Conclusion


Rotary tray made whole elongate fruit inspection
possible.


Automation system enable more labor saving as
well as provide a means of recording information
on the quality of each fruit (fruit feeding and
packing operations.)


Automation will improve the traceability of
eggplants in the food distribution system, which is
increasingly important in addressing the issues
related to food quality and safety.
