The experiments of this study were carried out to optimize some pelletization parameters and their effects on the quality of feed processing. The pelletizer was evaluated under different parameters including feeding rate and feed pellets. Pelletization process was evaluated by studying the specific energy consumption and quality of feed pellets at different operation conditions. The pelletization energy consumption ranged from 179.14- 204.60 kJ/kg for rabbits, 163.60- 184.87 kJ/kg for poultry and 41.06- 59.67 kJ/kg for large animal feed pellets. The compression and shear forces of pellets ranged from 277.16- 309.11 and 30.12- 38.02 N, respectively for rabbits feed pellet, 99.22- 106.08 and 25.60- 29.60 N, respectively for poultry feed pellets and 135.63- 242.08 and 59.92- 104.66 N, respectively for large animals feed pellets. |
