India is one of the world’s largest country in terms of exportingers of cashews nuts in kernel form. Currently, more number of labours are engaged in the cashew processing industry. This research work, an automotive cashew shelling method is introduced to improve the production efficiency. It is an electronic based system which enables a continuous flow of shelless. After de-shelling the cashew nut, it falls beneath the cutter due to gravitational force and shelless cashew nuts cumulated in a vessel. Thus the proposed system has the advantage of reducing man power, time consuming and also increases the selling cost. It comprises two process. They are heating and punching process. Both processes are used to remove the cashew kernel from the shell without damage. Here a servo motor is used to extract the shell from the raw cashew. In addition, here PI controller is used to control the entire operation. Then, two blades are used to cleft the nut by operating as handle of cutter. Thus the operation forces the shell to fracture open without detaching the kernel.
