Basically the groundnut is grown by small scale farmers in developing countries like India. The average kernel price is approximately double the price of pod. Lack of groundnut processing machines, especially groundnut Sheller, is a major problem of groundnut production, especially in country like India. A research work for design, modeling and performance evaluation of groundnut Sheller consisting of fed hopper with a flow rate control device, shelling unit, separating unit and power system. The performance and output of the machine was evaluated in terms of throughput capacity, shelling efficiency, mechanical damage and material efficiency. Regression models that can be used to express the relationship existing in between the Sheller performance…show more content…
The design is an environment friendly and uses simple mechanical properties such as shelling system, blowering mechanism and automatic separating system etc. For this, some crushing force is needed to crush the groundnut. The design is done so that the knowledge and understanding of designing, mechanism and forces are increased. This project consists of designing and modeling of an groundnut Sheller machine considering various important and useful parameters. In this project, designing & development of a groundnut Sheller machine to crush or shell groundnut so the farmers can gain maximum profit by selling groundnut directly into the market. As well as the study of analysis is very important in order to carry out this project to ensure that what are the forces acts on different components. This project involves the designing and modeling of different parts of the shelling machine considering different parameters. This project is mainly about creating a new concept of groundnut shelling (crushing) that would make easier to bring anywhere and easier to crush groundnut. After the design will get completed, it is transformed for the analysis of different components of the…show more content…
Design calculations Determination of crushing power by analytical By, according to KICK’S RELATION Power required to shell the groundnut H = KK x Fc x In(L1/L2) Where, H - Power L1 - Length of shelled groundnut = 3.54 x 10-2 m L2 - length of unshelled groundnut = 1.48 x 10-2 m KK - kick’s constant = 1.2 Fc - crushing strength = 500 N/m2 C. Design Of V-Belt Design Power (Pd) = PR × kL Where,PR = rated power Load Factor, KL = 1.10 Selection of belt on the basis of design power. Nominal width, w Nominal thickness, t Recommended Diameter, D Centrifugal tension factor, KC Bending stress factor, Kb Peripheral Velocity, D1 = Diameter of smaller pulley i.e. electric motor shaft pulley, N1 = Speed of electric motor shaft pulley. If this velocity i.e. VP is in range then, Ok. Now, assuming Velocity Ratio, VR to calculate speed of driven
