Description

The results of a study to verify the technical feasibility of the regenerated desiccant crop drying concept, characterize its performance, investigate design requirements, and define a pilot facility for further evaluating the operational and energy-conservative characteristics of the drying system are documented. The pilot facility defined in this study will be a use R and D tool of sufficient size to permit a meaningful evaluation of the system and to provide the necessary criteria for development of full-scale systems. The principal finding of the study is that the regenerated desiccant crop drying concept is technically feasible and has the capability … continued below

Description

The results of a study to verify the technical feasibility of the regenerated desiccant crop drying concept, characterize its performance, investigate design requirements, and define a pilot facility for further evaluating the operational and energy-conservative characteristics of the drying system are documented. The pilot facility defined in this study will be a use R and D tool of sufficient size to permit a meaningful evaluation of the system and to provide the necessary criteria for development of full-scale systems. The principal finding of the study is that the regenerated desiccant crop drying concept is technically feasible and has the capability to achieve a drying efficiency of approximately twice that of conventional crop drying systems. When using a fossil fuel energy source, energy savings will be approximately 40 to 50%. With solar energy input, the total fossil fuel savings could be 70 to 90%. The economic feasibility of the system appears promising. As with other new energy conserving systems that are presently capital-intensive, the economic viability of the system will be dependent on future capital cost reductions, on the future price of fossil fuels, and on the specific application of the system. Regarding system applications, it was concluded that the regenerated desiccant drying system, with or without the use of solar energy, will be economically best suited for a large central processing application, where it can receive a maximum amount of use and will benefit from economy-of-scale cost considerations. The basic study recommendations are: (1) additional R and D activities should be conducted to identify and evaluate means for achieving system cost reductions, and (2) the Mobile Pilot Facility program should be initiated.
