In this study, we focused on the design and fabrication of a yam pounding machine that performs the hygienic processing of pounded yam, eliminates the laborious process involved in pounding yam and to minimize the time for processing pounded yam. The machine was fabricated using mild steel, stainless steel, pulleys, belt and shaft. A type A43 belt was used (V-belt), the depth of the bowl is 425mm, length, width and thickness of the beater is 148 x 51 x 16 mm. The diameter of the driving pulley is 70mm and the diameter of the driven pulley is 210mm. The length and breathe of 650mm by 760mm. The result from the testing showed that the yam pounding machine produced a hygienic and well processed pounded yam in a lesser time. It totally eliminated the laborious involved in pounding. The efficiency of the machine was 88.171%N which is fair for a locally fabricated machine. Given that some percentage was lost due to the vibration from the motor.
