Description
High Precision Potato Sorting Grading Machine Roller Bar Type is a high-precision grading machine designed for potatoes and other root vegetables. It adopts the classic roller bar sorting structure and has continuous, automated, and high-capacity grading capabilities. Its sturdy stainless steel frame and adjustable roller gap design enable the equipment to accurately classify potatoes into multiple grades according to diameter, meeting the stringent requirements of food processing plants, agricultural cooperatives and exporters for product consistency and standardization. Depending on the model, the production capacity can range from 2 tons/hour to 10 tons/hour, covering the needs of small, medium and large production lines.

Frequency control: equipped with a variable frequency control system, the operator can adjust the conveying and roller speed according to the processing volume and sorting effect to achieve precise control;
Multi-level outlet discharge: each level gap corresponds to a different size, and the potatoes fall into the corresponding grading belt according to the diameter and are automatically conveyed to the next process or container equipment;
Loading and uniform feeding: potatoes are loaded into the elevator and evenly fed into the roller grading area through the conveyor belt;
Roller automatic grading: a series of fixed-spacing rollers are arranged in parallel to convey the potatoes forward, and the gradually increasing gaps allow smaller potatoes to automatically fall and complete the grading;

Frequency control: roller and conveyor belt speeds are adjustable to meet different sizes and production requirements;
Food grade material: stainless steel and PVC rollers, corrosion-resistant, rust-proof, and easy to clean;
Modular design: divided into lifting, grading, and conveying modules, supporting cleaning and maintenance;
Potato Sorting Machine Advantages
Automated operation: Reduce labor, the equipment can run continuously 24/7, greatly improving efficiency.
Low energy consumption and quietness: The motor power is 0.75–3kW, low noise, suitable for factory environment
High-precision sorting: ±2mm sorting accuracy is achieved through roller gap adjustment to ensure product consistency.
Low breakage return rate: The roller has a flexible structure, gently contacts the potatoes, and reduces mechanical damage.
Potato Sorter Machine Benefits
Save labor costs: Automatic grading replaces manual screening, saving a lot of manpower expenses every year.
Reduce defective rate: small potatoes are not mixed with large specifications, which greatly reduces the waste of discarded products.
Improve product circulation efficiency: It can be directly connected to the packaging and processing lines to improve downstream efficiency.
Improve brand standardization: The diameter of potatoes of all grades is stable, which is suitable for packaging and customer specifications.

Conclusion
High Precision Potato Sorting Grading Machine Roller Bar Type significantly improves the efficiency and quality of potato grading with its high precision, multi-level sorting, automatic control and food-grade material advantages. It is an ideal equipment for modern potato processing and export processing enterprises. Whether it is a small or medium-sized farm cooperative or a large-scale food processing plant, this equipment can achieve product standardization and maximize production efficiency.
