Abstract: Oats (Avena sativa) have been used both as food and feed for the last one thousand years. In oat grain, outer hull or husk, which is comprises 25-30% of the weight of the oat grain. Since, it is inedible and not digested by human beings so it should be removed from oats before processing. In India, there is no dehulling technology available for efficient dehulling and further processing of this grains. Based on this an indigenous oat dehuller based on centrifugal action because centrifugal action gave better performance for this grains to remove the resilient, inedible hulls as compared to dehulling with existing machines using abrasion principle. The performance evaluation of the machine was evaluated under three moisture content range (6 to 12 % wb.), impeller speed range (1900 to 2500 rpm) and feed rate range (75 to 225 kg/h) The results of an optimization technique revealed that the best dehulling performance was obtained if the system was operated at impeller speed of 2500 rpm and feed rate of 75 kg/h with moisture content of 6% wb. Under these conditions, the values of dehulling efficiency and percent of broken kernel were 70.42% and 3.64%, respectively.
