mechanism, the machine simplifies operation, reduces physical strain, and ensures efficient peeling. The compact and lightweight design, combined with the use of locally available raw materials, further enhances its affordability and adaptability. The primary objective of this project is to develop an innovative groundnut peeling solution that integrates mechanical efficiency, portability, and ease of use. The machine's design aims to bridge the gap between highend, motorized solutions and manual methods, thereby empowering farmers to optimize their post-harvest processes [2]. Through this research, we aim to contribute to the advancement of agricultural technologies that cater specifically to the needs of small-scale farmers and rural communities.
Groundnut Peeler Machine aims to provide a cost-effective, manually operated solution to meet the needs of small-scale farmers and businesses. Existing groundnut peeling machines are often expensive, reliant on electricity, and unsuitable for use in remote areas. This project introduces an innovative design incorporating a handwheel and Crank and Slotted Lever Mechanism, which effectively reduces human effort and minimizes operator fatigue.The machine features an adjustable peeling mechanism to accommodate various groundnut sizes, ensuring flexibility and efficiency across different varieties. Its compact and portable design makes it easy to transport, assemble, and use, providing an affordable alternative to traditional motorized peelers. The simplicity of the design also ensures low maintenance and accessibility for rural and small-scale operations.Future enhancements include integrating a chain and sprocket mechanism for smoother operation or motorization to further reduce manual effort. The machine can even be adapted as an exercise device, offering multifunctionality.
2. CONCEPT DEVELOPMENT Develop a conceptual design for a hand-operated groundnut peeling machine that includes a handwheel and a crank and slotted lever mechanism [3]. The design will emphasize simplicity, compactness and ease of use, making it ideal for small businesses and farmers. The machine will be easy to assemble and disassemble, allowing convenient transportation, storage and maintenance.

To accommodate different sized ground nuts, the peeling mechanism will be adjustable, ensuring optimum performance for different types of ground nuts. The design will also focus on reducing human effort and reducing unnecessary movements to avoid user fatigue, ensuring comfortable and efficient operation for long periods of time. Crank and Slotted Lever Quick Return Mechanism is mostly used in shaping machines, slotting machines and in rotary internal combustion engines [4]. Using this mechanism we can increase effective working time [5].
1. INTRODUCTION Groundnut peeling is a critical stage in post-harvest processing, particularly for small-scale farmers and rural communities. Efficient peeling not only impacts productivity but also determines the overall profitability of groundnut cultivation. However, existing peeling machines are often expensive, heavily reliant on electricity, and unsuitable for small-scale applications due to their bulky designs and operational complexity [1]. These limitations are particularly challenging for farmers in remote areas where access to electricity and high-end machinery is restricted. This study focuses on addressing these issues by designing and fabricating a manually operated groundnut peeler machine that is cost-effective, portable, and easy to operate. The proposed machine is specifically tailored to meet the needs of small-scale farmers, providing a practical solution that eliminates the dependency on electricity while improving productivity.
