The line for industry is dedicated for washing potatoes with a destination for the processing industry (french fries, specialities and flakes). This line makes us able to remove dirt, stones, sprouts, non usables (e.g. rotten and green potatoes) and floaters (low solid potatoes) from a load of potatoes at a high capacity. We use a salt brine to remove the floaters. A electronic machine inspects the potatoes for non usables such as potatoes with rot, green and growth cracks and for foreign material.
