MODIFICATION OF NATURAL CONVECTION SOLAR DRYER.
1.Insulation not proper working condition therefore heat loss through back side.
2.Exhaust fan not joining.
3.Timer not available.
4.Leakage is more.
1.Insulation required at back side of dryer for preventing the heat.
2.Exhaust fan required for removing moist air from product to outside.
3.Timer required for removing excess heat.
4.Removing leakage for proper heat give to the product.
5.collector paint to the black color for absorbing more solar radiation.
6.The energy required to the exhaust fan is collected from the solar panel.
7.Improving efficiency of solar dryer.
1.Removing the dust and cleaning the glass of solar dryer.
2.Collector paint to the black color.therefore black color absorb more radiation and more heat collected inside the collector.
3.Repairing the food cabinet and fitting exhaust fan backside of food cabinet
