Iyo Plansifter ndiyo musimboti, moyo, wechikamu chekugayo muchigayo chemazuva ano cheupfu. Hunyanzvi hwekushanda hwayo hunotarisisa mwero wekutorwa kwechigayo, huwandu hwekugadzira, mhando yechigadzirwa, uye kugadzikana kwekugadzira.
Kana chigayo chiri "nyanzvi inopwanya," saka Plansifter ndiyo "chaiyo yekuronga tenzi." Mashoko anotevera mashandisirwo ayo muchigayo cheupfu.
I. Chinangwa Chakakosha: Kupepeta uye Kuisa Mutsa
Chinangwa chikuru chePlansifter nderekuenderera mberi, nemazvo, uye kunyatsosefa nekuisa "ground stock" kubva kumaroller (kureva, posvo-musanganiswa wekukuya une zvidimbu zveupfu zvakasiyana-siyana, bran, endosperm particles, nezvimwewo).
Kusvina Finished Flour:Inopatsanura zvakanakisa, zvakatemerwa-zvimedu zveupfu zvinowirirana (zvinowanzonzi "mambure" kana "μm") kubva mumusanganiswa, zvichizvitungamira sehupfu hwapera kune imwe nzira inotevera (semuenzaniso, sefa, kurongedza, kana kusanganisa hupfu).
Material Classification:Inoisa zvidimbu zvakakura zvisati zvakwana kuti zvive hupfu mumagiredhi akasiyana zvichienderana nehukuru uye mhando (semuenzaniso, bran content), senge:
Semolina/Coarse Middlings:Yakakura, yakachena endosperm particles.
Fine Bran/Coarse Bran:Bran particles inotakura zvishoma endosperm.
Coarse Bran:Huru bran flakes.
Kugoverwa kwezvinhu:Iyo inonyatso fambisa nzira yega yega yakasarudzika kumuchina wayo unotevera wekugadzirisa, nekudaro ichivaka iyo yese milling kuyerera.
II. Nzvimbo uye Basa muMill Process Flow
Iyo Plansifter haishande iri yega. Inobatanidzwa nema roller mill kuita "grinding-sefa" loop units. Kugayo kwese kutevedzana kwezvikamu zvakabatana zvakadaro.
Typical Process Loop:
Roller Mill (Kukuya) → Plansifter (Kupepeta/Kuisa Mutsara) → Mitsara Yemhando → Yakatumirwa kune anotevera-danho reMaumburu Emagayo kana Anonatsa → Regrinding → Kudzokera kuPlansifter...
Kutenderera uku kunodzokororwa, kushanda semutsetse chaiwo wekusangana, zvishoma nezvishoma uchikurura nekunatsa endosperm yegorosi kubva mubran.
System Layout:Mune 100-ton/day yehupfu chigayo, akawanda maPlansifters anowanzo kubata kusefa kune akasiyana "masystem," semuenzaniso:
Break System Plansifters:Gadzirisa zvinhu kubva kune ekutanga break rolls. Basa ravo guru nderokuchera huwandu hukuru hwehupfu hwemhando uye kupatsanura bran kubva kune yakakasha uye yakanaka middlings.
Kuderedza System Plansifters:Gadzirisa zvinhu kubva kumapumburu ekudzikisa. Basa ravo nderekukuya nekusefa endosperm yakachena kuti ibvise-hupfu hwegiredhi repamusoro.
Saizi System Plansifters:Gadzirisa zvinhu kubva kune saizi rolls. Basa ravo ndere kubata endosperm particles ine shoma bran yakasungirirwa, kuti iwedzere kucheneswa uye kubviswa kwehupfu.
III. Kushanda Nheyo uye Zvimiro Zvimiro
The Plansifter (zita rizere: High Square Horizontal Plansifter) inowana zita rayo kubva kurefu, square cabinet-sechimiro, yakarongedzerwa mukati nemateru akawanda emafuremu akachinjika akaiswa masefa.
Core Structure:
Sieve Case:Chimiro chesimbi chakareba mukati chakakamurwa kuva "makamuri."
Sieve Frames:Iyo yakakosha kushanda zvikamu. Furemu yega yega inobata masefa (sirika kana naironi) emhando dzakatarwa mesh, nemasaizi ekuvhura anowanzo kuve akatsetseka kubva kumusoro kusvika kuzasi. Zvinhu zvinofamba mukati memapuranga; madiki pane aperture "anopfuura," nepo makuru "anochengetwa."
Drive Mechanism:Kazhinji inofambiswa nemota yakamira pamusoro, ichigadzira kutenderera kwendege (yakafanana nematenderedzwa ekudhirowa) kuburikidza nemaredhi ekubvisa. Kufamba uku kunogovanisa zvinhu pamusoro pesefa pamusoro pekuti ibatane nemaapertures uku uchidzivirira kurovera kwakatwasuka (izvo zvinogona kukanganisa kurongeka kwaitwa).
Maitiro ekushanda:
Kudyisa:Ground stock inopinda kubva kumusoro, yakagoverwa kumakamuri akasiyana uye nzira dzekusefa.
Multi-layer Sifting:Material inofamba nepakati pemasero akaturikidzana sequentially pasi pe rotary motion.
Kuronga & Kuunganidza:Sieve yega yega inotsemura zvinhu kuita "overtails" (yakachengetwa) uye "kuburikidza" (yakapfuura). Overtails uye kuburikidza kubva kune akasiyana akaturikidzana uye nzira dzinounganidzwa kuburikidza nemukati chiteshi.
Discharge:Chekupedzisira, hova dzakawanda dzezvinhu zvakakamurwa (semuenzaniso, rudzi rweupfu, mhando mbiri dzesemolina, rudzi rumwe rwebran) dzinobuda panguva imwe chete kubva kune dzakasiyana siyana dziri pazasi uye dzinotakurwa nemapombi epneumatic kuenda kwadzinoenda.
IV. Key Technical Parameters uye Impact
Kuita kwe planifter kunoraira kushanda kwese kwegayo:
Sifting nzvimbo:Nzvimbo yakakura inowedzera huwandu uye inovimbisa kunyatsosefa. Iyo yakawanda-yakapetwa yakaturikidzana yePlansifter inopa nzvimbo yakakura yekusefa mukati meiyo compact tsoka, mukana wayo mukuru.
Sieve Configuration:Kusarudzwa uye kurongeka kwemaseve meshes (mesh kuverenga, zvinhu) ndiwo mweya wekugadzira dhizaini. Iyo inosarudza zvakananga kurongeka, kudhirowa kwemareshiyo ehova dzakasiyana, uye hupfu hwemhando.
Kusefa Kubudirira:Huwandu hwesefa-hupfu hunogona kuchekwa. Kushanda kwepamusoro kunoreva kudhirowa kwakanyanya, kuderedza kusingakodzeri kudzokororwa kwezvinhu, nekudaro kunowedzera chiyero chekubvisa uye kubuda.
Kumhanya & Eccentricity:Sarudza mafambiro ekumhanya uye trajectory pasefa, zvichikanganisa kusefa mhedzisiro uye kuyerera. Izvi zvinoda kugadziriswa zvichibva pane zvakasiyana siyana zvezvinhu.
V. Pfupiso: Iyo "Decision Center" yeMilling Process
Basa rePlansifter rinogona kunzwisiswa sedimikira:
Transportation Hub:Inotungamira posvo-kukuya "mixed traffic" (ground stock) pa "nzira" dzakasiyana zvichienderana ne "rudzi rwemota uye kwainoenda" (saizi nemhando), kuita kuti rwizi rwega-hwega rwufambe nemazvo kusvika panomira kunotevera.
Quality Control Point:Kuburikidza nemhando chaiyo, inoita kuti endosperm yakachena chete ipinde muhurongwa hwekudzikisa, zvichiita kuti pave nepamusoro-giredhi, yakaderera-hupfu hwemadota. Zvinodzivirirawo kudarika-kukuya bran, kuchengetedza hupfu husina kuchena.
Kiyi yekuburitsa & pundutso:Kusefa kugona kwePlansifter ndechimwe chezvipingamupinyi zvekuwedzera kubuda kweguyo. Kushanda kwayo, kwakagadzikana kushanda kwakakosha pakuwana hunyanzvi hwakagadzirirwa uye mwero wekutora.
Pasina Plansifter, kunyatsogadzirwa, kwakanyatsojeka, uye kunoenderera mberi kwechigayo chemazuva ano cheupfu kwaisazobvira. Yakamira yakanyarara muchigayo, inoita "mirayiridzo yekuronga" yakaoma uye chaiyo kuburikidza nezviuru zvemaburi emukati. Ndiyo imwe yeanonyanya kushandisa tekinoroji core links murwendo rwehupfu kubva pa "kugaya" kuenda ku "finished product."
