Among the moisture content the highest mean value of
the peeling efficiency (60.3 %) was recorded for moisture
content 61.4 % wb at machine speed of 40 rpm.
The peeling capacity of the machine was found to be
40.5 Kgh−1.
Conclusions
A prototype device for peeling kolanut was developed
and evaluated in this study. The results of the test
showed that the moisture content of the fruits and speed
of operation of the machine significantly affect the peeling
efficiency of the kolanut. The peeling machine works
more efficiently as the moisture content of the fruit
increases with a very low speed of the machine. The
performance evaluation showed that the efficiency of the
machine was significantly affected by moisture content
and speed of operation of the machine. The highest
efficiency of the machine was 60.3 % at a moisture
content 61.4 % w.b and speed of 40 rpm.
