二手(shou)滾(gun)筒干燥機工作原理

二手滾筒干燥機

滾筒(tong)干(gan)(gan)燥(zao)機的(de)轉(zhuan)(zhuan)筒(tong)是略帶傾(qing)斜(xie)并能回轉(zhuan)(zhuan)的(de)圓(yuan)筒(tong)體，濕物(wu)料(liao)從(cong)(cong)一端上(shang)部(bu)進入(ru)，干(gan)(gan)物(wu)料(liao)從(cong)(cong)另一端下部(bu)收集。熱風(feng)從(cong)(cong)進料(liao)端或出料(liao)端進入(ru)，從(cong)(cong)另一端上(shang)部(bu)排(pai)出。筒(tong)內裝(zhuang)有(you)順向抄板，使(shi)物(wu)料(liao)在筒(tong)體回轉(zhuan)(zhuan)過程中不斷抄起又灑下，使(shi)其充分與熱氣流接觸，以提高(gao)(gao)干(gan)(gan)燥(zao)效(xiao)率(lv)并使(shi)物(wu)料(liao)向前移動(dong)。干(gan)(gan)燥(zao)物(wu)料(liao)熱源一般為熱空(kong)氣、高(gao)(gao)溫煙(yan)道氣、水蒸氣等。

二手(shou)滾筒(tong)干燥機(ji)工作原(yuan)理(li)

滾(gun)(gun)(gun)筒(tong)(tong)(tong)干(gan)燥(zao)機(ji)的(de)工(gong)作過程為(wei)：需要干(gan)燥(zao)處理的(de)料(liao)(liao)(liao)液由(you)高位槽流人滾(gun)(gun)(gun)筒(tong)(tong)(tong)干(gan)燥(zao)器的(de)受料(liao)(liao)(liao)槽內，由(you)布膜裝置使物(wu)料(liao)(liao)(liao)薄薄地(di)（膜狀）附在(zai)(zai)滾(gun)(gun)(gun)筒(tong)(tong)(tong)表面，滾(gun)(gun)(gun)筒(tong)(tong)(tong)內通有供熱(re)介質，食品工(gong)業(ye)多采用蒸汽，壓(ya)力一(yi)般在(zai)(zai)0.2～6MPa，溫(wen)度在(zai)(zai) 120～150℃之間，物(wu)料(liao)(liao)(liao)在(zai)(zai)滾(gun)(gun)(gun)筒(tong)(tong)(tong)轉動(dong)中(zhong)由(you)簡壁(bi)傳熱(re)使其濕分汽化，滾(gun)(gun)(gun)簡在(zai)(zai)一(yi)個轉動(dong)周期中(zhong)完(wan)成布膜、汽化、脫水等過程，干(gan)燥(zao)后(hou)的(de)物(wu)料(liao)(liao)(liao)由(you)刮刀刮下，經螺旋輸(shu)送至成品貯存槽，zui后(hou)進(jin)行(xing)粉碎或(huo)直接包裝。在(zai)(zai)傳熱(re)中(zhong)蒸發(fa)出的(de)水分，視(shi)其性(xing)質可通過密閉(bi)罩(zhao)，引入到相應的(de)處理裝置內進(jin)行(xing)捕集粉塵或(huo)排放。
