Abstract
The rapid expansion of the poultry industry had led to significant challenges in managing the vast amounts of waste generated. This study addresses these challenges by developing a mechanical pelleting machine for poultry manure, converting it into nutrient-rich organic pellet fertilizer. this study was conducted to test and evaluate the performance of the machine in terms of pelleting capacity, pelleting recovery and moisture content of the output. The final testing of the study was conducted at CLSU Layer Poultry, Central Luzon State University, Science City of Muñoz, Nueva Ecija from March to May 2024. The developed pelleting machine, with a capacity of 17.5 liters. The machine's prime mover was gasoline engine with a speed reducer attached. the machine was fabricated using locally available materials, mainly steel, further emphasizing the practical approach. The treatments made in the performance evaluation of the machine were the different initial moisture content and different speeds of the conveyor. The lowest pelleting capacity was obtained at low speed-semi dry with 59.49 kg/hr and the highest pelleting capacity was obtained at high speed-slurry type with 85.9 kg/hr. The lowest pelleting recovery was obtained at low speed-semi dry with 76.9% and the highest pelleting recovery was obtained at high speed-slurry type with 89.35%. The treatments were analyzed using factorial Analysis of Variance with a Completely Randomized Design (CRD) and the comparison among means was done using Least Significant Differences.
