Design and Fabrication of Groundnut Shelling and Separating Machine

Abstract

This work focused on the design and fabrication of a groundnut shelling and separating machine electrically powered by a 1hp motor. The machine has the capacity of shelling 400kg of groundnut per hour with a shelling and separating efficiencies of 95.25% and 91.67% respectively. The machine was fabricated from locally sourced materials, which makes it cheap and easily affordable and also easy and cheaper to maintain. It is also of light weight and comprises of the hopper, crushing chamber, separation chamber and the blower unit. During the process of testing, it was observedthat majority of the groundnut pods that came out unshelled or partially shelled were the oneswith one seed per pod and those with two small seeds in their pods
