廣東紅寶(bao)機(ji)械攪(jiao)拌干燥機(ji)創新采(cai)用“雙回路熱(re)(re)交(jiao)換(huan)(huan)”系統，實(shi)現加熱(re)(re)/冷(leng)(leng)(leng)卻介質15秒內快(kuai)速切換(huan)(huan)。設備配備導(dao)熱(re)(re)油與冷(leng)(leng)(leng)卻水雙進口管路，通(tong)(tong)過電磁三通(tong)(tong)閥自動(dong)切換(huan)(huan)，在干燥階段通(tong)(tong)入200℃導(dao)熱(re)(re)油，物(wu)料(liao)(liao)含水率達標(biao)后立即(ji)切換(huan)(huan)15℃冷(leng)(leng)(leng)卻水，使物(wu)料(liao)(liao)溫(wen)度從100℃降(jiang)至40℃僅需15分(fen)鐘，縮短冷(leng)(leng)(leng)卻周期60%。在橡膠助劑干燥中(zhong)，快(kuai)速冷(leng)(leng)(leng)卻避免物(wu)料(liao)(liao)二次結晶(jing)，產品粒徑分(fen)布標(biao)準(zhun)差控制在0.5μm內。系統還支(zhi)持“加熱(re)(re)-冷(leng)(leng)(leng)卻-保(bao)溫(wen)”循環模式，如(ru)在環氧樹脂固化(hua)工藝中(zhong)，先加熱(re)(re)至80℃保(bao)溫(wen)2小時，再冷(leng)(leng)(leng)卻至50℃出料(liao)(liao)，全(quan)程溫(wen)度波動(dong)≤±1℃，滿(man)足(zu)精(jing)細化(hua)生產對溫(wen)度曲線的嚴苛要求。
