Horizontal roller grader

The Cabinplant horizontal roller grader is designed for size grading raw cold water shrimp. It is used to pre-grade the shrimps into two or three sizes in order to facilitate the determination of cooking time.

The grader consists of two through-going screws with increasing pitch (helix), one on each side. Horizontal stainless steel rollers are mounted between the two screws and connected by a stainless steel chain on each side. The rotating rollers gently transport and grade the product as the space between the rollers progressively increases.
