Garri Processing Machine Sustainability Track Team: Alissa Albert (IE) & Anne Froustet (IE): Cost analysis, Benchmarking/Initial testing Coleman Glasgow (ME) & Joey Lawson (ME): Mechanical analysis (including stress/fatigue calculations) Guide: Dr. Taylor Sponsor: Mechanical Engineering department

Project Overview Garri is a staple food of West Africa made from the cassava root Production is time consuming and labor intensive Design a machine to improve upon current processing methods Project intended to benefit lower class Nigerian families Project propsed by rit alum and west african native Eze Kamanu Our target customer is lower class families, making up approximately 30% of the Nigerian population. Initial production targets 10% of lower class

Quarter Review Redefine Objectives Concept Development and Revision Feasibility Analysis Define customer and processes to focus on Concept Development - Brainstorming, benchmarking, Concept review, revised design to meet budget and time constraints Feasibility analysis included testing of commercially available products - by peeling yams, time trials etc

Final Design

Final Design

MSD II: Project Plan Acquire materials and components Machine and assemble grater base and peeler support Sand casting Testing Learn sand casting process Create an artifact for production via sandcasting Initial Testing Modify components based on results of tests Final testing and tweaking of prototype Prep for final demonstrations and feasibility, presentation - work on paper, web, poster etc

Test Plan Critical Areas Cycle Time % Waste Required Re-work What and how (if asked about fatigue - structure designed for infinite life (1 million cycles) Blades require sharpening or replacement, supply 2 extra blades, grater must be purchased How: peel yucca
