| Abstract | The overall objective of this study is to develop a thermal storage component for a solar biomass hybrid drying system. The component uses sand as a storage medium in sensible heat storage process. Storage component was integrated in the drying system which consists of solar collector, biomass burning chamber, sand bed with heat exchanger placed inside as a thermal storage component, blower and drying chamber. Theoretical study was carried out and components of the dryer were fabricated. Experiments for individual component and the dryer were conducted. Mathematical models were developed for the dryer to predict the temperature profile of the sand bed and drying air, heat loss in drying chamber. The input parameters were feeding rate, weight of sand, size of heat exchanger, flow rate from solar collector and bottom part. Models for burning chamber and solar collector were applied from literature review. The system was developed properly using heat from two heat sources: solar and biomass. It can be operated in solar-only, biomass-only and hybrid mode. Sand bed provides thermal storage effect for long time after stop burning. |
