Abstract: | An indirect forced convection solar drier integrated with sensible heat storage material has been fabricated and tested for copra drying. It reduces moisture content (wet basis) from 52% to 7.8% and 9.5% in 66 h for trays at bottom and top respectively. System pickup efficiency varies between 45% and 13%. Copra obtained was graded as 76% milling copra grade1 (MCG1), 18% MCG2 and 6% MCG3. Specific moisture extraction rate was estimated to be 0.84 kg/kWh. In sun drying, moisture content reduced from 52.3% (wet basis) to about 9.2% in 7 days. Copra obtained was graded as 53% MCG1, 24% MCG2 and 23% MCG3. Average drier thermal efficiency of sun drying was estimated to be about 21%. |
