Production Loss - 90% chu Heng Details-ah hian Thup A ni
Wheat inang leh chi inang chiah a awm chuan engvangin nge mill thenkhatin extraction rate 78% an neih theih a, thenkhat erawh chuan 73% thleng turin an beih theih? Ni khata ton 200 processing flour mill tenau pakhat tan percentage point 1 inthlauhna - apiang - hian kum khata hlawkna hloh yuan sang tam tak a awm tihna a ni.
Flour mill za tam tak nena kan inthlengnaah hian mill neitu tam tak chuan extraction rate hniam hi "wheat quality tha lo" vang niin an sawi. Mahse thudik chu hetiang hi a ni fo thin:hmanrua chu a insiamrem tha lo va, parameter pawh a set dik lo bawk.
A hnuaia key equipment parameter pangate hian buh chi khat atanga value lak chhuah zat chu direct-in a nghawng a ni. Pakhat hnu pakhatin lo check ve dawn nia.
1. Roll Gap: Break Release-a Master Switch a ni
Impact Logic chu: 1.1.
Roll gap a tlem lutuk → bran a chhe a, flour-ah a inhmeh a, ash content a sang a, flour a thim bawk
Roll gap a lian lutuk → endosperm chu a scrape off kim lo va, starch nasa tak chu bran-ah a awm reng a, sieved out a ni a, extraction rate chu direct-in a tlahniam
Data pawimawh tak takte chu:
| Kalkawng | Roll Gap (mm) hman dan tur ruahman . | Target Release Rate a ni |
|---|---|---|
| 1B (Chawlh hmasa ber) . | 0.6-0.8 | 25%-35% |
| 2B | 0.4-0.6 | 45%-55% |
| 3B | 0.2-0.4 | 55%-65% |
Tips tangkai tak tak:

Roll sound ngaithla rawh: "click" chhunzawm zel chuan gap a tight lutuk tih a tilang
Bran flake pianzia enfiah rawh: intact thin flakes hi a tha ber; powder hian a tight lutuk tih a tilang
2. Sieving Area leh Screen Configuration: Flour tha tak chu Sieved Out a ni
Impact Logic chu: 1.1.
Sieving area tling lo → material queue up, flour tha tak chu a hun takah a inthen thei lo va, a hnuaia grinding pass-ah a kalpui → "recirculating flour vicious cycle" a siam a ni.
Screen configuration dik lo → flour chhuak tur chu a chhuak lo; bran specks chhuak lo tur chu flour-ah a tawp ta a ni
Formula pawimawh tak tak:
Sieving area remchang (m2)=Nitin buhfai siam chhuah theihna (tons) × 0.8-1.0
Entirnan: Wheat ton 200/ni atan chuan plansifter-te sieving area zawng zawng chu a tlem lo tur a ni160-200 m²
Thil tihsual tlanglawn:
Mill tam tak chuan electric humhalh nan sieve compartment thenkhat an off a, chu chuan sieving area tling lo - this is theextraction rate-a killer thup ber.
3. Pneumatic System-a Air Pressure leh Velocity: Pneumatic Conveying-a "Blood Vessel Health" tih hi a ni
Impact Logic chu: 1.1.
Pneumatic system hi flour mill-a "thisen kalna" a ni.
Air pressure tling lo → pipeline block, material settling, production tihtawp
Air velocity tam lutuk → fine bran chu flour-ah an suck a, ash content a sang a, extraction rate chu inflated angin a lang a mahse quality a tlahniam thung
Data pawimawh tak tak:
| Hmun | Thli chakna (m/s) rawtna 1.1. | Thiltih |
|---|---|---|
| Vertical lift pipe hmanga siam a ni | 18-22 | Material settling lo turin venhim rawh |
| Horizontal conveying pipe te chu a awm a | 16-18 | Material khawlkhawm hi pumpelh rawh |
| Dust khawlkhawm dan tur | 14-16 | Dust chauh extract rawh |
Enfiah dan tur: 1.1.
Pipe chu i kutphah hmangin khawih rawh:negative pressure tlem a awm bawk(suction feeling) hi thil pangngai a ni
Inspection kawngka bulah lehkha pakhat dah la: paper suck luh hian negative pressure tling a nih thu a tarlang
Mill area-a boruak lum dan pangngai lo → boruak kal tlem dan chhinchhiahna tlangpui
4. Roll Temperature: Starch chhiatna thlentu ngaihthah
Impact Logic chu: 1.1.
Roll lum lutuk → starch gelatinization, protein denaturation → flour baking performance tihhniam → sieved out pawh nise, a substandard
A pawi zawk chu: hot rolls hian wheat endosperm chu a flake off ai chuan a flatten a, chu chuan a hnu lama sieving a ti harsa hle

Darkar 4 chhung zet siam chhunzawm zel hnuah rolls te chu minute 15 chhung idle-a kal tir la, a lum theih nan
5. Tempering Moisture leh Damping System: Bran tih nemna atana hmalakna hnuhnung ber
Impact Logic chu: 1.1.
Tempering moisture tling lo → bran chu a khauh a, a chhe bawk → bran chhe tawh chu flour-ah a inhmeh lo
Tempering moisture tam lutuk → endosperm chu bran-ah a innghat a, a peel off thei lo → extraction rate a tlahniam
Range tha ber berte:
| Wheat chi hrang hrang | Target Tempering Moisture a ni | Tempering Hun a ni |
|---|---|---|
| Wheat sen khauh tak a ni | 15.5%-16.5% | Darkar 18-24 chhung a ni |
| Wheat dum nêm tak | 14.5%-15.5% | Darkar 12-16 chhung a ni |
Thil hmanraw pawimawh tak tak enfiahna hmun:

I mill-a extraction rate a lungawi loh chuan a hnuaia order ang hian troubleshooting kan rawt a che:
□ Roll gap meter hmangin 1B atanga 3B thlenga roll gap tak tak chu teh rawh
□ Operating sieving area tak tak chuan standard a tlin leh tlin loh chhut rawh
□ Key pipe-a negative pressure chu feel emaw, anemometer emaw hmangin enfiah rawh
□ Roll temperature chu darkar 1 chhunga siam chhunzawm zel hnuah teh tur a ni
□ Tempering hnuah wheat moisture tak tak test turin sample thawn tur a ni
Vawi tam tak chu hmanrua a chhiat vang a ni lo - parameters a drift vang zawk a ni.
