I. Ceev nrooj txheeb xyuas hom teeb meem (ntawm -kev ntsuas qhov chaw hauv 5 feeb)
Siv qhov "saib, ntsuas, kos" peb -kauj ruam txoj hauv kev los taw qhia qhov laj thawj ntawm kev ntxuav qhov txawv txav:
1. Saib xyuas qhov xwm txheej
Overflow yog turbid los yog muaj hais? → Kev tu tsis tiav lossis qhov seem seem thaiv
Underflow yog columnar lossis dripping? → Local blockage
Cov cuab yeej to lossis kev co? → Cov qauv kev puas tsuaj los ntawm kev ntxuav
2. Ntsuas qhov ntsuas
Puas yog pub siab ntau dua los yog sib npaug li 10%?
Puas yog pH ntawm cov dej ntws tawm ntawm qhov nruab nrab (6.5-7.5)?
Is the final stage starch milk protein content >0.55%?
3. Tshawb xyuas cov ntaub ntawv
Has the cleaning period expired (>500 teev yam tsis muaj disassembly thiab tshuaj xyuas)?
Puas yog kev ntxuav tob tsis tau ua tom qab hloov cov khoom siv raw?
✅ Tswv yim: Raws li Wuxi lub zos "Food Safety Risk Management List," txhua yam kev tu huv si yuav tsum tau sau tseg thiab taug qab.
II. Cov lus teb ceev ceev rau cov teeb meem tshwm sim (Sorted by Priority)
1. Kev thaiv tsis tu ncua tom qab ntxuav: Cov yeeb nkab tshem tawm tam sim + Siab siab -Txoj kev ntws tawm
Cov kauj ruam ua haujlwm:
Nres lub tshuab thiab qhib lub qhov dej ntws tawm kom ntws cov kua seem ntawm qhov system.
Disassemble lub hydrocyclone los ua ke thiab tsau rau hauv 5% NaOH tov rau 1-2 teev kom soften cov deposits.
Siv lub siab - rab phom dej siab (30–50 MPa) nrog cov nylon txhuam kom yaug txhua ntu, tsom mus rau kev ntxuav lub khob thiab lub qhov hluav taws xob hauv qab.
Tsis txhob siv cov khoom tawv xws li xaim los txhuam, vim qhov no tuaj yeem khawb cov phab ntsa sab hauv thiab ua rau cov nplais thib ob.
2. Nruam Turbid Overflow: Txhim kho Alkali Ntxuav + Kev Tshuaj Xyuas Pem Hauv Ntej-Txoj kev tshem tawm impurity
Kev ntsuas kub ntxhov:
Ua kom cov alkali concentration mus rau 5% thiab ncua sij hawm ncig mus rau 2 teev.
Xyuas seb cov xuab zeb sib cais lossis cov tshuaj ntsuam teb tau teeb tsa ua ntej pub noj kom ntseeg tau tias cov av nkos, xuab zeb, thiab fiber ntau cuam tshuam zoo.
Yog tias qhov teeb meem tshwm sim, lub hydrocyclone tuaj yeem hnav. Siv lub ntsuas phoo los xyuas qhov kab ntawm lub qhov taub; hloov nws yog tias nws tshaj qhov txwv.
3. Cov tshuaj ntxuav cov seem muaj feem cuam tshuam rau qhov zoo: Txhim kho qhov kev yaug zaum kawg + kev tswj dej kom zoo
Txoj kev kho: Ua kom lub sij hawm yaug nrog dej huv kom ntau dua 30 feeb kom txog thaum cov kua dej pH ze rau nruab nrab thiab turbidity<5 NTU.
Siv cov dej softened los yog RO dej rau qhov kawg yaug kom tsis txhob muaj cov calcium thiab magnesium ions thiab scaling los ntawm siab - dej hardness.
4. Cov khoom xau lossis deformation: Tshawb xyuas cov ntsaws ruaj ruaj + kev tiv thaiv kub
Ua rau kev tshawb nrhiav: Puas yog cov tshuaj alkaline kub siab tshaj 80 degree? Cov kub kub tuaj yeem ua rau cov nylon cyclone raj tau yooj yim deform thiab ntsws.
Puas yog O-rings laus? Txheeb xyuas qhov kev foob tom qab txhua qhov disassembly thiab sib dhos; hloov tam sim yog tias pom muaj kab nrib pleb.
Cov lus qhia txog kev tiv thaiv: Khaws lub kaw lus kom ntub dej thaum lub sij hawm ntev - kaw lub sij hawm kom tsis txhob qhuav thiab shrinkage.
5. Hla- paug (piv txwv li, cov protein ntau dhau tom qab txiav pob kws rau hauv cov qos yaj ywm qab zib): Ua peb- theem tu
Cov txheej txheem txheej txheem: Yaug nrog dej huv rau 15 feeb kom tshem tawm cov tshuaj soluble.
Ci 2% NaOH tov ntawm 60-65℃rau 1 teev.
Tshem tawm cov khoom tseem ceeb thiab yaug qhov muag tsis pom kev zoo nrog lub siab - rab phom dej siab.
Qhov no zoo tshem tawm cov protein seem ntawm cov khoom qub, tiv thaiv kev kis kab mob los ntawm cov khoom tshiab.
III. Cov tswv yim tswv yim los txhim kho kev ua haujlwm huv
Preheat cov tshuaj alkaline rau 60-65 degree: Txhim kho cov protein decomposition efficiency thiab txo lub sij hawm tu.
Txhim kho qhov sib txawv siab sib txawv: Saib xyuas qhov sib txawv ntawm ntau theem hauv lub sijhawm; cia li ua rau lub tswb ntxuav thaum ΔP> 0.08 MPa.
Siv bio-enzyme ntxuav tus neeg sawv cev los hloov ib feem ntawm kev ntxuav cov alkaline: Ib puag ncig tus phooj ywg thiab tsis yog-corrosive, haum rau cov kab ntau lawm nrog cov khoom noj khoom haus siab, tshwj xeeb tshaj yog muaj feem xyuam rau kev ua raws li cov kev cai ntawm cov tshuaj ntxuav hauv Wuxi.
