The Kerian Sizer was originally designed for sizing potatoes. Whether replacing a screen sizer, a sieve, or a computerized photoscanner the Kerian Sizer provides an unequalled combination of accuracy, capacity, and price. Recommended for some varieties is a rubber spool roller to rotate the potatoes and separate on four points; others work best with a straight PVC-sleeved roller. In either case, the separation is consistent and effective.
Sizing potatoes for packing for over 60 years, the Kerian Speed Sizer solves your potato grading needs by sorting potatoes onto conveyors that can be custom designed for your warehouse. Grading by smallest diameter will sort your potatoes into sizes to 1/64th accuracy. Our potato sorters are made here in the USA. Each size of potatoes can be customized for the exact sorting you want. Our potato graders are a great value, since the Kerian Speed sizer sorts quickly without damaging product, is low cost and easy to maintain, and pays for itself quickly.
