摘要
我国南北方相对湿度差别较大,相对湿度大会给喷雾干燥生产带来不利影响,如生产时进风温度偏低;塔壁挂粉严重;产品水分含量超标;生产效率降低。相对湿度是设计喷雾干燥系统的重要参数,设计喷雾干燥系统应根据当地环境相对湿度情况进行区别对待。仅以RGYP01-500型立式压力喷雾干燥塔生产奶粉为例进行阐述。
In our country, referred to relative humidity (RH), there is a wide gap between the south and the north. High relative humidity brings bad effect on spray drying. It includes lower intake air temperature when in production, serious powder hanging in tower tall, too much moisture content in product, lower production effeciency.We must design the spray humidity system on the basisi of relative humidity, as it is a key parameter. Taking the vertical pressure spray drying tower RGYP01-500 for milk powder making as an example to elaborate.
