Abstract
BSTRACT Drying of agro products in open air is reducing the quality losses. The direct sunlight drying process take long time and it’s subjected to attack by the weather, animals and insects. It’s also affect the quality, quantity and nutrition value of the food products. So use the solar dryer to dry the agricultural products. At, present renewable energies are increased energy efficiency play an important role in energy politics. Renewable energies are an important approach to reduce the environmental effect. So to use the solar energy to dry the agricultural products. This project aim is investigate the performance of solar dryer using semi-circular solar absorber with heat storing materials and thermal analysis of the solar absorber plate. This project designed such a way that solar radiation is not incident directly on the food product. The sunlight is absorb by the solar absorber (GI) plate, and heat is send through (GI) tube by forced convection and electric air blower to dry the agricultural products in
drying chamber. The (GI) is immersed in heat storing materials (charcoal or gravels).This heat storing materials store the heat at sun shining and transfer the heat to drying chamber to dry the agricultural products.
