ABSTRACT
The aim of this research work is based on the design and development of a motorized yam pounder for pounding yam. This research was considered because of the importance of pounded yam in Africa particularly in Nigerian and because of the time and energy wasted using the traditional mortal and pestle method of yam pounding. The research work aimed at eliminating the labour involved in traditional method of pounding. Through this improvement, the possibility of food contaminating by sweating while pounding will be control. This project work sought to design a yam pounder that pounds yam right from the peeled cooked stage in a pounding bowl with the help of an electric motor that transmit power through rotary motion together with the help of shaft. The pounding blades function at the pestle. The machine is to be operated by electricity and it consists of shaft, electric motor, yam beaters or pounding blades, bowl and the frame. Metal Rod for shaft; 0.30mm, Angle Bar for Frame; 40O, Stainless Steel Sheet; 0.2mm, Flat Mild (Pan); 2mm (Thickness), Prime mover; 1horse power, Bolts and Nuts; M8, Belt; V-belt, V-35, Screws; Cap Screw. Low cost materials were used so as to make the machine affordable for average. Nigerian homes, thereby improving the standard of living. In order to avoid food contamination stainless material were also incorporated for smooth and clean pounding before consumption.
