1. Peanut Oil Press Oil Extraction Development

2. Market Research  Over 100 peanut producing countries  African Tribes 5,423,000 gal. used in Africa 2000  Increase is est. 994,620 gal. to 2001 Consumer Needs  “Off Grid” energy source  Easily Repairable, Robust  Continuous  Increase Production Rate Peanut Producing Developing Countries Photo: Amy Smith

3. Market Data

4. Peanut Crush Experiment Leakage Problem: O-Ring Solution Oil and Solid Separation Absorption

5. Water Experiment Water Separation Theory  Density Water > Density Oil Compress peanuts in water  Peanut Oil dissolves – cloudy solution  Time reduction for separation?

6. CAD Model of Piston Arbor Piston Peanut Chamber Solids Oil

7. Sketch Model Design Attributes  Continuous Process  Ease of Cleaning, Oil/Solid separation  Eased Labor  Increased Production Speed

8. Technical Data Power = 14 Watts Force on Peanuts = 17237 Newtons Pressure = 1000 psi  300 psi starts to develop oil Production Speed = 6 liters/hour  1liter/hour Pressure Mechanical Advantage =100:1 gear ratio

9. Next Steps Material Selection for Safety  Safety Factors, High Pressure resistance Mechanical Design  Anchoring (for safety)  Oil/Solid separation (max output)  Oil Leakage Power Selection  Ratchet, Seesaw, Rowing, Pulleys, Lever
