French Fries Production Line
We have extensive knowledge of the potato as raw material and how to design an effective process. We combine the latest technologies using computer simulation programs and build efficient and reliable process equipment. We take full responsibility for design, manufacture and installation. Supplier will commission the line and make sure that your staff gets professional training in process control and maintenance.
Process for French Fries Production
Step 1: Preparation
As potatoes are received, they are sorted, and pre-graded to correspond with the type of French fry to be produced. Potatoes then enter the line and pass through the destoner and washing process, before being peeled.
Steam Peeling & Inspection
After steam peeling, the deskinner removes and collects the peel waste, and the potatoes are then washed clean prior to being inspected and transported to the cutting process.
Step 3: Cutting
The cutting process is performed by either a hydro-cutting or mechanical cutting system. These machines cut the potato into strips-crinkled or straight, to the desired size, and then pass the strips through equipment that removes slivers and nubbins.
Step 4: Blanching
The potato strips then pass through a blanching system, consisting of two or more screw blanchers. Here the strips are gelatinized and the sugar levels reduced, then they go through the SAPP-dipping belt, before being pre-dried.
Step 5: Drying
During the drying process (which is optional for smaller lines), the moisture content is reduced, and the strips are now ready for the frying process, where the final texture and colour is achieved. Before entering the fryer the French fries are transported on the Equilibration belt to get an even moisture content.
Step 6: Multi Zone Frying
With controlled oil flows together with Multi-Zone design and the belt return outside the fryer, Rosenqvists frying system will give you the best tools to achieve the desired texture and colour. After frying, the French fries will pass a defatting step. For coated fries and other potato products, a batter and pre-frying step is added before the normal frying system.
Step 7: Freezing & Packing
After the defatting step the golden French fries
will enter the freezer, on their way to the packaging
system. The line can also be equipped
with a pre- cooler installed before the freezer.
