Introduced an oil press for the production of environmentally friendly butter. A research methodology for substantiating optimal parameters is presented. Based on the theory of probability and mathematical statistics, the regression equation describing the complexity of the production of environmentally friendly butter was determined. When solving it, the optimal design and kinematic parameters of the oil press. Its optimal parameters were established, which were: the value of the angular velocity of the screw 6.3 s-1, the change in the pitch of the screw winding in the zones of 17.7 mm and the utilization factor of the throughput of the loading zone of the screw 0.6. At the same time, the technological labor intensity of the oil press per cycle was 18.385 man-hours. Research in production conditions has confirmed the correctness of finding the optimal values for the parameters of the oil press. The resulting technological labor intensity per cycle was 18.4 man-hours. with a productivity of 3.85 kg/h, which confirms the convergence of research results in laboratory and production conditions. The mass fraction of moisture in the original oil grain was 24-27.8%, and butter - less than 20%, but more than 16%, which meets all the requirements for peasant unsalted sweet cream butter.
