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設(she)計。其主(zhu)要工(gong)作(zuo)原理是(shi)在上(shang)下(xia)鋼帶夾緊的情況下(xia)，用預熱(re)管(guan)預熱(re)單(dan)板，鋼帶與(yu)單(dan)板的溫(wen)度趨于一致。

  然(ran)后(hou)在干燥(zao)(zao)(zao)(zao)滾筒(tong)之間快速干燥(zao)(zao)(zao)(zao)，使單板(ban)(ban)(ban)(ban)(ban)干燥(zao)(zao)(zao)(zao)后(hou)光滑(hua)，含(han)水(shui)率均勻(yun)，可大(da)大(da)提(ti)高(gao)干燥(zao)(zao)(zao)(zao)質量和(he)干燥(zao)(zao)(zao)(zao)效率。它具有高(gao)溫滾筒(tong)與濕單板(ban)(ban)(ban)(ban)(ban)直(zhi)(zhi)接(jie)(jie)接(jie)(jie)觸傳熱(re)(re)(re)、熱(re)(re)(re)效率高(gao)、熱(re)(re)(re)損(sun)(sun)失小的(de)(de)(de)(de)特點，大(da)大(da)降低了(le)熱(re)(re)(re)損(sun)(sun)失。2.干燥(zao)(zao)(zao)(zao)系(xi)(xi)統采用(yong)更科學的(de)(de)(de)(de)干燥(zao)(zao)(zao)(zao)原(yuan)理。熱(re)(re)(re)風(feng)(feng)爐(lu)內的(de)(de)(de)(de)熱(re)(re)(re)風(feng)(feng)通過(guo)離心式(shi)風(feng)(feng)扇(shan)直(zhi)(zhi)接(jie)(jie)注(zhu)入機器的(de)(de)(de)(de)上(shang)(shang)(shang)(shang)下(xia)(xia)(xia)波紋管，熱(re)(re)(re)風(feng)(feng)通過(guo)上(shang)(shang)(shang)(shang)、下(xia)(xia)(xia)波紋管的(de)(de)(de)(de)噴嘴吹到(dao)單板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)上(shang)(shang)(shang)(shang)、下(xia)(xia)(xia)兩(liang)面(mian)。單板(ban)(ban)(ban)(ban)(ban)加熱(re)(re)(re)均勻(yun)，以便干燥(zao)(zao)(zao)(zao)。3.刨單板(ban)(ban)(ban)(ban)(ban)驅動(dong)系(xi)(xi)統通過(guo)進料口縱向進給機器，鏈(lian)條驅動(dong)上(shang)(shang)(shang)(shang)、下(xia)(xia)(xia)兩(liang)排滾子，相對運行。單板(ban)(ban)(ban)(ban)(ban)由上(shang)(shang)(shang)(shang)輥的(de)(de)(de)(de)自重(zhong)壓(ya)力單板(ban)(ban)(ban)(ban)(ban)向前移(yi)動(dong)，單板(ban)(ban)(ban)(ban)(ban)通過(guo)兩(liang)輥和(he)上(shang)(shang)(shang)(shang)下(xia)(xia)(xia)空氣(qi)噴嘴，同時達到(dao)干燥(zao)(zao)(zao)(zao)和(he)熨燙的(de)(de)(de)(de)效果(guo)。因此，這臺機器的(de)(de)(de)(de)單板(ban)(ban)(ban)(ban)(ban)是光滑(hua)的(de)(de)(de)(de)，沒有痕跡。
