Mechanical equipment and operations used in avocado, papaya, and pineapple packing lines can cause bruise drainage resulting in post-harvest losses. An Instrumented Sphere (IS) was used to record impacts occurring in commercial packing lines for these fruit. The IS was able to identify transfers that caused high impacts in each line. Impacts from each packing line were also classified relative to impacts on known surfaces. Improvements in all of these lines can be made by adding cushioning to bare steel surfaces, replacing worn cushioning, reducing elevation changes between components, and controlling fruit flow at each transfer. Impact tests to establish bruise damage thresholds with each fruit are needed to determine impact and fruit conditions which result in bruise damage. Improved handling conditions can then be identified to maintain fruit quality.
