烘道機工作場所整潔，生產效率高，是目前我國制藥廠、中藥廠、飲料廠、日用化工廠必不可少的設備之一。

烘(hong)(hong)(hong)(hong)道的(de)(de)種類很多，我(wo)所(suo)知道的(de)(de)有熱(re)(re)風循環烘(hong)(hong)(hong)(hong)道，紅(hong)外熱(re)(re)風高(gao)溫(wen)烘(hong)(hong)(hong)(hong)道，紅(hong)外線烘(hong)(hong)(hong)(hong)道，熱(re)(re)風循環烘(hong)(hong)(hong)(hong)道等(deng)等(deng)。不(bu)同(tong)(tong)烘(hong)(hong)(hong)(hong)道有不(bu)同(tong)(tong)的(de)(de)工(gong)藝，實(shi)現(xian)不(bu)同(tong)(tong)的(de)(de)適(shi)用范圍和作用。

例如(ru)紅(hong)外(wai)線烘(hong)道(dao)廣泛應用于(yu)(yu)絲(si)網(wang)印刷(shua)、噴(pen)染、電鍍以(yi)及印刷(shua)電路(lu)等(deng)(deng)行業的烘(hong)干、除濕等(deng)(deng)工(gong)藝(yi)，還可(ke)用于(yu)(yu)食品、紡織品、壓鑄小(xiao)件等(deng)(deng)工(gong)業的干燥、烘(hong)烤等(deng)(deng)。

工作原理：電加(jia)熱(re)平板線(xian)烘道(dao)采用加(jia)熱(re)管(guan)外置(zhi)式加(jia)熱(re)，將電能(neng)(neng)轉(zhuan)化(hua)為熱(re)能(neng)(neng)，熱(re)量(liang)經低噪(zao)音高壓風機吹入(ru)進風道(dao)，傳入(ru)箱內，形成熱(re)風循環(huan)， 箱體設有(you)對流攪拌技(ji)術(shu)，溫(wen)度非常均勻，具有(you)自(zi)動控(kong)溫(wen)，調速(su)，故障報警等特點，使用安全，方(fang)便，環(huan)保，節能(neng)(neng)等優點。

材料：烘道內采用優質鍍鋅板，外壁采用優質成型彩鋼板制作，大梁用后成型鋼板制作，保溫層采用纖維石棉保溫電加熱管為耐高溫不銹鋼無縫鋼管，結晶氧化鎂粉做絕緣，風機采用低噪聲高壓離心風機，保溫采用硅酸鋁纖維棉

網帶(dai)為優質鐵氟龍耐(nai)高溫網帶(dai)，另(ling)有控(kong)(kong)制器(qi)，調(diao)速器(qi)，低壓電器(qi)控(kong)(kong)制系統(tong)(tong)等控(kong)(kong)制系統(tong)(tong)部(bu)分。
