A device for the production of environmentally friendly butter with a rotary-blade working body is presented. The research technique for substantiating the optimal parameters is presented. Based on the theory of probability and mathematical statistics, the regression equation describing the energy intensity of the process of whipping butter is determined. When solving it, the optimal design and kinematic parameters of the device for the production of environmentally friendly butter were revealed with a churning capacity of 13.4 kg/h, a butter yield of 59.5% and a fat loss of less than 0.4%. The rotational speed of the rotor-blade working body is np=422 min-1; the number of blades of the rotor-blade working body zр=3; the capacity filling factor φzap=0.57. Evaluation of the economic efficiency of introducing a device for the production of environmental friendly butter will reduce the energy intensity of churning by 24% compared with the mass-produced EMB-01 Salyut.
