Abstract The nutrition layer separation milling method of feature wheat was investigated. In addition to wheat layered peeling and separating mill, the roller mill grading flour milling is the key factor of wheat processing. The optimal operating strategy for grinding effects and product quality was determined by pulverize roll surface treatment technology, feature selection and parameter configuration. The grinding effect of the grinding roller with increased vanadium or titanium elements was compared with that of traditional grinding roller. The results show that for the new grinding roller, the 1B single grinding roll stripping ratio is increased by an average of 1.92%, with decreased single roller average power consumption of 2.29 kW·h.The grinding material temperature is decreased by an average of 3.83 ℃with reduced flour yield of 0.87%. For 1M single roller with new formula, the flour extraction rate is increased by an average of 1.78%.The single roller power consumption is decreased by an average of 4.43 kW·h with reduced average temperature of 4.7 ℃.
