Tuned for Tubers: Optimizing Conveyor Tech for Potato Processing Lines

Whether designed for French fry production, flake manufacturing, chip slicing, or IQF packing—the conveyor system is far more than a means of transport. It is a critical part of the hygiene infrastructure, an enabler of product consistency, and a core element in overall line efficiency.
As automation advances and throughput requirements climb, conveyor systems must now accommodate not just high volumes, but also strict sanitary design, minimal maintenance, and delicate handling where needed. And with space constraints tightening in many plants, footprint and modularity also come into play.
Among the most established suppliers for the potato processing industry, Key Technology has developed a comprehensive line of vibratory conveyors that are well-suited for raw, wet, and frozen potato product handling. Their Iso-Flo, Impulse, Zephyr, and Marathon models are all designed to manage extremely high throughputs—up to 45,000 kilograms per hour in some configurations—while maintaining consistent flow and alignment. Built in stainless steel and featuring oil-free drives, these conveyors are commonly used to singulate, spread, dewater, or align product streams ahead of downstream operations like optical sorting, cutting, blanching or freezing.
Because they use tuned vibratory motion rather than belts or rollers, product damage is minimized and sanitation is simplified. In particular, the lack of enclosed moving parts and the open bed design reduces the risk of bacterial harborage and facilitates fast, effective washdowns. Key’s systems are frequently found not just in standalone applications but integrated into full lines, working in concert with sorters and optical graders, and are backed by a five-year warranty—a rarity in industrial equipment.
Ashworth, another major supplier with deep roots in food processing, brings a different strength to potato facilities. Their spiral and turn-curve belts allow processors to move product vertically or along complex layouts where space is limited. For example, washed and peeled potatoes that must be conveyed to higher levels for further processing often rely on spiral conveyors where linear belts would take up too much floor space. Ashworth’s Omni-Grid 360 Weld and PosiDrive Spiral designs feature crevice-free surfaces, smooth welds, and tension-controlled movement—all of which contribute to improved hygiene and reduced cleaning time.
These features are especially relevant in wet environments such as post-peeling or hydro-cutting areas, where stainless steel components must endure daily cleaning with caustics and hot water. Their SmartSpiral remote monitoring platform adds a layer of predictive maintenance, alerting operators to belt fatigue or performance deviations before they result in costly downtime.
This level of control, paired with Ashworth’s in-house technical service teams and global spare parts availability, makes them a trusted name where hygiene and layout optimization intersect.
One of the newer entrants to gain traction in hygienic conveyor systems is Dynamic Conveyor, whose DynaClean S-Series was launched in 2024. Originally developed for broader food processing markets, the S-Series has found increasing relevance in potato processing, especially in wash, peel, and trim areas. Its design philosophy centers on modularity and tool-free disassembly. Conveyor frames are built from HDPE and UHMW plastic rather than stainless steel, which offers high resistance to chemical cleaning agents and eliminates crevices where soil and moisture could accumulate. Sidewalls, chutes, scrapers and belt supports can all be removed without tools, allowing sanitation crews to perform complete disassembly, cleaning, and reassembly in a fraction of the time required for traditional systems. Belt options include solid polyurethane and link-style polypropylene, both FDA-approved and suitable for direct food contact. For potato processors looking to reduce changeover times and sanitation labor hours, DynaClean offers a cost-effective solution that doesn’t compromise on performance or compliance.
Complementing these systems are several lesser-known but equally critical technologies that support hygienic performance and process reliability. Fortress Technology, a company better known for its metal detection systems, provides tool-free belt removal systems for conveyor lines that need frequent sanitation. Designed originally for bakery and snack food environments, these mechanisms are increasingly being adopted in potato processing where similar cleaning demands apply. By enabling operators to remove and reinstall belts without tools, these systems reduce the risk of incorrect reassembly and eliminate the possibility of losing fasteners during cleaning—an often overlooked source of foreign body contamination. The ability to restore full belt alignment immediately after sanitation also cuts down on startup waste and idle time.
