Radial Grader

The radial grader from Allvege Process Technologies is engineered to sort a wide variety of vegetables, such as carrots, potatoes, onions, parsnips, beets, rutabaga, flower bulbs, and other similarly shaped produce. The Allround radial grader uses a two-dimensional grading system to efficiently separate produce based on diameter. Grading sizes can be set either manually or automatically, with adjustments available on all belts except the last one, which is dedicated to the largest size.

Produce is moved and rotated over rollers, with the distance between the rollers gradually increasing. As the produce advances, smaller items fall first, while larger items drop later. These are collected onto belts that continue transporting them. Multiple belts are arranged for different size ranges, and adjustable angles help the produce drop accurately, allowing sufficient time for precise sorting.

Characteristics

  • Side panels can be removed for easy access to internal components
  • Separates produce based on diameter using rotating rollers with gradually increasing spacing.
  • Smaller items drop earlier while larger items continue along the rollers for accurate sorting.
  • Each size group is directed onto its own conveyor belt for organized and continuous handling.
  • Belt angles can be adjusted to enhance sorting accuracy and control product drop timing.
  • Grading sizes can be set either manually or automatically.
  • Designed for efficient, precise, and gentle handling of produce.
  • Anti-lift feature on all belts except the last prevents rollers from being lifted by elongated items.
  • Frame options include painted mild steel, stainless steel (AISI304), or zinc-coated painted mild steel, while bearings and drive/idler rollers are consistently manufactured from mild steel.
