The Kerian Sizer has been proven throughout the world as the best and most affordable sorters for seafood, known to be gentle, accurate and quick. The opening between the rollers consistently and slowly increases as the rollers carry the crawfish forward.  Straightened rollers eliminate any pinching or squeezing during sizing.

For most crawfish graders, an aluminum pan is positioned underneath the rollers so that the crawfish slide to the side of the Sizer, neatly sorted by size.  Dividers above the pan can be moved to quickly adjust the sizing. 

For high volume systems, instead of an aluminum pan, takeaway conveyors can be positioned a few inches below the rollers to carry the crawfish to the side of the Sizer.
