Automatic Potato Grading Machine
The Automatic Potato Grading Machine is designed to separate potatoes according to size. It uses double-sided gradient spiral-driven stainless steel tubes, creating gradually increasing gaps along the conveying direction. Potatoes of different sizes fall through the suitable openings and are collected by separate discharge belts. This enables different potato grades to be packaged, stored, or processed independently.
Potato Size Grader with Stainless Steel Rollers
The Potato Size Grader with Stainless Steel Rollers provides a continuous mechanical solution for separating potatoes by size. As the potatoes move forward, the distance between the stainless steel tubes gradually increases. Small potatoes fall through the earlier openings, while larger potatoes continue to later grading sections.
The equipment is suitable for potato packing houses, agricultural processing plants, farms, and commercial food processing lines.
The Potato Grading Machine for Packing Lines is designed to classify potatoes before packaging. Different sizes of potatoes are separated and transferred to independent discharge belts, allowing each grade to be packed in a suitable way.The gradual gap design helps reduce the mixing of large and small potatoes and supports more consistent package specifications. It can be connected with potato cleaners, inspection conveyors, weighing systems, and packing machines.
The Industrial Potato Size Sorting Machine is suitable for continuous potato processing applications. Its double-sided gradient spiral drive system operates stainless steel grading tubes with gradually expanding spaces.
Potatoes are separated mechanically and discharged onto different belts according to size. The simple and proven working principle reduces the need for repeated manual sorting and improves the efficiency of large-scale potato handling operations.
The Potato Grader with Multiple Discharge Belts separates potatoes into different size grades and directs each grade to a dedicated conveyor belt. The products can then be packaged, stored, or processed according to their size.
The expanding tube gap provides a structured grading process and helps prevent small potatoes from remaining mixed with large potatoes after separation.
Mechanical Potato Grading Equipment


The Mechanical Potato Grading Equipment uses a reliable size separation principle that has been widely applied in agricultural processing. Double-sided spiral-driven stainless steel tubes create a gradually increasing grading gap.
Potatoes fall through the appropriate openings according to their size, while larger potatoes continue moving forward. This mechanical grading method provides continuous operation without depending entirely on manual selection.
More Features for Sorting and Grading Machine
The Automatic Potato Sorting and Grading Machine combines continuous conveying and size classification. As potatoes travel through the stainless steel tube system, the increasing gaps separate them into different grades.
Each grade is collected on a separate discharge belt for further handling. The machine can be integrated into complete potato processing lines, including cleaning, manual inspection, weighing, packing, and storage systems.
The Potato Size Separator for Agricultural Processing is designed for farms, packing stations, and agricultural product processing facilities. It separates mixed-size potatoes into different size categories using a gradient spiral tube structure.
Different potato grades are discharged at different positions and can be handled separately. This helps improve product organization and supports efficient packaging and distribution.
Potato Size Sorting Machine with Gradient Spiral Roller System
The Stainless Steel Potato Grading Machine is manufactured with stainless steel grading tubes for durability and convenient cleaning. The double-sided gradient spiral drive gradually increases the working distance between the tubes.
Different potato sizes fall onto different discharge conveyors, making it easier to manage product grades. The machine is suitable for fresh potato packing, food processing, agricultural cooperatives, and commercial vegetable handling.
The Potato Calibrating Machine is designed to classify potatoes into more uniform size ranges. The stainless steel tubes are arranged with a gradient gap, allowing potatoes to fall through at different points according to their diameter.
Uniform size grading is useful for retail packing, food processing, seed potato handling, and fresh produce distribution. The machine helps reduce mixed-size products and improves downstream handling efficiency.
The Heavy-Duty Potato Grading Equipment is designed for continuous operation in commercial potato processing environments. Its durable stainless steel tube system uses a double-sided gradient spiral drive to create progressively larger grading gaps.
The equipment separates large, medium, and small potatoes into different discharge streams. It can be used as a standalone grader or integrated with potato cleaning, sorting, weighing, packing, and storage systems.
