The dehulling characteristics of different pulsesare given subsequently in Table 8. 4.1 Denitions of Dehulling Efciency The dehulling efciency is dened by two expressions, dehulling effectiveness and quality of dehulling (: hulling/H1/H2/H1n1 n2/H2( where Ehulling/H1effectiveness of dehulling n1,n2/H1mass of unhulled grains after and before hulling The quality of dehulling is dened as Ewk/H1k2/H1k1 (k2/H1k/H1(d2/H1d/H1(m2/H1m( where Ewk/H1quality of dehulling k1,k2/H1mass of whole split kernels before and after hulling d1,d2/H1mass of crushed kernels before and after hulling m1,m2/H1mass of mealy waste before and after hulling The overall dehulling efciency ( ) is then dened by Eq.
