Our Grader

G5 Grader - includes grader, elevator and separator.

 

The G5 Grader is a magnificent piece of machinery developed over several years in partnership with local South Australian companies to produce a cutting edge product for the oyster industry.

 

The grader is fast, accurate, high quality and has a small footprint making it compact.

 

It has one moving part and is easy to use.

How it works

The oysters travel up an elevator and onto a custom made singulation conveyor that delivers the oysters into the grader at the correct rate.

 

The G5 Grader uses a 4-axis imaging system.

 

There are 4 separate scanners that capture an image of each oyster from 4 different angles as it is falling.

 

Custom electronics and software developed by Oystek combines the 4 images to create a model of the oyster; the model is then analyzed to determine the length, width, thickness and volume of the oyster.

 

The oyster is then directed into one of 8 outputs by a curved chute called the J-Curve, which rotates into the appropriate position for each oyster size.

 

The sizes for the 8 outputs are set up through the touch screen and saved as a grading scheme.

 

Schemes can be easily edited and created as required specific to grower needs.
