The Tri-Pak Rod Sizer System is a durable, high-efficiency produce sizing solution engineered to deliver accurate sorting for post-harvest packing operations. Designed specifically for oblong produce, the system uses a transverse rod conveyor to stratify product by diameter while maintaining gentle handling and consistent throughput.

The sizing surface consists of closely spaced transverse rods positioned at predetermined gaps that allow smaller-diameter produce to pass between the rods while larger product continues downstream. This method provides reliable mechanical sizing for crops such as cucumbers, squash, peppers, and other elongated produce where diameter is a more useful grading characteristic than overall length.

Designed for flexible integration into both new and existing packing lines, the Rod Sizer System operates as an inline sizing stage within a broader processing system and can be configured in sequence to create multiple size grades for precise sorting and packing applications. As produce advances across successive rod sections, each stage progressively separates product into increasingly refined diameter ranges.

Every unit is equipped with adjustable leveling feet to ensure produce flows evenly across the full width of the sizing surface for efficient and consistent throughput. Units are available in either stainless steel or painted mild steel construction, with power configurations ranging from 120V single-phase to 575V 3-phase. An optional Variable Frequency Drive gives operators greater control, allowing them to fine-tune conveyor speed to optimize product presentation and sizing performance.

Reliable, modular, and built for the rugged environment of a packing house, the Rod Sizer is a field-proven solution for packers requiring efficient high-volume diameter grading of oblong produce. With routine maintenance and periodic wear-component replacement, the Tri-Pak Rod Sizer System is engineered to provide accurate, repeatable performance for decades of continuous operation.
