y different types of grain- and seed- cleaning operations. They are available in many different makes and designs. The basic equipment consists of two shaking screens. The top screen, with larger perforations than the wheat size, removes larger impurities while allowing wheat kernels to drop through.Wheat kernels along with ner impurities are then spread on the bottom screen, whichhas ner perforations than the wheat size, allowing only ner impurities to pass throughthe screen and be removed separately. Wheat kernels, thus, tail over the bottom screen Grain-Milling Operations 2 Table 2 Cleaning Equipment, Principles of Separation, and Impurities Removed Properties Types of foreign material Equipment in use Size Larger Unhulled kernels, corn, soybean Grain separators, scalperator, and as well as any material larger any other machines that use than the wheat size. screens or sieves for separation.

One such aspiration channel with an air-recycling feature will be de-scribed later. modern separator classier is shown in Fig. 7. This machine can be used for variety of grain, coffee bean, and cocoa bean cleaning and grading operations. This is h
