Abstract
Solar-biomass hybrid tunnel dryer has been designed to dry different kinds of agricultural products.The dryer is comprised of three major parts, solar collector(inside the drying chamber), backup heating stove and an additional collector connected to the drying chamber through PVC pipes. This study presents the performance evaluation of the dryer. Collector average efficiency was found to be 29.7% and the drying efficiency for the system was 22.8%. The tunnel dryer was run on solar energy and solar-biomass energy for different set of tests. Different types of vegetables and fruits were dried in the tunnel dryer. A total of 7 solar-biomass hybrid tunnel dryer were constructed out of which 6 were installed in Swat KP Pakistan (Regions: Chikrae, Tal sar, Badalae, Jarro, Charbagh and Khwazakhela). Swat being the most effective area in respect of producing fruits. The post harvest losses are high. The total capacity of the dryer was found to be 75Kg. Keywords— Solar drying, Solar-biomass dryer, Hybrid Drying, Temperature, Relative Humidity
