Qhov tsis sib xws extrusion zoo ntawmfloating ntses pub pellet extruder tshuab(qhov sib txawv tseem ceeb hauv extrusion tus nqi, shaping, thiab tsos ntawm batches) ua rau cov khoom tsis zoo, ua rau lub npe nrov npe thiab ua rau cov nqi rov ua dua thiab cov nqi seem.
Paub meej
I. Tshwj xeeb Phenomena ntawm Unstable Extrusion Zoo
Phenomenon Description:
- Variation hauv Extrusion Rate:Qhov sib txawv tseem ceeb hauv extrusion tus nqi (ntau tshaj 10%) ntawm cov khoom siv. Qee cov batch tej zaum yuav nyob rau hauv - nthuav dav, thaum lwm tus dhau - nthuav.
- Cov teeb meem tsim:Qhov zoo ntawm shaping yog inconsistent, nrog rau ib co batch ua tsis tu ncua, tsis zoo hais, thaum lwm tus ua rau cov duab tsis zoo los yog tawg.
- Cov tsos mob hloov pauv:Batches sib txawv nyob rau hauv tsos zoo. Qee qhov yuav muaj qhov tsis xws luag -dawb, thaum lwm tus pom qhov chaw hlawv, xim txawv, lossis burrs.
- Saj thiab ntom Variability:Saj, kev ntxhib los mos, thiab qhov ntom ntom qhia qhov sib txawv ntawm cov khoom sib txawv, ua rau tsis zoo rau cov qauv thiab cov kev xav tau zoo ntawm cov khoom.
II. Cov laj thawj tseem ceeb ntawm Puffing tsis ruaj khov
1. Ntau dhau Batch Variation hauv Raw Materials (50%)
- Raw Material Sib txawv:Kev hloov pauv ntawm cov dej noo, qhov loj me, cov hmoov txhuv nplej siab / cov ntsiab lus ntawm cov protein, thiab tshwj xeeb tshaj yog qhov piv ntawm amylose rau amylopectin hauv cov khoom siv hmoov txhuv nplej siab ua rau muaj qhov sib txawv loj. Tsis tas li ntawd, kev cia khoom tsis sib xws (humidity, kub) tuaj yeem cuam tshuam rau cov khoom siv raw, xws li kev nqus dej noo, pwm loj hlob, lossis fatty acid oxidation.
- Kev cuam tshuam rau Puffing:Thaum cov yam ntxwv ntawm raw khoom sib txawv los ntawm batch mus rau batch, cov txheej txheem puffing ua inconsistent. Yog tsis muaj kev hloov kho sai rau cov txheej txheem tsis tu ncua tom qab hloov cov khoom siv raw, puffing zoo fluctuates drastic.
2. floating ntses pub pellet ua tshuab Parameter Fluctuations (30%)
- Chav Siab & Flow Instability:Kev hloov pauv hauv chav siab thiab cov nqi ntws ua rau qhov kub thiab txias tsis txaus hauv lub tshuab chamber, cuam tshuam cov txheej txheem puffing.
- Cov cuab yeej tsis sib xws:Qhov tsis sib xws hauv kev pub mis ceev, ceev ceev, thiab qhov ntsuas kub tuaj yeem cuam tshuam rau cov khoom siv gelatinization thiab puffing, ua rau batch - mus rau -batch inconsistency.
- Uncalibrated Instruments:Kev ncua kev ntsuas kub ntawm cov tswj ntsuas kub, ntsuas ntsuas, lossis lwm yam ntsuas ntsuas ua rau muaj kev nyeem ntawv yuam kev, ua rau tsis raug qhov ntsuas qhov ntsuas thiab cuam tshuam qhov sib xws.
3. Kev tu tsis txaus ntawm Floating Fish Food Production Machine (15%)
- Hnav ntawm Cov Khoom Tseem Ceeb:Kev hnav tsis sib xws ntawm cov khoom xws li cov ntsia hlau, lub tes tsho, thiab tuag ua rau cov khoom siv tau hloov pauv. Qhov no ua rau cov khoom tsis sib xws extrusion, sib txawv puffing zoo, thiab ntau zaus ntau lawm defects.
- Lubrication thiab Cooling System Teeb meem:Kev ua haujlwm tsis zoo hauv lub tshuab lubrication lossis cua txias tuaj yeem ua rau muaj kev hloov pauv hauv cov ntsia hlau ceev, qhov kub thiab txias, thiab extrusion siab, cuam tshuam rau cov txheej txheem puffing.
- Residual Material Tsim-up:Kev tu tsis raug tom qab txhua pawg tuaj yeem ua rau cov khoom seem hauv cov khoom sib xyaw nrog cov khoom tshiab, ua rau muaj kev sib kis, cuam tshuam tsis zoo, thiab qhov tsis zoo ntawm cov tsos thiab kev ntxhib los mos.
4. Tsis yog -Txoj Haujlwm Kev Ua Haujlwm thiab Kev Tswj Xyuas Txheej Txheem (5%)
- Cov kev ua haujlwm tsis sib xws:Kev hloov pauv hauv cov neeg ua haujlwm lossis tsis ua raws li cov txheej txheem txheej txheem thaum lub sijhawm tsim khoom tuaj yeem ua rau muaj kev hloov pauv hauv kev tswj cov txheej txheem. Kev hloov pauv tsis sib xws kuj tseem ua rau batch-rau-batch variation.
- Tsis muaj cov ntaub ntawv ntau lawm:Yog tsis muaj cov ntaub ntawv ntxaws ntxaws, nws nyuaj rau kev taug qab thiab daws cov teeb meem zoo, ua rau nws nyuaj rau kev ua kom zoo dua rau cov khoom siv yav tom ntej.
III. Kev daws teeb meem tsis ruaj khov Puffing Zoo thiab Standardized Control
1. Raw Material Standardization Management
- Raw Material Testing:Ua raws li kev ntsuas cov khoom siv raw ua ntej txhua pawg, tshuaj xyuas cov dej noo, qhov loj me, thiab cov ntsiab lus ntawm cov hmoov txhuv nplej siab / cov protein kom ntseeg tau tias ua raws li cov qauv tsim khoom.
- Standardized Cia ib puag ncig:Khaws qhov chaw qhuav, zoo - qhov chaw cia qhov cua kom tsis txhob muaj cov khoom nyoos los ntawm kev nqus dej los yog ua pwm.
- Batch Kho:Tom qab kev hloov pauv ntawm cov khoom siv raw, ua ib qho me me - batch sim khiav los kho cov txheej txheem tsis ua ntej tag nrho - nplai ntau lawm, kom ntseeg tau qhov sib xws.
2. ntab ntses noj ua tshuab Parameter Stability Control
- Siab Stabilization:Txhim kho lub siab ruaj khov cov cuab yeej kom tswj tau qhov sib npaug ntawm qhov siab thiab cov nqi ntws, ua kom cov txiaj ntsig ruaj khov puffing.
- Automated Tswj System:Ua kom muaj kev siv lub tshuab ua kom tsis muaj zog los tswj kev pub mis ceev, ntsia hlau ceev, thiab milling kub, txo tib neeg kev ua yuam kev thiab ua kom cov txheej txheem sib xws.
- Regular Calibration:Xyuas kom meej tias qhov ntsuas kub, ntsuas ntsuas, thiab lwm yam ntsuas ntsuas tau ntsuas tsis tu ncua, nrog kev tswj tsis raug nyob rau hauv ± 5℃ntau yam.
3. Routine floating ntses noj pellet txiag tshuab Kho
- Kev tshuaj xyuas txhua hnub thiab kev tu lub sijhawm:Tsim kom muaj kev soj ntsuam txhua hnub rau cov khoom tsis zoo (ntsia hlau, lub tes tsho, tuag), thiab teem caij rau hauv - kev saib xyuas qhov tob peb lub hlis twg los hloov cov khoom hnav tam sim ntawd.
- Ncej -Kev tu ntau lawm:Tom qab txhua qhov kev tsim tawm, ntxuav cov cuab yeej kom huv si, suav nrog cov tuag, manifolds, thiab cov ntsia hlau, txhawm rau tiv thaiv kev sib kis ntawm cov khoom sib kis.
- Lubrication thiab Cooling System Check:Tsis tu ncua xyuas cov lubrication thiab txias tshuab kom paub tseeb tias lawv ua haujlwm zoo thiab muab kev ua haujlwm ruaj khov thaum lub sijhawm tsim khoom.
4. Txuj kev ua haujlwm thiab kev tswj cov ntaub ntawv
- Kev cob qhia neeg ua haujlwm:Muab kev cob qhia kev cob qhia rau cov neeg ua haujlwm kom paub meej cov txheej txheem kev ua haujlwm raws li kev ua raws, txo qhov kev pheej hmoo ntawm tib neeg yuam kev.
- Batch Production Records:Khaws cov ntaub ntawv ntxaws ntxaws uas suav nrog cov khoom siv raw, cov txheej txheem tsis ua haujlwm, thiab cov khoom siv rau txhua pawg. Qhov no ua rau nws yooj yim dua los taug qab cov teeb meem thiab txhim kho qhov tsis zoo.
- Kev txheeb xyuas cov ntaub ntawv thiab txheej txheem optimization:Tsis tu ncua soj ntsuam cov ntaub ntawv zoo batch los txheeb xyuas cov qauv thiab txhim kho cov khoom lag luam kom zoo dua qub.
