Multifunctional fruit grading machine

The Small Packer's Dilemma: Three Problems, One Solution

For small to medium fruit packing houses in Asia, Africa, and beyond, the challenges are remarkably consistent:

Problem 1: Limited space. Most packing facilities weren't designed with large, linear sorting equipment in mind. Adding a grader often means sacrificing valuable floor space — or reconfiguring the entire layout.

Problem 2: Tight budget. High-capacity sorting lines are expensive. For smaller operations, the upfront investment can be prohibitive — especially when the return on investment isn't immediately clear.

Problem 3: Multiple varieties. A packing house that handles apples one week, peaches the next, and citrus the week after needs equipment that can adapt. Buying separate graders for each fruit isn't practical — or affordable.

For years, these three problems meant one thing: many small packers simply couldn't justify automated grading. They stuck with manual sorting — slow, inconsistent, and increasingly expensive.

But that's changing.

A Design That Breaks the Mold

The rotary weight sorter takes a fundamentally different approach to fruit grading.

Instead of a long, straight conveyor line that stretches across the packing house, the rotary sorter uses a circular disc that rotates fruit to weighing cups. This simple design change delivers three breakthrough benefits:

• · Space-saving — The circular footprint takes up a fraction of the space of linear sorters. For packers with limited floor space, this means adding automated grading without sacrificing packing or storage areas.

• · Cost-effective — The rotary design is more affordable to manufacture and maintain than complex multi-lane linear systems. It brings automated grading within reach of smaller operations.

• · Versatile — One machine handles apples, pears, peaches, passion fruit, avocados, oranges, and many other fruits and vegetables. No need for separate graders for each crop.

The result: a grading machine that fits your space, fits your budget, and fits your crop mix.

Gentle Enough for Delicate Fruits

One concern packers often have about automated grading is damage. Will the machine bruise my peaches? Scratch my apples? Crack my avocados?

The rotary weight sorter is designed with gentleness as the first priority.

• · Soft weighing cups cradle each fruit individually — no rolling, no friction during weighing

• · Low-drop discharge minimizes fall height with soft landing surfaces

• · ±2g accuracy ensures precise grading without the rough handling that causes bruising

The result: fruit that leaves the grader in the same condition it entered — no browning, no bruising, no rejections.

One Machine, Endless Possibilities

Here's what makes the rotary sorter truly "multifunctional": it handles a wide range of fruits and vegetables with minimal adjustment.

• · Apples — Sorted by weight for retail-ready packs

• · Peaches — Gentle handling prevents bruising

• · Pears — Consistent sizing for export markets

• · Avocados — Precise weight grading for premium pricing

• · Passion fruit — Delicate handling preserves appearance

• · Oranges & citrus — Uniform sizing for supermarket shelves

  

For packers who handle multiple crops throughout the year, this versatility is a game-changer. Instead of investing in separate equipment for each fruit, one machine does it all.
