Agricultural Engineering


Agricultural crop drying provides numerous applications where low to moderate temperature rises can provide a large percentage of the grain drying requirements. The application of solar energy to grain drying depends on the capability of the solar energy system to provide temperature rises and enough heat to increase the rate at which moisture is removed from the wet grain. Current investigations of solar energy utilization for agricultural applications include many variations of solar collectors and solar concentrators. However, data available on the use of solar concentrators for specific agricultural applications in most climatic areas are limited. Because of the great importance of developing alternate energy sources as substitutes for conventional energy sources, research was conducted with the following objectives: 1. Design a solar energy-intensifier system for use in drying shelled corn. 2. Evaluate the thermal efficiency and energy collecting capabilities of a solar energy-intensifier for providing supplemental heat for drying shelled corn under actual climatic conditions.
