Design and Fabrication of a Cassava Processig Handling Machines

Cassava processing handling machines that involves cassava grating and cassava mash dewatering machines was designed, fabricated and tested. The machines which are easy to operate and maintain has the following components: hopper, grating chamber, discharged outlets, transmission system, power unit and the frame for the cassava grater, and the cassava mash dewatering machine has the hydraulic screw jack, the rigid frame, compression spring and the dewatering chamber. The cassava grater was powered by 2.0 kW, single phase, 1640 rpm electric motor. The grater speeds varied are 1550 rpm, 1450 rpm and 1350 rpm and the results from the performance evaluation of the grating machine showed a higher capacity, improved efficiency and best performance was obtained at 1450 rpm grater speed of grating capacity of 250.45kg/h, throughput of 235.5 kg/h and efficiency of 96.8 %. Also, the dewatering machine has capacity of 400 kg/h and dewatering efficiency of 97.4%. it is therefore, recommended for the producers of garri and cassava products.
