Diameter Sizer

Tough and reliable, the Diameter Sizer is used for both dry and wet receiving, and at the cutter deck for peeled potato products. It precisely grades product by diameter; or can be configured to remove dirt, rocks, and other undesirable materials. The field-proven Diameter Sizer has been in use for over 20 years. Hundreds are now in use in processing plants, grading beets, onions, carrots and potatoes.

The bed of the Diameter Sizer consists of a series of sizing rollers. Each roller comprises a steel shaft and “finger” style rubber rollers spaced at a calculated distance along the shaft. The “fingers” from each sizing roller mesh with those of the adjacent rollers, creating a hole at each mesh point where targeted product falls through to discharge under the machine. The rollers turn in the direction of line flow, conveying remaining product to discharge at the end of the machine.
