Our drum-type cherry grading machine provides reliable, automated size sorting, ideal for packers seeking to optimize fruit quality and marketability. The system efficiently separates cherries into consistent size classes using a precision-engineered rotating drum.
Cherry Grading System: Precision Drum Sorter
The heart of the machine is an inclined, rotating drum constructed from durable, food-grade materials. Its surface features carefully calibrated holes that increase in diameter along the drum’s length. As cherries rotate and advance, they naturally separate by size—smaller fruits fall through corresponding holes first, while larger ones continue to the next sections. The drum’s angle and rotation speed are adjustable for optimal handling of different cherry varieties and throughput requirements.
Enhanced Sorting Capabilities: Optical Quality Inspection
For operations requiring more detailed quality control, our integrated optical sorting system delivers advanced evaluation. High-resolution cameras and sensors perform multiple checks:
-
Color & Defect Sorting: Identifies surface imperfections, scars, and color variations.
-
Shape Recognition: Flags misshapen or deformed fruit.
-
Freshness Assessment: Evaluates surface gloss and overall appearance.
-
Optional Internal Quality Analysis: Near-infrared sensors can be added to estimate sugar content and acidity.
This combination ensures a final product that is uniform in both size and visual quality.
Cherry Grading Machine Key Advantages
-
High Efficiency: Streamlines the packing process with consistent, automated sorting.
-
Dual-Technology Benefit: Start with essential size grading and add optical sorting as needed.
-
Flexible Configuration: Customize hole sizes, number of grade classes, and sorting criteria to match your specific fruit profiles and market standards.
-
Gentle Handling: The rotating drum ensures cherries are moved carefully to prevent bruising.
Cherry Grading Machine FAQ
Q: What’s the main difference between a basic drum grader and a full intelligent sorting line?
A: The drum grader is a cost-effective solution focused on accurate size separation. An intelligent sorting line adds comprehensive optical analysis for color, surface defects, and internal quality, offering multi-dimensional sorting for premium markets.
Q: Can this machine sort other types of fruit?
A: Yes. The principle is suitable for various round fruits like blueberries, olives, or small plums. Adjustments typically involve changing the drum (with different hole sizes) and calibrating the optical system.
Q: Can grading standards be customized?
A: Absolutely. We work with you to define the exact number of size grades (from 2 to 8) and quality parameters, ensuring the machine meets your specific packing requirements and product standards.
