초록

Drying process is involved in the production of various products including food, textiles, paper, pharmaceuticals, and batteries. Phase change of liquid to vapor generally requires enormous thermal energy, so in order to save energy, it is advantageous to develop an appropriate drier and use it under appropriate operating conditions, depending on the characteristics of materials. However, due to the complex, multiscale heat and mass transfer occurring during drying processes, predictions of appropriate drying conditions before actual operation are not easily achieved, leading to challenges in designing driers. Here, we developed a lab-scale experimental setup to evaluate the performance of band dries. The experimental setup was used to measure the moisture content and temperature change in the materials being dried in a belt dryer. Experimental results obtained using our lab-scale setup allow us to predict the performance of a full-scale band drier, thus suggesting a practical framework for predicting the drying process of various materials and developing band driers.
