Raws li kev ua haujlwm siab, lub tshuab ziab khaub ncaws tau muab faib ua ob hom: cov pa taws ua kom lub tshuab cua thiab lub tshuab nqus tsev. Lub sijhawm ua haujlwm hauv lub tshuab nqus tsev tuaj yeem txo qhov noo ntawm ib nrab ntawm qhov chaw thiab ua kom cov txheej txheem kom qhuav, thiab tuaj yeem txo qhov kub npau npau ntawm cov dej ntub thiab qhov kub kom qhuav ntawm cov khoom. Kev nqus dej, yog li ntawd, lub tshuab nqus tsev yog qhov tsim nyog rau kev ziab tshav kub, oxidizable, cov khoom tawg thiab lom thiab cov chav dej ntub yuav tsum tau rov ua dua tshiab.
Raws li cov txheej txheem cua sov, lub tshuab ziab khaub ncaws tau muab faib ua hom kev sib tw, hom kev sib cais, hom hluav taws xob, hom dielectric thiab lwm yam. Convection tshuab ziab khaub ncaws, tseem hu ua cov tshuab ziab khaub ncaws ncaj qha, siv qhov chaw kub kom qhuav mus ua kom sib chwv nrog cov ntaub ntub dej hloov cov khoom kub tso rau hauv kev ua kom zoo thiab nqa khoom tawm ntawm cov khoom tsim hluav taws xob. Conductive dryers, tseem hu ua indirect dryers, siv ua conduction. Cov cua sov tau hloov los ntawm cov khoom siv kub mus rau cov khoom siv ntub dej dhau los ntawm cov hlau faib phab ntsa, thiab lub tshuab tso zis ntub dej tawm tau muab tshem tawm los ntawm lub nqus nqus, muaj cov pa roj me me lossis cov hws tawm ntawm qhov chaw ntawm cov khoom pov tseg uas tsis tshua muaj qhov kub tsis txaus. Hom tshuab ziab khaub ncaws no tsis siv cov khoom nruab nrab kom qhuav, muaj cov cua sov ua kom zoo, thiab cov khoom tsis ua paug, tab sis lub peev xwm ziab yog txwv los ntawm lub tshav kub hloov ntawm thaj chaw ntawm phab ntsa hlau, cov qauv kuj tsis yooj yim, thiab nws feem ntau ua haujlwm hauv qab. nqus tsev; lub tshuab nqus hluav taws xob siv ntau yam tawg. Cov hluav taws xob hluav taws xob tso tawm los ntawm qee yam nthwv dej ntom nti tau xaiv los ntawm qhov chaw ntawm cov khoom ntub thiab tom qab ntawd hloov mus ua cua sov kom qhuav; lub tshuab ziab hluav taws xob siv hluav taws xob siv ntau qhov chaw siv hluav taws xob ua rau lub zog cua sov hauv cov khoom ntub kom qhuav.
