Product Overview – Gentle, Adjustable Grading for Brussels Sprouts
Brussels sprouts vary significantly in size across a single harvest. To maximize market value, processors need to sort them into consistent diameter grades. Our roller grading machine is designed specifically for this purpose – gentle on the sprouts, easy to adjust, and built for continuous operation.
Key features:
✅ 3–6 grades – customizable number of exits
✅ Adjustable roller gaps – change sizing ranges without replacing parts
✅ Inner width – 1000mm to 1500mm (customizable)
✅ Capacity – 3 to 5+ t/h depending on configuration
✅ Soft handling – stainless steel rollers + soft belt at connection areas
✅ Pre-sorting option – remove loose leaves before grading
💡 All parameters are customizable – grade count, size ranges, inner width, and belt layout are designed to your specific requirements.
How the Roller Grader Works
Step | Process |
|---|---|
1 | Brussels sprouts are dumped into the automatic feeding hopper |
2 | Optional pre-sorting rollers allow loose leaves to drop through |
3 | Main roller bed moves sprouts forward; gaps between rollers gradually increase |
4 | Sprouts fall through at the appropriate gap size onto takeout belts |
5 | Each size is carried to its collection point (box, bin, or conveyor) |

Size adjustment: Each exit has an adjusting handle and ruler mark – simple to change size ranges from 15mm to 75mm. No tools required.
Pre-sorting option: Roller hopper before the grader catches loose leaves – cleaner fruit, less debris.
Flexible Takeout Belt Configurations
We offer multiple takeout belt layouts to match your collection method and floor space.
Standard Layout – All Exits on One Side
Best for: Small to medium packing lines, standard boxes or crates, limited floor space.
Configuration: All exits discharge on the same side of the machine.
Typical setup: Packing table or simple bin at each exit – easy for 1-2 workers to manage.
Split Layout – Left + Right Sides
Best for: Large box collection, high-volume lines, better worker access.
Configuration: Alternate exits split between left and right sides (e.g., exits 1,3,5 on left; 2,4 on right).
Benefits:
More space for workers on each side
Better for large containers (e.g., 1600mm long boxes)
Prevents bottlenecking at collection points
✅ We can customize belt length, belt height, and left/right split according to your floor layout and container dimensions.
