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(ji)。其主要工作原理(li)是在(zai)上下(xia)鋼帶夾(jia)緊的情況下(xia)，用預(yu)熱管(guan)預(yu)熱單(dan)(dan)板(ban)，鋼帶與單(dan)(dan)板(ban)的溫(wen)度趨于一致。

  然后(hou)在(zai)干(gan)燥(zao)(zao)滾(gun)筒之間快速干(gan)燥(zao)(zao)，使單(dan)(dan)(dan)板(ban)(ban)(ban)干(gan)燥(zao)(zao)后(hou)光滑，含水率(lv)均(jun)勻，可(ke)大大提高干(gan)燥(zao)(zao)質量(liang)和(he)干(gan)燥(zao)(zao)效率(lv)。它具有高溫滾(gun)筒與濕單(dan)(dan)(dan)板(ban)(ban)(ban)直接接觸傳熱、熱效率(lv)高、熱損失(shi)小的特點，大大降低了熱損失(shi)。2.干(gan)燥(zao)(zao)系統采用更科(ke)學的干(gan)燥(zao)(zao)原理。熱風(feng)(feng)爐(lu)內(nei)的熱風(feng)(feng)通(tong)過(guo)(guo)離心式(shi)風(feng)(feng)扇(shan)直接注入機器(qi)的上(shang)(shang)下(xia)(xia)(xia)波紋(wen)管，熱風(feng)(feng)通(tong)過(guo)(guo)上(shang)(shang)、下(xia)(xia)(xia)波紋(wen)管的噴嘴(zui)吹到單(dan)(dan)(dan)板(ban)(ban)(ban)的上(shang)(shang)、下(xia)(xia)(xia)兩面(mian)。單(dan)(dan)(dan)板(ban)(ban)(ban)加(jia)熱均(jun)勻，以便干(gan)燥(zao)(zao)。3.刨單(dan)(dan)(dan)板(ban)(ban)(ban)驅(qu)動(dong)系統通(tong)過(guo)(guo)進(jin)料口縱向進(jin)給機器(qi)，鏈條驅(qu)動(dong)上(shang)(shang)、下(xia)(xia)(xia)兩排滾(gun)子，相對運行。單(dan)(dan)(dan)板(ban)(ban)(ban)由上(shang)(shang)輥(gun)的自重壓力單(dan)(dan)(dan)板(ban)(ban)(ban)向前移動(dong)，單(dan)(dan)(dan)板(ban)(ban)(ban)通(tong)過(guo)(guo)兩輥(gun)和(he)上(shang)(shang)下(xia)(xia)(xia)空氣(qi)噴嘴(zui)，同(tong)時達到干(gan)燥(zao)(zao)和(he)熨燙的效果。因此，這臺(tai)機器(qi)的單(dan)(dan)(dan)板(ban)(ban)(ban)是光滑的，沒有痕跡。
