Frozen French fries rank among the world’s most popular fast food items. With the continuous expansion of fast-food chains and the catering industry, an increasing number of food processing enterprises are investing in automated frozen French fry production lines.
So, what core equipment comprises a complete frozen French fry production line? And how do these components work together?
Brush Washing and Peeling Machine
This is the first step in the entire production line, designed to remove dirt and impurities from the potato surface while completing the peeling process.
Function: combines washing and peeling into one operation.
Features: brush roller design ensures even peeling without damaging the potato flesh.
The performance of this equipment directly determines the quality of subsequent cutting and frying processes, making it the foundational component of the entire system.
Potato Cutting Machine
Washed and peeled potatoes are fed into the cutting machine, where they are sliced into French fries of various specifications (6mm, 9mm, 12mm, etc.) according to requirements.
Features: interchangeable blades, adjustable dimensions.
Advantages: automatic feeding, uniform cutting, and reduced material waste.
Cutting quality directly impacts the consistency of French fry shapes and frying times.
Blanching Machine
Blanching is one of the key steps in French fry processing.
Function: removes starch and sets color through blanching with hot water or steam.
Effect: preserves the golden color and crisp texture of French fries.
Temperature Control: Typically between 85–90°C, for approximately 1–2 minutes.
Dewatering Machine
After blanching, French fries retain excess surface moisture that must be removed via centrifugal or air-drying methods.
Purpose: prevent oil temperature fluctuations and excessive oil consumption during frying.
Advantages: enhances frying efficiency and ensures consistent product texture.
Frying Machine
Frying is the critical step that determines the flavor of French fries.
Equipment type: electric heating or gas heating
Temperature Range: 160–180°C
Features:
- Automatic temperature control
- Oil residue separation system
- Energy-efficient design for extended oil lifespan
A high-quality frying system ensures French fries are crispy on the outside, tender on the inside, and evenly golden in color.
Cooling Conveyor
Fried french fries require rapid cooling to prepare for the freezing process.
Function: reduces hot steam and prevents fries from sticking together.
Features: stainless steel mesh belt design ensures uniform ventilation.
Freezer
The final step is quick-freezing treatment.
Temperature: typically -35°C to -40°C
Time: 10–20 minutes to achieve Individual Quick Freezing
Result: preserves french fry shape and texture, facilitating storage and transportation.
Conclusion
The modern frozen French fries production line achieves fully automated control from washing to packaging, requiring only 3–4 workers to operate the entire line.
We offer configurations ranging from 300kg/h to 2000kg/h output, supporting CE/ISO certification, international voltage customization, on-site installation, and training.
