndi gelatini mkati mwa chokonza. Kukonza kumatsimikizira mwachindunji kutulutsa kwa pellet mill ndi mtundu wa pellet, ndipo ndikofunikira kwambiri kuti madzi azikhala olimba m'madzi apadera. Ngati kapangidwe ka chokonza ndi kakale, ma paddles atha, kapena nthawi yokonza sikokwanira, zinthuzo zidzaphikidwa mosiyana, ndipo zinthu zina zikadali zosaphika, zomwe zimapangitsa kuti zikhale zosavuta kutseka mabowo ophikira akalowa m'chipinda chopangira pellet.
Pakadali pano, makonzedwe apamwamba amagwiritsa ntchito kuphatikiza kwa"choziziritsa + thanki yosungira + choziziritsira,"kupereka nthawi yonse yokonzekeraMphindi 2–4, zomwe zimathandiza kwambiri kukonza bwino thupi komanso kuchepetsa kutsekeka kwa ziwalo.
Kuwonongeka ndi Kusafanana kwa Ring Die ndi Roller
Kuchepa kwa kusalala kwa mabowo a mphete, kuwonongeka kwa chitoliro chothandizira, kuuma kwa khoma lamkati, kapena kutopa kofanana ndi masitepe zonse zidzawonjezera kwambiri kukana kutulutsa madzi. Pamene ma corrugation a roller atha kufika pamwamba pathyathyathya, mphamvu yogwirira imatayika, ndipo roller imangogwira pamwamba pa zinthuzo. Kuphatikiza apo, kugwiritsa ntchito mphete yatsopano yokhala ndi ma rollers akale, kapena kusagwirizana pakati pa mphete ndi ma rollers, kudzathandizira kutsetsereka ndi kutsekeka.
Zokonzera Zolakwika za Ma Parameter Ogwira Ntchito
- Kuchuluka kwa chakudya mwachangu kwambiri:Kudyetsa zinthu zambiri mkati mwa nthawi yochepa, zomwe zimaposa mphamvu yayikulu yotulutsira zinthu mu mphero, zimapangitsa kuti zinthuzo zisonkhanire mu chipinda chosungiramo zinthu ndipo nthawi yomweyo zimapangitsa kuti zitseke.
- Kusowa kwa kuwunika komwe kukuchitika panopa:Kulephera kukhazikitsa kapena kunyalanyaza alamu ya malire apamwamba a mphamvu yayikulu ya injini, kugwira ntchito kwa nthawi yayitali pamalire apamwamba a mphamvu, kumayambitsa chitetezo chochulukirapo kapena kumayambitsa mwachindunji kugwidwa kwa makina.
Njira Yokhazikika Yosamalira Kutsekeka kwa Mipata
Mukatseka: dinani nthawi yomweyo batani loyimitsa mwadzidzidzi, imitsani chodyetsa ndi chowongolera mpweya nthawi yomweyo, ndikutseka valavu ya nthunzi. Dulani mphamvu yayikulu ndikuyika chikwangwani chochenjeza cholembedwa kuti "Mukukonza - Musatseke Sinthani."
Kukakamiza Kumasula ndi Kutulutsa Zinthu
Ngati chipangizocho chili ndi ntchito yosinthira shaft yayikulu, gwiritsani ntchito jog reverse kuti muchotse zinthuzo.
Mfundo Zofunikira Zogwirira Ntchito:
- Yendani mobwerera m'mbuyo kwaMasekondi 5–10, kenako pitilizani kwa masekondi angapo; bwerezani kangapo.
- Pakati pa kuthamanga kulikonse: osacheperaMasekondi 30kuti injini isatenthe kwambiri.
- Musanabwerere m'mbuyo, onetsetsani kuti palibe zinthu zakunja (monga zidutswa zachitsulo) mkati mwa chipinda chosungiramo zinthu.
- Zindikirani: ntchito yosinthira ndi yakutulutsidwa mwadzidzidzi kokha.
Pazida zopanda ntchito yosinthira kumbuyo kapena pomwe kumbuyo sikugwira ntchito bwino, tsegulani chitseko cha mphero ya pellet, gwiritsani ntchito ndodo yamkuwa kapena ndodo yolimba kuti mugwetse mabowo otsekedwa kuchokera kunja mkati, ndipo gwiritsani ntchito chotsukira chathyathyathya kuti muchotse zinthu zolimba pamwamba pa roller.Musamenyetse mphete mwachindunji ndi nyundo yachitsulo, chifukwa izi zingayambitse kuwonongeka kosatha kwa makina.
Kuyeretsa Bwinobwino ndi Kuyeretsa Mabowo a Die
Chotsani zinthu zonse zotsala kuchokera mkati ndi kunja kwa mphete ya die, ma rollers, scraper, feed cone, ndi zina. Pa mabowo otsekeka kwambiri, gwiritsani ntchito chobowola chamagetsi (liwiro lotsika, kuyika kwamphamvu kwambiri) chokhala ndi chobowola chopanda kanthu chofanana ndi mainchesi a dzenje la die, ndikubowola pang'onopang'ono kuchokera kunja mkati.Musagwiritse ntchito mabowo akuthwa kapena ntchito zokoka, chifukwa izi zitha kukulitsa kapena kuwononga khoma lamkati la dzenje la die.
Mukamaliza kuyeretsa, gwiritsani ntchito tochi yokanikiza kumbuyo kwa dzenje lililonse kuti muwone ngati mabowo onse alowa m'malo amodzi. Ngati ming'alu, kusokonekera kwambiri, kapena kupitirira apo10% ya mabowo opangidwa ndi die ndi opindika kapena osadziwika bwino, mphete iyenera kusinthidwa.
Kuyang'anira Ma Roller ndi Bearing
Yendetsani ma roller pamanja kuti muwone ngati ma bearing amamangirira, phokoso losazolowereka, kapena kusewera kwambiri. Yang'anirani momwe ma roller corrugations amagwirira ntchito. Ngati kutalika kwa dzino kwatha ndipo luso logwira latayika, sinthani roller. Mukasintha ma roller, ndi bwino kuyang'ananso momwe mpheteyo ilili yofanana.
Kuyesa Kopanda Kunyamula ndi Kulowa
Tsekani chitseko, yambani shaft yaikulu popanda zinthu, ndipo thamangani osachitapo kanthu kutiMphindi 1–2kuti mutsimikizire kuti palibe phokoso losazolowereka komanso mphamvu yokhazikika. Kenako onjezerani zinthu zochepa zoyambira zomwe zili ndi pafupifupi2% mafutakapena zinthu zonyowa kuti "zidyetse" ndikuswa die. Onani kuti mphamvu yamagetsi ikukwera pang'onopang'ono ndikukhazikika, kenako pang'onopang'ono muwonjezere kuchuluka kwa chakudya kufika pamlingo wabwinobwino.
M'mphindi 10 zoyambirira mutayambiranso kupanga, limbitsani kuyang'anira;Pambuyo potsimikizira kuti palibe vuto lililonse, bwererani kuntchito yachibadwa.
Mapeto
Kutsekeka kwa mphero ya pellet ndi chizindikiro chokwanira cha kayendetsedwe ka ntchito, kukonza zida, ndi machitidwe ogwirira ntchito. Zomwe zimayambitsa zitha kufotokozedwa m'magawo angapo: kusiyana kwa die-roller, mtundu wa nthunzi, mphamvu ya kukonza, mawonekedwe a zinthu, ndi kasamalidwe ka kukalamba.
Mwa kukhazikitsa kusintha kwa mipata yokhazikika, kukonza bwino mzere wa nthunzi, kukweza njira zowongolera, komanso kuyang'anira kwathunthu ma ring dies ndi ma rollers, kuchuluka kwa kutsekeka kwa magetsi kungachepe ndioposa 80%.
Ngati pali kutsekeka, kutsatira njira yotetezeka, yolongosoka, komanso yothandiza yokonza zadzidzidzi kudzachepetsa kutayika kwa nthawi yopuma. Cholinga chachikulu ndikukwaniritsa ntchito yayitali komanso yokhazikika ya njira yotulutsira ma pellet ndikuchepetsa kwambiri kutsekeka kwa ma pellet.
