Cov khoom siv granular, xws li chiv, khoom noj khoom haus additives, thiab kws tshuaj, yog ib qho tseem ceeb ntawm ntau lub lag luam. Cov khoom no yog tus cwj pwm los ntawm lawv qhov me me, qhov loj me thiab yooj yim ntawm kev tuav, uas ua rau lawv zoo tagnrho rau kev thauj mus los thiab khaws cia. Cov txheej txheem tsim khoom ntawm cov khoom granular suav nrog ob peb kauj ruam, txhua qhov tseem ceeb rau qhov kawg ntawm cov khoom zoo thiab kev ua haujlwm.
Kauj Ruam 1: Xaiv cov khoom nyoos
Thawj kauj ruam hauv kev tsim cov khoom siv granular yog xaiv cov khoom siv raw. Qhov zoo ntawm cov khoom siv raw siv ncaj qha cuam tshuam rau qhov zoo ntawm cov khoom kawg. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv cov khoom siv raw uas ua tau raws li cov qauv thiab cov kev qhia tshwj xeeb.
Piv txwv li, hauv kev tsim cov chiv, cov khoom siv raw yuav tsum muaj cov ntsiab lus zoo thiab tsis muaj cov kab mob xws li cov hlau hnyav. Piv txwv li, nyob rau hauv kev tsim cov khoom noj khoom haus additives, cov ntaub ntawv raw yuav tsum yog cov zaub mov-qib thiab ua tau raws li cov kev cai.
Kauj Ruam 2: Sib tov thiab sib tov
Tom qab xaiv cov khoom siv raw, cov kauj ruam tom ntej yog sib tsoo thiab sib tov. Cov kauj ruam no yuav txo tau cov khoom raw 'particle loj thiab sib tov lawv uniformly. Cov txheej txheem sib tsoo yuav pab kom tawg ib qho lit cia cov lumps lossis agglomerates hauv cov ntaub ntawv raw, ua kom yooj yim rau lis thiab ua kom muaj kev sib txawv hauv cov khoom kawg.
Cov txheej txheem sib xyaw yog qhov tseem ceeb hauv kev ua kom ntseeg tau tias cov khoom kawg muaj qhov sib xws. Nyob rau hauv cov ntaub ntawv ntawm cov chiv ntau lawm, cov txheej txheem sib tov ua kom ntseeg tau tias txhua granule muaj cov ntsiab lus zoo. Ib yam li ntawd, hauv kev tsim cov khoom noj khoom haus ntxiv, cov txheej txheem sib xyaw ua kom ntseeg tau tias txhua granule muaj qhov tseeb tsw lossis xim.
Kauj Ruam 3: Granulation
Cov txheej txheem granulation suav nrog kev tsim cov khoom sib xyaw ua ke rau hauv granules ntawm ib qho loj me thiab cov duab. Granulation tuaj yeem ua tiav los ntawm ntau txoj hauv kev, suav nrog extrusion, compaction, thiab txau kom qhuav.
Extrusion suav nrog yuam cov khoom sib xyaw ua ke los ntawm kev tuag los tsim cov kwj ntawm cov granules tsis tu ncua. Compaction suav nrog nias cov khoom sib xyaw ua ke rau hauv ib lub ncuav mog qab zib, uas tom qab ntawd tawg mus rau hauv granules ntawm ib qho loj me. Txau kom qhuav muaj atomizing ib qho kev daws ntawm cov khoom sib xyaw ua ke thiab ziab cov tee dej los ua granules.
Kev xaiv ntawm granulation txoj kev nyob ntawm ntau yam, nrog rau cov khoom siv raw, cov yam ntxwv ntawm cov khoom xav tau, thiab cov nplais ntau lawm.
Kauj Ruam 4: Qhuav thiab txias
Tom qab granulation, cov granules tau qhuav kom tshem tawm cov dej noo ntxiv. Kev ziab yog qhov tseem ceeb hauv kev ua kom ntseeg tau tias cov granules ruaj khov thiab tsis clump lossis lo ua ke thaum khaws cia thiab thauj. Kev ziab yog feem ntau ua tiav los ntawm huab cua kub lossis fluidized txaj kom qhuav.
Tom qab ziab, cov granules yog txias rau chav tsev kub. Kev txias txias pab txo qhov kev pheej hmoo ntawm cov khoom degradation thiab xyuas kom meej tias cov granules muaj kev nyab xeeb los tuav thiab pob.
Kauj Ruam 5: Kev tshuaj ntsuam thiab ntim
Cov kauj ruam kawg hauv kev tsim cov khoom siv granular yog kev tshuaj xyuas thiab ntim khoom. Cov txheej txheem tshuaj ntsuam xyuas yuav tshem tawm cov granules loj los yog undersized uas yuav cuam tshuam rau cov khoom lag luam kev ua tau zoo lossis cov tsos.
Cov txheej txheem ntim khoom suav nrog ntim cov granules rau hauv hnab lossis ntim khoom tsim nyog rau kev khaws cia thiab kev thauj mus los. Cov khoom ntim yuav tsum ua kom ntev thiab tiv thaiv cov granules los ntawm noo noo, oxygen, thiab lwm yam ib puag ncig uas yuav cuam tshuam rau cov khoom zoo.
Kev Tswj Xyuas Zoo
Thoob plaws hauv cov txheej txheem tsim khoom, kev tswj kom zoo yog qhov tseem ceeb los xyuas kom meej tias cov khoom kawg ua tau raws li qhov xav tau tshwj xeeb thiab cov qauv. Kev tswj xyuas zoo suav nrog kev saib xyuas thiab ntsuas cov khoom siv raw, cov khoom nruab nrab, thiab cov khoom kawg kom ntseeg tau tias lawv ua tau raws li cov qauv tsim nyog.
Ntau yam kev ntsuam xyuas tau ua, suav nrog kev tshuaj xyuas tshuaj, tshuaj xyuas lub cev, thiab tshuaj xyuas microbial, kom ntseeg tau tias cov khoom muaj kev nyab xeeb, siv tau zoo, thiab ua tau raws li qhov xav tau tshwj xeeb.
Xaus
Hauv kev xaus, cov txheej txheem tsim khoom ntawm cov khoom granular suav nrog ntau cov kauj ruam tseem ceeb uas yog qhov tseem ceeb hauv kev ua kom ntseeg tau tias cov khoom kawg yog cov khoom zoo thiab ua tau raws li cov qauv thiab cov kev qhia tshwj xeeb.
