【 摘 要 】

The designed Dehulling Machine is a machine used to removes shells from rubber seeds and as well separates the foreign materials from the rubber seed kernels. The Dehulling Machine for rubber seed processing is powered by Electric Motor, the Electric Motor drives the Shaft for dehulling operation and the blower/Fan Shaft, the Total Power required is 70KW. The Transmission System consists of arrangement of driven and driving Pulleys, Belt, and Shafts with Bearings. The diammeter of the driven and driving pulleys for the dehulling operation is 70 mm and 330 mm respectively and V-belt of 1.2 m long. The blower has driven and driving pulley diammeter of 63 mm and 130 mm respectively and V-belt of 761 mm long. The Dehulling Mechanisms include: Dehulling Shaft that accommodates the Dehulling Stone of diammeter 300 mm and thickness 80 mm. The Shaft is supported by bearing and the driven by driving pulley mounted on the eletric motor. The chaffs and the kernels collector is designed such that the kernels (heavier) fall freely while the chaffs and other foreign materials are blown off. The blower has fan duty of 1 m3/s and made of the blades Support (length = 20 mm, breath = 10 mm, thickness = 10 mm, no = 12), Blade (length =100 mm, breath = 60 mm, thickness = 0.5 mm, no of blade = 6) and Blower Cylinder. The main frame is made of mild-steel and it accommodates all other members of the machine.
