The Tri-Pak Shrimp Sizer is a precision roller grading system designed to sort shrimp by size in commercial seafood processing operations. Using a series of adjustable stainless steel rollers, the system separates shrimp by thickness as they pass through the grading zone, delivering sized product to individual output chutes or runout conveyors for collection or downstream processing.

The Model 7330 vertical shrimp grader features twelve stainless steel rollers, each four feet long, adjusted simultaneously via two hand wheels to set the desired size gap across the grading zone. Rollers are powered by a single motor through a V-belt and gear drive for smooth, quiet operation. A wet hopper at the infeed spreads shrimp evenly across the roller width to ensure consistent distribution and grading accuracy. A water spray system over the rollers keeps product wet and promotes smooth passage through the grading zone. The complete unit is mounted on casters for easy repositioning.

For larger operations, a six-lane classifier configuration is available featuring 24 precision rollers each ten feet long. The lower 12 rollers incorporate two machined flats 180 degrees apart to enhance shrimp separation consistency. This configuration includes a rotating wet hopper, overhead spray, baffles at the first and last chutes, and four 12"-wide x 10' Intralox product runout conveyors with individual motors and drives. The system can be configured for left-hand or right-hand operation.

All components are fabricated from stainless steel for full washdown compatibility in seafood processing environments. The Tri-Pak Shrimp Sizer delivers accurate, high-throughput size separation for commercial shrimp processing operations requiring dependable, sanitary grading equipment
