The Lemon Fruit Grading Machine Roller Type is specifically designed for grading and classifying lemons by size. Lemons are typically round or nearly round citrus fruits, with significant variations in diameter and size, requiring precise grading before packaging, export, or further processing. This roller-type grading machine uses a roller mechanism to classify lemons by size (diameter/shape), ensuring that each batch of lemons leaving the factory or being handed over to the next process is consistent in size and clearly graded. It is suitable for use in fruit and vegetable processing plants, post-harvest lemon sorting workshops, and export packaging lines, effectively improving production efficiency and product consistency.
The core of this roller-type grading machine lies in the use of a series of rollers (or cylinders) to form the working surface. After lemons enter the machine via a conveyor or feeding mechanism, they are spread out in a single layer on the roller surface. As the equipment operates, the lemons roll on the rollers and are automatically classified according to their diameter and shape through the gaps between the rollers or at the discharge port.
Specifically: The rollers are driven by a drive chain or reducer, and the fruit moves forward with the rotation of the rollers. Discharge channels or drop ports are set at different diameters (or gaps). Once a lemon reaches a certain size threshold, it "falls out" of that grade and enters the corresponding grade channel. Throughout the process, the equipment structure is mostly made of stainless steel, with protective features, adjustable grading channels, and simple operation.

The frame and rollers are made of food-grade stainless steel, meeting hygiene requirements. For example, the "Fruit and Vegetable Roller Grading Equipment" specifies the use of stainless steel tubing.
Adjustable roller gap and grading channels: The equipment can be set to grade lemons of different sizes, ensuring accurate grading.
Integrated roller drive and conveying design: Lemons are naturally conveyed and rotated during rolling, ensuring sufficient "tumbling" for more accurate size judgment.
Multi-level grading capability: For example, it can grade from 4 to 8 levels to meet different packaging specifications and market requirements.
For lemons, due to their relatively regular shape, roller grading achieves good size consistency and fast grading speed.
Simple operation and low labor intensity: Automated roller grading reduces manual sorting, thereby lowering human error rates and labor costs.
Minimal damage to the peel: Roller grading involves minimal collisions and pressing, making it suitable for fruits like lemons that require maintaining their appearance integrity.
Flexible adaptation to different specifications: Manufacturers can set different diameter ranges according to market demand, accommodating bulk exports and packaging grade changes.
Improved Lemon Packaging Consistency: After grading, lemons of similar size across each grade result in better packaging and stronger after-sales consistency.
Increased Subsequent Processing Efficiency: For export or processing companies, uniformly sized lemons facilitate automated packaging, weighing, and boxing, thereby improving overall production line efficiency.
Reduced Defect Rate and Return Risk: By grading and removing excessively large, small, or irregularly shaped lemons, customer satisfaction is improved, and quality issues are reduced.
Higher Market Value: High-specification, uniformly sized lemons are more readily accepted in high-end or export markets, thus increasing profit margins.
In summary, the Lemon Fruit Grading Machine Roller Type Sorter for Size Classification is a size grading device specifically designed for lemons. With its roller-based grading principle, adjustable size channels, multi-level grading capabilities, and low-damage treatment of the peel, it provides a professional and efficient solution for bulk lemon sorting, packaging, and export processing. Whether you are a lemon production base, a deep-processing plant, or an export packaging company, this equipment can help you improve grading consistency, reduce labor costs, and enhance product quality.
