Citrus Fruit Grading Machine Roller Type Citrus Sorter

Our citrus fruit grading machine utilizes advanced roller gap adjustment technology, specifically designed for the automatic size sorting of various citrus fruits such as oranges, lemons, tangerines, and grapefruits. This machine achieves precise, damage-free grading through a physical gap principle, making it a core sorting equipment for the citrus packaging, export, and processing industries.

Citrus Sorting Equipment Working Principle

1. Roller Conveying System
Using parallel-arranged food-grade rollers, citrus fruits move smoothly and rotate naturally on the rollers, ensuring that all sides of each fruit come into contact with the grading gap.

2. Adjustable Gap Grading Zone
The grading area is designed with a progressively widening gap; the gap between adjacent rollers gradually increases from the inlet to the outlet. Citrus fruits smaller than the current gap naturally fall into the corresponding collection chute.

3. Multi-stage Sorting and Collection
The standard configuration allows for simultaneous sorting of 4-7 size grades, with each grade having an independent discharge channel that can be directly connected to a packaging line or transfer bins.

4. Extra-Large Fruit Collection Guarantee
An extra-large fruit collection area is provided at the end to ensure that all sizes of citrus fruits are accurately sorted into their corresponding grades, with a sorting accuracy of ±2mm.
