Kom qhuav khoom kom qhuav tus nqi cuam tshuam cov yam ntxwv thiab kev ua kom qhuav

Abstract:

I. Drying khoom kom qhuav tus nqi 1. Cov khoom siv kom qhuav ib ce 1. Chav nyob ntawm cov khoom poob, hu ua tus ntsuas kom qhuav. 2. Cov txheej txheem kom qhuav (1) Lub sijhawm thawj zaug: lub sijhawm luv luv, rau kev hloov kho ntawm cov khoom siv tib yam li lub tshuab ziab khaub ncaws. (2) Lub sijhawm nrawm Cov.

I. Kom huv cov khoom kom qhuav tus nqi

1. Chav sijhawm thiab chav tsev, qhov hnyav ntawm cov khoom ploj, paub tias yog tus nqi ziab.

2. Cov txheej txheem kom qhuav

(1) Lub sijhawm pib: Lub sijhawm luv, rau cov khoom siv yuav raug hloov kho kom zoo ib yam li lub tshuab ziab khaub ncaws.

(2) Lub sijhawm nrawm

(3) deceleration ntawm ib lub sijhawm: Lub sijhawm Evaporation lub sijhawm no tsis tuaj yeem rov ua yeeb yaj kiab, yog li cov dej ua kom qhuav, yog li cov khoom siv kom qeeb, cov ntaub ntawv ntawm qhov no yog Hu ua tus taw tes tseem ceeb, cov dej muaj nyob rau lub sijhawm no, hu ua qhov dej tseem ceeb.

(4) deceleration ntawm theem ob: tsuas yog cov ntaub ntawv tsuav hauv cov theem no, vim tias cov dej tsis yooj yim los txog; Tab sis cov khoom siv ntxeem tau tsis yog. Lub evaporation dej nyob rau hauv thawj lub sij hawm tau feem ntau nqa tawm ntawm sab, thiab cov zaj duab xis nyob rau hauv lub sij hawm yog kiag li ploj mus rau saum npoo nyob rau hauv daim ntawv ntawm dej vapor.

Ii. Yam cuam tshuam rau tus nqi ntawm tas mus li cas kom qhuav

1. Qhov kub ntawm huab cua: yog nce qhov kub, tus nqi cuam tshuam ntawm cov hws dej evaporation tau nce. 2. Cov av noo ntawm huab cua: ntawm cov av noo qis, cov dej evaporation tus nqi ua kom loj dua.

2. Vaum ntawm huab cua: ntawm cov av noo qis, tus neeg evaporation ntawm cov dej yuav loj dua. 3.

3. Kev tshaj tawm ntawm huab cua txaus: lub nrawm dua, qhov zoo dua ntawm cov nyhuv ntawm huab hwm coj thiab kev hloov cua sov.

4. Shrinkage thiab nto hardening: ob qho xwm txheej no yuav cuam tshuam rau kom qhuav.

III. Kev faib tawm cov khoom siv kom qhuav

Cov ntaub ntawv yuav tsum tau muab tshem tawm kom ntau li ntau tau los ntawm cov dej tshaj dhau los ua ntej nkag mus rau cov khoom siv.

1. Ziab khaub ncaws rau cov khib nyiab thiab pastes

(1) Disc Tshuab Ziab Khaub Ncaws

(2) kev thauj mus los tshuab ziab khaub ncaws

(3) Lub Tshuab Ntxhua Khaub Ncaws

(4) Ntsia Hlau Conveyor Dryers

(5) caij tshuab ziab khaub ncaws

(6) stirring tshuab ziab khaub ncaws

(7) Kev Siv Hluav Taws Xob Hluav Taws Xob

(8) lub tog raj kheej tshuab ziab khaub ncaws

2. Kom qhuav ntawm kev daws thiab slurry dej los ntawm thermal evaporation

(1) nruas tshuab ziab khaub ncaws

(2) tsuag tshuab ziab khaub ncaws
