Optimization of Screw Mixer to Improve Drying Performance of Livestock Manure Dryer Using CFD Analysis

Scarcity of fossil fuels and their emissions fuel pollutants, such as carbon dioxide, into the atmosphere, resulting consequences, have led energy policymakers to look for alternative renewable clean sources. The use animal wastes is one very promising alternatives paving way a more sustainable network. Animal manure produced by livestock farms has moisture content about 80%, dehydrated 20–25% solidified be used biomass thermal power plants. Previous studies on dryers been concentrated convection-type dryers, but this type dryer disadvantage inadequate processing capacity per hour because it cannot agitate manure. In study, deal with drawbacks conventional drying methods, screw-type was proposed. CFD analysis performed selecting viscosity design parameters screw using Ansys Workbench. Through response surface method, optimal shape improvement efficiency smooth discharge residual carried out.
