Acoustic cavitation technologies are a highly effective means of processing liquid media, as well as various materials in liquid media. They significantly accelerate known processes in liquids and, in addition, make possible the implementation of previously impossible processes. The phenomenon of cavitation has and another quality – the creation around itself of physical fields (including magnetic fields) with high stresses. This circumstance makes it possible to produce some types of work on “dry” technology, for example, to awaken and process seeds before planting. Placing the seeds from the outside of the vortex cavitator causes the magnetic field to be sparing effect on them. Seat placement inside the workspace predetermines a hard impact, so therefore in a real device through the centers of cavitation they move through the tube-seminal duct. The thickness of the walls determines the degree of influence of the physical fields on them.
