Efficiency of air dehumidification on the drying process in a food plant.

To reduce the proliferation of bacteria inside a food plant, cleaning and disinfection are performed every day. These operations are followed by drying which has to be as quick as possible. This study shows the influence of a dehumidifier on the water mass evolutions on the surfaces such as floor, wall and equipment during the drying of a food plant. The temperature, relative humidity and water mass evolution during drying period were monitored in a food plant running under two conditions: with and without dehumidifier. The results comparison shows that drying rate is about 1.5 times higher with dehumidifier.

为抑制食品工厂内部的细菌增殖，需每日开展清洁与消毒作业，后续需尽快完成干燥工序。本研究针对食品工厂干燥阶段，探究了除湿机对地面、墙面及设备等表面水分质量演变的影响。本研究在启用除湿机与未启用除湿机两种工况下运行的食品工厂中，监测了干燥期间的温度、相对湿度以及各表面的水分质量变化情况。结果对比显示，启用除湿机时的干燥速率约为未启用时的1.5倍。
