Plansifter ndiye pakatikati, mtima, gawo la mphero mu mphero yamakono. Kugwira ntchito kwake kumatsimikizira kuchuluka kwa mpheroyo, kuchuluka kwa kupanga, mtundu wazinthu, komanso kukhazikika kwa kupanga.
Ngati mphero yodzigudubuza ndi "katswiri wophwanya," ndiye kuti Plansifter ndiye "mbuye wosankha bwino." Tsatanetsatane wotsatirawa ntchito yake mu mphero.
I. Cholinga Chachikulu: Kusefa ndi Kugawa
Cholinga chachikulu cha Plansifter ndikusefa mosalekeza, mogwira mtima, komanso moyenera ndikuyika "nthaka" kuchokera ku mphero zodzigudubuza (ie, positi-kusakaniza kogaya komwe kumakhala ndi tinthu tating'ono tosiyanasiyana, chinangwa, tinthu tating'onoting'ono ta endosperm, ndi zina zotero).
Kutulutsa Ufa Womaliza:Amalekanitsa ufa wabwino kwambiri-ogwirizana ndi ufa (omwe nthawi zambiri umatchedwa "mesh" kapena "μm") kuchokera mumsanganizo, kuwalondolera ngati ufa womalizidwa kunjira ina (monga sefa, kulongedza, kapena kusakaniza ufa).
Gulu lazinthu:Imayika tinthu tating'onoting'ono tomwe sitinakhale bwino kuti titha kukhala ufa m'makalasi osiyanasiyana kutengera kukula ndi mtundu (mwachitsanzo, za chinangwa), monga:
Semolina / Coarse Middlings:Zazikulu, zoyera endosperm particles.
Nthambi Yabwino / Nthambi Yolimba:Nthambi particles kunyamula pang'ono endosperm.
Coarse Bran:Zipatso zazikulu.
Kugawa Zinthu:Imayendetsa ndendende mtsinje uliwonse kupita ku makina ake okonzekera, potero kupanga mphero yonse.
II. Udindo ndi Udindo mu Mayendedwe a Chigayo
Plansifter simagwira ntchito payokha. Zimaphatikizidwa ndi mphero kuti apange "grinding-sifting" loop units. Njira yonse yophera ndi mndandanda wamagulu olumikizana otere.
Njira Yokhazikika:
Chigayo cha Roller (Kugaya) → Plansifter (Kusefa/Kusankha) → Mitsinje Yosankhidwa → Yotumizidwa kumagulu otsatirawa-Magila Odzigudubuza kapena Oyeretsa → Kubwezeretsanso → Kubwerera ku Plansifter...
Kuzunguliraku kumabwerezabwereza, kumagwira ntchito ngati chingwe cholumikizira molondola, ndikumavula pang'onopang'ono ndikuyeretsa endosperm ya tirigu kuchokera munjere.
Kapangidwe kadongosolo:Mu mphero ya ufa wa matani 100/tsiku, ma Plansifters angapo amatha kusefa "machitidwe" osiyanasiyana mwachitsanzo:
Break System Plansifters:Njira yopangira zinthu kuyambira pakupuma koyambirira. Ntchito yawo yaikulu ndi kutulutsa ufa wochuluka wochuluka ndi kulekanitsa chinangwa ndi ana aang'ono okhuthala ndi abwino.
Kuchepetsa System Plansifters:Sungani zinthu kuchokera ku mipukutu yochepetsera. Ntchito yawo ndikupera bwino ndi kusefa ma endosperm kuti atenge{1}ufa wapamwamba kwambiri.
Sizing System Plansifters:Sungani zinthu kuchokera pamizere yozungulira. Ntchito yawo ndikuchiza tinthu tating'onoting'ono ta endosperm yokhala ndi chinangwa chocheperako, kuti muyeretsedwenso ndikuchotsa ufa.
III. Mfundo Yogwirira Ntchito ndi Zomangamanga
Plansifter (dzina lonse: High Square Horizontal Plansifter) imatengera dzina lake kuchokera ku kabati yake yayitali, ya masikweya-monga kamangidwe kake, kokhala ndi zigawo zingapo za mafelemu oyikidwa mopingasa.
Kapangidwe ka Core:
Mlandu wa Sieve:A wamtali zitsulo dongosolo mkati anagawa "zipinda."
Mafelemu a Sieve:core ntchito zigawo. Fungo lililonse limakhala ndi zisefo (silika kapena nayiloni) za makulidwe ake enieni, okhala ndi kabowo kakang'ono kamene kamakhala kowoneka bwino kuchokera pamwamba mpaka pansi. Zinthu zimayenda mkati mwa mafelemu; tinthu ting'onoting'ono kusiyana ndi kabowo "amadutsa," pamene zazikulu "zimasungidwa."
Njira Yoyendetsera:Nthawi zambiri imayendetsedwa ndi injini yoyimirira pamwamba, imapanga kuzungulira kwa ndege (kofanana ndi mabwalo ojambulira) kudzera pa masikelo oyambira. Kuyenda uku kumagawanitsa zinthu pamwamba pa sieve kuti zigwirizane bwino ndi zobowola ndikupewa kugunda molunjika (komwe kungasokoneze gulu lomwe lakwaniritsidwa).
Njira Yogwirira Ntchito:
Kudyetsa:Zogulitsa pansi zimalowa kuchokera pamwamba, zimagawidwa m'zipinda zosiyanasiyana ndi njira zosefa.
Kangapo-kusefa masanjidwe:Zinthu zimadutsa muzosakaniza za sieve motsatizana pansi pa kayendetsedwe ka rotary.
Gulu & Kutolera:Sieve iliyonse imagawaniza zinthuzo kukhala "zowonjezera" (zosungidwa) ndi "kupyolera" (kudutsa). Zowonjezera ndi zodutsa kuchokera kumagulu osiyanasiyana ndi njira zimasonkhanitsidwa kudzera mumayendedwe amkati.
Kutulutsa:Pomaliza, mitsinje ingapo ya zinthu zamagulu (mwachitsanzo, mtundu umodzi wa ufa, mitundu iwiri ya semolina, mtundu umodzi wanthambi) imatuluka nthawi imodzi kuchokera m'malo osiyanasiyana omwe ali pansi ndipo amanyamulidwa ndendende kudzera pa mapaipi a mpweya kupita komwe akupita.
IV. Zofunika Zaumisiri ndi Zokhudza
Kachitidwe ka planifter kumapereka mphamvu ya mphero yonse:
Malo Osefera:Malo okulirapo amawonjezera mphamvu ndikuwonetsetsa kusefa bwino. Kuchuluka-kusanjikizana kwa Plansifter kumapereka malo akulu osefa mkati mwa phazi locheperako, mwayi wake waukulu.
Kukonzekera kwa Sieve:Kusankhidwa ndi kukonza ma meshes a sieve (kuwerengera ma mesh, zinthu) ndiye mzimu wamapangidwe. Imatsimikizira kulondola kwamagulu, kuchuluka kwa mitsinje yosiyanasiyana, komanso mtundu wa ufa.
Kusefa Mwachangu:Maperesenti a sieve-ufa wofunkhidwa. Kuchita bwino kwambiri kumatanthauza kutulutsa kwakukulu, kuchepetsa kubwezeredwa kwa zinthu zosafunika, potero kumakulitsa kuchuluka kwa m'zigawo ndi kutulutsa.
Liwiro & Kusatsimikizika:Dziwani momwe zinthu zimayendera komanso momwe zimayendera pa sieve, zomwe zimakhudza zotsatira za kusefa ndi kutuluka. Izi zimafuna kusintha kutengera mawonekedwe azinthu zosiyanasiyana.
V. Mwachidule: "Chigawo Chosankha" cha Njira Yogaya
Udindo wa Plansifter ukhoza kumveka mophiphiritsa:
Transport Hub:Imawongolera positi-kukupera "mixed traffic" (ground stock) pa "misewu" yosiyana kutengera "mtundu wagalimoto ndi komwe ikupita" (kukula kwa tinthu ndi mtundu wake), kuwonetsetsa kuti mtsinje uliwonse ukuyenda bwino poyimitsa kwina.
Quality Control Point:Kupyolera m'magulu olondola, amaonetsetsa kuti ma endosperm okhawo alowa m'dongosolo lochepetsera, zomwe zimathandiza kupanga-grade, low-ufa wa phulusa. Zimalepheretsanso kupitirira-kugaya chimanga, kuteteza ufa wosayera.
Chinsinsi cha Zotulutsa & Phindu:Kutha kusefa kwa Plansifter ndi chimodzi mwazomwe zimalepheretsa kukula kwa mphero. Kuchita kwake koyenera, kokhazikika ndikofunikira kuti munthu akwaniritse luso lopangidwa komanso kuchuluka kwake.
Popanda Plansifter, kupanga mphero yaufa yogwira mtima, yolondola, ndi mosalekeza sikukanakhala kosatheka. Itaimirira mwakachetechete m'mpheroyo, imapanga "malangizo osankha" ovuta komanso olondola kudzera m'mabowo ake ambirimbiri amkati. Ndi imodzi mwamalumikizidwe ozama kwambiri aukadaulo paulendo wa mphero kuchokera ku "kupera" kupita ku "mankhwala omalizidwa."
