Laboratory oven were used for drying samples have been study.
Initial seed moisture comtent was 24% w.b.
Digital moisture content (model GMK-303)
is used for determing grain moisture content.
In this study were analyzed using completely randomized design with factorial experiment and to compare the means of main effects and interaction effects was used the duncans multiple range test was used. Milling of samples was performed by rubber roller huller and laboratory abrasive whiteing. Results of the data analysis showed that variety of Hasani (with average of 14.25%) had the minimum skinning waste among three mentioned varieties. Increasing of drying temperature (from 33 to 53˚c) increased average hulling waste significantly from 14.100 to 20.926%. On the other hand, increasing of moisture content of grain (from 8 to 16% w.b.) decreased significantly mean hulling waste from 22.016 to 14.605%. Moreover, in this study was determined that variety of Ali Kazemi had the minimum whiteing waste among three mentioned varieties. Increasing the ultimate moisture content of kernel and drying temperature affected significantly whiteing waste.With increasing drying temperature and reducing the final moisture content of grain amount of waste resulting from the mill in whiteing at significantly increased.
