ABSTRACT
This experiment is dedicated to study the impact of essential technical and engineering parameters on the performance of an agricultural residue shredder for producing non-traditional ruminant nutrition. The study was carried out in the workshop of Agriculture college at Ain Shams University in Egypt, during the academic year of 2023-2024. The investigation tested two shredder knife speeds of (1300 vs 1500 rpm), two feeding rates of (1.5 vs 3 kg.min-1), and two penetration angles of (20° vs 30°). The evaluated technical traits comprised: productivity, cutting efficiency, total required power, and specific energy. The moisture content of palm frond was 39%. The findings displayed that the greatest recorded productivity was 108.23 kg.h-1, with the highest shredding efficiency was 87.67%. The least overall required cutting power was 1.040 kW, furthermore, the least recorded specific energy value was 0.01255 kW·h·kg⁻¹. These results indicate that optimizing shredder knives’ velocity and feeding rates can lead to enhance efficiency and reduce the energy consumption in agricultural residue handling, contributing to a more efficient feed production. The Statistical System that was adopted for Analysis was Genstat Discovery Edition 4. To analyze the data according to a split experiment in a randomized complete block design (RCBD), the Least Significant Difference (LSD) test p< 0.05 was used to compare the means.
