Spray Drying granulator tshuab ua rau siv cov tshuaj tsuag thiab kua txaj tshuab kom paub sib tov, granulation thiab ziab hauv ib lub thawv. Cov hmoov fluidized yog wetted los ntawm spaying lub extract kom txog thaum agglomeration tshwm sim. Sai li qhov loj ntawm granule mus txog. Kev txau yog nres thiab cov granules ntub dej qhuav thiab txias.
Cov hmoov granule nyob rau hauv lub nkoj (kua txaj) tshwm nyob rau hauv lub xeev ntawm fluidization. Nws yog preheated thiab tov nrog huv si thiab rhuab cua. Nyob rau tib lub sijhawm, kev daws ntawm cov nplaum yog txau rau hauv lub thawv. Nws ua rau cov khoom ua granulating uas muaj cov nplaum. Thaum tsis qhuav qhuav los ntawm huab cua kub, noo noo nyob rau hauv granulating yog evaporated. Cov txheej txheem yog nqa tawm tsis tu ncua. Thaum kawg nws tsim zoo tagnrho, niaj hnub thiab porous granules.
Txau agglomeration txav me me heev, hmoov hais nyob rau hauv lub txaj fluidized qhov twg lawv tau txau nrog ib tug binder tov los yog ncua kev kawm ntawv. Cov kav dej ua kua yog tsim uas tsim cov agglomerate los ntawm cov khoom. Txau mus txuas ntxiv kom txog thaum qhov xav tau loj ntawm cov agglomerates mus txog.
Tom qab cov residual noo noo nyob rau hauv lub capillaries thiab nyob rau saum npoo tau evaporated, hollow qhov chaw yog tsim nyob rau hauv lub granulate thaum lub tshiab qauv yog solidified thoob plaws hauv lub hardened binder. Qhov tsis muaj zog kinetic nyob rau hauv lub txaj fluidized ua rau cov txheej txheem ntxeem tau nrog ntau cov hlab ntsha sab hauv. Qhov loj npaum li cas ntawm cov agglomerate yog los ntawm 100 micrometers mus rau 3 millimeters, thaum cov khoom pib tuaj yeem yog micro-zoo.
1. Sib xyaw tshuaj tsuag, ziab cov kua granulating hauv ib lub cev kom paub txog granulating los ntawm cov kua hauv ib kauj ruam.
2. Siv cov txheej txheem ntawm kev txau, nws yog tshwj xeeb tshaj yog haum rau micro auxiliary raw cov ntaub ntawv thiab cov ntaub ntawv kub rhiab heev. Nws qhov ua tau zoo yog 1-2 npaug tshaj li ib qho ntawm cov kua dej granulator.
3. Qhov kawg ya raws ntawm qee cov khoom tuaj yeem ncav cuag 0.1%. Nws yog txawm peem rau nrog hmoov rov qab ntaus ntawv. Tus nqi ntawm granule forming yog ntau tshaj 85% nrog 0.2-2mm ntawm txoj kab uas hla.
4. Kev txhim kho sab hauv cov menyuam ntau lub tshuab nqus dej tuaj yeem kho cov kua extract nrog 1.3g / cm3 ntawm lub ntiajteb txawj nqus.
5. Tam sim no, PGL-150B, nws tuaj yeem ua 150kg / batch ntawm cov khoom.
