Most sorting machines can only handle one fruit type at a time. When mixed fruits come down the line, capacity drops — or sorting stops altogether. Here's how a multi-lane linear weight sorter solves the problem.
The Multi-Species Challenge
Most sorting machines on the market are designed for single-species sorting — they handle apples, or peaches, or citrus, but not all three in the same run.
This creates a real problem for packers who process multiple crops throughout the year — or worse, who receive mixed loads from different growers. Switching between fruits means reconfiguring the machine, recalibrating settings, and losing valuable production time.
For packers handling a variety of fruits — apples, peaches, pears, avocados, passion fruit, and citrus — the question isn't whether they need a multi-species solution. It's which one can handle the volume and precision they need.
The Workflow: From Intake to Output
A modern multi-species sorting line follows a streamlined workflow:
1. Fruit intake — Fruits and vegetables are lifted to the V-belt conveyor, which transfers them into the sorting system
2. Weight measurement — A computer calculates the weight of each fruit with high precision
3. Data comparison — The system compares the measured weight against preset grade parameters
4. Grade determination — Based on the comparison, the system determines the appropriate sorting grade
5. Signal output — The decision is sent to the PLC controller
6. Position tracking — The PLC tracks each fruit's position as it moves through the sorting stack
7. Precision discharge — When each fruit reaches its designated position, it falls into the correct packaging device
The result: consistent, accurate sorting — whether you're processing a single variety or multiple species in the same run.
The Capacity Breakthrough: Multi-Lane Design
For packers handling high volumes, single-lane sorting simply isn't enough. The bottleneck at the grading stage can delay entire shipments and miss market windows.
The solution is multi-lane design.
Fstsort's linear weight sorter offers a significant capacity advantage. Key specifications include:
Parameter | Specification |
|---|---|
Capacity | 25,000 pcs/h per lane |
Lane configuration | 1, 2, or 4 lanes (customizable) |
Number of grades | 7–12 exits |
Weighing range | 20–500 g |
Accuracy | ±2 g |
This means a 4-lane system can process up to 100,000 fruits per hour — a throughput that meets the production needs of most large and medium-sized enterprises.
Precision That Protects Quality
High speed doesn't mean sacrificing quality. The linear weight sorter is designed with gentleness as a core principle:
· Low drop height — Minimal fall distance at every discharge point
· Soft weighing cups — Fruit sits in cushioned carriers — no rolling or friction during weighing
· Food-grade PVC belts — Safe, hygienic contact surfaces
· Sponge-buffered packing tables — Fruit rolls gently to packers at the end of the line
The result: minimized damage during sorting — a critical factor for delicate fruits like peaches, avocados, and passion fruit.
Built for Real-World Packing Houses
The linear weight sorter isn't just about specs — it's about solving real problems:
· For large fruit packers — High-volume processing without the bottleneck of single-lane grading
· For export orders — Fine grading (7–12 grades) meets the tight specifications of international buyers
· For multi-crop operations — One machine handles multiple species with programmable profiles for each fruit
The system also supports flexible integration — from front-end washing options (water flume or soft-touch brushes) to back-end packing options (automatic box filler or sponge-buffered packing tables).

The Smart Choice for Multi-Species Packers
Most sorting machines are built for one fruit. But your packing house doesn't process just one variety. Why should your equipment?
The linear weight sorter delivers the capacity, precision, and flexibility that multi-species packers need — all with the gentle handling that delicate fruits demand.
The technology exists. The question is whether your sorting line can handle more than one species.
