For small orchards and packing houses, space is money. A grading machine that takes up half the shed leaves no room for storage, packing, or movement. Here's how a compact rotary weight sorter delivers professional-grade sorting without consuming your workspace.
The Space Problem No One Talks About
When you walk into a small packing house, you notice it immediately: every square meter counts. There's no room to spare. A bulky grading machine doesn't just take up floor spaceāit forces you to compromise on storage, packing tables, and worker movement.
For small orchards and medium-sized packers, the choice often comes down to: do I automate grading, or do I keep my workspace functional?
The answer used to be "you can't have both." Not anymore.
The Fstsort rotary weight sorter is designed around a simple principle: professional-grade sorting in a footprint that fits your space. Its circular design takes up a fraction of the floor space of traditional linear sorters. No more sacrificing storage for sorting. No more tight aisles between equipment.

What the compact design means for your operation:
Challenge | How the Rotary Sorter Solves It |
|---|---|
Limited floor space | Circular footprintāfits where linear sorters canāt |
No room for expansion | Wheels on legsāmove the machine as your layout changes |
Tight budget | Affordable entry pointāautomation without breaking the bank |
Complex installation | Simple structureāeasy to install and operate |
Precision That Doesn't Take Up Space
Small space doesn't mean small capability. The Fstsort rotary sorter processes 15,000 pieces per hour with ±2g accuracyāthe same precision you'd expect from a much larger machine.
Each fruit is carried individually in a soft weighing cup to a rotating disc. The system weighs every piece, then directs it to one of 6 weight grades (6+1 exits) based on its weight. No rolling. No friction. No guesswork.

The result: consistent, accurate gradingāwithout the bruises and damage that come from traditional mechanical graders.
Key capabilities at a glance:
Feature | What It Means for You |
|---|---|
15,000 pcs/h | Enough throughput for small to medium operationsāno bottlenecks during peak harvest |
±2g accuracy | Consistent gradingāevery fruit goes to the right market channel |
6+1 exits | Six weight grades for marketable fruit, plus one dedicated exit for culls |
30ā500g range | Covers most fruitsāfrom small apples to large avocados |
Soft weighing cups | Gentle handlingāno bruising, no post-sorting browning |
One Machine, Dozens of Fruits
Small orchards often grow multiple varieties. Apples one week, peaches the next, citrus in between. Buying separate graders for each fruit isn't practicalāor affordable.
The rotary weight sorter handles apples, peaches, pears, avocados, citrus, tomatoes, onions, potatoes, and more. Switch between crops without changing machines.

For packers who handle a mix of fruits and vegetables throughout the season, this versatility isn't just convenientāit's the difference between one machine and a shed full of equipment.
