【 摘 要 】

The project goal is to develop the world's best grain dryer, where best is defined in terms of energy efficiency, grain quality protection, and minimal environmental impact. A technique was developed to recapture enthalpy from a continuous flow drying system and to carry that energy back into the grain kernels. Process design assures that the recaptured energy is used to provide latent heat for evaporation of moisture from the kernels. Maximum kernel temperatures are tightly controlled by the design and can be selected through the system controls. The drying system process has been simulated, the mechanical design for a prototype was completed, and the prototype has been fabricated and installed. Simulation results show energy use that is a fraction of that required by the most efficient heat assisted grain dryer systems available at this time. Unfortunately, project time has expired, funding has been exhausted, and the system has yet to be fully run in order to validate the process design. Additional development work is required to run tests with the prototype, improve the simulation model, optimize the process and mechanical design, and bring this energy saving system to market.
