This work focuses on the design of an electromechanical yam pounding machine. The machine consists of a shaft, electric motor, trough, propeller (yam beater), pulleys and the frame with vents for adequate cooling of the machine during operation. Mild steel material and stainless steel sheet were used in the design based on its availability, strength, appearance, cost, and corrosion resistance. The maximum volume of yam pounded was gotten to be 〖6000000mm〗^3 while a power requirement of 1hp was needed to drive the machine.However in this design, improvement was made on the overheating of the electric motor during operation by creating vents for adequate cooling, improvement on the size making it more portable than the existing ones and the use of dampers to minimize vibration with better reliability and working efficiency. From experiment carried out in using the machine to pound three different species of yam, it was observed that irrespective of the improvement done on reducing overheating during pound, it pounds in less time compared to the already existing ones.
