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。其主要工作(zuo)原(yuan)理是在上下(xia)(xia)鋼(gang)帶夾緊的(de)情況下(xia)(xia)，用預(yu)熱(re)管預(yu)熱(re)單板(ban)，鋼(gang)帶與單板(ban)的(de)溫(wen)度趨于一致。

  然后在干(gan)燥(zao)滾筒之(zhi)間快速干(gan)燥(zao)，使單(dan)(dan)(dan)板(ban)(ban)干(gan)燥(zao)后光滑，含水率均(jun)勻，可大(da)大(da)提高(gao)干(gan)燥(zao)質量和干(gan)燥(zao)效(xiao)率。它具有(you)高(gao)溫滾筒與濕(shi)單(dan)(dan)(dan)板(ban)(ban)直接(jie)接(jie)觸傳熱(re)(re)、熱(re)(re)效(xiao)率高(gao)、熱(re)(re)損(sun)失小的特點，大(da)大(da)降低了(le)熱(re)(re)損(sun)失。2.干(gan)燥(zao)系統(tong)采用(yong)更(geng)科學的干(gan)燥(zao)原理。熱(re)(re)風爐(lu)內的熱(re)(re)風通(tong)(tong)(tong)過(guo)離心(xin)式風扇直接(jie)注入機(ji)器的上下(xia)(xia)波紋管，熱(re)(re)風通(tong)(tong)(tong)過(guo)上、下(xia)(xia)波紋管的噴(pen)嘴吹(chui)到單(dan)(dan)(dan)板(ban)(ban)的上、下(xia)(xia)兩面。單(dan)(dan)(dan)板(ban)(ban)加熱(re)(re)均(jun)勻，以便干(gan)燥(zao)。3.刨單(dan)(dan)(dan)板(ban)(ban)驅(qu)動(dong)系統(tong)通(tong)(tong)(tong)過(guo)進料口縱向進給機(ji)器，鏈條驅(qu)動(dong)上、下(xia)(xia)兩排滾子，相對運行。單(dan)(dan)(dan)板(ban)(ban)由上輥的自重壓力單(dan)(dan)(dan)板(ban)(ban)向前移動(dong)，單(dan)(dan)(dan)板(ban)(ban)通(tong)(tong)(tong)過(guo)兩輥和上下(xia)(xia)空氣噴(pen)嘴，同時達到干(gan)燥(zao)和熨(yun)燙(tang)的效(xiao)果(guo)。因此，這臺(tai)機(ji)器的單(dan)(dan)(dan)板(ban)(ban)是(shi)光滑的，沒有(you)痕跡。
