Design, Development and Performance Evaluation of Groundnut Pod Stripper

Abstract

This project only removes the pods from their roots so the farmers can work easy and can save time and money as well. It is very efficient and can be available to all at minimum cost. This work focused on the design and fabrication of a groundnut pod striper machine electrically powered by a 1hp motor. The main components of the developed stripper are stripping cylinder, frame cover to protect the pods from scattering and sieve for cleaning purpose. According to the design dimension the conceptual drawing was built with the help of SOLIDWORKS software. The principle of the designing is based on the horizontal circular rotary motion. The developed pod stripper has a dimension of 1170 × 930 × 560. The performance of the developed pod stripper was tested with three independent parameter i.e. feed rate (kg/h), moisture content (% db) and cylinder speed (m/min) and the dependent parameters were stripping efficiency, cleaning efficiency and damage percentage. It was found that the stripping efficiency is 97% and stripping capacity is 195 kg/h, cleaning efficiency is 87% efficient. There were no losses but the scattering of groundnut pod was 0.83%. The developed machine have output of 10 times more than the traditional method with profit of more than 10 times.
