Multirack foldable solar dryer for Mango flakes

Foldable solar dryer developed and evaluated for Mango flakes drying. Mango fruits were selected as drying material. Time required for reducing the moisture content up to 10 per cent as a safe storage for solar dryer was observed for Mango flakes. Overall collection efficiency was found to be 0.97 %, whereas where pickup efficiency was found to be 15 per cent. Evaluation parameters were collection efficiency, system drying efficiency, pick-up efficiency, moisture ratio and drying rate.
