| dc.description.abstract | Pineapple (Ananas comosus L.) is a tropical fruit extensively consumed
and processed into various food products. Manual peeling of pineapple skin and
core is labor-intensive, time-consuming, and poses occupational safety risks. This
research aims to develop the design of a pineapple skin and core peeling machine
employing a pneumatic system and to evaluate its performance through
computational simulation using SolidWorks software. The research methodology
comprises functional and structural design analysis, engineering calculations,
technical drawing development, static structural analysis, and kinematic
simulation. Design specifications reveal overall dimensions of 65 cm × 40 cm ×
60 cm, incorporating principal components: stainless steel 204 cutting blades, SC
50×200 pneumatic cylinder, 1 HP compressor with 8 bar operating pressure, and
ST 37 steel L-profile structural frame. Engineering calculations establish the
required peeling force of 88.3 N at 0.451 bar operating pressure. The pneumatic
actuation system generates forward and retraction piston forces of 982.14 N and
973.09 N respectively, consuming 2.92 liters of compressed air per operational
cycle. Finite element analysis demonstrates maximum frame stress of 72.58 MPa,
displacement of 0.494 mm, and safety factor of 1, confirming adequate structural
integrity and load-bearing capability. Kinematic simulation validates consistent
blade operation within a 5-second operational cycle. The proposed design
presents a technically feasible solution for prototype fabrication, potentially
enhancing operational efficiency in pineapple processing applications. | en_US |
