Miedema graders excel at accurately sorting your product and preventing product damage. This means a high-quality end product and a higher net yield. Perfect accuracy, less manpower, maximum yield!

Our product range includes numerous roller and web graders, which sort accurately by size. The graders are very flexible in use and can easily be incorporated into the storage line.

Fully automatic potato sorting

If you want the highest standard in potato sorting, consider the highly praised Smart Grader. This optical unit can sort by size, shape and colour. Wireworms, rhizoctonia, growth cracks, rot, scab and discolouration (green) are detected and automatically diverted. This gives you an accurately graded and even higher quality end product. It is this performance that allows the Smart Grader to immediately provide you with higher yields.
