Abstract
A solar photovoltaic (SPV) powered paddy winnower was developed and evaluated at CAET, BSKKV, Dapoli. In order to eliminate the operational problems and difficulties, it was proposed to modify the existing SPV power operated paddy winnower, for better and improved performance. The existing SPV operated paddy winnower was tested to find the operational difficulties, and the physical properties of different paddy verities i.e., Ratnagiri-1, Ratnagiri-6, karjat-3. Including the terminal velocity, angle of repose, bulk density. It was found that improving several parameters can eliminate the operational difficulties from the existing SPV operated paddy winnower. The necessary modifications were incorporated in a modified SPV operated paddy winnower. The modified SPV operated paddy winnower was tested for Ratnagari-1 Variety of paddy and its improved performances were reported.
