Selecting the proper conditions for threshing lentil and bean [electronic resource].

Includes references.

Filed experiments were carried out to select the optimum conditions for threshing both lentil and bean in order to minimize energy consumed and criterion cost under Egyptian conditions. All experiments were conducted under three variables for both lentil and bean four material feed rates of (0. 7, 0. 75, 0.8 and 0.85) Mg/h and (0.6, 0.65, 0. 7 and 0. 75) Mg/h, four drum speeds of 450, 480, 510 and 540 rpm and 460, 490, 520 and 550 rpm and four seed moisture contents (wb) of(14.1, 12.3, 10.6 and 9. 7 %) and (13.5, 12.4, 10.2 and 9.1 %)for lentil and bean, respectively. Threshing machine performance was evaluated in terms of threshing losses, threshing and cleaning efficiency, energy requirements and criterion cost. The experimental results reveal to the following: The suitable feed rates to thresh lentil and bean were 0. 8 and 0. 7 Mg/h, respectively. The proper drum speedfor threshing lentil and bean were 510 and 520 rpm, respectively. The optimum seed moisture content suitable for threshing lentil and bean were 10.6 and 10.2 %, respectively.
