As the global appetite for frozen french fries continues to rise, food manufacturers are investing in automated french fries processing machines to increase efficiency and consistency.
From small snack factories to large frozen food plants, automation is key to meeting quality standards and reducing labor costs.
So how does a french fries processing machine actually turn raw potatoes into crispy fries?
How the French Fries Processing Machine Works
- Washing and Peeling – Preparing Clean Potatoes
The process starts with a potato washing and peeling machine, which uses brushes and water spray to remove mud and skin.
This ensures each potato is clean and smooth, ready for the next cutting stage.
- Cutting – Forming Perfect Strips
Next, the potatoes move into the french fries cutting machine, where high-speed blades slice them into even strips (usually 7–10 mm thick).
Consistent size is critical for uniform frying and better texture.
- Blanching and Cooling – Enhancing Color and Texture
Blanching machines briefly cook the fries in hot water (around 85–90°C) to remove excess starch.
Then, a cooling conveyor lowers their temperature to lock in the natural yellow color and firm texture.
- Dewatering and Frying – Building Crispy Flavor
After drying, the fries enter the continuous frying machine, a core component of the french fries processing line.
Oil is precisely controlled at 170–180°C, giving fries their crispy golden surface and delicious flavor.
Automatic oil filtering and temperature control help reduce oil consumption and maintain consistent results.
- Freezing and Packaging – Preserving Freshness
Fried fries are quickly frozen in an IQF freezer at -35°C, preserving their taste and preventing clumping.
Finally, the automatic packaging machine measures, fills, and seals bags for long-term cold storage and export.
