Lub Plansifter yog lub hauv paus, lub plawv, ntawm seem milling nyob rau hauv ib tug niaj hnub hmoov zeb. Nws qhov kev ua haujlwm tau zoo ncaj qha txiav txim siab lub zeb qhov kev rho tawm, lub peev xwm ntau lawm, cov khoom zoo, thiab kev ruaj ntseg ntau lawm.
Yog tias lub tshuab zeb yog "tus kws tshaj lij kev sib tsoo," ces Plansifter yog "precision sorting master." Cov nram qab no qhia meej nws daim ntawv thov nyob rau hauv ib tug hmoov zeb.
I. Lub Hom Phiaj Tseem Ceeb: Sifting thiab Classification
Lub hom phiaj tseem ceeb ntawm Plansifter yog ua kom tsis tu ncua, ua tau zoo, thiab meej meej sift thiab faib cov "hauv av" los ntawm cov menyuam mills (ie, ncej- sib tov sib xyaw uas muaj cov hmoov nplej ntawm ntau qhov ntau thiab tsawg, bran, endosperm hais, thiab lwm yam).
Extracting tiav hmoov nplej:Nws cais qhov zoo tshaj plaws, kev qhia tshwj xeeb- ua raws cov hmoov nplej (feem ntau hu ua "mesh" lossis "μm") los ntawm kev sib tov, coj lawv ua tiav hmoov nplej mus rau cov txheej txheem tom ntej (xws li, tswj kev sib tov, ntim, lossis hmoov nplej sib xyaw).
Kev faib khoom siv:Nws faib cov khoom loj dua uas tseem tsis tau zoo txaus los ua hmoov nplej rau hauv cov qib sib txawv raws li qhov loj thiab qhov zoo (xws li cov ntsiab lus bran), xws li:
Semolina / Coarse Midlings:Loj, ntshiab endosperm hais.
Fine Bran / Coarse Bran:Bran hais nqa ib qho me me ntawm endosperm.
Coarse Bran:Loj bran flakes.
Kev faib khoom siv:Nws precisely txoj kev txhua kwj cais mus rau nws cov txheej txheem tom ntej ua tshuab, yog li tsim tag nrho cov milling ntws.
II. Txoj hauj lwm thiab lub luag haujlwm hauv Mill Process Flow
Lub Plansifter tsis ua haujlwm hauv kev sib cais. Nws yog ua ke nrog cov menyuam mills los ua "sib tsoo-sifting" voj units. Tag nrho cov txheej txheem milling yog ib qho ntawm cov khoom sib txuas.
Hom txheej txheem Loop:
Roller Mill (sib tsoo) → Plansifter (Sifting/Classification) → Classified kwj → Xa mus rau lwm yam -stage Roller Mills los yog Purifiers → Regrinding → Back to the Plansifter...
Lub voj voog no rov ua dua, ua haujlwm zoo li cov kab sib dhos ua tau zoo, ua ntu zus thiab ua kom cov nplej endosperm los ntawm bran.
Qhov System Layout:Hauv 100-tuj / hnub hmoov nplej, ntau Plansifters feem ntau lis sifting rau txawv "systems," piv txwv li:
Break System Plansifters:Cov txheej txheem cov ntaub ntawv los ntawm thaum ntxov so rolls. Lawv lub luag haujlwm tseem ceeb yog txhawm rau rho tawm cov hmoov nplej ntau ntau thiab cais cov bran los ntawm ntxhib thiab nplua middlings.
Txo qhov System Plansifters:Cov txheej txheem cov khoom siv los ntawm kev txo cov yob. Lawv txoj haujlwm yog kev sib tsoo zoo thiab sifting ntawm cov ntshiab endosperm kom rho tawm qib siab - qib hmoov.
Sizing System Plansifters:Cov txheej txheem cov ntaub ntawv los ntawm sizing rolls. Lawv txoj hauj lwm yog los kho cov kab mob endosperm nrog tsawg kawg nkaus bran txuas, rau kev ua kom huv ntxiv thiab hmoov nplej extraction.
III. Txoj Cai Ua Haujlwm thiab Cov Txheej Txheem Ua Haujlwm
Lub Plansifter (lub npe tag nrho: High Square Horizontal Plansifter) tau txais nws lub npe los ntawm nws qhov siab, square txee -zoo li cov qauv, sab hauv stacked nrog ntau txheej ntawm kab rov tav tso sieve thav ntawv.
Core Structure:
Sieve Case:Lub siab steel qauv sab hauv muab faib ua "compartments."
Sieve Frames:Cov khoom tseem ceeb ua haujlwm. Txhua thav duab tuav sieves (silk lossis nylon) ntawm cov mesh tshwj xeeb, nrog rau qhov ntau thiab tsawg feem ntau ua finer los ntawm sab saum toj mus rau hauv qab txheej. Cov khoom txav mus rau hauv cov ncej; cov khoom me dua qhov aperture "dhau mus," thaum cov loj dua yog "tso tseg."
Tsav Mechanism:Feem ntau siv los ntawm lub cev muaj zog ntsug nyob rau sab saum toj, tsim lub dav hlau teb cov lus tsa suab (zoo ib yam li kos duab voj voog) ntawm qhov hnyav offset. Cov lus tsa suab no sib npaug faib cov khoom hla lub sieve nto rau kev sib cuag nrog apertures thaum tsis txhob ntsug bouncing (uas tuaj yeem cuam tshuam kev faib ua tiav).
Txheej txheem ua haujlwm:
Pub mis:Cov khoom hauv av nkag los ntawm sab saum toj, faib rau cov khoom sib txawv thiab sifting txoj hauv kev.
Multi-layer Sifting:Cov khoom txav los ntawm cov sieve khaubncaws sab nraud povtseg nyob rau hauv lub rotary motion.
Classification & Collection:Txhua lub sieve faib cov khoom rau hauv "overtails" (tso tseg) thiab "dhau" (dhau). Overtails thiab dhau los ntawm cov khaubncaws sab nraud povtseg thiab cov kev sib txawv yog sau los ntawm cov channel sab hauv.
Tshem tawm:Thaum kawg, ntau cov kwj ntawm cov khoom siv (piv txwv li, ib hom hmoov nplej, ob hom semolina, ib hom bran) tawm ib txhij los ntawm ntau qhov hluav taws xob hauv qab thiab raug thauj los ntawm cov kav dej pneumatic mus rau lawv qhov chaw.
IV. Ntsiab Technical Parameters thiab Impact
Plansifter qhov kev ua tau zoo dictates cov efficiency ntawm tag nrho cov txheej txheem milling:
Sifting cheeb tsam:Ib cheeb tsam loj tuaj yeem ua kom muaj peev xwm thiab ua kom tiav sifting. Cov txheej txheem ntau- txheej txheej ntawm Plansifter muab thaj chaw loj sifting nyob rau hauv ib qho kev cog lus, nws qhov zoo tshaj plaws.
Sieve Configuration:Kev xaiv thiab kev npaj ntawm sieve meshes (mesh suav, khoom siv) yog tus ntsuj plig ntawm cov txheej txheem tsim. Nws ncaj qha txiav txim siab qhov tseeb ntawm kev faib tawm, kev rho tawm piv rau ntau cov kwj deg, thiab hmoov zoo.
Sifting Efficiency:Qhov feem pua ntawm sieve - tau hmoov tau muab rho tawm. Kev ua haujlwm siab txhais tau tias qhov siab tshaj plaws rho tawm, txo cov khoom siv tsis tsim nyog rov ua dua, yog li txhawb nqa tus nqi rho tawm thiab tso tawm.
Ceev & eccentricity:Txiav txim siab cov khoom txav ceev thiab trajectory ntawm lub sieve, cuam tshuam sifting tau thiab ntws. Cov no xav tau kev hloov kho raws li cov khoom sib txawv.
V. Summary: "Lub Chaw Txiav Txim Siab" ntawm Cov Txheej Txheem Milling
Lub luag haujlwm ntawm Plansifter tuaj yeem nkag siab piv txwv:
Tsheb thauj mus los Hub:Nws coj tus ncej- sib tsoo "kev sib xyaw tsheb" (hauv av Tshuag) mus rau qhov "txoj kab" cais raws li "tsheb hom thiab qhov chaw" (qhov loj me thiab qhov zoo), ua kom txhua tus kwj tawm mus rau qhov chaw nres tsheb tom ntej.
Quality Control Point:Los ntawm kev faib tawm meej, nws ua kom ntseeg tau tias tsuas yog cov endosperm ntshiab nkag mus rau hauv qhov txo qis, ua kom muaj cov qib siab -qib, qis- hmoov tshauv. Nws kuj tseem tiv thaiv tshaj - sib tsoo ntawm bran, tiv thaiv hmoov purity.
Qhov tseem ceeb rau Kev Tshaj Tawm & Tshaj Tawm:Lub peev xwm sifting ntawm Plansifter yog ib qho tseem ceeb ntawm lub fwj rau kev ua kom lub tshuab tso zis ntau ntxiv. Nws ua haujlwm tau zoo, ruaj khov yog qhov tseem ceeb kom ua tiav qhov tsim muaj peev xwm thiab rho tawm tus nqi.
Yog tsis muaj Plansifter, qhov ua tau zoo, meej, thiab txuas ntxiv ntawm cov hmoov nplej niaj hnub yuav ua tsis tau. Sawv ntsiag to nyob rau hauv lub zeb, nws executes complex thiab meej "sorting cov lus qhia" los ntawm nws phav phav ntawm sab hauv sieve apertures. Nws yog ib qho ntawm cov thev naus laus zis tseem ceeb tshaj plaws txuas hauv cov hmoov zeb txoj kev taug kev los ntawm "sib tsoo" mus rau "cov khoom tiav."
