| Abstract | ||
| Cyclone is a device used to separate the suspended particles in the air or any other gases depending on centrifuge process and swirls without using filters. In this research, a cyclone was designed to separate the dried milk that exit from spray dryer (exist in the Labs of engineering college/University of Tikrit) and then manufacturing the cyclone by depending on the design calculations. The results showed a very high agreement between the design results and the manufactured cyclone results. Design calculations were carried through based on Lapple’s method where the cyclone dimensions, efficiency, and pressure drop for various diameters of milk particles were calculated. Statistical analysis was performed and the results showed that correlation of (R2=97.8%) between the dependent variable (the separated efficiency) at (j) range of particles diameters (ηj) and Independent variables including: (the particles diameter) at (j) range of particles diameters (dj) at (µm), the temperature (T) at (cᵒ) and particles loading (Lp) at (kg/s). The separated efficiency effect proportional with particles loading and inversely proportional with temperature. Volumetric flow rate was 0.14m3/s, velocity was 12.5m/s, the temperature of air and particles loading that depended in manufactured cyclone was 200cᵒ and 0.45kg/s respectively. The collection efficiency for the design calculations was 99.58% and efficiency for the manufactured cyclone was 98.24%. 98.24%. | ||
