COMPLETE PROCESS ROUTE

A continuous process from potato preparation to frozen finished product

Processing stages, critical controls, and equipment scope are organised around the target French fries specification, capacity, and site conditions.
01

Potato preparation

  1. 01

    Washing and peeling

    Wash and peel potatoes to prepare them for controlled cutting.

  2. 02

    Hydraulic strip cutting

    Cut potatoes to the required strip specification and prepare them for thermal treatment.

02

Thermal treatment and par-frying

  1. 01

    Blanching and cooling

    Blanch and cool the strips to support colour retention and starch control.

  2. 02

    Drying and par-frying

    Reduce surface moisture before par-frying to establish the target structure and colour.

03

Freezing and packaging

  1. 01

    IQF freezing and packaging

    Freeze products individually and connect to inspection, weighing, packaging, and storage.

KEY EQUIPMENT AND PROCESS CONDITIONS

Core equipment and process modules

The applicable equipment and process modules are shown in sequence to clarify how each stage connects and contributes to the line.
Continuous Blancher
BLANCHING MODULE

Continuous blanching equipment

Provides colour protection and starch treatment before frying.

  • 82 to 92 C; 2 to 5 minutes
Continuous Fryer
PAR-FRYING MODULE

Continuous frying equipment

Controls product setting and colour development during par-frying.

  • 165 to 180 C
IQF Tunnel Freezer
IQF FREEZING MODULE

IQF freezer

Freezes products individually before packaging and cold-chain handling.

  • Confirmed for the project

CRITICAL PROCESS CONTROLS

Key controls for stable French fries quality

01

Blanching conditions

Control blanching temperature and holding time so the fries receive the required colour protection and starch treatment without overcooking.

02

Surface dehydration

Set drying intensity and holding time to reduce free surface water before frying and maintain stable frying conditions.

03

Par-frying and freezing connection

Coordinate par-frying, cooling, and IQF feed rhythm to avoid sticking and maintain a stable finished-product structure.

CONFIGURATION DIRECTIONS

Configure modules around the product, throughput, and site conditions

Equipment quantities, interfaces, and layout can be planned around your project requirements.
CONFIGURATION 01

Standardized French fries production

A continuous process route for the target French fries specification.

CONFIGURATION 02

Flexible product changeover

Optional modules can be adjusted for raw-material condition and product dimensions.

CONFIGURATION 03

Customized line development

Configure the line around target capacity, plant interfaces, and available utilities.

CUSTOMIZED DESIGN AND MANUFACTURE

Site interface adaptation

Plan the layout around plant space, utilities, cold-chain, packaging, and storage conditions.

PROJECT DETAILS

Customer requirements, configuration approach, and results

The following anonymized case presents the requirements, project conditions, configuration path, and achieved results.
PROJECT EXAMPLE

Frozen French fries production project

A potato-products processor supplying foodservice and distribution channels.

Project requirements

  • Add continuous frozen par-fried French fries capacity for neighborhood retail, quick-service restaurants, and group catering.

Starting conditions

  • The previous semi-automatic process required substantial manual input, delivered inconsistent colour and a high short-strip rate, and could not reliably support batch orders.

Proposed solution

The project combined 500 kg/h brush washing and peeling, hydraulic strip cutting, washing, belt blanching, ice-water cooling, two-stage drying, continuous par-frying, de-oiling, IQF freezing, sorting, and packaging under centralized PLC control. The configuration was planned around available plant space, budget, and market requirements.

Project results

500 kg/hRaw-material handling capacity
<3%Short-strip rate
  • The line improved colour consistency and held the short-strip rate below 3%.
  • It supports small and medium production batches and multiple specifications.
  • The project is connected to local quick-service restaurant chains and regional distribution channels.
