Abstract

A solar drying system suitable for agricultural and marine products have been designed, constructed and evaluated under Malaysia climatic conditions. The solar drying system has been constructed and evaluated for the drying of seaweed Gracilaria changii. The initial and final moisture content of seaweed are 95% (wet basis) and 10% (product basis), respectively. The drying time was about 7 hours at average solar radiation of 593 W/m2 and air flow rate of 0.0613 kg/s. Three different thin-layer drying models were compared with experimental data, during the drying of seaweed using the solar drying system at average temperature and humidity of about 50oC and 20%, respectively. The one with highest R2 and lowest MBE and RMSE was selected to better estimate the drying curves. The study showed that the Page model was better fit to drying seaweed compared to the other models (Newton model, and Henderson and Pabis model).
