單板烘干機是單板和膠合板生產過程中的主要設備之一。單板干燥質量的好壞直接影響到單板和膠合板產品的質量，也直接影響到輥壓式連續單板干燥機的(de)設計。其主(zhu)要工作原理是在上(shang)下鋼(gang)帶夾緊的(de)情況下，用預(yu)熱管預(yu)熱單板，鋼(gang)帶與單板的(de)溫度(du)趨于一致。

  然后在干(gan)(gan)燥(zao)(zao)滾(gun)筒(tong)之間快速干(gan)(gan)燥(zao)(zao)，使單(dan)板(ban)(ban)(ban)(ban)干(gan)(gan)燥(zao)(zao)后光滑(hua)(hua)，含水率(lv)均(jun)勻，可大(da)(da)大(da)(da)提(ti)高干(gan)(gan)燥(zao)(zao)質量和(he)干(gan)(gan)燥(zao)(zao)效率(lv)。它具有(you)高溫滾(gun)筒(tong)與濕單(dan)板(ban)(ban)(ban)(ban)直接接觸(chu)傳熱(re)、熱(re)效率(lv)高、熱(re)損(sun)失小的(de)特(te)點，大(da)(da)大(da)(da)降低了熱(re)損(sun)失。2.干(gan)(gan)燥(zao)(zao)系統(tong)采用更科(ke)學的(de)干(gan)(gan)燥(zao)(zao)原理。熱(re)風(feng)(feng)爐內(nei)的(de)熱(re)風(feng)(feng)通(tong)(tong)過(guo)(guo)離心式風(feng)(feng)扇直接注入機器的(de)上下波紋管，熱(re)風(feng)(feng)通(tong)(tong)過(guo)(guo)上、下波紋管的(de)噴嘴(zui)吹(chui)到單(dan)板(ban)(ban)(ban)(ban)的(de)上、下兩面(mian)。單(dan)板(ban)(ban)(ban)(ban)加熱(re)均(jun)勻，以(yi)便干(gan)(gan)燥(zao)(zao)。3.刨單(dan)板(ban)(ban)(ban)(ban)驅動(dong)系統(tong)通(tong)(tong)過(guo)(guo)進料(liao)口(kou)縱向進給(gei)機器，鏈條(tiao)驅動(dong)上、下兩排滾(gun)子，相對運行。單(dan)板(ban)(ban)(ban)(ban)由(you)上輥的(de)自重(zhong)壓力單(dan)板(ban)(ban)(ban)(ban)向前移動(dong)，單(dan)板(ban)(ban)(ban)(ban)通(tong)(tong)過(guo)(guo)兩輥和(he)上下空氣噴嘴(zui)，同時達到干(gan)(gan)燥(zao)(zao)和(he)熨燙的(de)效果。因此，這臺機器的(de)單(dan)板(ban)(ban)(ban)(ban)是光滑(hua)(hua)的(de)，沒有(you)痕(hen)跡。
