The Role of Technology in Modern Potato Processing

Advanced machinery and systems have revolutionized various stages of potato handling, from cutting to sorting, significantly improving product quality, consistency, and production rates.

High precision cutting equipment ensures uniform potato pieces, whether for French fries, chips, or other products, leading to better cooking results and customer satisfaction.

Optical sorting technologies, utilizing cameras and lasers, can rapidly inspect potatoes for defects, foreign materials, and size variations, maintaining high quality standards and food safety. Automated conveying systems and robotic handling reduce manual labor, minimizing product damage and contamination risks. Additionally, data-driven process control systems optimize resource usage, reduce waste, and ensure consistent output quality.

These – and other – technological advancements not only boost productivity and profitability for processors but also contribute to more sustainable operations by maximizing yield and minimizing energy consumption. As consumer demands for quality and variety continue to evolve, the integration of cutting-edge technology in potato processing remains essential for staying competitive in the global market.

According to Alan Major, chief sales officer at Urschel, the company has maximized slice engagement with the patented MicroAdjustable series heads which greatly reduces miscuts and increases in-spec, targeted cuts. This translates to increased usable products and consistent fry times, less oil, and cost-savings. Urschel has showcased its new MicroAdjustable series of potato slicing heads for the Model CC, and Alan Major explains its benefits.

“The MicroAdjustable SL-14 series patented by Urschel for the Model CC maximizes cutting action with 14 cutting stations versus the fully adjustable, standard 8-station head, so customers benefit from potentially doubling the capacity. Options on the CC include a 22″ (559 mm) or 32″ (813 mm) cutting chamber. Customers with the 813 mm cutting chamber, paired with an SL-14 head, and powered with a 5 HP (3.7 kW) or 10 HP (7.5 kW) recognize tremendous benefits.”

The MicroAdustable SL-14 flat slice heads manufactured by Urschel allow slicing knives to be replaced quickly without tools and without removing the head from the machine when equipped with quick release clamps. The Urschel patented SlideLocc system incorporated in the .212″ V MicroAdjustable SL-14 head uses a simple angled wrench and optional tools. The head is removed from the machine using the 2 lift handles conveniently built into the design. The angled wrench is used to loosen fasteners. The optional torque wrench may be used to loosen or tighten the fasteners. The customer slides in the blade, locks in place, and then tightens, Major explains.

Potato processors also explore further size reduction capabilities via the Comitrol Processor line of particle size reduction machinery manufactured by Urschel. The line mills food products into free-flowing, viscous slurries to provide value-added opportunities. The Comitrol milling series by Urschel operates by incrementally shearing the product in a rapid, controlled manner called comminution. The Comitrol particle size cutting solution has assisted thousands of food processors to extend and build their capabilities and SKUs. „Urschel customers are looking for higher and higher capacities. The big processors are looking for standout potato products to continue to stay ahead of their competition. New cuts and decreased waste,” Major says.

“Urschel partners with leading potato processors to develop new shape cuts and cutting methods. Urschel personnel assist potato processors around the globe to make sure we are fully supporting the needs of the industry. Urschel engineering and product development engage with food processors to create new patented cutting methods and improve on existing ones to meet present and future goals.”

Regarding the equipment’s operating and maintaining side of things, Urschel’s global network of sales and service spans the globe. “As the global leader in food cutting technology, Urschel customers have relied on us to deliver the right cutting machinery for the needs of their production line,” Alan Major points out.

“Founded in 1910, Urschel food cutting machinery, is proud to have grown alongside the food processing industry. An Urschel customer may begin with a test-cut on different types of Urschel machinery to determine the best fit. Complete information about each model may be discussed in depth. Urschel communicates with customers to answer questions specific to their requirements including any operational or maintenance topics. After the sale, service and support continues. Service is available over-the-phone or in the customer’s plant for any necessary training. Urschel is available for scheduled maintenance and service as needed by the customer. In-depth operating manuals depict concise, clear procedures. Urschel also maintains a multi-million-dollar inventory of commonly replaced parts available for shipment on customer demand. Each part is engineered to fit and function like the original.”

Additionally, Urschel offices surround the globe to assist and partner with leading potato processors. Urschel respects these relationships and honors all exclusivity agreements. Leading processors benefit from Urschel’s in-depth cutting and manufacturing knowledge backed by the assistance, support, and security they need in a long-term capital equipment provider. While the Urschel Model CC Slicer is well-known throughout the world as the leading crisp/chip slicer, the DiversaCut line has been gaining momentum in niche potato products. There are more and more potato products bridging the gap between crisps/chips and fries. Niche markets in waffle cut fries, lattice crisp/chip slices, and small cut frites are continuing to expand.

More Innovations to Come

“Urschel takes part in every major food processing industry show around the globe. Urschel has been showcasing the MicroAdjustable series, the many knives we manufacture, and the latest machinery to view first-hand. We are proud to be a leader in the food processing industry and have recently revamped the look of our booths with a complete redesign,” according to Alan Major.

“Emphasized in the new booth design are the many types of food products processed with Urschel cutting machinery support. Urschel will continue to represent the best in cutting technology at shows around the world. It’s important to meet new and existing Urschel customers and help them strategize successful cutting solutions to improve their production lines. Urschel standard slicers and dicers have more optional features than ever before, such as built-in discharge conveyors, longer infeed belts, door swing options, motor size, and more. The new Model CC Slicer frame design is an example of the strides Urschel is continuing to implement. While Urschel accommodates custom requests through a certified print process, customers often decide optional features on a standard machine will fit their objective. Custom type requests are put through a certified print process. With the certified print process, Urschel works with the customer to fulfil specific build requirements, and the resulting machine cost will generally be higher than when purchasing a standard machine,” he adds.

Future innovations and developments from Urschel include even more shape cuts, Major points out. “We are in the process of developing new patented cutting methods that have the potential to be unveiled in the next two years pending extensive research and development. Urschel will also continue to expand on developments on existing machinery in the field to help Urschel customers expand their opportunities.”
