Rotary tray made whole elongate fruit inspection Rotary tray made whole elongate fruit inspection possible.possible.

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

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