Impact detection in potato handling lines with sensors based on tri-axial accelerometers. Mechanical damage in potato postharvest processes has become a major concern for potato producers.The amount of potatoes rejected by the Spanish potato industry because of severe bruising increases annually.Mechanization and automation of the postharvest processes raise the production capacity but the potatoes run an increased risk of getting damaged by mechanical impacts.In this work the use of “electronic potatoes” – were used in the tests: the PTR 200 (SM Engineering, Denmark) and the IRD 400 (Techmark Inc., USA).

The experiments were carried out in four grading and packing centers in the main potato production area of the Northwest ofSpain.The four storehouses were equipped with different machines.The tests were focussed o­n the determination of (1) the number and type of drops, (2) the drop heights, (3) the transportation velocity, (4) the velocity changes and (5) the changes in direction of transportation.The impact data obtained from the two electronic potatoes were compared to examine any possible differences in performance of the two electronic devices.
