small portion of it is additionally extracted as granular rened product referred to as semolinaor farina. These are considered the main products of our mill. There is small portionof endosperm that becomes highly contaminated with bran during the milling process and 3 Sarkar Fig. 3 Finished our and by-products storage, handling, bagging, and bulk loading. (Courtesy of Bu hler, Inc.) thus cannot be recovered. This material, commonly referred to as middlings in North America, along with bran, shorts, and germ form the by-products of the milling industry. 3.6.1 Bran Bran, as described earlier in the milling process, is removed from the break system. After cleaning up and sifting in the last break passage, the coarsest material that is removed isthe bran. The next coarsest material removed in the same passage following the removalof the bran is the ne bran or shorts which will be described next. Bran from the sifter is sent to the bran duster for nal clean up before being sent to the storage bin. Bran is sold in bags or bulk, and sometimes it is pelletized. Bran has very low bulk density; therefore, converting it into pellets reduces its volume substantially. This isparticularly benecial when bran has to be transported over long distance. The crudeprotein and ber levels are high in bran, making it particularly suitable for animal feedration. Some bran is also used for human consumption, such as in whole wheat breads, bran mufns, and breakfast cereals. 3.6.1.1 Shorts Shorts is also passed through shorts duster after it is removed in the break system. It essentially consists of relatively ner pieces of bran particles. Its main application would Grain-Milling Operations 3 be in poultry rations. In small plants, middlings are sometimes mixed with shorts and marketed as one product. Clean shorts without any middlings in it, may also be blended with our directly on line for the production of whole wheat our. 3.6.1.2 Middlings Middlings are the brous residual branny or e
