Product Overview – Three Sorting Technologies for Tomatoes
Fstsort offers three dedicated sorting technologies for tomatoes. Each can work independently or be combined into a complete line.
Sorting Technology | Principle | Best for |
|---|---|---|
Drum Grader | By diameter | Round tomatoes, basic size sorting |
Electronic Weight Sorter | By weight (±2g accuracy) | Uniform weight grading for packing |
Optical Sorter | By external blemish (color, shape, defects) | Premium quality, export-grade tomatoes |
✅ All three technologies are customizable (capacity, number of grades, lanes, material). Tell us your needs, and we will design accordingly.
Option 1 – Drum Grader (Diameter Sorting)— High Value, Low Cost
The drum grader is our most affordable tomato sorter. It is designed for packers who need reliable diameter sorting without complex automation.

Description:
This line includes automatic feeding hopper, roller elevator & inspection table, and drum size sorting machine. It sorts tomatoes by diameter. Each section can work separately or be combined into a processing line according to your requirements. Working speed is adjustable. We can add a water tank for washing if you need.
Application: Tomato, mandarin, tangerine, and similar round fruits.
Typical parameters (customizable):
Parameter | Typical Reference Range |
|---|---|
Capacity | 5– 10 t/h ((customizable) |
Number of grades | 3 – 6 (customizable) |
Sorting range (diameter) | 15mm – 120mm |
Voltage | 220V / 380V / custom |
Material (fruit contact) | Stainless steel |
Frame material | Carbon steel / stainless steel |
✅ Best for: Basic size sorting, budget‑friendly, smaller operations.
Option 2 – Electronic Weight Sorter (Flexible Configuration)– Higher Accuracy (±2g)

For customers who need weight-based grading rather than diameter, we offer an electronic weight sorter. This system is highly flexible – we configure it according to your capacity, packing requirements, and budget.
Typical parameters (customizable):
Parameter | Typical Reference Range |
|---|---|
Accuracy | ±2g (depending on configuration) |
Number of grades | 6 – 12 exits |
Capacity (per lane) | 25,000 pcs/h/lane |
Number of lanes | 1, 2, 4, or 6 lanes (configurable) |
Weight range | 50g – 500g (adjustable) |
Touch screen control | Yes – with data recording |
Fruit contact material | Stainless steel / food-grade plastic |
Best for: Uniform weight packing, export orders, integration with automatic packing lines.
Option 3 – Optical Sorter (Photoelectric Sorter)

The tomato sorter by photoelectricity sorts products by diameter, color, shape, and blemish (external defects).
Detects: Surface blemishes, bruises, discoloration, unusual shapes
Technology: High-speed cameras + sorting mechanism
Number of outputs: Customized
Integration: Can be placed upstream or downstream of other sorters
Best for: Premium export markets, defect removal, high‑quality packing lines.
