he COLOR & SIZE SENSOR can be incorporated into any commercial sorting line which uses a cup-conveyor or roller-conveyor for transporting the fruits. Each COLOR & SIZE SENSOR incorporates three sets of photodiodes which view each fruit from three directions. The fruit size is determined by the average of the signals from the 3 photodiodes while most of the fruit's surface is included in the color determination. As the fruit passes underneath the photodiodes the computer acquires about 1,000 readings from each sensor. The color and size values are averages of these readings.
