1. Tus nqi ziab ntawm cov khoom siv kom qhuav
1. Qhov hnyav poob los ntawm cov khoom siv hauv chav tsev thiab chav tsev yog hu ua tus ntsuas kom qhuav.
2. Kom yooj yim.
● Lub sijhawm xub thawj: Lub sijhawm luv luv, txhawm rau hloov cov khoom siv rau tib yam li lub tshuab ziab khaub ncaws.
● Lub sijhawm nrawm nrawm: Qhov no yog thawj lub sijhawm nrog tus nqi ziab siab tshaj plaws. Cov dej yaj los ntawm cov npoo ntawm cov khoom tau rov qab tawm sab hauv, yog li lub npoo dej zaj duab xis tseem muaj thiab khaws cia ntawm lub teeb ntub dej.
● Ntu 1 ntawm deceleration: nyob rau lub sijhawm no, yog li cov yeeb yaj kiab dej tsis tuaj yeem ua rau tawg, thiab tus nqi ziab pib ua kom qeeb. Cov khoom yog hu ua qhov tseem ceeb ntawm qhov no, thiab cov dej muaj nyob rau lub sijhawm no yog hu ua yog qhov tseem ceeb noo noo.
● Ntu 2 ntawm deceleration: Cov theem no tsuas yog muaj rau cov ntaub ntawv tuab, vim dej tsis yooj yim los txog; Tab sis tsis yog rau cov ntaub ntawv ntxeem tau. Hauv thawj theem, txoj kev evaporation yog feem ntau nqa tawm ntawm qhov chaw. Hauv theem ob, cov zaj duab xis dej nyob rau saum npoo yog tag nrho ploj mus, yog li cov dej diffuses mus rau saum npoo hauv daim ntawv ntawm dej vapor.
2. Qhov xwm txheej cuam tshuam rau cov nqi ceev tas li
● Huab cua kub: Yog tias qhov kub muaj nce, tus nqi ntawm evaporation tus hws yuav nce ntxiv.
● Cov av noo ntawm huab cua: Thaum cov av noo yog qis dua, tus neeg evaporation ntawm cov dej yuav loj dua.
● Airflow nrawm: Tus nrawm dua ceev ceev, qhov zoo dua qhov hloov pauv loj thiab kev hloov cua sov.
● Shrinkage thiab cov ntaub ntawv tawv tawv: Ob qho xwm txheej yuav cuam tshuam rau kom qhuav.
3. Kev faib tawm ntawm cov khoom siv kom qhuav
Qhov ntau noo noo yuav tsum tau muab tshem tawm kom ntau li ntau tau ua ntej cov khoom nkag mus rau cov khoom siv.
● Lub tshuab ziab khaub ncaws rau cov khib nyiab thiab pastes.
(1) Disc lub tshuab ziab khaub ncaws.
(2) kev thauj tshuab hluav taws xob.
(3) lub tshuab ziab khaub ncaws teb.
(4) Ntsia Hlau Conveyor Dryers.
(5) Nyiaj Siv Ua Haujlwm Nruab Nrab.
(6) agitator tshuab ziab khaub ncaws.
(7) Flash Evaporation Tshuab.
(8) nruas tshuab ziab khaub ncaws.
● Kev daws teeb meem thiab slurry yog qhuav los ntawm thermal evaporation.
(1) nruas tshuab ziab khaub ncaws.
(2) tsuag dej ziab.
