Table 2 Comparison of the main factors affecting the efficiency of the
machine
Speed (rpm) Moisture content (% wb)
40 53.7a* 53.0 45.0e
60 52.4b 57.6 52.2f
80 47.9c 61.4 56.8g
*Means with the same letter are not significantly different at probability
level of 5 %
Among the speeds the highest (53.7 %) and lowest
(47.9 %) peeling efficiency belong to 40 and 80 rpm,
respectively. Also, among the moisture content the highest
(56.8 %) and lowest (45.0 %) mean peeling efficiency
values belong to 61.4 and 53.0 % w.b., respectively.
The results of mean comparison of interaction effects
of moisture content and machine speed on peeling
efficiency are shown in Fig. 3. The results showed that
in all moisture contents the peeling efficiency values
decreased significantly with increase in machine speed
