ABSTRACT

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 method such as pedal operated methods. The machine is powered by a 1.5 horse power 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.
