Impact analysis using an instrumented sphere. -->

The use of an electronic recording device known as an instrumented sphere to identify and quantify impacts experienced by fruits and vegetables on mechanical handling equipment is discussed. Since 1990, trials throughout Australia have used the sphere to assess packing facilities for export apples, oranges, tomatoes and onions; grading and sorting equipment for canning peaches and pears; harvesters for crisping and table potatoes; and table potato packing lines. The sphere's impact acceleration range, size and movement characteristics have proved to be well suited to studies of these particular crops. Data output from the sphere allow a direct quantitative comparison of sites causing drops and collisions. The damage potential of sites can thus be relatively established and used as a basis for equipment modification to reduce impact size and number. On harvesters and automated handling lines, transfers between components, rather than movement through components, are the primary source of large im

pacts. In a trial on apple cv. Jonathan, bruise characteristics were correlated with the sphere's impact acceleration readings.
