Design and Fabrication of a 1.4kg/hr Dry Groundnut Peeling Machine

Abstract

The design and fabrication of a 1.4kg/hr dry-groundnut peeling machine
using locally sourced materials is presented in this paper. The design of
the machine shaft, power of electric motor, total volume occupied by
seeds and the maximum number of seeds in the cylindrical peeler barrel
were carried out. 257 dry groundnut seeds were prepared and tested on
the modified machine, measuring the mass of seeds to be peeled and
unpeeled, testing for peeling effectiveness, peeling rate and groundnut
material loss from peeling. A graph of the peeling efficiency was plotted
against the number of seeds fed into the machine. Results showed that,
the peeling machine has an average peeling efficiency of 83.04% and
unpeeled efficiency of 16.96%.
