Abstract:	This study explores the design, fabrication, and performance evaluation of a plantain trunk shredding machine aimed at enhancing the efficiency and quality of fiber extraction for industrial applications. The machine was designed to be driven by a 2 horsepower engine, with a flat–belt driving system operating at an angle of lap of 2.87 rad on the smaller pulley. The resultant load acts on a shaft with a diameter of 14.6 mm, experiencing a maximum bending moment of 18.338 Nm. The total weight of the shaft, pulping drum, and bearing on the frame was 66N. Performance tests conducted revealed that the machine performs optimally at a moderate operational speed of 1420 rpm. The machine demonstrated an efficiency of 96%, effectively pulping plantain ribs of approximate thicknesses ranging from 7 mm to 9 mm with applied forces of 150 N, 200 N, and 250 N, respectively. The shredding machine achieved slicing pseudo stem thicknesses between 4.0 mm and 10 mm in 12 to 20 seconds. These results indicate that the plantain trunk shredding machine is highly efficient and suitable for industrial applications, significantly reducing processing time and labor costs while maintaining high–quality fiber production.
