r choice. The reciprocating at screen cleaner has three screens and one dust (suction) fan. The foreign material, including dirt, dust, and such, is separated, and the pulse is gradedfor milling purposes. stroke of 3 mm is provided for the reciprocating unit. Details of size, capacity, and other specications are shown in Table 5. The functions of various cleaning and grading equipment for pulses are described in the following (. Scalpers are used to remove large unwanted trash and nes. The separation is done on reciprocating or rotating screens. Air-screen machines are used as scalpers for size separation as well as weight separation. The material is aspirated to remove light materials, then passed overscreens to remove large materials as overs. The unders are passed on secondscreen to separate nes from desired size seeds. Disk and cylinder separators consist of series of cast iron disks mounted on shaft revolving at very precise speed relative to disk diameter within cylindri-cal housing. The disks have precise undercut pockets with size and shape varia- tions which allow the smaller seeds to be lifted and to reject larger seeds. Indent cylinders are machines of choice for length separation. They are almost horizontal rotating cylinders lined with hemispherical depressions. Short seedsare picked up in the indent and lifted up and thrown into an auger to be carriedout of the rotating cylinder. Width and thickness separators are typically rotating, cylindrical, perforated shells. Larger seeds will not pass through and discharge from the end of the cyl- inder. Gravity separators separate seeds based on combination of shape, size, specic gravity, and surface characteristics. The seed mixture is fed onto an oscillatingdeck with carefully controlled air movement to uidize the material. The mixtureis stratiedlighter up and heavier down; the seed layers along the deck in differ- ent directions toward discharge ends. Spiral separators work on the basis of the shape
