(Cleaning & Peeling): Dry cleaning → Water rinsing → Peeling
(Inspection & Grading): Manual selection + Automatic grading
(Cutting & Sizing): Cutting into strips of various specifications as required (e.g., 10x10mm, 6x6mm)
(Blanching): A critical process for enzyme inactivation, color preservation, removal of reducing sugars, and starch pre-gelatinization
(Dewatering & Drying): Removing excess surface moisture to facilitate frying and achieve crispiness
(Frying): Setting color and shape, developing flavor
(De-oiling & Cooling): Removing excess oil and rapid cooling for shape setting
(Freezing): Rapidly passing through the ice crystal formation zone to maintain product quality (IQF - Individual Quick Freezing)
(Packaging & Metal Detection): Packaging by weight and detecting metal contaminants
(Cold Storage): Storage and transportation at -18°C or below
III. Investment and Configuration Plans (Scaled by Capacity)
Plan A: Small-Scale Production Line (Capacity: 200-500 kg/h)
Target Market: Local catering, specialty snack shops, startup brands.
Characteristics: Controllable investment, high flexibility, some processes can be handled manually.
Simplified Core Equipment:
Wahsing and Peeling: Small abrasive peeling machine.
Potato cutter machine : Semi-automatic or benchtop strip cutting machine.
Frying: Batch fryer with single or double tanks (non-continuous).
Freezing: Plate freezer or outsourced freezing.
Packaging: Semi-automatic vacuum packaging machine.
Advantage: Low startup capital, suitable for market testing.
Plan B: Medium-Scale Production Line (Capacity: 1-2 ton/h)
Target Market: Regional catering supply chains, large food processing plants, entry into supermarket channels.
Characteristics: Optimal cost-effective automation configuration, stable quality, high efficiency.
Core Equipment:
Raw Material Elevator: Evenly feeds potatoes into the production line.
Washing and Peeling Machine: Uses brush washers/peelers to remove peel and soil.
Manual Inspection Belt: Manual removal of sprouted or moldy potatoes.
Automatic French Fry Cutter: Efficient cutting, customizable cut sizes.
Dewatering and Drying: Thoroughly removes surface moisture, significantly reducing oil consumption during frying (notably lowers costs).
Fryer: Electric, gas, or thermal oil heated. Requires precise temperature control (typically 170-190°C). Includes automatic lifting and conveying systems with adjustable frying times.
Centrifugal De-oiler: Used immediately after frying; centrifugal force removes excess surface oil, effectively reducing product oil content to meet health demands.
Freezer: Rapidly cools products to -18°C or below, prevents clumping, and maintains optimal internal structure and crispiness upon reheating.
Packaging Machine: Uses vacuum packaging machines for weighing and packaging.
Advantage: Achieves continuous automated production from raw material to finished product, low unit cost, highly consistent quality, strong market competitiveness.
Plan C: Large-Scale Fully Automated Production Line (Capacity: 3-5+ ton/h)
Target Market: International brand OEM, national supply chains, export business.
Characteristics: High capacity, high efficiency, intelligent operation, low energy consumption.
Upgraded Core Equipment:
High-End Color Sorter: Replaces manual sorting; automatically rejects defective raw materials.
Intelligent Frying System: Includes heat recovery and precise oil filtration.
High-Efficiency IQF Fluidized Bed Freezer: Higher freezing efficiency.
Robotic Palletizing System: Fully automatic palletizing and boxing.
MES (Manufacturing Execution System): Integrates PLC and SCADA systems for production data monitoring, equipment alerts, quality traceability, and energy management.
Advantage: Economies of scale deliver ultimate cost advantage; intelligent management ensures quality; possesses international competitiveness.
