Abstract
A portable power paddy thresher was developed for small farmers. A cross flow portable power paddy thresher cum winnower was fabricated based on cylinder- concave mechanism and its performance was assessed in terms of threshing efficiency, grain damage and output capacity and compared with conventional methods of threshing. The portable paddy thresher was field tested and its threshing efficiency, damaged grains and output of the thresher were found to be 99.85 %, 2.85 % and 235.65 kg h-1, respectively. The saving in cost and time of the portable power paddy thresher were 86.5 % and 95 %, respectively as compared to manual threshing. The break-even point for the developed portable power paddy thresher was 205 hours of use per year.
Key words : Paddy threshing, Conventional threshing methods, Power thresher, Threshing efficiency
