ing durum wheat requires more puriers whereas milling soft wheat requires more sifters with either less puri-ers or no puriers. 2. Flour renement required: higher degree of renement requires more compre- hensive owsheet with more puriers. 3. Flour end-use requirements. There are some important rules for owsheet design, which follow: 1. Fractions of material should not be routed back to the same machine passage or to preceding part of the system as it creates closed loop. 2. Rened our should be produced as soon as practically possible, and as soon as our stream is produced it should be routed to the our collection system.Otherwise the chance of contaminating the our is greater. 3. Generally speaking, once stock has been ground on pair of smooth rolls it should not be passed through pair of corrugated rolls. The owsheet of our mill (Fig. can be considered the blueprint of its milling process, and it is generally regarded as condential information by millers. This owsheet also shows various points in the diagram where our is extracted. Although, in general, these ours may appear to be similar, close visual examinationof all of their our streams would reveal visual differences in terms of color and, occasion-ally, ne specks of bran count. 3.3.9 Milling Performance Evaluation Flour sells at much higher price than bran; therefore, the measurement of our production is routine function in controlling the process. This important measurement of the perfor- mance is commonly referred to as the our extraction rate and is calculated as quantity of our produced as percentage of the wheat used. Variations of this calculation areapplied to provide such information as is critical to the operation over wider range ofsituations, as given in Table 8. The objective is to produce as much our as possible. However, the resultant our should be free of any bran and germ contamination. Although, our contaminated withbran can easily be distinguished visually, the evaluation o
