__Sorting of fruits __ The fruits are sorted based on different properties of the fruits. There are different type of sorting of fruits. For example, weight sorting, color sorting, blemish sorting, diameter sorting, shape sorting, density sorting and internal/ taste (N.I.R).

Here is an example of a company that is responsible in sorting of fruit that is Compac.

 For weight sorting, there is electronic weighing system to determine the weight of the fruits for example the Compac sorting machines. The system is specifically designed for accurate high speed weighing of produce from 25 to 2000 grams. The fruit carriers and load cell runners are designed so that each carrier is being measured for over 95% of the weigh cycle, giving maximum time for precision weighing, even at high speeds of 10 to 15 fruit per second per lane. The weight of every single empty carrier is recorded and used as an individual tare weight and is updated every time that the carrier is weighed empty. This compensates for changes through the packing day, effectively calibrating itself automatically. 

 The second type is color sorting. In Compac company, there is Compac's InVision 5000 system. Compac InVision 5000 captures multiple images of each fruit at standard production speeds of up to 15 fruit per second.

GRADING IMAGING The next type is Blemish sorting. This is available for oranges, lemons, tomatoes, mandarins, apples, kiwifruit, pomegranates, avocados and potatoes. It is sorts for surface marks, stains, insect damage, cuts, punctures and bruising.
 * Color - Up to 16 user defined colors can be graded
 * Hue - Average color of the fruit (green to red for tomatoes, yellow shades for lemons, etc)
 * Shape - Elongation, flatness and symmetry
 * Diameter to within +/- 1mm accuracy
 * Volume (Oranges and other fruits) with 2mls standard deviation
 * Detects bridging fruit (pieces incorrectly located in carriers) and doubled fruit (two pieces of fruit in one carrier) if required
 * Captures up to 25 images for an individual piece of fruit

 * <span style="font-family: 'Comic Sans MS',cursive;">Automated camera control for correcting light changes

<span style="font-family: 'Comic Sans MS',cursive;"> For shape sorting, there are some examples:

<span style="font-family: 'Comic Sans MS',cursive;">Onions is separated by its elongated shapes. Kiwifruit is separated by its flat or fanned shape. Lemons are separated by its elongated shape.
