Development of a Cassava Grating Machine

Developing of a cassava grating machine is presented. This is a great boost in the development of local content and reduction of wastage in cassava produce in Africa. The use of internal combustion engine in powering the cassava grating machine makes the study unique as it goes a long way in eliminating the undue stress involved manual grating of cassava tubers. The developed machine is made up of components such as hopper, pulley belts, grating unit, internal combustion engine and shaft. Scientific formulae were employed to aid the design of the cassava grating machine. A detailed graphical modeling was done to serve as a guide for the fabrication of the machine. The developed grating machine had a volumetric capacity of hopper to be 50272000 mm3. A power capacity of 1.715 KW was delivered to the solid shaft of 27.05 mm diameter to grate the peeled cassava tubers at a designed torque of 10.23 Nm.
