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)下鋼帶夾(jia)緊的(de)情況下，用預熱管預熱單板(ban)，鋼帶與單板(ban)的(de)溫度趨于一(yi)致。

  然后(hou)在干(gan)(gan)燥(zao)(zao)(zao)滾筒之間快速干(gan)(gan)燥(zao)(zao)(zao)，使單(dan)板(ban)(ban)(ban)(ban)(ban)干(gan)(gan)燥(zao)(zao)(zao)后(hou)光(guang)滑，含水(shui)率均勻，可大(da)(da)大(da)(da)提高(gao)干(gan)(gan)燥(zao)(zao)(zao)質量(liang)和干(gan)(gan)燥(zao)(zao)(zao)效率。它具有高(gao)溫滾筒與濕單(dan)板(ban)(ban)(ban)(ban)(ban)直接接觸傳熱(re)(re)、熱(re)(re)效率高(gao)、熱(re)(re)損(sun)失小的特(te)點，大(da)(da)大(da)(da)降低(di)了熱(re)(re)損(sun)失。2.干(gan)(gan)燥(zao)(zao)(zao)系統采(cai)用更科學的干(gan)(gan)燥(zao)(zao)(zao)原理。熱(re)(re)風(feng)爐內的熱(re)(re)風(feng)通(tong)過(guo)(guo)(guo)離心式風(feng)扇直接注入(ru)機(ji)器(qi)的上(shang)下波紋管，熱(re)(re)風(feng)通(tong)過(guo)(guo)(guo)上(shang)、下波紋管的噴嘴吹到單(dan)板(ban)(ban)(ban)(ban)(ban)的上(shang)、下兩面(mian)。單(dan)板(ban)(ban)(ban)(ban)(ban)加熱(re)(re)均勻，以便(bian)干(gan)(gan)燥(zao)(zao)(zao)。3.刨單(dan)板(ban)(ban)(ban)(ban)(ban)驅動(dong)系統通(tong)過(guo)(guo)(guo)進料口縱向(xiang)進給機(ji)器(qi)，鏈條驅動(dong)上(shang)、下兩排(pai)滾子，相對運(yun)行。單(dan)板(ban)(ban)(ban)(ban)(ban)由上(shang)輥(gun)(gun)的自重壓力單(dan)板(ban)(ban)(ban)(ban)(ban)向(xiang)前(qian)移動(dong)，單(dan)板(ban)(ban)(ban)(ban)(ban)通(tong)過(guo)(guo)(guo)兩輥(gun)(gun)和上(shang)下空氣噴嘴，同時達到干(gan)(gan)燥(zao)(zao)(zao)和熨燙的效果。因(yin)此，這臺機(ji)器(qi)的單(dan)板(ban)(ban)(ban)(ban)(ban)是光(guang)滑的，沒有痕跡。
