- 90% ntawm kev poob ntau lawm raug muab zais rau hauv Cov Lus Qhia no
Nrog tib hom nplej thiab tib yam, vim li cas qee lub mills tuaj yeem ua tiav qhov kev rho tawm ntawm 78%, thaum lwm tus tawm tsam kom ncav cuag 73%? Txhua 1 feem pua ntawm qhov sib txawv - rau cov hmoov nplej me me ua 200 tons hauv ib hnub - txhais tau tias ntau pua txhiab yuan hauv cov nyiaj tau los txhua xyoo.
Hauv peb cov kev sib pauv nrog ntau pua ntawm cov hmoov nplej, peb tau pom tias ntau tus tswv zeb ntaus nqi qis qis rau "cov nplej tsis zoo." Tab sis qhov tseeb yog feem ntau:cov khoom siv tsis raug kho kom raug, thiab cov kev txwv tsis raug teeb tsa.
Cov nram qab no tsib yam khoom tseem ceeb tsis cuam tshuam ncaj qha rau tus nqi npaum li cas muab rho tawm los ntawm txhua cov nplej nplej. Thov txheeb xyuas lawv ib leeg.
1. Roll Gap: Tus Tswv Hloov ntawm Kev Tso Tawm
Impact Logic:
Yob qhov sib txawv me me dhau → bran tawg thiab sib tov rau hauv hmoov, hmoov tshauv nce, hmoov nplej darkens
Yob qhov sib txawv loj heev → endosperm tsis yog tag nrho scraped tawm, tseem ceeb hmoov txhuv nplej siab tseem nyob rau hauv bran thiab yog sieved tawm, extraction tus nqi poob ncaj qha
Cov ntaub ntawv tseem ceeb:
| Txoj kev | Pom zoo Roll Gap (mm) | Lub Hom Phiaj Tshaj Tawm |
|---|---|---|
| 1B (thawj zaug) | 0.6-0.8 | 25%-35% |
| 2B | 0.4-0.6 | 45%-55% |
| 3B | 0.2-0.4 | 55%-65% |
Tswv yim tswv yim:
Siv antsuas ntsuaslos yogyob gap meterlos xyuas ua ntej pib ua haujlwm txhua hnub
Mloog lub suab yob: tsis tu ncua "nias" qhia tias qhov sib txawv yog nruj heev
Saib cov duab ntawm bran flakes: zoo li nyias flakes; hmoov qhia tias nruj nruj heev
2. Sieving Area thiab Screen Configuration: Cov hmoov nplej zoo yog Sieved tawm
Impact Logic:
Tsis txaus sieving cheeb tsam → cov khoom queues, hmoov zoo tsis tuaj yeem sib cais nyob rau hauv lub sij hawm thiab nqa mus rau tom ntej sib tsoo pass → ua ib tug "recirculating hmoov vicious voj voog"
Kev teeb tsa tsis zoo ntawm lub vijtsam → cov hmoov nplej uas yuav tsum tawm tsis tau; bran specks uas yuav tsum tsis txhob tawm mus rau hauv hmoov
Cov qauv tseem ceeb:
Tsim nyog sieving cheeb tsam (m²)=Txhua hnub nplej ua muaj peev xwm (tons) × 0.8-1.0
Piv txwv li: Rau 200 tons / hnub ntawm cov nplej, tag nrho cov sieving cheeb tsam ntawm planifters yuav tsum tsis txhob tsawg tshaj li160-200 m²
Feem ntau yuam kev:
Ntau lub mills tua ib co sieve compartments kom txuag hluav taws xob, ua rau tsis txaus sieving cheeb tsam - qhov no yog qhovfeem ntau zais killer ntawm rho tawm tus nqi.
3. Cua Siab thiab Tshaj Tawm hauv Pneumatic System: "Kev Noj Qab Haus Huv Ntshav" ntawm Pneumatic Conveying
Impact Logic:
Lub tshuab pneumatic yog "cov hlab ntsha" ntawm cov hmoov nplej.
Tsis txaus cua siab → pipeline blockage, khoom daws teeb meem, kev cuam tshuam ntau lawm
Huab cua tshaj tawm → nplua bran yog nqus mus rau hauv cov hmoov nplej, hmoov tshauv cov ntsiab lus nce, qhov rho tawm zoo li inflated tab sis tsis zoo
Cov ntaub ntawv tseem ceeb:
| Qhov chaw | Pom zoo cua nrawm (m / s) | Muaj nuj nqi |
|---|---|---|
| Vertical nqa kav | 18-22 | Tiv thaiv kom tsis txhob muaj teeb meem ntawm cov khoom |
| Kab rov tav conveying kav | 16-18 | Tsis txhob muab cov khoom sib xyaw |
| Plua plav qhov system | 14-16 | Extract tsuas hmoov av |
Kev tshuaj xyuas:
Kov cov yeeb nkab nrog koj xib teg:me ntsis tsis zoo siab(suction xav) yog qhov qub
Muab ib daim ntawv tso rau ntawm lub qhov rooj tshuaj ntsuam: daim ntawv raug nqus hauv qhov qhia tias muaj qhov tsis zoo txaus
Qhov kub tsis txawv txav hauv thaj tsam zeb → cov cim qhia ntawm cov cua tsis txaus
4. Roll Temperature: Lub Overlooked Ua rau Starch puas
Impact Logic:
Overheated yob → starch gelatinization, protein denaturation → txo hmoov ci kev ua tau zoo → txawm tias sieved tawm, nws yog substandard
Xav paub ntau ntxiv: kub rolls flatten cov nplej endosperm es tsis txhob flaking nws tawm, ua rau tom ntej sieving nyuaj
Safety Threshold:
Roll nto kub:Tsawg dua lossis sib npaug li 55 degree(yog tias koj tuaj yeem kov lub yob nrog nraub qaum ntawm koj txhais tes rau 3 vib nas this yam tsis muaj qhov kub hnyiab, nws tau txais)
Cov khoom kub nce: tsis pub ntau tshaj 5-8℃ib kis
Kev ntsuas cua txias:
Txheeb xyuas cov dej txias ntws thiab qhov kub thiab txias (cov dej tuaj tsawg dua lossis sib npaug li 25 degree)
Tsis txhob sib sib zog nqus ntau dhau uas ua rau muaj kev sib txhuam kub
Tom qab 4 teev ntawm kev tsim khoom tas mus li, cia cov yob khiav tsis ua haujlwm rau 15 feeb kom txias
5. Tempering Moisture thiab Damping System: Qhov kawg kauj ruam kom Soften Bran
Impact Logic:
Tsis txaus tempering noo noo → bran ua nyuaj thiab nkig → tawg bran sib tov rau hauv hmoov
Ntau dhau tempering noo noo → endosperm sticks rau bran thiab tsis tuaj yeem tev tawm → rho tawm tus nqi poob
Optimal Ranges:
| Hom Nplej | Target Tempering Moisture | Tempering Sijhawm |
|---|---|---|
| Nplej liab | 15.5%-16.5% | 18-24 teev |
| Mos dawb nplej | 14.5%-15.5% | 12-16 teev |
Cov Khoom Siv Tseem Ceeb Checkpoints:
Damping tswj qhov hloov pauv yuav tsum tsis pub tshaj ± 0.3%
Tempering bins yuav tsum tau nruab nrogautomatic bin turnerslos yogntau cov ntsiab lus tso tawmkom tsis txhob ya raws stratification
Qhov kawg damping (kawg ntxiv ua ntej milling) yuav tsum tsis txhob ntau tshaj 1.5%, txwv tsis pub cov khoom slippage yuav tshwm sim
[Tus kheej-Cov Ntawv Tshawb Xyuas]
Yog tias koj lub zeb rho tawm tus nqi tsis txaus siab, peb pom zoo kom daws teeb meem raws li hauv qab no:
□ Ntsuas qhov sib txawv ntawm qhov tseeb ntawm 1B txog 3B nrog lub ntsuas qhov sib txawv
□ Xam seb qhov chaw ua haujlwm sieving tiag tiag puas tau raws li tus qauv
□ Txheeb xyuas qhov tsis zoo ntawm cov kav dej tseem ceeb los ntawm kev xav lossis nrog lub ntsuas qhov ntsuas
□ Ntsuas qhov kub ntawm qhov yob tom qab 1 teev ntawm kev tsim khoom tas mus li
□ Xa cov qauv los kuaj cov hom qoob loo tiag tiag tom qab tempering
Feem ntau, nws tsis yog tias cov cuab yeej tawg lawm - nws yog qhov tsis muaj drifted.
