Taw qhia
Kev ntub dej granulation yog cov txheej txheem ntau siv hauv kev lag luam tshuaj, tshuaj, thiab zaub mov los npaj cov granules ntawm qhov xav tau loj thiab cov duab rau kev ua haujlwm ntxiv lossis ntim khoom. Kev ntub dej granulation yog ua tiav los ntawm kev ntxiv cov kua nplaum rau cov hmoov sib tov zoo thiab sib xyaw ua ke rau hauv granules los ntawm kev siv cov ntub dej granulator.
Cov granulator ntub dej tuaj yeem muaj ntau yam duab thiab qhov ntau thiab tsawg, thiab xaiv qhov tsim nyog rau ib qho txheej txheem tshwj xeeb yog nyob ntawm ntau yam, suav nrog qhov xwm txheej ntawm cov hmoov granulated, qhov xav tau qhov loj me thiab cov duab ntawm cov granules, thiab ntau lawm. tus nqi yuav tsum tau. Kab lus no yuav piav qhia seb lub granulator ntub dej yog dab tsi, nws ua haujlwm li cas, thiab nws qhov zoo thiab qhov tsis zoo.
Dab tsi yog Wet Granulator?
Lub granulator ntub dej yog lub tshuab siv los tig cov hmoov sib tov rau hauv granules. Lub tshuab ua haujlwm los ntawm kev rhuav tshem cov hmoov nplej thiab agglomerating lawv mus rau hauv granules los ntawm kev siv cov kua binder. Cov kua nplaum tuaj yeem yog aqueous lossis tsis yog aqueous, nyob ntawm qhov xwm ntawm cov hmoov sib xyaw ua granulated.
Cov granulators ntub dej feem ntau muaj cov rotor nrog ntau cov hniav, uas tig ntawm qhov nrawm los tsim lub zog shearing uas ua rau cov hmoov av tawg. Cov kua nplaum yog ntxiv rau cov hmoov sib tov los ntawm cov tshuaj tsuag nozzle, thiab cov sib tov yog ces agglomerated rau hauv granules los ntawm qhov kev txiav txim ntawm cov hniav.
Qhov loj ntawm cov granules uas tsim los ntawm cov granulator ntub dej tuaj yeem tswj tau los ntawm kev kho qhov ceev ntawm cov hniav, tus nqi ntawm cov kua binder ntxiv, thiab qhov loj ntawm lub qhov ntawm qhov screen los ntawm cov granules tawm. Cov granulator ntub dej tuaj yeem tsim cov granules hauv ntau hom duab, suav nrog spheres, cylinders, thiab cubes.
Cov granulators ntub dej tuaj yeem siv rau ntau hom hmoov sib tov, nrog rau cov tshuaj, tshuaj, thiab khoom noj khoom haus. Lawv muaj txiaj ntsig tshwj xeeb rau cov hmoov uas nyuaj rau compress rau hauv cov ntsiav tshuaj lossis tshuaj ntsiav, vim tias cov granulation ntub dej tuaj yeem txhim kho cov flowability thiab compressibility ntawm cov hmoov, ua kom yooj yim rau hauv cov ntaub ntawv ntau npaum li cas.
Yuav Ua Li Cas Cov Dej Granulator Ua Haujlwm?
Kev ntub dej granulation yog txheej txheem nyuaj uas suav nrog ntau cov kauj ruam. Thawj kauj ruam yog npaj cov hmoov sib tov kom granulated. Qhov no feem ntau yog muab cov hmoov sib tov sib xyaw ua ke los tsim kom muaj qhov sib xyaw ua ke. Cov hmoov sib tov kuj tseem tuaj yeem ua ntej milled kom ntseeg tau tias tag nrho cov khoom muaj qhov sib xws.
Thaum cov hmoov sib tov yog npaj txhij, lub ntub granulator yog teem. Lub tshuab feem ntau yog nruab nrog lub hopper rau pub cov hmoov sib tov rau hauv lub tshuab, tshuaj tsuag nozzle rau ntxiv cov kua binder, thiab lub rotor tig nrog cov hniav rau agglomerating cov sib tov rau hauv granules.
Cov kua nplaum yog ntxiv rau cov hmoov sib tov los ntawm cov tshuaj tsuag nozzle, uas feem ntau nyob saum lub rotor. Cov kua nplaum yog xa mus rau hauv kev tswj hwm, feem ntau los ntawm lub twj tso kua mis peristaltic, kom ntseeg tau tias cov ntaub ntawv sib npaug sib npaug thoob plaws hauv cov hmoov sib tov.
Raws li lub rotor rotates, cov hniav tsim ib tug shearing quab yuam uas lov li cov hmoov hais thiab agglomerate lawv mus rau hauv granules. Qhov loj thiab cov duab ntawm cov granules tuaj yeem tswj tau los ntawm kev kho qhov ceev ntawm cov hniav, tus nqi ntawm cov kua binder ntxiv, thiab qhov loj ntawm lub qhov ntawm qhov screen los ntawm cov granules raug tso tawm.
Thaum cov granules raug tsim, lawv feem ntau qhuav kom tshem tawm cov seem seem thiab ces sieved kom tshem tawm tej qhov loj los yog undersized hais. Tom qab ntawd cov granules tuaj yeem ua tiav rau hauv cov ntsiav tshuaj lossis tshuaj ntsiav, lossis lawv tuaj yeem muab ntim ua cov khoom kawg.
Qhov zoo ntawm ntub Granulation
ntub granulation muaj ib tug xov tooj ntawm zoo dua lwm yam granulation txoj kev, nrog rau qhuav granulation. Qee qhov zoo ntawm ntub granulation muaj xws li:
Txhim kho flowability: ntub dej granulation tuaj yeem txhim kho cov dej ntws ntawm cov hmoov, ua rau lawv yooj yim dua los ua cov ntaub ntawv ntau npaum li cov ntsiav tshuaj lossis tshuaj ntsiav.
Txhim kho compressibility: ntub granulation tuaj yeem txhim kho compressibility ntawm cov hmoov, ua kom yooj yim rau hauv cov ntaub ntawv ntau npaum li cas nrog cov hardness zoo ib yam thiab cov khoom tawg.
Txhim kho kev ruaj ntseg: ntub dej granulation tuaj yeem txhim kho kev ruaj ntseg ntawm cov hmoov los ntawm kev txo lawv qhov chaw saum npoo thiab raug rau huab cua thiab noo noo.
Tswj particle loj thiab cov duab: ntub granulation tso cai rau kev tswj xyuas qhov loj thiab cov duab ntawm cov granules tsim, uas tuaj yeem yog qhov tseem ceeb rau kev ua tiav qhov kev xav tau ntawm cov khoom kawg.
Disadvantages ntawm ntub Granulation
Txawm tias nws qhov zoo, ntub granulation kuj muaj qee qhov tsis zoo piv rau lwm txoj kev granulation. Qee qhov tsis zoo ntawm ntub granulation muaj xws li:
Lub sijhawm ua haujlwm ntau ntxiv: ntub granulation tuaj yeem siv sijhawm ntev, vim tias cov granules yuav tsum tau qhuav thiab sieved tom qab lawv tsim.
Tus nqi nce ntxiv: Kev siv cov kua binders hauv ntub granulation tuaj yeem nce tus nqi ntawm cov txheej txheem piv rau qhuav granulation.
Kev pheej hmoo ntawm kev kis kab mob ntau ntxiv: Cov granulation ntub dej yuav tsum tau siv cov kua binders, uas tuaj yeem ua rau muaj kev pheej hmoo ntawm cov kab mob microbial yog tias tsis tswj kom raug.

Txawm li cas los xij, cov granulation ntub dej kuj muaj qee qhov tsis zoo, suav nrog kev siv sijhawm ntau ntxiv, tus nqi, thiab kev pheej hmoo ntawm kev kis kab mob. Thaum txiav txim siab seb puas yuav siv cov granulation ntub dej, nws yog ib qho tseem ceeb kom ua tib zoo xav txog cov kev xav tau tshwj xeeb ntawm cov txheej txheem thiab ntsuas qhov zoo thiab qhov tsis zoo.
