Manufacture and Development of a Small Threshing Machine
This study was conducted to manufacture a miniature version of the widespread threshing machine in Egypt and to evaluate its performance. The threshing machine was manufactured at Tanta Motors factory (Emagro), and its performance was evaluated at Etay El Baroud Agricultural Research Station in 2020 in two independent experiments according to the threshed crop. The crops of soybean and dry bean were threshed at different drum speeds of 350, 400, 450 and 500 rpm (9.34, 10.67, 12.01 and 13.34 m/s) and three feeding rates of 300, 400 and 500 kg/h for performance evaluation. The results indicated that the drum speed of 450 rpm (12.01 m/s) and feeding rate of 500 kg/h were the optimum for both crops, as the lowest criterion costs of 948 and 908.4 L.E/Mg were achieved for soybean and dry bean respectively. Also; the threshing efficiency of 98.03% and 97.79%, seed damage of 2.72% and 2.55%, cleaning efficiency of 97.77% and 97.61%, specific consumed energy of 37.93 and 35.41 kWh/Mg and private cost (operating and fixed costs) of 526.5 and 480 L.E/Mg were obtained with soybean and dry bean respectively.
