57 COVER STORY MILLER / may 2021 Milling performance simply means the run- ning efficiency of the milling and cleaning machines at optimum capacity. In other words, it means consistency in the opera- tion of the milling equipment and production activities without downtime or breakdown of equipment and maximum utilization of the milling machines' capacity. Wheat milling aims to separate structural components of the wheat kernel by break open the grain and recover the endosperm from other parts which are the bran skins and embryo and then reduce the endosperm to particles with a specified size distribution. Millers make their efforts to have three major objectives, which are the optimum ex- traction rate with the maximum quality of finished products and the capacity of the mill. Their efforts for these objec- tives are aimed to have the optimum economic balance of these objectives. Miller to achieve his aim has to practice efficient milling techniques and optimize the streams of ev- ery machine in the mill. So intermediate streams are con- tinuously monitored for quantity, quality and granulation and this data is used for adjustment by the miller. Optimum milling performance refers to items such as output per hour, extraction, quality of final flour such as color, water absorption, protein values and moisture con- trol with regard to milling gain or loss. Increasing performance by the technology of the mill- ing system basically depends on raw materials, process- ing conditions, process control, processing parameters, monitoring and diagnosis, energy management, correct equipment, trained person, operator, engineering, quality control, correct design, technology level and yield.
