The work highlights the analysis of the influence of technological and structural parameters of the screw press, namely the step of the turns of the screw shaft of its speed and the area of openings for the removal of cake on the energy parameters of the process of oil expression.  Based on the results of the multifactorial experiment, regression dependence allows us to estimate the influence of the parameters and operating modes of the screw press on the power consumption of the screw press and can be used in the process of synthesis and modeling of machines intended for pressing of vegetable oils from oil-containing raw materials. The surfaces of the response of the dependence of the power consumption of the screw press from the area of the openings for the removal of the cake as well as the step of the turns and the speed of the screw shaft have been constructed.  Providing the following parameters of the pressing process: turn pitch of the auger shaft X 10  = 21.8 mm; area of openings for oil cake withdrawal X 20  = 107.99 mm 2 ; rotation frequency of the auger shaft X 30  = 5.12 min  -1 , the power consumption of the screw press will be 170 W, ensuring the maximum yield of oil q = 36%.
