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(gong)作原理(li)是(shi)在上下鋼帶夾緊的(de)情(qing)況下，用預熱管預熱單板(ban)，鋼帶與(yu)單板(ban)的(de)溫度趨于一致(zhi)。

  然后(hou)(hou)在干(gan)(gan)燥滾筒之間(jian)快速干(gan)(gan)燥，使(shi)單板(ban)(ban)(ban)干(gan)(gan)燥后(hou)(hou)光(guang)滑，含水(shui)率均勻，可大大提高干(gan)(gan)燥質(zhi)量(liang)和(he)干(gan)(gan)燥效(xiao)率。它具有高溫滾筒與濕(shi)單板(ban)(ban)(ban)直接(jie)接(jie)觸(chu)傳熱(re)、熱(re)效(xiao)率高、熱(re)損失小的特點(dian)，大大降(jiang)低了熱(re)損失。2.干(gan)(gan)燥系(xi)統(tong)采用更科(ke)學的干(gan)(gan)燥原(yuan)理。熱(re)風爐內的熱(re)風通(tong)(tong)(tong)過(guo)離心(xin)式風扇直接(jie)注(zhu)入機(ji)器(qi)的上下(xia)波紋管，熱(re)風通(tong)(tong)(tong)過(guo)上、下(xia)波紋管的噴嘴吹到(dao)單板(ban)(ban)(ban)的上、下(xia)兩面。單板(ban)(ban)(ban)加熱(re)均勻，以(yi)便干(gan)(gan)燥。3.刨單板(ban)(ban)(ban)驅(qu)動系(xi)統(tong)通(tong)(tong)(tong)過(guo)進(jin)料(liao)口縱向進(jin)給機(ji)器(qi)，鏈條驅(qu)動上、下(xia)兩排滾子，相(xiang)對運行(xing)。單板(ban)(ban)(ban)由上輥(gun)的自重壓力單板(ban)(ban)(ban)向前移動，單板(ban)(ban)(ban)通(tong)(tong)(tong)過(guo)兩輥(gun)和(he)上下(xia)空氣(qi)噴嘴，同時達(da)到(dao)干(gan)(gan)燥和(he)熨燙(tang)的效(xiao)果(guo)。因此，這臺機(ji)器(qi)的單板(ban)(ban)(ban)是(shi)光(guang)滑的，沒有痕跡(ji)。
