The design of a modernized cassava peeling machine was carried out in this paper. The principles of engineering design and application using a motorized screw mechanism of helical metal wires were adopted on a rigid shaft powered by an electrical motor of 1 Hp and applied in the design of the peeling chamber which is cylindrical in shape. The peeling drum was designed with 1.5 mm thick steel flat sheet. The total mass of cassava per batch in the peeling drum was designed to be 20 kg with weight of 196.2 N occupied in a peeling chamber of volume 0.978136m3. For 30 minutes of peeling, the peeling force required, is 8.437N when the velocity is 25.31m/s. The torque made by the shaft at the peeling chamber is 2.374 Nm and torsional stress of the shaft was found to be 6.88 x 105 N/m2. The efficiency of the machine was designed to be 80% at a power output of 42.28 Watt.
