Methods of separating potatoes from stones and soil clods in storage were evaluated and factors affecting performance were determined. The three methods of separation included a rotating brush separator, an electronic separator and an impact roller separator. All separators effectively sorted the stones from the potatoes but the brush separator failed to differentiate between the soil clods and potatoes. Parameters affecting the performance of the brush separator were the feed rate and the brush gap while the performance of the electronic and impact roller separators was affected by the feed rate and the stone/potato ratio, respectively.
