Pea (Pisum sativum L.) is a multipurpose leguminous crop that can provide food and fodder for the small-scale farmer in subsistence agriculture. It is also known as ‘Dry Pea’ and it is called as ‘Matar’ in India. India is one of the largest producers of field pea in the world and stands at the 5th place in the list of major field pea producers. In India peas are mainly grown in Uttar Pradesh, Madhya Pradesh, Himachal Pradesh and Jharkhand. Pea is widely cultivated and processed in India predominantly done manually. India is also producer of pea but there is lack of machine for shelling of pea. Due to lack of this specialized technology and equipment for shelling of pea an effort have been made to develop a low cost green pea depoding machine which was designed and developed in the workshop at the department of Agricultural Process Engineering, SHIATS, Allahabad. The present study on designed and development of green pea depoding machine includes motor, frame, roller, sprocket, pulleys, belts, adjusting screw, tray vibrator shaft, plates and feeding tray. The machine was powered with a 0.5 hp motor with help of suitable mechanisms. The machine has overall length of 1015 mm, a height of 880 mm and a width of 400 mm. Three different types of pulleys were made attached on machine i.e. Transmission pulley which helps to rotate roller, smaller pulley lifts the tray in upward and downward motion and motor pulley for transmitting the power to the transmission pulley. An adjusting screw is provided in machine for adjustment of rollers to maintain clearance for shelling of green pea. A tray vibrator shaft is provided for passing peas towards roller. Two types of plates were also provided in machine for passage of pods and kernels. Results of the developed depoding machine showed mean values of depoding capacity, damage percentage and undepod percentage as 14.88 kg/h, 6.53 % and 7.52 %, respectively; while, the depoding efficiency was 93.53 %. The estimated cost of the machine was Rs. 20000 and the cost of operation was found 37.43 Rs/h. The overall weight of the whole machine was 45 kg which was easy to operate and individuals or user can easily handle it. Overall performance of the depoding machine was found quite satisfactory.
