Effect of moisture content, feed rate and speed on the perpormance indicators of a soybean thresher

Abstract

A modified soybean thresher was evaluated for its performance indicators as influenced by moisture content, feed rate and speed. The performance evaluation was done at 3 levels each of moisture contents and feed rate and 5 levels of speed. Results show that, threshing and cleaning efficiency of 99%and 95%, respectively,scatter loss of 2.7%, mechanical grain damage of 1.01% and grain throughput capacity of 25.5kg/hr were obtained. Moisture content, feed rate and speed had significant effects on threshing and cleaning efficiency, scatter loss, mechanical grain damage and throughput capacity of the soybean thresher. It is recommended that in order to obtain good performance of the soybean thresher, the optimum moisture content of the material to be threshed is 14%.
