| Abstract | Increase in shelling efficiency and capacity, and reduction in the percent breakage and power consumption, were achieved by modifying the front and rear end concave clearances a nd using round bar grate concave instead of wire mesh concave. To reduce breakage shoe rubber sole pads with cushioning material were used in place of tyre pads. A screw mechanism was incorporated to adjust the cylinder concave clearance. Grading assembly comprising of a set of three screens, was designed to facilitate grading of kernels into whole , broken and immature kernels. The best performance of the sheller was achieved at 180 rpm shelling cylinder speed and 18 mm clearance a t 400 kg/hr feed rate a t 1 3 % moisture content . Shelling capacity, shelling ffici8ncy and per cent breakage were 280 kg/ hr, 98. 05 and 4. 53 respectively During the tests with two variable speed motors, the power consumption was a bout 1. 03 kWh, which decrease d to 0. 75 kW h , when only one motor was used. Newly developed pedal sheller consisted of sheller, winnower and grader . Performance tests revealed that 40-45 rpm o f pedaling speed at the clearance of 18 mm and feed rate of 180 kg( pod) / hr giving 80 kg(kernels)/ hr ca p a city was comfortable for the operators for the continuous run of about 2 5 -30 minutes. Overall shelling efficiency and percent breakage we re found to be 98 per cent and less than 3 percent with the power consumption of about 320 watts. By the cost economic estimates it was found that the minimum planted area to own the power sheller should be 3. 68 ha . The manual sheller should be replaced by power one when annual shelling will b e more than 3. 00 ton s/yr. Power tiller engine driven sheller has the lowest operational cost. Pedal sheller could be replaced by the engine operated sheller and electric motor driven sheller at the annual use of 7. 6 a nd 1 5 tons respectively. |
