ABSTRACT

A  Motorized Cassava Mash Sifter was developed and evaluated. The Sifter is powered by an electric motor; the dimension of the machine is 915mm × 455mm × 630mm.Test results show that the sifter has the highest efficiency of 93.3% at 26% moisture content at the sifting speed of 410rpm. Output Capacity of 136.2kg/hr was obtained and this increase as the Feed rate increases at 26% moisture content .Analysis of Variance for the Sifting Efficiency was computed and the result reveals that the speed and interaction of speed x federate and speed x federate x moisture content are significant at 5% probability. The machine is affordable and adequately manageable therefore recommended for the small scale Cassava Processor.
