ThesisItem Open Access DEVELOPMENT OF PEDAL OPERATED GROUNDNUT DECORTICATOR(Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.), 2020) Das, Arun; Jogdand, S.V.; Victor, V.M.; Agrawal, Sunil; Pradhan, M.K.; Pisalkar, P.S.Groundnut is the sixth major important oilseed crop in the whole world and it is cultivated by farmers in Chhattisgarh. It is a rich source of nutritional fiber, minerals and vitamins. Decortication is the removal of the groundnut kernel from groundnut pod. There are various methods of groundnut decortication of varying capacity. Farmers of Chhattisgarh are still using the traditional method to decorticate the groundnut pod that causes injury on palm hand, tiredness of finger. Groundnut decortication is a time-consuming and tedious process. This process gives less output and requires high efforts by the user and eventually higher energy input. Today, many of the commercially available decorticator which are operated by hand, fall in this category. Therefore it was conceived to develop such a machine which will require less effort with less energy consumption. To develop various parts of the groundnut decorticator various physical parameters of groundnut pods handsets were studied. Overall dimension of main frame are 1760 mm x 803 mm x 1100 mm. The performance evaluation of pedal operated groundnut decorticator was evaluated by different treatment combination of clearances and moisture contents. Different clearances between rotating drum and rubbing plate. i.e. 8 mm, 10 mm and 12 mm and different moisture contents of ground nut pod i.e. 6.53%, 7.85% and 9.23% dry basis were observed. The Decorticating capacity, output capacity, decorticating efficiency, unshelled pod and kernel broken were 92.41 kg/h, 51.95 kg kernels/h, 86.37 %, 13.62% and 15.65% respectively at the best optimum combination of clearance and moisture content of 10 mm and 6.53 % respectively were found. The total cost charged for the development of per unit pedal operated groundnut decorticator was ₹ 14000 and the operational cost is 90.43 ₹/h including fixed and variable cost. The cost required to decorticate 1 kg of groundnut pod was found ₹ 0.97. The developed pedal operated groundnut decorticator is reliable and satisfactory for the selected variety of groundnut. An attempt has been made to develop a pedal operated groundnut decorticator. It was revealed from the study of literature available that the pedal-operated decorticator provides better performance than a hand-operated decorticator.
