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計。其主要(yao)工作原(yuan)理是在(zai)上(shang)下鋼帶夾緊的情況下，用預(yu)熱管預(yu)熱單(dan)板，鋼帶與單(dan)板的溫度趨(qu)于一致。

  然后(hou)在干(gan)燥(zao)(zao)滾筒(tong)之間快速(su)干(gan)燥(zao)(zao)，使單(dan)(dan)(dan)板(ban)(ban)(ban)(ban)干(gan)燥(zao)(zao)后(hou)光滑，含水率均勻(yun)，可(ke)大(da)大(da)提高(gao)干(gan)燥(zao)(zao)質(zhi)量和干(gan)燥(zao)(zao)效(xiao)(xiao)率。它具有高(gao)溫滾筒(tong)與濕(shi)單(dan)(dan)(dan)板(ban)(ban)(ban)(ban)直接(jie)接(jie)觸(chu)傳(chuan)熱(re)、熱(re)效(xiao)(xiao)率高(gao)、熱(re)損失小的(de)(de)(de)特(te)點，大(da)大(da)降低了熱(re)損失。2.干(gan)燥(zao)(zao)系統(tong)采用更科(ke)學的(de)(de)(de)干(gan)燥(zao)(zao)原理(li)。熱(re)風(feng)爐(lu)內(nei)的(de)(de)(de)熱(re)風(feng)通(tong)(tong)過(guo)離(li)心(xin)式風(feng)扇(shan)直接(jie)注入機(ji)器的(de)(de)(de)上下(xia)(xia)波(bo)紋管，熱(re)風(feng)通(tong)(tong)過(guo)上、下(xia)(xia)波(bo)紋管的(de)(de)(de)噴嘴吹到單(dan)(dan)(dan)板(ban)(ban)(ban)(ban)的(de)(de)(de)上、下(xia)(xia)兩面。單(dan)(dan)(dan)板(ban)(ban)(ban)(ban)加熱(re)均勻(yun)，以便干(gan)燥(zao)(zao)。3.刨(bao)單(dan)(dan)(dan)板(ban)(ban)(ban)(ban)驅(qu)動(dong)(dong)系統(tong)通(tong)(tong)過(guo)進(jin)(jin)料(liao)口縱向進(jin)(jin)給(gei)機(ji)器，鏈條驅(qu)動(dong)(dong)上、下(xia)(xia)兩排滾子(zi)，相(xiang)對運(yun)行(xing)。單(dan)(dan)(dan)板(ban)(ban)(ban)(ban)由上輥(gun)的(de)(de)(de)自重(zhong)壓力單(dan)(dan)(dan)板(ban)(ban)(ban)(ban)向前移動(dong)(dong)，單(dan)(dan)(dan)板(ban)(ban)(ban)(ban)通(tong)(tong)過(guo)兩輥(gun)和上下(xia)(xia)空氣噴嘴，同時達到干(gan)燥(zao)(zao)和熨燙(tang)的(de)(de)(de)效(xiao)(xiao)果。因此，這(zhe)臺(tai)機(ji)器的(de)(de)(de)單(dan)(dan)(dan)板(ban)(ban)(ban)(ban)是光滑的(de)(de)(de)，沒有痕(hen)跡。
