Product Overview
FstSort provides potato processing solutions, from standalone adjustable roller graders to complete cleaning and grading lines. Our systems seamlessly integrate with automatic filling, weighing, and crating units. From precise sizing to the final box, we deliver a unified, factory-direct automation solution tailored to your specific packaging needs.
Potato Roller Grader – Basic Adjustable Model
The Fstsort potato roller grader is the foundation of our potato processing line. This standalone unit sizes potatoes by width/diameter with high accuracy and gentle handling. It is ideal for packers who need efficient size sorting without a full washing line, or as the core grading module in a larger system.
How the Adjustable Roller Grader Works
The machine uses a series of forward-moving rollers:
Bottom bed: Fixed rollers
Top bed: Height-adjustable rollers
Every top roller is mounted in a polymer guide plate, allowing it to lift vertically to create a specified grade size. This design ensures precise sizing while remaining gentle on potatoes.

Potato Receiving Hopper
Product description:
A potato receiving hopper is a piece of machinery, usually located at the entrance of a processing line, that receives and temporarily stores potatoes before they are sorted and processed.
How it works: A potato receiving hopper is usually a large, open container with a sloped bottom that allows potatoes to be unloaded from a truck or trailer and transferred into the hopper. The hopper may be equipped with a conveyor or other loading device to assist in transferring the potatoes into the hopper. Once the potatoes are in the hopper, they are stored until they are ready to be sorted and processed.
Advantages：
Increased efficiency: A potato receiving hopper allows potatoes to be quickly and easily unloaded from trucks or other vehicles, which can help to increase the overall efficiency of the unloading process.
Efficient: Potato receiving hoppers are designed to be efficient and able to unload potatoes in a timely manner, helping to minimize delays and keep operations running smoothly.
Preliminary cleaning: The receiving hopper is equipped with cleaning rollers and other devices. After the potatoes enter the hopper, the dirt and impurities on the surface of the potatoes can be initially cleaned by the rolling of the cleaning rollers, etc., so as to reduce the soil content on the surface of the potatoes and reduce the burden of subsequent cleaning processes.

Frequently Asked Questions
Key questions customers usually ask before choosing this solution.
Can the grading size be adjusted for different potato varieties?+
Yes. Our adjustable roller grader allows you to easily change the spacing between rollers. This flexibility enables you to sort various potato sizes or satisfy different market standards with a single machine.
Can the machine automatically pack potatoes into boxes?+
We offer scalable solutions to meet different needs. Our standard machines and full processing lines support capacities ranging from 5 to 20 tons per hour, making them ideal for both medium-sized farms and large industrial wholesalers.
Does the brush cleaner require water?+
Yes. We offer a fully integrated Automatic Filling, Weighing, and Crating System designed in-house. Once the potatoes are graded, the system automatically fills each container, weighs it to your exact specifications, and moves it forward for final crating. This eliminates manual labor and ensures high efficiency and weight accuracy.
How does the machine minimize bruising on potatoes?+
Protection is our priority. Our machines feature low-drop heights, soft-touch materials at impact points, and smooth conveyor transitions to ensure even the most delicate "new potatoes" are handled without skin damage or bruising.
Can I customize the layout to fit my warehouse?+
Absolutely. Whether you have a narrow space or a wide facility, we can design the line in Linear, L-shape, or U-shape configurations. We also customize the number of grading outlets and manual sorting table lengths to match your specific workflow.
