The Automatic Blueberry Sorting Machine For Circular Fruit Diameter Sizing is a specialized solution designed to handle the delicate nature and uniform grading requirements of blueberries. As blueberries are small, soft, and easily bruised fruits, this machine adopts a gentle yet highly accurate diameter-based sorting system to ensure consistent sizing for fresh markets, export packaging, and further processing. It is widely used in blueberry packing houses, farms, and fruit processing facilities to improve efficiency, reduce labor costs, and enhance product quality.
This blueberry sorting machine operates based on circular fruit diameter grading technology. Fresh blueberries are evenly fed onto the conveyor system, where they are distributed into rotating grading rollers or circular sizing units. As the rollers move, blueberries pass through adjustable gaps that correspond to different diameter ranges. Smaller berries fall through earlier gaps, while larger ones continue forward until they reach the appropriate grading outlet.
The entire process is designed with soft contact surfaces and controlled movement speed, ensuring that blueberries are sorted accurately without damaging their skin or affecting their freshness and bloom.

Preservation of "Bloom": The low-friction design ensures the silver-white waxy coating of the blueberry—a sign of freshness—is not rubbed off.
Unmatched Sizing Accuracy: Eliminates human error, providing consistent diameter grading down to the millimeter level ($12mm, 15mm, 18mm+$, etc.).
High Throughput: Replaces the labor of 10-15 manual sorters, drastically reducing operational overhead.
Low Maintenance: Built with stainless steel (SUS304) and high-wear-resistant components for 24/7 harvest season operation.
Soft-Touch Food Grade Material: All contact surfaces are lined with medical-grade silicone or soft polymers to prevent bruising.
Multi-Stage Grading Customization: Equipped with adjustable sizing holes or gaps that can be tailored to specific blueberry varieties (e.g., Duke, Bluecrop, or Southern Highbush).
Variable Speed Control: Integrated with a PLC frequency conversion system to adjust sorting speed based on fruit ripeness and volume.
Compact & Modular Design: Small footprint that integrates seamlessly into existing cleaning and packing lines.
