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.

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0Â Â Â INTRODUCTIONYam is another crop cultivated across Nigeria. It is a seasonal crop and very difficult to preserve as it tends to rot. Nearly all Nigerians consume yam on regular basis and in large quantities particularly the Yoruba tribe in Nigeria. Nature allows yam to form a bond when it pounded or beaten in a mortar, it is then consumed as a meal with a choice soup. Pounded yam is a staple food consumed by the indigenous process of pounding yam is very laborious. It require ... Continue reading---

CHAPTER THREE - [ Total Page(s): 9 ]Hence, the belt was selected for the pulley as calculated above.3.2   DESIGN CALCULATIONThis refers to some characteristics which affects or influence the design of the machine or perhaps some of the components. However, out of the numerous factors that affected the design, only one or few will turn out to be the major factors and the minors ignored as they would have little or no effect in the design. These factors or characteristics are:•   Thermal conductivity of the materialââ ... Continue reading---
CHAPTER FOUR - [ Total Page(s): 3 ]4.2.2 POUNDING EFFICIENCYThere is the need for careful consideration of the traditional way of yam pounding, time and the manpower required in carrying out the operation. If it takes a minimum of 1-2hours to pound about 20kg of yam manually coupled with its unhygienic mode of operation, then it will take about 15minutes to pound the same quantity of yam with greater output and greater quality.Hence, the general productivity per hour for the machine can be calculated thus:In 15minutes, 20kg of ya ...
