Olive oil extraction should occur within an hour of crushing and malaxing. The ideal temperature for olive oil extraction is below 27 °C. This is also the temperature to keep this oil to maintain its quality. The extraction of the olive oil from the crushed and whipped olives occurs via horizontal centrifugation.
