Apple grading machines sort apples and other round fruits quickly and accurately. Using mature rotary drum grading technology, this machine sizes apples based on their diameter through different sieve sections on the drum.
Robust, easy to operate, and built to last, it’s the perfect solution for orchards and fruit processing centers that want to move beyond manual sorting and improve post-harvest value.
Apple Grading Machine Working Principle
The machine features an inclined cylindrical drum made from perforated stainless steel.
- Automatic Feeding: Apples are evenly fed into the drum via a conveyor or elevator.
- Rotary Grading: The drum rotates at a low speed. Apples roll and move forward; those smaller than the current aperture size naturally drop onto the discharge chute.
- Segmented Discharge: The drum is divided into 2–5 zones with different hole sizes (e.g., Φ60, 70, 80, 90mm). Each zone produces a specific grade—like Premium, Class I, and Class II.
- Gentle Handling: Graded fruits fall onto cushion trays or conveyor belts, minimizing bruising.
Key Advantages
✅ High Accuracy: Precision-punched apertures ensure consistent sizing and prevent misgrading.
✅ Zero Damage: Low rotational speed and no internal spiral pusher allow apples to separate naturally by rolling, preserving the fruit wax and flesh.
✅ Wide Applicability: Suitable not only for apples but also for potatoes, citrus, walnuts, onions, jujubes, and other round or oval produce.
✅ Durable Construction: Made of SUS304 food-grade stainless steel, resistant to corrosion and impact, ideal for humid and harsh environments.
