Complete systems for coated fries and other cut potato products

Coated French Fries

In today’s potato product industry, coatings enhance items like french fries and wedges to create desirable textures and flavors. At Rosenqvists Food Technologies, our batter mixer and enrober system are designed to ensure uniform coating coverage on each product before frying, achieving the high-quality finish customers expect.

The process begins with the Rosenqvists Batter Mixer, which precisely controls the batter’s viscosity and temperature. Once the coating reaches the ideal consistency, it’s transferred to a circulation tank and then pumped to the enrober.

Before entering the coating stage, cut potatoes pass through an aligning shaker, ensuring they are evenly spaced to allow full-width coating application in the Rosenqvists Enrober. Excess coating is removed using air blowers, with setting conveyors allowing precise control, which keeps production areas cleaner and reduces batter waste.

Our Double Frying System features the lowest oil volume in the industry, promoting rapid oil turnover for fresh, waste-free frying. During the initial frying stage, our system maintains single-layer product placement to prevent the batter from forming lumps or causing products to stick together. The adjustable infeed belt facilitates this separation, allowing each product to fry individually.

Once the coating is set in the first fryer, we reduce speed in the second fryer to handle a larger product volume. This two-step approach ensures even frying and a smooth, continuous flow of products to subsequent processing stages.

Preparation

Aligning infeed shaker: The specially designed infeed shaker ensures that each product is separated before entering the batter applicator.

Coating

Batter mixer: The coating is mixed in the batter mixer, which controls the viscosity and temperature of the batter. The batter is pumped to a circulation tank and from there, it is pumped to the applicator/enrober.

Batter applicator/enrober: The batter applicator handles both thin clear coatings and thick seasoned coatings with high viscosity. The over flow or submerger configurations can be selected to match your product specification. With separated products, we can ensure that each individual product gets an even coverage of batter.

Settling conveyor: During the transfer on the settling conveyor some batter are dripped of and collected for re-usage. During this transfer, the batter have time to settle before entering the first stage fryer.

Feeding

Fryer infeed belt: The infeed belt optimize the feeding of the singulated fries into the first fryer. The nose is adjustable to ensure the correct feeding into the oil.

Frying

Double frying system: The frying takes place in two steps. In Step 1, the coating is set and all products are fried separated. In Step 2, the fries, with a firm coating, will be stacked up as in a conventional fryer.
