1. Hla ntws tshuab ziab khaub ncaws
Lub tshuab ziab khaub ncaws yog thawj tus qauv qhia hauv peb lub teb chaws, feem ntau yog cylindrical lossis square-tower sieve qauv, thiab tseem muaj ntau lub tuam txhab tsim khoom hauv tsev.
Qhov zoo ntawm lub tshuab no yog: cov txheej txheem tsim khoom yooj yim, kev teeb tsa yooj yim, tus nqi qis thiab kev tsim khoom siab. Qhov tsis zoo yog: tsis zoo ib yam ntawm cov nplej kom qhuav, kev siv hluav taws xob siab, kev ua kom qhuav ntawm ntau hom nplej hauv ib lub tshuab, nyuaj ua kom tau raws li qhov yuav tsum tau ua ntawm qee cov nplej tom qab ziab, thiab nquag ntxuav ntawm sab hauv thiab sab nrauv sieve qhov. Txawm li cas los xij, lub tshuab ziab khaub ncaws me me tuaj yeem zam qee qhov kev tsis txaus siab saum toj no.
2. Mixed flow dryer
Mixed-flow tshuab ziab khaub ncaws feem ntau yog cov qauv ntauwd tsim los ntawm cov duab peb sab lossis pentagonal thawv staggered (forked). Muaj ntau cov tuam txhab tsim khoom hauv tsev ntawm cov qauv no ntau dua li kev sib tw. Piv nrog rau kev khiav dej num, nws qhov zoo yog: (1) Cov khoom cua kub yog txawm tias, thiab cov ntsiab lus noo noo ntawm cov nplej tom qab ziab yog ntau yam sib xws; (2) Chav tsev siv hluav taws xob qis qis los ntawm 5% mus rau 15%; 3) Lub zog kiv cua xav tau nyob rau hauv tib yam kev mob me me, thiab chav siv ntawm ziab nruab nrab kuj yog me me; (4) Muaj ntau hom nplej qhuav, uas tuaj yeem qhuav nplej thiab noob; (5) Nws yooj yim los ntxuav thiab tsis yooj yim rau kev sib xyaw.
Qhov tsis zoo yog: (1) Cov qauv yog complex, thiab cov nqi tsim khoom yog me ntsis siab dua nyob rau hauv tib yam khoom; (2) Cov nag lossis daus ntawm ib feem me me ntawm cov nplej ntawm plaub fab ntawm lub tshuab ziab khaub ncaws qeeb.
3. Downstream tshuab ziab khaub ncaws
Downstream tshuab ziab khaub ncaws feem ntau yog cov qauv ntauwd uas sib txuas cov funnel-hom cua inlets thiab angular box tso ducts. Nws yog qhov sib txawv ntawm cov tshuab ziab khaub ncaws sib xyaw uas siv ib lub tshuab cua loj los muab cov cua kub, tab sis nws muaj ntau yam (theem). Cov yeeb nkab cua kub muab cov khoom sib txawv los yog ib feem ntawm cov cua kub tib yam.
Tus naj npawb ntawm cov tuam txhab tsim khoom hauv tsev yog tsawg dua li ntawm cov tshuab ziab khaub ncaws sib xyaw. Nws qhov zoo yog: (1) Cov cua kub kub yog siab, thiab qhov kub thiab txias nyob rau hauv thawj theem siab kub tuaj yeem ncav cuag 150-250 degree; (2) Chav tsev siv hluav taws xob tsawg, uas tuaj yeem lav cov qoob loo qhuav Zoo; (3) Cov tshuab ziab khaub ncaws nrog peb theem qis qis thiab saum toj no muaj qhov zoo ntawm kev txo cov dej loj thiab tuaj yeem tau txais kev tsim khoom ntau dua; (4) Muaj nag lossis daus loj thaum lub sij hawm qhuav tas mus li, feem ntau txog li 10% txog 15%; (5) Feem ntau haum rau ziab cov qoob loo thiab cov noob uas muaj cov dej noo siab.
Qhov tsis zoo yog: (1) Cov qauv yog qhov nyuaj, thiab cov nqi tsim khoom yog nyob ze lossis siab dua me ntsis ntawm cov tshuab ziab khaub ncaws sib xyaw; (2) Lub thickness ntawm grain txheej yog loj, yuav tsum tau high-pressure kiv cua zog yog loj, thiab tus nqi yog siab.
4. Tshuab ziab khaub ncaws rau pem hauv ntej thiab countercurrent, mix countercurrent thiab forward mix flow
Ntshiab countercurrent tshuab ziab khaub ncaws tsis tshua tsim thiab siv. Lawv feem ntau yog siv ua ke nrog cov tshuab ziab khaub ncaws nrog lwm cov cua ntws, uas yog, siv nyob rau hauv qhov chaw txias ntawm cov khoom siv tam sim no lossis cov tshuab ziab khaub ncaws sib xyaw ua ke los tsim cov tshuab ziab khaub ncaws tam sim no thiab sib xyaw ua ke. Qhov kom zoo dua ntawm kev ua kom txias txias yog qhov cua txias huab cua tuaj yeem tiv tauj tag nrho cov nplej, uas tuaj yeem ua rau kom txias ceev thiab tsim nyog txo qhov siab ntawm qhov cua txias. Lub pem hauv ntej thiab countercurrent, mix countercurrent thiab forward mix flow dryers siv lawv cov txiaj ntsig kom ua tiav qhov kub thiab txias sai, txhim kho kom qhuav muaj peev xwm, tsis muaj kev siv cua sov ntxiv, thiab ua kom cov khoom zoo thiab cov ntsiab lus noo noo.
