In India, most land is used for agricultural purposes which produces semi- finished products or goods. Groundnut is also one of the agricultural semi- finished goods. Groundnut is grown on small scale farmers in developing countries like India. The average kernel price is approximately twice the price of pod. . Lack of groundnut processing machines, especially groundnut Sheller, is a major problem of groundnut production, especially in our country India. In the beginning the peanuts were separated from its shells by the workers. They simply decoct the groundnut by their hands and separate the peanuts from its shell. The output from this method was very low and it does not fulfill the market demand because it was a very timeconsuming process. Regression models that could be used to express the relationship existing between the Sheller performance indices, pod moisture content and feed rate were established. This paper describes the design and fabrication of various components of groundnut Sheller machines. Hence in this design of various parts are necessary, and design of various parts due to which the design quality of those parts will be improved. Overall, this project involves processes like design, fabrication and assembling of different components etc.
