Abstract
A pedal – operated cassava grating machine was developed and evaluated. The grater is to bridge the gap between the motorized grater and the labour-intensive, traditional cassava grating device, and to ameliorate the tedium of cassava grating at the village level. The grater’s component parts are: the grating unit, power and transmission unit, the housing, the hopper and the discharge chute. The cassava grater output capacity ranged between 28.50kg/h and 45.00kg/h depending on cassava variety. The particle size distribution in the end product representing medium fine, fine and powdery materials is 1:3:6. The grater capacity has a comparative advantage ratio of more than 220% over traditional grating device. One average person of between 25 – 45 years of age can comfortably operate the continuously for about 16 minutes to produce an output of about 4kg
