Development of Solar Pneumatic Grain/Seed Cleaning System

This report describes a solar-powered pneumatic grain/seed cleaning system. The report stats that a solar powered pneumatic grain/seed cleaning system was developed with specific functional, structural and operational design parameters. The developed pneumatic cleaner was tested for garden pea, bottle gourd, sponge gourd and radish seed lots of different impurity levels. It was found that the processed lot achieved more than 99% physical purity irrespective of type of seed and impurity levels and the cleaning efficiency of the system was more than 96%.
