Феликс Яковлевич Рудик The paper is devoted to the issues of ensuring high nutritional characteristics of vegetable oils in the production and prolongation of their storage. Basing on the research of well-known scientists, the authors studied the process ofsunflower oil filtration in the adsorbent layer with acoustic ultrasonic intensification of the process. Basing on the results of the analysis and systematization of information on the spoilage of unrefined sunflower oil with primary and secondary oxidation products, the authors theoretically analyzed the impact of acoustic micro-flows on the filtering process and the filtering element (cartridge), developed an experimental installation for the purification and regeneration of unrefined oils, studied the kinetic laws of the filtering process and designed a machine-hardware scheme of the purification of unrefined vegetable oil after storage. Also, they calculated technical and economic efficiency of an installation for filtering unrefined sunflower oil with the use of acoustic ultrasonic action. Filtering of unrefined sunflower oil was carried out with an experimental ultrasonic installation with theoretically and experimentally determined oscillation amplitude a = 4.52-5106 m and oscillation frequency f = 18-20 kHz, with a possibility of regulating the inclination angle of the filtering element. The authors experimentally obtained kinetic regularities of the filtration process with the use of vibro-acoustic influences on crude sunflower oil, presented research materials on the concentration of pollutants in the treated oil, the permeability of the filtering partition depending on its contamination, and set the indicators characterizing the quality characteristics of the purification of crude oils. The work performed allows improving the quality and cleaning performance, prolonging the shelf life of crude and unrefined sunflower oils.
