Abstract :

A locally constructed groundnut sheller (Dan yamel) was modified. The modified sheller consist of shelling unit which comprised of a hopper with feed control and shelling chamber made of a rasp bar, a cleaning unit, and a prime mover. The sheller operates on a single belt drive system. The performance test of the modified sheller was carried out using Ex-Dakar groundnut variety with a moisture content of 8%. A feed rate of 300 kg/hr and shelling speed of 180 rpm were used during the test. The performance indices obtained were significantly improved after the modification except for the output capacity which was slightly increased. The modified sheller has an output capacity, shelling efficiency, cleaning efficiency, mechanical damage, and scatter loss of 239.81 kg/hr, 98.32%, 50.63%, 4.33 %, and 3.24%, respectively as against 233.18 kg/hr, 86.19%, 8.11%, and 9.52%, respectively recorded with the old sheller.
