利用传热传质方程得出干燥介质的湿球温度,在物料充分湿润的情况下,可将恒速段物料温度认为是干燥介质的湿球温度,从中得出物料的实际温度。
The temperature of the wet bulb of the drying medium is obtained by using the heat and mass transfer equation. When the material is fully wetted, the temperature of the constant velocity section can be regarded as the wet-bulb temperature of the drying medium, and the actual temperature of the material can be obtained therefrom.
