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，我所知道(dao)(dao)的有(you)熱風(feng)(feng)循環烘(hong)(hong)(hong)(hong)道(dao)(dao)，紅(hong)外(wai)熱風(feng)(feng)高溫烘(hong)(hong)(hong)(hong)道(dao)(dao)，紅(hong)外(wai)線烘(hong)(hong)(hong)(hong)道(dao)(dao)，熱風(feng)(feng)循環烘(hong)(hong)(hong)(hong)道(dao)(dao)等(deng)等(deng)。不同烘(hong)(hong)(hong)(hong)道(dao)(dao)有(you)不同的工藝，實現不同的適用范圍和作用。

例如紅外線烘道廣泛應用(yong)于(yu)絲網印刷、噴(pen)染(ran)、電(dian)鍍以及(ji)印刷電(dian)路等(deng)行(xing)業的烘干、除(chu)濕等(deng)工(gong)藝，還可(ke)用(yong)于(yu)食品、紡(fang)織品、壓鑄小件等(deng)工(gong)業的干燥、烘烤等(deng)。

工作原理：電(dian)加(jia)熱平(ping)板線烘道(dao)采用(yong)加(jia)熱管外置式(shi)加(jia)熱，將電(dian)能(neng)轉(zhuan)化為(wei)熱能(neng)，熱量(liang)經(jing)低噪(zao)音(yin)高壓風(feng)機吹入(ru)進(jin)風(feng)道(dao)，傳入(ru)箱(xiang)內，形成熱風(feng)循(xun)環， 箱(xiang)體設有(you)對流攪拌技術，溫(wen)度非常均勻，具有(you)自動控(kong)溫(wen)，調速，故障報警(jing)等特點，使(shi)用(yong)安全，方便，環保，節(jie)能(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(you)質鐵氟龍耐高溫(wen)網帶(dai)，另(ling)有控(kong)制器(qi)(qi)，調速器(qi)(qi)，低壓電器(qi)(qi)控(kong)制系統(tong)(tong)等控(kong)制系統(tong)(tong)部分。
