This study was focused on the analysis of optimize the pressing process of rapeseeds ( B rassica napus L.) using screw press. For pressing of oil a screw press Farmer 20 – duo (Farmer 20, Farmet a.s., Ceska Skalice, Czech republic) was used. The screw rotation speed 10, 20, 30, 40, 55 and 65 rpm was used. Oil recovery efficiency and specific mechanical energy were decreased when the seed material troughput was increased. It has been found that the optimal operation point for screw press Farmer 20 – duo was at 20 kg h - 1 rapeseed throughput. The specific mechanical energy at the optimal operation point was 0.61 kWh kg oil - 1 Maximum oil recovery efficiency 82.6% was found at the lowest screw speed.
