AbstractA power operated groundnut sheller with reciprocating shelling mechanism designed earlier had a capacity of about 175 kg(seed)/h, 97% shelling efficiency, 4.7% breakage and power consumption about 12.6 kwh/ton. To reduce power consumption a sheller with rotary shelling mechanism was designed and tested. The shelling bar speed was varied from 100 to 220 rpm and clearance was varied from 10 to 26 mm. the best performance of the sheller was achieved at 180 rpm shelling bar speed and 20 mm clearance. The shelling capacity, shelling efficiency, and breakage were 219 kg/h, 98.03%, and 5.37% respectively. The blower shaft speed was varied from 1000 to 1500 rpm and the blower chute angle was varied from 30 to 45 degree. the best performance was achieved at 1200 rpm blower shaft speed and 35 degree of blower chute angle. The loss of kernels due to cleaning mechanism amounted to 0.78% and had 99.94% cleaning efficiency. During the work performance tests with optimum settings, the shelling capacity and power consumption were 228 kg(seed)/h or 308 kg(pod)/h and 4.8kwh/ton respectively. Thus this rotary sheller has higher capacity and consumes less power than the reciprocating sheller. The minimum annual use for the ownership of the power sheller is about 3 tons. The manual sheller should be replaced by the power operated sheller when the annual use is more than 7 tons.
