Planifter ndiye pachimake, mtima wa gawo logaya mu mphero yamakono. Ngati mphero yodzigudubuza ndi "katswiri wophwanya," ndiye kuti planifter ndi "mbuye wosiyanitsa molondola." Kagwiritsidwe ntchito kake kumatsimikizira mwachindunji kuchuluka kwa m'zigawo, zokolola, mtundu wazinthu, ndi kukhazikika kwa mphero yonse.
I. Ntchito Zazikulu: Kusefa ndi Kukweza
Ntchito yayikulu ya planifter ndikusefa mosalekeza, mogwira mtima, komanso molondola ndikuyesa kusakaniza kochokera ku mphero zodzigudubuza, zomwe zimakhala ndi tinthu tating'ono tosiyanasiyana monga ufa, chinangwa, ndi endosperm.
Kutulutsa Ufa Womaliza:Kulekanitsa zabwino kwambiri particles kuti kukumana specifications ufa kuchokera osakaniza kutumizidwa monga anamaliza mankhwala siteji yotsatira.
Kuyika Ma Stocks Apakati:Kusankha tinthu tating'onoting'ono tomwe sitinakhale bwino m'makalasi osiyanasiyana kutengera kukula ndi mtundu (mwachitsanzo, za chinangwa). Maphunzirowa amaphatikizapo ufa wosalala (dunst), semolina, middlings, ndi chinangwa.
Kukhazikitsa Njira Yoyendera:Kutumiza mwatsatanetsatane katundu aliyense kumakina ake omwe asankhidwa panthawiyo (monga mphero zosiyanasiyana kapena zoyeretsa), potero zimamanga maukonde ozungulira a dongosolo lonse la mphero.
II. Udindo ndi Udindo mu Flour Mill Flow Sheet
Planifter simagwira ntchito payokha. Zimaphatikizidwa ndi mphero kuti apange "grinding-sifting" mayunitsi. Njira yonse yophera imapangidwa polumikiza mayunitsi angapo motsatizana.
Nthawi Yomwe Imachitika:
Chigayo Chodzigudubuza (Kugaya) → Plansifter (Kusefa & Kukuwotcha) → Magawo Osungidwa → Motsatana atumizidwa ku Chigayo chotsatira chomwe chasankhidwa kapena choyeretsa → Reground → Lowetsani Plansifter yotsatira...
Kuzungulira uku kumabwereza, pang'onopang'ono kutulutsa endosperm kuchokera munjere ndikuichepetsa kukhala ufa.
Kapangidwe kadongosolo:Mu mphero ya ufa wa matani 100/tsiku, ma planifters angapo nthawi zambiri amagwiritsidwa ntchito, aliyense amayang'anira ntchito zosefa mkati mwa "machitidwe" osiyanasiyana mwachitsanzo:
Break System Plansifter:Imagwira zinthu kuchokera pamipukutu yopuma. Ntchito zake zazikulu ndikukumba-ufa wapamwamba kwambiri ndi chimanga, tinthu tating'onoting'ono tating'onoting'ono, ndi tinthu tating'onoting'ono tating'onoting'ono.
Kuchepetsa System Plansifter:Imagwira zinthu kuchokera ku mipukutu yochepetsera. Ntchito yake ndikupera bwino ndi kusefa tinthu tating'onoting'ono ta endosperm kuti titulutse{1}}ufa wochepa kwambiri,{2}}wochepa kwambiri.
Scratch System Plansifter:Imagwira zinthu kuchokera pamipukutu yoyambira. Imakonza tinthu tating'onoting'ono ta endosperm yokhala ndi zomata zazing'ono kuti ziyeretsedwe.
Tailings System Plansifter:Imagwira zinthu kuchokera ku ma tailings rolls. Imakonza masheya okhala ndi chimanga chochuluka, cholinga chake ndi kutulutsa ufa wochuluka momwe ingathere ndikusunga kuti ufa ukhale wabwino.
III. Mfundo Yogwirira Ntchito ndi Zomangamanga
Kapangidwe ka Core:
Sieve Casing:Nyumba yamtali yachitsulo, yomwe imagawidwa m'magulu angapo odziimira kapena "magawo."
Mafelemu a Sieve:core ntchito zigawo. Mulu uliwonse wa mafelemu uli ndi masieve okhala ndi mawonekedwe osiyanasiyana (wolukidwa kuchokera ku silika kapena mauna nayiloni). Khomo la ma mesh limakhala lowoneka bwino kuyambira pamwamba mpaka pansi, kapena limakonzedwa molingana ndi zomwe zimafunikira. Zinthuzi zimayenda mozungulira mozungulira mkati mwa mafelemu. Tinthu zing'onozing'ono kusiyana ndi kabowo zimadutsa ("kudutsa"), pamene tinthu tating'onoting'ono timatsalira pamwamba pa sieve ("overtails").
Njira Yoyendetsera:Nthawi zambiri imayendetsedwa ndi mota yoyima yokwera pamwamba. Zimapanga zopingasa, zozungulira ndege kudzera muzitsulo zotsutsana. Kuyenda uku kumafalitsa zinthu zonse pamwamba pa sieve, zomwe zimapangitsa kuti zisunthike mozungulira kunja kuti zigwirizane bwino ndi zobowo.
Njira Yogwirira Ntchito:
Zakudya:Zinthu zapansi zimalowa kuchokera pamwamba pa planifter ndipo zimagawidwa m'zigawo zosiyanasiyana ndi njira zoyendetseratu.
Kusefa Kwachidule:Zomwe zimayendetsedwa ndi kayendedwe ka rotary, zimadutsa motsatizana m'magulu osiyanasiyana a sieve okhala ndi mauna osiyanasiyana.
Kuyika & Kusonkhanitsa:Chigawo chilichonse cha sieve chimagawanitsa zinthuzo kukhala zowonjezera (zosungidwa) ndi zodutsa (zodutsa). Zida zochokera m'magawo osiyanasiyana ndi njira zoyendetsera zimasonkhanitsidwa mosiyana kudzera mumayendedwe amkati.
Kutulutsa:Pomaliza, malo ogulitsira angapo pansi pa planifter nthawi imodzi amatsitsa masitoko osiyanasiyana. Izi zimatumizidwa ndendende (nthawi zambiri ndi pneumatically) kumadera awo.
IV. Zofunika Zaumisiri ndi Zokhudza
Kuchita kwa planifter kumapereka mphamvu ya mphero yonse:
Sifting Surface Area:Malo aakulu osefa amatanthauza mphamvu yapamwamba komanso kusefa mozama. Ubwino waukulu wa planifter ndikukwaniritsa malo akulu osefa mkati mwa phazi laling'ono pomanga zigawo zingapo. Mphero yokwana matani 100/tsiku imafunika malo osefa okwanira okonzedwa molingana ndi kamangidwe kake.
Kukonzekera kwa Sieve:Kusankhidwa kwa masitayilo a sieve (kuwerengera ma mesh, zinthu, kachulukidwe ka nsalu) ndi gawo lofunikira pakupanga mapangidwe. Imatsimikizira mwachindunji kusanja, kuchuluka kwa masheya osiyanasiyana, ndi magawo omaliza a ufa (monga kukula kwa tinthu, phulusa).
Kusefa Mwachangu:Peresenti ya ufa wolekanitsidwa womwe umachokera ku katundu. Kuchita bwino kwambiri kumatsimikizira "kuchotsa kwakukulu," kuchepetsa kubwezeredwa kosafunikira kwa zinthu, kuchulukitsa zokolola za ufa ndi mphamvu, ndikuchepetsa kugwiritsa ntchito mphamvu.
Zoyenda Zoyenda:Liwiro lozungulira ndi eccentricity zimatsimikizira kuthamanga ndi njira yazinthu pamtunda wa sieve. Izi zimafunikira kukhathamiritsa kutengera mawonekedwe a stock ndi masitayilo a sieve.
Kuyeretsa Sieve:Pofuna kupewa khungu (kutsekeka), mafelemu a sieve nthawi zambiri amakhala ndi zida zoyeretsera (mwachitsanzo, zingwe za canvas, mipira ya mphira) zomwe zimagubuduza pansi pa mauna pakugwira ntchito, kuti pobowo asatseke.
V. Mwachidule: "Kulekanitsa Hub" ya Njira Yogaya
Udindo wa planifter ukhoza kumveka mwa mafananidwe:
Malo Owongolera Magalimoto:Pamafunika osakaniza "magalimoto" (nthaka zinthu kuchokera wodzigudubuza mphero) ndi ndendende kutsogolera aliyense galimoto (tinthu) kuti olondola kopita lotsatira zochokera ake "mtundu ndi kopita" (kukula ndi khalidwe).
Quality Gatekeeper:Kupyolera mu magiredi olondola, zimatsimikizira kuti endosperm yokhayokha ndiyomwe imalowa m'dongosolo lochepetsera, zomwe zimathandiza kupanga-ufa wapamwamba kwambiri. Zimalepheretsanso kusweka kwakukulu kwa bran kuti zisawononge ufa, kuonetsetsa kuti ufa ukhale woyera.
Chitsimikizo cha Zokolola ndi Phindu:Kusefa kwa planifter nthawi zambiri kumakhala kolepheretsa kupanga mphero. Kugwira ntchito kwake moyenera komanso kosasunthika ndikofunikira kwambiri kuti mbewuyo ikwaniritse mphamvu zomwe zidapangidwa komanso kuchuluka kwake.
Popanda planifter, kupanga mphero yaufa moyenera, yolondola, ndi mosalekeza sikutheka. Imayima mwakachetechete mu mphero, ikuchita "malamulo osankhira" ovuta komanso olondola kudzera m'mabowo ake amkati mwa masauzande ambiri, omwe akuyimira chimodzi mwazinthu zofunikira kwambiri paukadaulo wapaulendo kuyambira "kugaya" mpaka "ufa womalizidwa."
