of the seed to roll at different rates. The angle of the ights of the spiral has to be adjusted based on the typeof crop. Color sorters have proved to be very effective but need considerable adjustment, capital investment, and are slow, although it is expected that improvements inspeed will be made. Pulse cleaning can be accomplished by an air screen machine with the addition of spiral, gravity separator, destoner, and perhaps color sorter. The indent cylinder can helpfor lentils. Cylinders for width and thickness separation should be used with care, becausethese machines tend to damage lentils. These machines are also seldom used for peas.Gravity tables are commonly used for lentils and some times for peas. Such tables arevery useful for difcult separations. Disk and cylinder separation is seldom used for peas. 3.2 Seed Conditioning to Promote Dehulling Conditioning is general term applied to heating, cooling, wetting, drying, or any combi- nation of these processes. The effects of conditioning on the seed could be to toughen 4 Sokhansanj and Patil the hull (bran), loosen the bond between the hull and the cotyledon, crack the seed coat, and harden the cotyledon to resist damage. In review of food legume processing, it was reported that in developing countries, whole grains are soaked in water for short time before pounding in mortar and pestlefashion to remove the hulls (. Heat treatment of moistened grains, or in some dry grains, makes the hull easier to remove as it becomes brittle and cracks. Also, the cotyledons tend to shrink more than the hull during this process, resulting in the hull being loosened fromthe cotyledon. Addition of moisture softens the grains and make them susceptible toscouring; whereas drying hardens the grains and increases their resistance to scouring.Pigeon peas are dried from typical moisture content of 1 to 6% to provide increasedresistance to peripheral scouring. The tempering of small lentils before dehulling has been investig
