AI-driven Sort-to-Grade


28 September 2022
Good news for potato processors.

KEY Technology has introduced AI-driven Sort-to-Grade® (STG) which, when used with digital sorters, will enable potato processors to eliminate traditional mechanical length graders. 

Advanced AI algorithms allow STG for potato strips to digitally resolve clumps of overlapping product and better identify the individual strips, which maximises its precision in measuring the length of each strip on the production line.

STG recognises and categorises every surface defect and the length of every individual strip to make each accept/reject decision based on how it will impact the ‘in the bag’ grade, as defined by the processor. Length profiles can be changed in seconds via the sorter’s touchscreen UI.

By digitally monitoring the length of every strip on the line, processors can rely on an AI-driven STG-enabled sorter to analyze the length profile of potato strips immediately prior to packaging and forgo taking physical samples off the line for length analysis using a separate device.

Additionally, the length data collected by AI-enhanced STG can be used to improve line performance and/or generate reports that verify the length profile of each batch. The sorter can collect, analyse and share data to reveal patterns and trends that help control upstream and downstream processes.

The new AI-driven STG is an option available on every new Key digital sorter for potato strips including VERYX, and it is available as a field upgrade for most installed Key potato strip sorters.
