The study is devoted to increasing the reliability and durability of the pressing chamber of the screw press for processing oilseeds by creating a method of calculating the strength of the pressing chamber as a shell with circular and longitudinal supports. The values of the pressure in the pressing chamber during pre-press and expeller expression are obtained. At forpress pressing the pressure in the zeer chamber reaches 100-200 kg/cm² , and at expeller pressing 200-300 kg/cm² . The method for calculating the stability of reinforced shells together with the theoretical calculation of the effective, actual degree of compression on the turns of the press depending on the seed culture is developed.
