Name: Peanuts


Abstract: An experiment was conducted to study the process of using carbon dioxide to extract oil from peanuts in a production process.  The response variables were the amount of oil that could dissolve in the carbon dioxide (the solubility) and the total yield of oil per batch of peanuts. Each of the five factors was evaluated at a low (L) and high (H) level.


Variables (column):

  1. Carbon dioxide pressure (0=Low, 1=High)
  2. Carbon dioxide temperature (0=Low, 1=High)
  3. Peanut moisture (0=Low, 1=High)
  4. Carbon dioxide flow rate (0=Low, 1=High)
  5. Peanut particle size (0=Low, 1=High)
  6. Yield of peanut oil
  7. Amount of oil dissolved
