Abstract

Humidity in drying process is a factor that affects how fast the drying process occurs. The thing used to lower the humidity level is desiccant which used to reduce the moisture content in drying process. The purpose of this study is to design a dryer box and the addition of desiccant to determine the performance of the dryer box by determining SMER and SEC during the drying process. The method used in study is directly carried out by utilizing solar energy directly to generate electricity from solar photovoltaics. The results shows that the utilization of desiccant improved the performance of dryer box. The main conclusion of this study convinced that the humidity is a factor to improve drying rate and desiccant was the material used
