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.
