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(ji)。其主要工作(zuo)原理是在上(shang)下鋼帶夾緊的(de)情(qing)況(kuang)下，用預熱(re)管預熱(re)單(dan)板，鋼帶與單(dan)板的(de)溫度趨于一致。

  然(ran)后在干燥(zao)(zao)滾筒之間快速干燥(zao)(zao)，使單板(ban)(ban)(ban)(ban)干燥(zao)(zao)后光滑，含水率(lv)均勻，可大(da)(da)大(da)(da)提高干燥(zao)(zao)質量和干燥(zao)(zao)效(xiao)(xiao)率(lv)。它(ta)具有高溫(wen)滾筒與濕(shi)單板(ban)(ban)(ban)(ban)直(zhi)接(jie)接(jie)觸傳熱(re)(re)、熱(re)(re)效(xiao)(xiao)率(lv)高、熱(re)(re)損失小的(de)(de)特點，大(da)(da)大(da)(da)降低了(le)熱(re)(re)損失。2.干燥(zao)(zao)系統(tong)采用更科學的(de)(de)干燥(zao)(zao)原理。熱(re)(re)風(feng)爐(lu)內(nei)的(de)(de)熱(re)(re)風(feng)通(tong)(tong)過(guo)離心式風(feng)扇直(zhi)接(jie)注入機器(qi)(qi)的(de)(de)上(shang)(shang)下(xia)波(bo)紋管(guan)，熱(re)(re)風(feng)通(tong)(tong)過(guo)上(shang)(shang)、下(xia)波(bo)紋管(guan)的(de)(de)噴(pen)嘴吹到單板(ban)(ban)(ban)(ban)的(de)(de)上(shang)(shang)、下(xia)兩面。單板(ban)(ban)(ban)(ban)加熱(re)(re)均勻，以(yi)便干燥(zao)(zao)。3.刨單板(ban)(ban)(ban)(ban)驅動(dong)(dong)系統(tong)通(tong)(tong)過(guo)進料口縱向進給機器(qi)(qi)，鏈(lian)條驅動(dong)(dong)上(shang)(shang)、下(xia)兩排滾子，相(xiang)對運行。單板(ban)(ban)(ban)(ban)由上(shang)(shang)輥的(de)(de)自重壓力單板(ban)(ban)(ban)(ban)向前移動(dong)(dong)，單板(ban)(ban)(ban)(ban)通(tong)(tong)過(guo)兩輥和上(shang)(shang)下(xia)空氣噴(pen)嘴，同時達(da)到干燥(zao)(zao)和熨燙的(de)(de)效(xiao)(xiao)果。因此(ci)，這臺機器(qi)(qi)的(de)(de)單板(ban)(ban)(ban)(ban)是光滑的(de)(de)，沒有痕跡。
