Abstract

This study focuses on the development of a manually operated tiger nut crusher, designed to address the challenges faced in Nigeria due to high fuel costs and unreliable power supply. Tiger nuts, known for their nutritional value and health benefits, have varied uses in food and cosmetic industries but face post-harvest losses and processing inefficiencies. The project encompasses market research, conceptual design, material selection in compliance with safety and food contact regulations, and detailed design considerations to ensure safety, ease of operation, and cost-effectiveness. The crusher aims to facilitate small-scale processing of tiger nuts into milk, flour, and other products, preserving their nutritional content while offering a sustainable alternative to mechanical processing methods.
