Abstract :
The conventional cassava peeling methods are
inefficient, time-consuming, and labor-intensive This
study aimed to create an enhanced cassava peeling
machine with minimal flesh loss. The machine design
includes components like a hopper, shafts, bearings, an
electric motor, and a v belt connected to a pulley that
drives the brush-equipped shaft. This locally sourced and
fabricated machine, designed for 50kg of cassava tubers,
was tested at operational speeds of 380, 420, and 460 rpm
and retention times of 4, 6, and 8 minutes, optimizing the
effects of machine speeds and peeling times on peeling
efficiency using I-optimal Response Surface
Experimental Design with a mean separation at P<0.05.
Results pertaining to tuber properties, such as angle of
repose, peel thickness, moisture content, peel penetration
force, bulk density, and coefficient of friction, were
utilized in the machine's design. The machine achieved
maximum peeling efficiency of 74% at a speed of 380m/s
when operated for 6 minutes. At this optimal efficiency,
the machine reached an optimal throughput capacity of
171.4kg/h, with a 21% flesh loss, a peeling weight
proportion of 25.8%, and minimal tuber damage (3.3%).
The desirability, which signifies the extent to which these
optimal values align with the optimization goal, was 0.83
(83%). In essence, this machine significantly advances
cassava peeling mechanization.
