Evaluation of locally threshing machine performance for threshing lentil crop [electronic resource].

Includes references.

The main objectives of this research are to study the feasibility of cereal threshing machine for dry lentil seed threshing and select the optimum conditions for operating it. Threshing machine performance was investigated as a function of change in drum speeds of 7.85,9.82, 11.78, 13.74, and 15.71 m / sec, feed rates of 10.00, 11.67, 13.13, 15.00, and 16.67 kg /min, and seed moisture contents of 10.31, 12.30, and 14.12 %. The experiments were carried out at the experimental farm of Tag EL-Ezz Research station, Dakahliea Governorate during season 2004 on lentil crop at three different times after hand harvest operation to drying the field. All experiments were conducted using locally thresher machine The obtained results show that, the local threshing machine can be successfully used for threshing lentil crop under the following conditions: feeding rate of 11.67 kg/min and drum speed of 11.78 m / sec at seed moisture content of 10.31 %, resulting in seed damage of 0.62 %, unthreshed seed of 0.15 %, total seed losses of 0.77 %, seed output of 302.1 kg/h, threshing efficiency of 99.79 %, consumed energy of 0.116 kW. h /kg, and criterion cost of85.83 L.E/ton.
