Lub ntiaj tebqab zibcov txheej txheem tsim khoom, suav nrog kev ua kom cov qab zib thiab cov qab zib beet, yog ib qho kev ua haujlwm tshuaj lom neeg nyuaj uas tsom mus rau kev rho tawm thiab ntxuav cov sucrose kom zoo. Hauv plawv ntawm qhov kev ua haujlwm nyuaj no yog qhov xav tau tseem ceeb rau kev saib xyuas cov txheej txheem tiag tiag, thiab tsis muaj dab tsi tseem ceeb dua rau kev ua haujlwm zoo, zoo, thiab kev tswj tus nqi dua likev ntsuas qhov ceev hauv online.
Cov Txheej Txheem Tsim Qab Zib
LubCov txheej txheem tsim cov sucroselub hauv paus ntsiab lus yog kev sib xyaw cov kua qab zib diluted rau hauv cov slurry uas muaj cov ntsiab lus siab, ua raws li kev tswj hwm crystallization. Qhov kev hloov pauv no nyob ntawm kev tswj hwm qhov ceev ntawm ob theem tseem ceeb:
Kauj Ruam 1: Kev Ua Pa thiab Kev Sib Sau Ua Ke
Tom qab nias thiab ua kom meej thawj zaug, cov kua qab zib uas tau los ua yog cov kua uas yaj (kwv yees li 15% – 20% sucrose) nrog qhov ceev tsawg. Cov kua no yuav tsum tau concentrated hauv cov evaporators ntau yam. Thaum cov dej raug tshem tawm sai sai los ntawm kev cua sov, cov kua hloov mus ua cov kua qab zib concentrated nrog cov ntsiab lus sucrose ntau dua (60% – 70%) thiab qhov ceev.
Kev Pheej Hmoo ntawm Kev Tsis Txaus Siab:Qhov tsis txaus concentration (low density) txhais tau tias lub evaporator tsis ua haujlwm hnyav txaus. Kev xa cov cawv qis-density mus rau cov crystallizers ua rau lub sijhawm npau npau tom qab ntawd, ua rau siv cov pa ntau dhau, uas yog ib feem tseem ceeb ntawm kev tsim khoomnqi.
Kev Pheej Hmoo ntawm Kev Sib Sau Ntau Dhau (Fouling):Ntawm qhov tod tes, yog tias qhov ntom ntom dhau heev, cov slurry yuav ncav cuag ua ntej lub sijhawm.kev ua kom ntau dhauQhov no ua rau cov siv lead ua kom sai sai thiab lo rau ntawm phab ntsa ntawm lub raj xa dej, ib qho xwm txheej hu ua scaling lossis fouling. Qhov kev txhaws no yuav tsum tau siv sijhawm ntau thiab kim heev rau kev kaw lub tshuab kom huv, ua rau cov nroj tsuag poob qis heev.kev ua haujlwm tau zoo.
Kauj Ruam 2: Kev Kho Ua Ntej-crystallization thiab Kev Npau Dej
Cov slurry concentrated yog cov khoom siv pub rau cov tank crystallization, lossiscov lauj kaub nqus tsevUa ntej cov txheej txheem nyuaj ntawmkub npau(kev loj hlob ntawm cov siv lead ua) pib, qhov ceev ntawm cov cawv yuav tsum tau kho kom raug kom ua tiav qib xav tau ntawmkev ua kom ntau dhau, uas dictates qhov kawg crystal yam ntxwv.
Kev Cuam Tshuam ntawm Qhov Ceev Qis (Tsis Txaus Supersaturation):Yog tias qhov density qis dhau,cov kua qaub ntsuabyuav loj hlob qeeb qeeb, tej zaum yuav yaj rov qab mus rau hauv cov kua, lossis tsim cov noob me me thiab tsis sib xws. Qhov no thaum kawg ua rau cov khoom kawg qhov loj me faib thiab cuam tshuamkev dawb huv.
Kev Cuam Tshuam ntawm Kev Ceev Siab (Kev Nqus Ntau Dhau):Qhov ceev dhau ua rau muaj kev sib xyaw ntau dhau. Qhov no ua rau cov siv lead ua kom loj hlob sai dhau, ua rau muaj qhov tshwm sim tsis zoo ntawm kev txhaws lossiscov impurities encapsulate(zoo li cov xim pigments) uas muaj nyob rau hauv cov dej cawv niam. Cov suab thaj tiav lawm, uas yog cov suab thaj dawb huv siab, yuav hloov xim (piv txwv li, hloov mus ua xim daj lossis "suab thaj xim av"), yog li ua tsis tau raws li qhov yuav tsum tau ua.cov qauv zoo.
Qhov ceev ntawmsucrose kua txivua haujlwm ua ib qho kev ntsuas ntau, txuas ntxiv ntawm nwscov piam thaj (Brix)Vim tias Brix qhia txog saj, qauv, thiab kev huv, nws thiaj li saib xyuas qhov ceev kom meej nrog qhov tseeb siab.lub ntsuas qhov ntom ntawm qab zibyog txoj hauv kev zoo tshaj plaws los xyuas kom meej tias cov khoom zoo kawg. Kev hloov pauv me me hauv kev tswj qhov ceev tuaj yeem yooj yim txhais mus rau hauv 0.8–1.2 Brix kev hloov pauv, qhov kev hloov pauv tseem ceeb thiab tsis lees txais hauv cov khoom uas saj thiab kev huv yog qhov tseem ceeb. kev siv cov khoom tshwj xeebcov khoom siv los ntsuas qhov ceev ntawm cov kua qab zibtsis muaj kev sib tham rau kev tsim khoom niaj hnub no.
