Development and evaluation of a solar drier for grains associated to underground bin

摘要

A batch-type, solar-heated air drier with mechanical system of unloading was tested in drying edible beans (Phaseolus vulgaris, L.). Reductions in drying time and area, reached 83 and 76%, respectively, as compared with the natural drying process. A hand-driven mechanical unloading system incorporated allows 95% reduction in unloading time.
