ROTARY DEVICE

FIELD: machine engineering.SUBSTANCE: rotary device includes an electric motor 1 and a mixing chamber 2 provided with a supply pipe 3 and a discharge pipe 4 and coaxially arranged discs of a rotor 5 and a stator 6 with elements for generating the cavitation process in the liquid product being processed which fills the mixing chamber 2. The elements for generating the cavitation process are placed on the working surfaces of the mentioned discs opposite to each other in alternating concentric circles. Each element for generating the cavitation process is made in the form of the de Laval nozzle or an attachment similar to the de Laval nozzle, tangentially mounted on the working surfaces of the rotor disc 5 at a distance (A) and the stator disk 6 at a distance (A') from the axis of the corresponding disk, wherein the values (A) and (A') are determined by the following dependencies: 0,1D≤A
