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

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

CAD Model of Piston Arbor Piston Peanut Chamber Solids Oil

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

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

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
