Abstract :
A gas fired and automated garification
machine was developed and tested earliest to proffer
solution to the challenge of effectively controlling frying
temperature and agitators’ speed during garification. The
machine consistsof a control panel, 5.5Hp electric motor
(prime mover), pulley, v-belt, shafts, differential gears,
stainless steel metal pan, exit chute with cover, agitators
(paddles), spark electrode, gas burner, heating chamber,
electromagnetic gas shut off valve, temperature sensor,
timer, block bearings and frame. The lower and upper
frying temperatures and agitators’ speed limits for the
various stages in the process were achieved through the
panel while heat distribution was achieved by using a
radial gas burner and continuous agitation of the mash.
Effective garifiication was achieved at 65˚C and 98˚C
cooking and drying stages temperatures with a
corresponding agitating speeds of 20rpm and 40rpm
respectively. A 40kg mass of dehydrated cassava mash at
45%wb moisture level gave 30.40kg of fried gari at
12.17%wb after 15min of frying and consumed 1.87Kg
(0.062kg/kg of gari) of the cooking gas. The machine
accounted for throughput capacity and functional
efficiency of 121.66kg/h and 76% respectively. The study
indicates itsuser and gender friendliness and itis thus
recommended for adoption by cassava processors.
