Protect your harvest with our advanced weight and optical sorting system. Engineered for delicate fruits like apples, our "soft-handling" technology prevents bruising from washing to packing.
Advanced Apple Sorting Solutions: Precision Grading with Zero-Bruise Technology
Product Overview – Built for Fragile Fruits
Apples are the gold standard for testing equipment gentleness – they bruise so easily that if a machine handles apples well, it handles any fruit well. Our machine is designed with what we call "Apple-Standard Care" :
Protection Feature | How It Works |
|---|---|
Water flume feeding | Fruits float into the system – water acts as a natural cushion, eliminating bruising from dry dumping |
Soft-touch brushes | Ultra-soft, food-grade bristles polish without micro-scratching |
Suspended weighing | Fruit sits in deep, ergonomic carriers – no rolling or friction during weighing |
Low-drop discharge | Minimal fall height with soft landing surfaces |
✅ The result: Minimized post-sorting browning – a common problem with traditional mechanical graders.
Application – Delicate Fruits That Need Gentle Handling
Best for: Apples, peaches, pears, avocados, mangosteens, passion fruit, kiwis, plums, tomatoes, and citrus.
Three Sorting Technologies
Option A – Rotary Weight Sorter (Compact, Economical)
The rotary weight sorter uses a rotating disc to feed fruit to weighing cups. It is compact and affordable, ideal for small to medium packers.
Parameter | Reference Range |
|---|---|
Capacity | 15,000 pcs/h |
Number of grades | 5+1 exits |
Weighing range | 30 – 500 g |
Accuracy | ±2 g |
Footprint | Compact (circular design) |
Best for:
Small to medium fruit packers
Limited floor space
Budget-conscious buyers
✅ Gentle handling – low drop height, soft weighing cups.
Option B – Linear Weight Sorter (High Capacity, Multi-Lane)
The linear weight sorter uses a straight conveyor belt to feed fruit to weighing cups. It offers higher capacity and more grades.
Parameter | Reference Range | Customizable |
|---|---|---|
Capacity (per lane) | 25,000 pcs/h/lane | ✅ Yes (1–4 lanes) |
Number of grades | 7 – 12 exits | ✅ Yes |
Weighing range | 20 – 500 g | ✅ Yes |
Accuracy | ±2 g | ✅ Yes |
Lane configuration | 1, 2, or 4 lanes | ✅ Yes |
Capacity by lanes:
Best for:
Large fruit packers
Export orders requiring fine grading (7–12 grades)
Integration with automatic box fillers
✅ Gentle handling – low drop height, soft cups, food-grade PVC belts.
Option C – Optical Sorter (Color, Size & Defect Detection)
The optical sorter uses high-speed cameras to sort fruit by color, size, and external defects. It has no physical contact with the fruit – the gentlest option available.
Detectable Features | Examples |
|---|---|
Color | Redness percentage, green spots, uneven ripening |
Size | Diameter (in addition to weight) |
External defects | Bruises, scars, russeting, rot, insect damage |
Parameter | Reference Range | Customizable |
|---|---|---|
Capacity | 8–10 t/h (4-lane system) | ✅ Yes |
Number of grades | Up to 16+1 exits | ✅ Yes |
Sorting criteria | Color, size, weight, external defects | ✅ Yes |
Cameras | Multi-angle, high-speed | ✅ Yes |
Best for:
Premium fruit packers (export markets)
Removing defective fruit automatically
Color sorting (e.g., 80% red apples)
✅ Zero physical contact – cameras only, no touching. The gentlest method for delicate fruits.

Frequently Asked Questions
Key questions customers usually ask before choosing this solution.
Why is this machine better for thin-skinned fruits like apples?+
Most graders use hard plastic drops. Our system uses a proprietary "Soft-Landing" mechanism and synchronized belt speeds to ensure that the fruit never experiences a high-impact fall.
Can I integrate this with my existing water tank?+
Yes. Our modular design is compatible with various water-feeding and dry-feeding systems.
