摘　　要：我国南北方相对湿度差别较大,相对湿度大,绝对湿含量过高会给喷雾干燥生产带来不利影响,如不调节进风温度有可能造成塔壁挂粉严重、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。现以RGYP01-500型立式压力喷雾干燥塔生产奶粉为例进行阐述。Large relative moisture and high absolute moisture will give unfavorable influence to spray drying in production. If the temperature of air at inlet is not adjusted, serious hanging powder on wall, extra water in product and low production efficiency will occur. Thus, relative moisture is important parameter in design of spray drying system. In this article, exampled with RGYP01-500 vertical pressure spray drying tower which is used in production of milk powder, the influence of relative moisture was described.
