We are proud to deliver more than ever before, mastering the art of frying hash browns, summing up benefits with the new drying system and a teaser for some great updates to our batch peeler. Everything for improved processing of potato. We do it together with our clients.
Back in 2003, Rosenqvists Food Technologies revolutionized chip frying with the introduction of the Cold Adjustment Temperature Zone (CATZ). This innovative feature cools the oil in the final zone of the multi-zone fryer—an effective way to reduce acrylamide formation and make your chips safer.
The multi-zone chips fryer gives you unmatched control over temperature and oil flow, allowing you to fine-tune texture. Whether you’re aiming for crispy, crunchy, or something in between, this fryer helps you craft chips with distinct characteristics.
Cut Energy Costs by Reducing Surface Water on Chip Slices
Did you know that excess surface water on chip slices can significantly increase your energy consumption during frying?
After washing, dipping, or blanching, chip slices retain surface moisture that must be evaporated in the fryer—along with the natural moisture inside each slice. This evaporation process consumes a lot of energy. The more surface water present, the more kilowatt-hours (kWh) are needed.
The solution? Minimize surface water before frying. Drying the slices beforehand can lead to substantial energy savings. For example, reducing surface moisture from 12% to 8% can save up to 130 kWh in energy use if you produce 1500 kg of potato chips per hour.
However, it’s important to strike the right balance. A small amount of surface water is still needed to help slices separate and prevent clumping—ensuring a consistent, high-quality product.
You can reduce surface water using:
Vibratory dewatering conveyors
High-speed belts with air blowers
Other customized drying technologies
Need help choosing the right solution for your line? Our sales managers are happy to advise you on the best equipment—and even show you how to measure surface water using a simple centrifugal sieve method.

I’m excited to share the latest updates from Rosenqvists Food Technologies!
In this edition, we highlight key insights we’ve gained over the years in coated French fries production. As demands grow for longer production hours and reduced waste, we continue to innovate—step by step—together with our valued clients.
You’ll also read about our recent innovation award, the benefits of our Inspection Service, and meet some of the new talents who’ve joined our team.
As summer approaches here in Northern Europe, we’re enjoying the sunshine—and I wish you all a wonderful and relaxing season ahead.
Here’s what we’ve learned about coating of french fries
Producing clear-coated French fries—or other potato products with thick, heavy coatings—comes with its own set of challenges. At Rosenqvists Food Technologies, we’ve spent years refining our coating systems to help our clients achieve longer production runs with less waste and easier cleaning.
Here are some of the main challenges we’ve tackled:
Keeping machinery clean and hygienic
Preventing excess coating mix from entering the first-stage fryer
Reducing waste of expensive coating mix
Maximizing production uptime
Through continuous innovation, we’ve made significant improvements in both design and performance. Today, some of our clients run their coating lines for several weeks without major interruptions. Here’s what we’ve learned along the way:
1. Easy Access for Cleaning
Clean equipment is essential for food safety and consistent product quality. Our designs focus on accessibility:
Tiltable setting conveyors make cleaning easier during wash cycles
Open-frame construction allows cleaning even during production
Movable fine filters improve access and hygiene
Integrated cleaning systems can include the entire coating mix unit
2. Gentle Handling of the Coating Mix
Maintaining the quality of the coating mix is crucial. We’ve optimized our systems to reduce stress on the mix:
Specialized pumps or screws minimize shear and preserve texture
Cooled drip trays and pressure-resistant systems help maintain temperature stability
Tubular heat exchangers keep the mix cool during circulation
Every drop of coating mix counts. Our systems are designed to reuse and recirculate as much as possible:
Adjustable air blowers remove excess coating before frying
Optimized setting conveyors with the right length and turning points reduce loss
Spray and drip tray systems help recover coating during production
Our goal: Lower Total Cost of Ownership
Every design improvement we make is aimed at reducing operational costs for our clients. By combining long production runs, efficient cleaning with minimal water use, and reduced coating waste, we help food producers achieve a more sustainable and profitable operation.

Our team is back from Snackex in Stockholm, full of inspiration and energy. We got the chance to catch up with many clients and partners. What are the takeaways from Snackex, at least from our perspective?
Firstly, the snacks industry is full of positive people and companies with plans for growth. It is just inspiring to learn about your exciting ideas for product innovation and other plans for a more efficient production process. Great to be a part of an industry with so many creative plans.
Continued focus on the energy challenge and efficiency in production. We followed a number of presentations at Snack Science Hub (sponsored by Rosenqvists) highlighting sustainability or producing more with less input, as some would express it. Improved energy efficiency in Snack Baking from Reading Bakery Systems, increase yield with pulse electric field technology from Elea and of course a summary of possible short and long-term energy savings when producing potato chips from our own R&D Manager Magnus Kalling.
Product development driven by healthy and natural ingredients is something that stands out. Ideas for nutritious snacks, concepts for healthier products and a range of new natural ingredients were presented at the show. We stopped to taste snack products with new flavours from around the world. It is fun and inspiring. This development is a result of skilled product developers and new opportunities in the world of ingredients.
Finally, from Rosenqvists Food Technologies, we showcased the improvements made to our Star Wheel Frying system, the easy-to-use snack pellet frying system driven by electrical heating. The online dashboard from a 1000 kg/hour chips line were demonstrated. We had discussions on new types of snack products, and we could explain how we can avoid wasting vegetable oil in frying systems for nuts, a tough challenge in terms of frying technology. We are proud to have a system allowing our client to minimize the risk of oil waste. Distribution system and seasoning system were also presented in the Rosenqvists booth. We have a complete range enabling us to compile a processing line from potato intake to packaging.
We will continue to develop the 3rd generation chips fryer for the sustainable and green production facility of the future. When we meet up in Lisbon, Portugal in 2026, we look forward to presenting more news.
*Stockholm, Sweden – June 19-20, 2024* – Rosenqvists Food Technologies is excited to announce our participation in the upcoming Snackex exhibition in Stockholm this June. We are thrilled to engage with fellow colleagues, partners, and especially our valued clients within the snacks industry.
