    Expeller pressing - Wikipedia

    Afterward, the pressed seeds are formed into a hardened cake, which is removed from the machine. Pressure involved in expeller pressing creates heat in the range of 140–210 °F (60–99 °C). Raw materials are typically heated up to 250 °F (121 °C) to make the pressing more efficient, otherwise the pressing itself will heat the oil to 185–200 °F (85–93 °C).
