Hlau hluav taws xob yog cov cuab yeej rau qib khaub ncaws thiab ntaub, thiab nws lub zog feem ntau ntawm 300-1000W. Nws hom tuaj yeem muab faib ua: yam zoo tib yam, hom kev hloov pauv kub, hom tshuaj tsuag thiab lwm yam. Cov hluav taws xob hluav taws xob yooj yim yog cov qauv yooj yim, tus nqi qis, thiab yooj yim rau kev tsim khoom thiab tswj hwm.
Kev ntsuas hluav taws xob ntsuas hluav taws xob tuaj yeem hloov kho qhov kub nyob hauv thaj tsam ntawm 60-250 ℃, thiab tuaj yeem txiav tawm lub zog. Nws tuaj yeem ua kom sov ntawm qhov ntsuas kub haum raws li cov khoom siv khaub ncaws sib txawv, uas yog txuag hluav taws xob ntau dua li hom ib txwm. Cov tshuaj tsuag hom hluav taws xob tsis tsuas yog muaj qhov ua haujlwm ntawm kev hloov pauv kub, tab sis kuj tsim cov pa. Qee qhov kuj tau nruab nrog lub tshuab txau kom tsis txhob muaj teeb meem ntawm phau ntawv txau dej, thiab cov khaub ncaws ntau dua sib npaug thiab ua kom cov hlau zoo dua.
Ib qho khoom siv tu tsev uas siv hluav taws xob cua sov los txhuam cov khaub ncaws. Nws yog ib qho khoom siv hluav taws xob tseem ceeb hauv tsev neeg niaj hnub no. Nws yog cov cuab yeej rau qib khaub ncaws thiab ntaub. Lub zog feem ntau ntawm 300-1000W. Nws cov hom tuaj yeem faib ua: yam zoo tib yam, hom ntsuas kub, ntsuas chav, hom tshuaj tsuag kom zoo thiab lwm yam hluav taws xob tau ua los ntawm kev siv cov cua sov ua hluav taws xob tam sim no thiab siv los ua khaub ncaws. Xyoo 1882, Asmeskas HW Sealy tau txais thawj daim ntawv pov thawj hluav taws xob hlau. Thaum pib ntawm lub xyoo pua 20th, lub tshuab hluav taws xob tau tsim los ntawm E. Richardson ntawm Tebchaws Meskas tau muab tso rau hauv khw thiab tau txais tos. Cov hluav taws xob hluav taws xob tau yooj yim hauv cov qauv, tsim khoom yooj yim, thiab siv tau yooj yim, yog li lawv tau tsim kho sai. Muaj ob hom hluav taws xob hluav taws xob uas tau tsim thiab siv ntau zaus hauv peb lub tebchaws, yam zoo li qub thiab qhov ntsuas kub zoo tib yam. Cov hom hluav taws xob tshiab, xws li hom dav hlau, hom tshuaj tsuag, hom ntsuas kub thiab qhov ntsuas hluav taws xob, kuj tau tshwm sim. Lub zog loj, lub cev nyhav, kev ntsuas kub tsis siv neeg, ua pa lossis tshuaj tsuag, thiab ua kom pom qhov zoo nkauj yog kev txhim kho kev coj ua ntawm cov hluav taws xob tshiab tiam tshiab.
