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(dao)(dao)的種類很多，我(wo)所(suo)知(zhi)道(dao)(dao)的有(you)熱風循環烘(hong)(hong)(hong)(hong)道(dao)(dao)，紅(hong)外(wai)熱風高溫(wen)烘(hong)(hong)(hong)(hong)道(dao)(dao)，紅(hong)外(wai)線烘(hong)(hong)(hong)(hong)道(dao)(dao)，熱風循環烘(hong)(hong)(hong)(hong)道(dao)(dao)等等。不同(tong)烘(hong)(hong)(hong)(hong)道(dao)(dao)有(you)不同(tong)的工藝，實(shi)現不同(tong)的適用范(fan)圍(wei)和作用。

例如紅外線烘(hong)道(dao)廣泛(fan)應用于(yu)絲網印刷(shua)、噴(pen)染、電鍍(du)以及印刷(shua)電路(lu)等行業的烘(hong)干、除濕等工藝，還可用于(yu)食品(pin)、紡織品(pin)、壓鑄小件等工業的干燥(zao)、烘(hong)烤等。

工作原理：電(dian)加(jia)熱(re)平板(ban)線(xian)烘道采(cai)用加(jia)熱(re)管外置式(shi)加(jia)熱(re)，將電(dian)能(neng)轉化為熱(re)能(neng)，熱(re)量經低(di)噪音高壓風(feng)機(ji)吹(chui)入(ru)進風(feng)道，傳入(ru)箱內，形成熱(re)風(feng)循環， 箱體設有(you)對流攪拌技術，溫(wen)度非常均勻，具(ju)有(you)自(zi)動(dong)控溫(wen)，調速，故障報(bao)警等(deng)特點(dian)(dian)，使用安全(quan)，方便，環保(bao)，節(jie)能(neng)等(deng)優點(dian)(dian)。

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

網帶為優(you)質鐵氟龍耐高溫網帶，另有(you)控(kong)(kong)制(zhi)器，調速器，低壓電(dian)器控(kong)(kong)制(zhi)系統等控(kong)(kong)制(zhi)系統部分。
