Structural Performance Analysis of a Two-Stage Orange Juicer and Peel Shredder Machine Frame Using SolidWorks Simulation

Abstract

The increasing demand for processed orange juice in small and medium-scale agro-industries has highlighted the need for machinery capable of performing both juice extraction and peel-waste shredding in a single integrated system. This study aims to analyze the structural strength of the frame and assembly of a two-stage orange juicer and peel shredder machine using computer-aided simulation, ensuring that the designed structure can withstand the torsional and static loads generated during operation without experiencing structural failure. The frame was constructed from ASTM A525 galvanized steel angle profile measuring 50 x 50 x 4 mm, selected for its adequate mechanical strength, ease of fabrication, and economic availability. The research combined a literature review, three-dimensional modeling in SolidWorks 2022, and static structural simulation, followed by manual theoretical calculations of von Mises stress, displacement, and safety factor for verification purposes. The total static load applied to the frame, derived from the combined mass of the motor, hopper, squeezing cylinder, filter, shaft, and collection tank, was 310 N. The simulation results showed a maximum von Mises stress of 25.7 MPa, well below the material yield strength, indicating that the structure remained within its elastic limit. The maximum displacement obtained was 0.296 mm, and the resulting safety factor reached 8, both of which fall within acceptable design limits. Manual calculations produced higher stress and displacement values than the simulation, with discrepancies attributed to simplifying assumptions inherent to analytical beam theory. Based on these results, the frame design of the orange juicer and peel shredder machine is considered structurally safe and feasible for the intended operating conditions.
