Abstrakt: In this study, hulling efficiency and hulling losses were optimised for pigeonpea. Effects of hulling time, moisture content and cottonseed oil as pre-milling agent were studied and optimised using response surface methodology. A quadratic model satisfactorily described the hulling efficiency with an R2 value of 0.93. It predicted maximum dehulling efficiency of 89.98% at 9.82% moisture content (wet basis), 12.05-s time of hulling and 0.28% cottonseed oil treatment. Linear model developed for hulling loss showed significant effect of time of hulling whereas effect of oil treatment and moisture content were non-significant. The model predicted hulling loss of 2.92% on optimum conditions. The results of the model were validated experimentally and were within the range. [ABSTRACT FROM AUTHOR]
