The nozzle element of the mass transfer apparatus comprises a body made in the form of a mesh sphere, inside which at least one freely rotating element is mounted on a transverse axis. The transverse axis of the freely rotating element is mounted inside three frames, the outer frame being fixed with the possibility of rotation inside the mesh sphere, the middle frame being fixed with the possibility of rotation inside the outer frame, and the inner frame being fixed with the possibility of rotation inside the middle frame. The axes of rotation of adjacent frames are located in mutually perpendicular planes
