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 wastedo 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

● Benchmarkingo Devices built by MET students

Broke processing into 5 stepso Food processorso Flour millo Grater

Stakeholders

● Farmers in Haitio KGPB

● Sarah Brownello 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
