A vibratory oil maker to produce environmentally friendly butter is presented. A constructive scheme and design of a butter maker with a churning mechanism in the form of a flexible vibration drive (a membrane that is also the bottom of the container, which performs periodic oscillatory movements by means of a crank mechanism) has been developed, which reduces the energy intensity of churning and loss of butter due to its sticking to the churning mechanism. A force analysis is presented, in which the forces acting in the oil maker during its operation are considered and a formula is obtained for determining the power to drive the vibratory oil maker, considering the division of masses into rotational and reciprocating masses of the vibratory oil maker knocking down mechanism. The power for the drive of the vibratory oil maker was calculated considering the change in the angle of rotation of the crank φ = 0...360 degrees. The obtained values are presented as a graph of the dependence of the power on the drive on the angular velocity and radius of the crank at given angles of rotation of the crank. The maximum (peak) value of power per drive is determined - 125 W. At the same time, the energy intensity of butter churning of the vibratory oil maker was Es = 3.84 Wh/kg with a productivity of Qm = 11.25 kg/h, and the degree of use of milk fat S = 99.6%, which corresponds to the waste of fat into buttermilk 0.4% and does not exceed the requirements of GOST.
