喷雾干燥机是一种可以同时完成干燥和造粒的装置。按工艺要求可以 料液泵的压力、流量、喷孔的大小,得到所需的按一定大小比例的球形颗粒。
喷雾干燥机为连续式常压干燥器的一种。用特殊设备将液料喷成雾状,使其与热空气接触而被干燥。用于干燥有些热敏性的液体、悬浮液和粘滞液体,如牛奶、蛋、单宁和药物等。也用于干燥燃料、中间体、肥皂粉和无机盐等。
空气经过滤和加热,进入干燥器顶部空气分配器,热空气呈螺旋状均匀地进入干燥室。料液经塔体顶部的高速离心雾化器,(旋转)喷雾成极细微的雾状液珠,与热空气并流接触在极短的时间内可干燥为成品。成品连续地由干燥塔底部和旋风分离器中输出,废气由引风机排空
干燥速度快,料液经雾化后表面积大大增加,在热风气流中,瞬间就可蒸发95%-98%的水份,完成干燥时间仅需数秒钟,特别适用于热敏性物料的干燥。
产品具有良好的均匀度、流动性和溶解性,产品纯度高,质量好。生产过程简化,操作控制方便。对于含湿量40-60%(特殊物料可达90%)的液体能一次干燥成粉粒产品,干燥后不需粉碎和筛选,减少生产工序,提高产品纯度。对产品粒径,松密度,水份,在一定范围内可通过改变操作条件进行调整,控制和管理都很方便。
