Machine performance in pelletizing poultry litter
Öz
Objective: This research investigates the pelletizing performance of the machine used to process poultry litter. Fresh poultry litter poses challenges due to its high moisture content and volume per unit weight. Handling large volumes at low density over long distances is both difficult and expensive.The objective of this study is to employ a simple machine to transform poultry litter into the desired shape and volume weight, thereby improving storage, transportation, and off-site utilization.
Material and Methods: The research aims to assess the impact of five different moisture content levels (11%, 17%, 26%, 34%, and 47% d.b.), four die diameters (4 mm, 6 mm, 8 mm, and 10 mm), and three auger speeds (1.2 m/s, 1.8 m/s, and 2.4 m s-1) on pelletizing efficiency (%), broken pellets (%), and pelletizing capacity (kg h-1).
Results: The results indicate that optimal pelletizing efficiency (%) and minimum broken pellet percentage (%) were achieved at a moisture content of 26%, an auger speed of 2.4 m s-1, and a die diameter of 4 mm. Maximum pelletizing capacity (kg h=1) was attained with a moisture content of 47%, screw auger speed of 2.4 m s-1, and a die diameter of 10 mm.
Conclusion: Therefore, it is recommended to operate the simple machine at an auger speed of 2.4 m s-1 for optimum results.
