补充资料：GSX型闪蒸干燥机
工作原理：
旋转闪蒸干燥机是为了干燥滤饼状、膏糊状、稀泥浆壮物料而专门设计的一种连续干燥设备。洁净的热介质呈切线形式进入干燥室，与机械搅拌机构一起形成强有力的涡旋式旋转气流。湿物料由加料器定量加入干燥室，在搅拌和涡旋气流的作用下被粉碎干燥。干燥室顶部社有粒度分级器，细的粉末从塔顶排出，由后面的分离器收集下来，较大的颗粒重新返回干燥室，继续被粉碎干燥。

性能特点：
广泛适用于含有不溶于水或溶剂的，非晶状或晶状细小颗粒的低粘性淤渣，膏糊，滤饼和半干燥粉末的干燥生产。投料时，不需对物料进行稀释，降低了干燥能耗。操作连续的一级干燥，布局紧凑，操作、清洗容易。干燥过程的传热传质时间短，热损失少.
