Dust is among the major pollutants that have a detrimental effect on the health of pigs and persons working in swine barns. Dust particles vary in size. Heavy particles settle out quickly, however, light particles remain suspended in the barn air representing a more significant threat to people and animals that inhale them. In this study, we designed and tested an aerodynamic deduster prototype that could be affixed to a recirculation duct. We also developed a particle separation theory to test the prototype based on the analysis of particle size.
Factors that affected particle separation efficiency in the aerodynamic deduster included the dedustera
