This study focuses on mechanized process of mixing and sieving variety of flour (such as yam, plantain, cassava, etc.) with ease and good finished quality, especially when large quantity is required. This is achieved by a combination of a channel fitted with a conveyor blade which is set in a spiral manner on a shaft to produce thorough mixing, and a net in a wooden frame driven by pulley and connecting rod to perform the sieving action. The designed machine is to be driven by a compound belt drive from an electric motor of 1h.p at 1400rpm and its throughput capacity is 13.4 kg/hour. The availability of both mixing and sieving compartment in the design has distinguished the machine from the regular sieving or mixing machine.  The machine is affordable and simple to maintain and therefore, it is recommended for small holders, local processors and home use.
