Hydraulic sorting of watercore apples.

The results are presented of research on development of a high volume separation device, compatible with existing apple packing lines, for separating fruits affected by water core. The prototype device creates a region of controlled lower density fluid through which fruits pass and in which the fruits are separated. The prototype correctly separated 100% of fruits that were moderately or severely affected (specific gravities more than or equal to 0.90) from those that were less affected, irrespective of fruit size. Fruits that were less than moderately affected (specific gravities between 0.90 and 0.88) were separated from those with slight or no water core with 80-90% accuracy, depending on fruit size. The blind test used 245 Red Delicious apples that were sorted under 5 conditions with 3 replications each.
