Correlation analysis of grinding roller surface treatment and grinding characteristics of wheat processing

研究特色小麦营养层分离制粉方法,除小麦分层脱皮分离制粉外,辊式磨粉机分层碾磨制粉是特色小麦加工的关键环节,磨粉机磨辊表面的技术处理、特性选择和参数配置是影响制粉工艺效果和产品质量的关键.通过对磨辊表面材料配方增加钒钛元素的磨辊与传统配方磨辊进行研磨效果对比,结果表明:采用新配方浇铸的磨辊1B磨单辊剥刮率平均提高1.92%,单辊动力消耗平均降低2.29kW·h,磨下物料温度平均降低3.83℃,皮磨单辊出粉率降低0.87%;1M磨采用新配方浇铸的磨辊单辊取粉率平均提高1.78%,单辊动力消耗平均降低4.43 kW·h,单辊磨下温度平均降低4.7℃.

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 ℃.
