Team Vision for Problem Definition Phase
- Our team planned on completing all of the assigned deliverables within the problem definition and gaining a better understanding of our scope of work.
- After interviewing Dr. Stevens and Sarah Brownell, we completed our deliverables to the best of our abilities as we refined our scope of work.
Project SummaryHaitian farmers in the Cooperative KGPB (Konfederasyon Gwoupman Peyizan Bòy) in Bornge, Haiti are looking to reduce waste of spoiled crops and increase profits with their fruit harvests. During the harvest season, the markets are flooded with breadfruit, mangoes, and other tropical fruit that drives down prices and leads to significant waste, because viable preservation technology is not available in rural areas. Drying is proposed as a method to preserve these fruits in areas like Haiti, where sun is abundant but conventional fuel resources are scarce. The scope of this project is to develop a functional crop dryer out of inexpensive materials that are also accessible in Haiti which will dry bulk sizes of fruit at a time. The project consists of developing crop dryer concepts, collecting data and testing results in a MatLab model, developing a design, and carrying the design through assembly and test.

Use CasesConsumer Perspective
- It gives them the ability to have a long lasting supply of fruit that can be eaten in between growing seasons when there is little no fruit on the market.
- This extended shelf life also provides a business opportunity for farmers. If stored properly, dried fruit takes several months to spoil so farmers can continue to sell their produce in between growing seasons.
- Having a supply of dried fruit can also act as a fail safe to serious injury for farmers. They can continue providing for themselves even though they are unable to harvest their crops.
Project Goals and Key Deliverables
- A functional prototype that will be used to dry a reasonable amount of fruit in a short amount of time (<2 days).
- The device will be constructed out of materials available in Haiti.
- The device will be built to withstand rural Haitian environmental conditions.
- Documented design, testing, and construction of the device to aid in the manufacturing of the finalized prototype.
- Construction and maintenance instructions for the finalized prototype.
