출구 형상에 따른 기류식 식품분쇄기 시뮬레이션 (Simulation study of Airflow-typed Food Crusher with Varied Outlet Way Shape)

In this study, flow simulation was performed for an airflow type food crusher. The crusher system includes a rawmaterial inlet through which a raw material, such as soybean, is introduced, a motor unit, a housing, a jig, agrinding area (upper casing), an area in which air is injected and distributed (lower casing), an area in which theraw material is discharged and circulated, and upper and lower impellers. In this study, the diameter of the outlet ofthe food crusher chamber was set to three levels (designated Types A, B, and C), and the rate of change in massflow was analyzed. Then, the optimal crusher chamber outlet diameter was determined by comparing the temperatureand pressure inside the chamber by using SOLIDWORKS Flow Simulation.
The mass flow rates were calculated for various diameters of the outlet; the mass flow entering and exiting thetest volume was found to have little effect on the diameter of the outlet. The possibility of thermal damage tothe food raw materials was examined using the simulations. All three models meet the research target of 40 °C orless; therefore, all the models are considered appropriate under the given conditions. Considering the mass flow,temperature, and pressure changes, Type C, which has a large mass flow, is considered to be a suitable model forprocessing capacity and temperature conditions.
