Tables 1 and 2 show the results of the performance tests
analyses. Table 1 shows that moisture content (M), number
of impeller slots (f) and impeller slot angulations (S) significantly
affect the shelling efficiency (S ), percentage of
broken seeds (b ), percentage of partially shelled pods ( p ),
percentage of unshelled pods (u ) and winnowing efficiency
(w) at the significance level of 5%. The interaction
between moisture content and number of impeller slots (Mxf)
has a significant effect on the shelling efficiency and the percentage
of partially shelled pods at the significance level of
5%, while the interaction between moisture content and impeller
slots angulations (MxS) significantly affects the shelling
efficiency, the percentage of partially shelled pods and
the winnowing efficiency at the significance level of 5%.
