An extraction efficiency of 80% is considered very good. Most large commercial operations use a mild pressing operation to extract 60 to 70% of the oil, while the remainder is solvent-extracted. The advantages of pure mechanical extraction are lower initial investment costs, higher-value edible oil and meal, and a safer and less complex operation.
