Better French Fry Coating Lines: Rosenqvists Food Technologies Shares Insights and Solutions

Producing clear-coated French fries or other potato products with thick, heavy coatings comes with its own set of challenges. At Rosenqvists Food Technologies, has spent years refining the coating systems to help the company's clients achieve longer production runs with less waste and easier cleaning.

Here are some of the main challenges Rosenqvists has tackled:

• Keeping machinery clean and hygienic
• Preventing excess coating mix from entering the first-stage fryer
• Reducing the waste of expensive coating mix
• Maximizing production uptime

Through continuous innovation, the manufacturer has made significant improvements in both design and performance. Today, some clients run their coating lines for several weeks without major interruptions.

Here’s what the company has learned along the way:

Easy Access for Cleaning

Clean equipment is crucial for maintaining food safety and ensuring consistent product quality. The company's 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

Gentle Handling of the Coating Mix:

Maintaining the quality of the coating mix is crucial. Rosenqvists has optimized its 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
• Insulated batter enrobers prevent condensation issues
