An indirect passive convectional solar dryer consisting of a solar air heater and dryer chamber is designed, manufactured and tested for its performance. It plays a major role in reducing crop wastage and opens a way to food preservation. The area of the solar collector required to dry a batch of 10 kg of tomato within two days is calculated. The performance of the collector is improved through the use corrugated absorber to create turbulence for air flow and a highly insulating material to minimize heat losses. The thermal performance of the solar dryer is tested under the local weather …
