hA warehouse dryer which uses non-conventional energy sources, a center-tube furnace fuelled with combustible agricultural residues as a heat source for drying and a vortex wind machine as the power source for moving air inside a warehouse has been developed. Alternative construction materials such as soil bricks for the furnace, soil-straw blocks for the warehouse wall, and water-proofing finish for the wall were adopted. A vertical tray was also utilized for higher energy efficiency and maximum space utilization. The drying system was evaluated using paddy, corn, coconut meat, fish, abaca, peanut, and cassava. Results of the evaluation presented describe the drying phenomena in a warehouse drying system and the characteristics of the dried product. Cost analysis showed that by using this dryer a ton of paddy can be dried from 25 to 14 percent moisture content at a cost of $0.98 to 1.05. The annual cost is covered by drying at least 540 to 610 tons of paddy per year. At this rate, the initial investment can be recovered in less than four ye
