This work examines aerodynamic modeling of the process of air cycloning in a direct-flow cyclone. The most important technological operation in the food industry is to achieve a high degree of dusty air purification. The practice of operating cyclones testifies to the discrepancy between the actual efficiency of the apparatus and the real capabilities of dust collecting installations. The modern development of industry is characterized by an ever-increasing intensification of various technological processes, which is accompanied by significant dust formation. The problem of collecting dust affects almost all branches of modern production. These are the production of building materials, metallurgy, woodworking, chemical and food industries. In this regard, the problem of maintaining the cleanliness of the air basin of cities arises, and increased requirements are imposed on dust-collecting equipment. Along with the requirement to ensure minimum dust emissions, dust-collecting equipment should be completely reliable for a long time of operation and not require large costs for installation and maintenance. For dust collection of dust, cyclones are now widely used, the principle of which is based on centrifugal separation of the mixture. In the food industry, the most widespread are cyclones of spray units “Niro-Atomizer”, “VRA-4”, “Nema-500”, A1-ORCH. The cyclones of the listed installations differ from each other in the number of devices installed in the dust collection system, design features and aerodynamic modes of air purification.
