- 90% bilong ol lus bilong prodaksen i stap hait insait long ol dispela ditel
Wantaim wankain wit na wankain kain wit, bilong wanem sampela mil inap long kisim 78% 'extraction rate', na sampela i hatwok long kisim 73%? Olgeta 1 pesen poin difrens - bilong wanpela liklik plaua mil we i wok long prosesim 200 ton long wanwan de - i min olsem planti handet tausen yuan long lus bilong winmani long wanwan yia.
Long ol toktok bilong mipela wantaim planti handet 'flour mill', mipela i painim olsem planti ol papa bilong ol 'mill' i tok olsem ol i no kisim planti 'flour rates' bikos long "nogut kwaliti bilong wit." Tasol tok tru em planti taim:ol i no stretim gut ol ikwipmen, na ol paramita i no stret.
Ol dispela faivpela ki ikwipmen paramita i save mekim stret hamas veliu ol i kisim long olgeta wit. Plis sekim ol wan wan.
1. Rol Gap: Bikpela Swit bilong Brek Rilis
Impakt Lojik:
Rol gap i liklik tumas → bran i bruk na miks wantaim plaua, asis i go antap, plaua i kamap tudak
Rol gap i bikpela tumas → endosperm i no skrapim olgeta, bikpela 'starch' i stap yet long bran na ol i rausim, 'extraction rate' i go daun stret
Ki Data Refrens:
| Pasin bilong muv long wanpela ples i go long narapela | Rekomend Rol Gap (mm) | Taget Rilis Reit |
|---|---|---|
| 1B (Namba wan malolo) | 0.6-0.8 | 25%-35% |
| 2B | 0.4-0.6 | 45%-55% |
| 3B | 0.2-0.4 | 55%-65% |
Ol Gutpela Tip:
Yusim wanpelafeeler gaugeorol gap mitalong sekim pastaim long kirapim olgeta de
Harim krai bilong rol: sapos yu "klik" oltaim dispela i soim olsem spes i pas tumas
Lukluk long seip bilong ol 'bran flake': ol liklik hap bilong 'bran' i gutpela; paura i soim olsem em i tait tumas
2. Ples bilong Sivim na Skrin Konfiguresen: Ol i Sivim Gutpela Plaua Aut
Impakt Lojik:
I no gat inap hap bilong sevim → ol samting i stap long lain, gutpela plaua i no inap long seperet long taim na ol i karim i go long narapela hap bilong grisim → i kamapim wanpela "recirculating flour vicious cycle"
Skrin konfiguresen i no stret → plaua we i mas kam aut i no kam aut; ol liklik hap 'bran' we i no ken kamaut i save go insait long plaua
Ki Fomula:
Gutpela hap bilong sevim wit (m2)=Inap long prosesim wit long olgeta de (ton) × 0.8-1.0
Eksampel: Long 200 ton/de bilong wit, olgeta 'sieving area' bilong ol 'plansifters' i no ken liklik long160-200 m²
Planti rong:
Planti mil i save pasim sampela hap bilong sevim pawa bilong sevim pawa, na dispela i mekim na i no gat inap hap bilong sevim - dispela em inambawan hait kila bilong ekstraksen reit.
3. Presa bilong win na spit bilong win insait long 'pneumatic system': "Blood Vessel Helt" bilong 'Pneumatic Conveying'
Impakt Lojik:
Pneumatik sistem em i "blut rop" bilong wanpela 'flour mill'.
Inap win presa → paiplain i pas, ol samting i sindaun gut, prodaksen i stop
Spit bilong win i go antap tumas → ol liklik 'bran' i go insait long plaua, asis i go antap, 'extraction rate' i luk olsem i go antap tasol kwaliti i go daun
Ol bikpela data:
| Ples | Rekomend Air Velocity (m/s) | Wok |
|---|---|---|
| Ol paip bilong apim i go antap | 18-22 | Stopim ol samting long sindaun |
| Ol paip bilong karim samting i go stret | 16-18 | Noken bungim planti samting |
| Sistem bilong bungim das | 14-16 | Rausim das tasol |
Rot bilong sekim:
Tasim paip wantaim han bilong yu:liklik negatif presa(filing bilong sut) em i nomol
Putim wanpela hap pepa long dua bilong sekim: pepa i pulim i go insait i soim olsem i gat inap 'negative pressure'
Tempereja i antap tru long hap bilong mil → mak bilong win i no ron gut
4. Tempereja bilong rol: As bilong bagarap bilong 'starch' we ol i no luksave long en
Impakt Lojik:
Ol rol we i hat tumas → 'starch gelatinization', 'protein denaturation' → wok bilong kukim plaua i go daun → maski ol i rausim, em i no gutpela
Samting we i bikpela samting moa: ol hot rol i save mekim 'wheat endosperm' i kamap stret na i no save rausim, na dispela i save mekim wok bilong sevim i hat
Sefti Treshol:
Tempereja bilong pes bilong rol:Liklik o wankain olsem 55 digri(sapos yu inap tatsim rol wantaim baksait bilong han bilong yu inap 3-pela seken na yu no pilim olsem yu kukim, em i orait)
Tempereja bilong ol samting i go antap: noken winim 5-8 digri long wanwan taim
Ol samting bilong mekim i kol:
Sekim 'cooling water flow rate' na tempereja (wara i kam insait i no winim o wankain olsem 25 digri)
Noken taitim tumas 'roll gap' we i save kamapim 'friction heat'
Bihain long 4-pela aua bilong wok yet, larim ol rol i ran nating inap 15 minit long kol daun
5. Tempering Moisture and Damping System: Laspela Step bilong Mekim Bran i kamap malumalum
Impakt Lojik:
Nogat inap wara long mekim 'bran' i kamap strong na bruk bruk → 'bran' i bruk i go insait long plaua
Planti wara i mekim 'endosperm' i pas long 'bran' na ol i no inap rausim skin bilong en → 'extraction rate' i go daun
Ol gutpela mak:
| Kain wit | Taget Tempering Moisture | Taim bilong daunim |
|---|---|---|
| Strongpela retpela wit | 15.5%-16.5% | 18-24 aua |
| Sof waitpela wit | 14.5%-15.5% | 12-16 aua |
Ol bikpela samting bilong sekim:
Damping kontrol sistem i no ken winim ±0.3%
Ol 'tempering bin' i mas gatotomatik bin tanimoplanti discharge poinbilong stopim wara long bruk bruk
Laspela 'damping' (laspela taim ol i putim pastaim long 'milling') i no ken winim 1.5%, sapos nogat, ol samting inap long slip
[Self-Check Checklist]
Sapos 'extraction rate' bilong mil bilong yu i no gutpela, mipela i rekomendim yu long stretim hevi long dispela oda:
□ Skelim trupela 'roll gap' bilong 1B i go long 3B wantaim wanpela 'roll gap meter'
□ Kalkuletim sapos eria bilong wok sivim i stret long mak
□ Sekim negatif presa insait long ol ki paip long rot bilong 'feel' o wantaim wanpela 'anemometer'
□ Skelim temperaja bilong rol bihain long 1 aua bilong wok yet
□ Salim ol sempel bilong sekim trupela wara bilong wit bihain long ol i tanim
Planti taim, em i no olsem ol ikwipmen i bagarap - tasol ol paramita i no wok gut.
