Purification of crude unrefined sunflower oil along with the removal of primary oxidation products is an urgent task to remove the solid constituents formed during the processing of sunflower seeds. All of them irrespective of the chemical composition negatively affect the quality of the food product and, over time, saturate the oil with coagulants that affect its organoleptic and physico-mechanical characteristics. The problem of cleaning unrefined sunflower oil by filtration with the use of vibroacoustic action is considered. The calculation scheme of the process is given, and an experimental setup has been developed that makes it possible to vary the angle of inclination of the filter element. The research of sunflower oil filtration in the field of vibroacoustic impact is carried out. In the study, a decision was made to expand the energy effects to create a cumulative system in the liquid medium that improves the hydrodynamic situation at the scale of the oil purification plant. It is established that the process speed can be intensified by creating additional microflows that provide an active influence on the motion of liquid, gas and solid particles. The results are obtained, which testify to the effectiveness of the use of vibroacoustic effects during the filtration of sunflower oil.
