Potato washing, inspection and grading line

This line runs potatoes from washing through to sizing, and the videos on this page were filmed on HJV equipment in operation.

Stones come out at the start, through an integral de-stoner mounted on the washer, before they can damage product or wear machines downstream. After washing, potatoes cross roller inspection tables, where the blue background and LED lighting help the crew catch defects and debris, and then a grader module sizes them onto cross conveyors.

Each machine in the line was laid out to feed the next. Want to see what a wash and grade line would look like in your building? We start with a 3D layout you can walk through.
