Fiocchi di patate are a key ingredient in instant purè di patate, spuntini, and food manufacturing. A high-performance linea di produzione di fiocchi di patate requires more than just raw materials—it needs precision-engineered equipment at every step.
This guide introduces the 17 essential machines in a modern potato flakes processing line. Each piece of equipment is engineered for efficiency, hygiene, and consistent quality.
1. Vertical Washing Machine – Efficient Cleaning and Destoning
The vertical washer is the first line of defense against dirt and contamination.
Key Functions:
Washing chamber: A controlled cleaning cavity ensures deep washing of fresh potatoes.
Water flow control: Strong yet gentle jets remove soil and debris without damaging potatoes.
Destoning: By using gravity and density differences, stones are separated efficiently.
Automatic discharge: Clean potatoes are moved to the next step without manual intervention.
2. Horizontal Washing Machine – Secondary Cleaning & Impurity Removal
This stainless-steel machine enhances cleaning with spiral mechanisms and a circulation water system.
Highlights:
Integrates feeding, cleaning, impurity removal, and discharge.
Internal filters separate waste from water for a hygienic process.
Reduces manual cleaning needs and improves food-grade sanitation.
3. High-Efficiency Steam Peeling Machine – Fast Skin Separation
Designed for uniform, high-pressure steam treatment, this machine loosens potato skins for easy removal.
Caratteristiche:
Rotating drum design: Ensures even exposure to steam.
Automatic loading/unloading
Steam chamber control: Consistent temperature for ideal peeling without damaging pulp.
4. Potato Peeling Station – Brush-Based Skin Removal
After steam loosening, potatoes are fed into this station where rotating brushes strip off skins.
Benefits:
Stainless steel construction ensures durability and hygiene.
The waste discharge system sends skins directly to the disposal tanks.
Helical conveyor system for smooth material movement.
5. Sorting Platform – Manual Inspection for Quality Control
Before slicing, skilled workers manually inspect and sort potatoes on a conveyor table.
Purpose:
Remove rotten, deformed, or oversized pieces.
Guarantee consistent raw material quality for downstream processing.
6. Precision Slicer – Uniform Potato Slices for Better Flakes
The slicer cuts potatoes into consistent thin slices—key to texture and drying uniformity.
Caratteristiche:
Adjustable blade thickness
Low breakage rate
High output and automatic discharge
7. Blanching Machine – Starch & Sugar Removal, Microbial Control
Blanching is critical for starch removal and enzyme inactivation.
Key Specs:
Temperature range: 80–90°C
Steam-heated water bath ensures uniform blanching.
Spiral conveyor stirs and conveys slices for optimal processing.
8. Cooling Machine – Post-Blanching Temperature Control
Cooled slices retain color and texture before cooking.
System Components:
Circulating water bath
Spiral paddles for movement
Water temperature monitoring for oxidation control
9. Steam Cooking Machine – Final Softening for Mashing
Steam cooks the slices thoroughly for mashing.
Highlights:
Servo-controlled steam valves
Dual-screw spiral conveyor for even heat distribution
Real-time control of temperature, pressure, and feed rate
10. Potato mashing Machine – Smooth and Consistent Mashing
Cooked potatoes are mashed into a uniform paste.
Integrated with a steam cooker, the pulping machine ensures smooth delivery to the drying process.
11. Drum Dryer – Turning Potato Mash into Flakes
This is the core of potato flakes production.
Specifiche:
High-speed rotary drum with heated surface (150–170°C)
Thin-layer drying in seconds
Pneumatic blade scrapes off dried flakes
Fully PLC-controlled with touchscreen HMI
12. Primary Crusher – Breaking Dried Sheets into Flake Chunks
Connected to the drum dryer, it crushes the dried sheets into manageable flake sizes.
Pneumatic deflector prevents wet material from re-entering the system.
13. Cyclone Conveyor – Efficient Pneumatic Transport
Uses centrifugal airflow to move flakes from the crusher to the shaping or granulating system.
Advantages:
No moving parts → low maintenance
Sealed system → no dust, cleaner environment
14. Vibrating Sifter – Accurate Flake Size Separation
Sorts flakes based on shape and particle size.
Components:
Stainless steel frame
Multiple screen layers for precise grading
Seamless integration with a vacuum or cyclone feeder
15. Potato Flakes Grinder – Final Powder Grinding
Converts flakes into finer granules or powder.
Caratteristiche principali:
Adjustable grinding fineness
High-speed rotor system
Ensures product uniformity and purity
16. Weighing & Dosing Station – Precision Filling and Batch Control
Monitors and controls the quantity of final potato flakes or powder before packaging.
Benefits:
Reduces overfilling waste
Increases customer satisfaction
Ideal for integration with automated packaging lines
17. Vacuum or Heat Sealing Packaging System
Finishes the process with industrial-grade packaging.
Options include:
PE bag heat sealing
Outer bag stitching (PER ESEMPIO., jute or woven plastic)
Conveyor system to move sealed bags to storage or the palletizing zone
