Description
Abstract
This engineering project focuses on the Design and fabrication of groundnut shelling machine. Groundnut shelling machine was designed and fabricated at the Department of Mechanical Engineering, Institute of Technology, Kwara State Polytechnic Ilorin aimed at increasing shelling/decorticating efficiency and eliminating drudgery associated with the traditional method of -shelling groundnut and other developed methods such as pedal-operated methods. The machine is powered by a 1.5 horsepower motor at a speed of 1440 revolution per minute. Performance investigation carried out show a good performance of the machine with decorticating efficiency, undecorticating efficiency, machine damage efficiency, cleaning efficiency and output capacity of 92%, 7.5°k, 3%, 85% and 120kg/hour respectively. It is recommended that a motorized oscillating decorticator for commercial production for human and even animal consumption be fabricated using stainless steel material for critical parts.
