Development of a Pedal Powered Garri Frying Machine

Abstract

This study was aimed at developing a pedal powered garri frying
machine key design criteria were considered using a decision matrix.
The bowl type garri frying machine which had the highest grading
based on the criteria considered was selected for production. The
design parameters considered were heat required for garri frying,
load bearing capacity and structural strength of pedal mechanism,
effort required pedaling the bicycle, length of the chain, shaft and
frame design, design of key and bearing selection. The fabricated
garri frying machine was assembled and tested using measured loads
of wet garri mash. Five different frying trials were carried out with
the machine manned by various individuals of given grades and
gender distribution. The result of the performance evaluation of the
fabricated machine showed that there was a reduced involvement of
human effort in the frying of garri which reduced fatigue and
discomfort, and the use of motorized stirrer enhanced more
uniformity in the grain dynamics and heat propagation which
enhanced garrification during frying.
