Experimental Performance of A Rotary Desiccant Wheel Without Honeycomb Matrix Structure: A Preliminary Study

Experimental investigation of a rotary desiccant wheel is presented in this study. The rotary desiccant wheel without honeycomb matrix structure is tested where silica gel is used as the desiccant material. The dehumidification experiment shows the humidity ratio decreased from 0.0205 kg/kg to 0.0182 kg/kg. Due to it has the potential to be a drying machine, an initial drying experiment was also carried out to see the performance of this machine. The drying process shows the machine can reduce the moisture content of the noodle product from 33.86% to 9.95% in 17 hours. Results show that thermal, regeneration, and dehumidification effectiveness is up to 24%, 14% and 11%, respectively.
