Precision Grading with Zero-Bruise Technology
Product Overview – Built for Fragile Fruits
Our automatic weight sorting machine is designed with gentleness as the first priority. Whether you process apples, peaches, pears, citrus, or avocados, the machine ensures minimal damage and maximum accuracy.
Protection Feature | How It Works |
|---|---|
Water flume feeding (optional) | Fruits float into the system – water acts as a natural cushion, eliminating bruising from dry dumping |
Soft-touch brushes (optional) | 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, citrus, and other 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.
