Lack of groundnut processing machines at affordable cost, especially groundnut Sheller, is a major problem of groundnut production. Numbers of groundnut Sheller machines are available in the market but they are large in size, costly and not suitable for domestic applications, they are best suitable for industrial applications where mass production is required. Hence it is essential to design and fabricate a portable groundnut sheller machine for domestic application. This paper describes about the design of various components of groundnut Sheller machine. 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.
There are two methods of groundnut shelling. 1.1.1
Manual method
In Manual Shelling method groundnuts are shelled by hand simply. They are wrapped into the cloth and then rubbed onto the surface to decoct it. The cost for shelling is 5 to 6 Rupees per kg foe one person and also this is very time consuming process.
Key Words: Groundnut, peanut, shell, crushing, hopper.
1.INTRODUCTION Groundnut (Arachis hypogaea) is a species in the legume or beans family ([1], [2], [3]). It was first cultivated in Peru [9]. Its seed contains about 63% carbohydrate, 19% protein and 6.5% oil [1]. Groundnut is the sixth most important oilseed crop in the world. As the groundnut seed is contained in pod, which is usually developed underground, the pod is harvested by pulling or lifting the plant manually or by using the machine. The pods are stripped from the plant, dried, stored and processed. Shelling is a fundamental step in groundnut processing [1]. Shelling can generally be done by hand or machines. As well as the study of manufacturing was very important in order to carry out this project to ensure that what are needs to do. This project involves the process of designing the different parts of this shelling machine considering forces and ergonomic factor for people to use. This project is mainly about generating a new concept of groundnut shell (crush) that would make easier to bring anywhere and easier to crush groundnut. After the design has completed, it was transformed to its real product where the design is used for guideline.

Mechanized Shelling Method
In mechanization now we use large machinery for groundnut shelling. These machines are used in the industries where large production is required. They are having shelling capacity of 400 to 3300 kg/hr. But these machines are costly in order to purchase by the farmers.
