Split Grader
Up to 160 tons per hour
A mobile pre-storage cleaner that takes rocks, clods, golf balls and debris out before potatoes go into storage, at up to 160 tons per hour with a TOMRA 3A optical sorter.
Grader Module
A screen grader for potatoes, onions, beets and bulbs, with triple short-throw agitators and a push-and-pull drive, in widths from 900 to 2400 mm and three lengths.
The Grader Module sizes crop on screens driven by triple short-throw agitators and a push-and-pull drive mechanism. It's a well-proven, robust design for high-capacity, accurate grading of potatoes, onions, beets and bulbs.
Pick a width from 900 mm (36") to 2400 mm (95") and a short, standard or long module: 1.4, 1.7 or 2.0 m. Cross conveyors carry each size away, and spacer belts can line them up with automatic box handling.
Screens tension simply, a tuber eject roller lifts long potatoes off the screen before the pintle drive roller, and hexagonal steel screens handle onions and bulbs. An interchange facility lets you move modules when you change sizes.
