The highest rotation speed of the screw(R3) gave the highest hourly yields in terms of seed processing (48.2 kg/h), seed cake (34.4 kg/h) and gross oil (13.4 kg/h) recovery, but also very high levels of foots in the oil (10.5%), oil content in the seed cake (20.5%) and the lowest extraction efficiency R (62.4%).
The lowest rotation speed gave the exact opposite (R1)
