P15482: Breadfruit Shredder and Grinder Group Members: Andrew Beckmann, Patrick Connolly, Brittany Griffin, Samantha Huselstein, Alan Kryszak

Agenda ●Project Background ●Problem Statement and Deliverables ●Use Scenarios ●Customer Requirements ●Engineering Requirements ●Project Plan ●Project Risks

Project Background ●Haitian life ●Transportation ●Plentiful fruit in Haiti o Highly wasted o Highly nutritious

●Breadfruit needs to be preserved to make the season more profitable. ●The goals of this project are to create a breadfruit processor that will result in a consistent quality flour. ●The project deliverables will be a working prototype to shred and grind breadfruit effectively. Problem Statement and Project Deliverables

Current State of Project ●Benchmarking o Devices built by MET students  Broke processing into 5 steps o Food processors o Flour mill o Grater

Stakeholders ●Farmers in Haiti o KGPB ●Sarah Brownell o NPO ●Possible Investors ●Haitian Market ●Other 3rd world Farmers

Project Plan

Risks and Concerns ●Finding a reliable breadfruit vendor (Spring and possibly Fall) ●Receiving parts on time to meet project deliverables ●Dryer MSD team missing deadline/requirements needed to proceed ●Finding locally available materials to use for the shredder/grinder mechanisms ●Making a product durable enough for high usage. ●Reliability of product in a harsh environment (rain, dust, etc) ●Risk of injury due to blades/sharp edges on shredder ●Risk of injury due to blades/grinders in the grinder ●Risk of injury from exposed gears or mechanisms ●Risk of injury from hand/finger entrapment in shredder or grinder
