Noodle texture
Cooking performance
Final product consistency
Dough Mixing Process
The dough mixer combines flour and water evenly to form dough granules.
The mixing process helps:
Hydrate flour particles
Develop gluten structure
Improve dough elasticity
Ensure stable noodle texture
Most industrial mixers operate continuously to support large-scale production demands.
Some premium production lines use vacuum mixers to improve noodle density and surface smoothness.
Resting the Dough
After mixing, the dough enters the aging process.
Dough aging allows:
Moisture distribution
Gluten relaxation
Improved dough uniformity
This stage enhances dough flexibility and helps produce smoother noodle sheets.
Without proper dough aging, noodles may become brittle or uneven during processing.
Compound Rolling System
The dough then passes through multiple rolling machines that gradually compress it into thin sheets.
The rolling process:
Aligns gluten fibers
Removes air pockets
Improves dough density
Creates uniform thickness
Multi-stage rolling is critical for maintaining consistent noodle quality.
Thickness Adjustment
Operators can adjust roller gaps based on noodle specifications.
Different noodle styles require different thickness levels, such as:
Thin ramen noodles
Thick instant noodles
Flat noodles
Wavy noodles
Automatic thickness control systems improve production precision.
Noodle Cutting
After sheeting, the dough passes through noodle slitting machines.
Cutting blades shape the noodle strands according to product requirements.
The slitting system ensures:
Uniform noodle width
Consistent strand size
Smooth noodle edges
Waving Process
Most instant noodles have a wavy shape.
The waving machine creates noodle curls by adjusting conveyor speed differences.
Wavy noodles offer several advantages:
Better packaging efficiency
Faster cooking
Improved soup absorption
Attractive appearance
The waving process is a key feature in instant noodle manufacturing.
Gelatinization Process
After shaping, noodles enter the steaming machine.
Steaming partially cooks the noodles by gelatinizing the starch.
This process:
Sets the noodle structure
Improves texture
Enhances elasticity
Reduces cooking time for consumers
Steam temperature and steaming time must be controlled carefully.
Improper steaming may result in:
Poor texture
Fragile noodles
Uneven cooking performance
Forming Noodle Blocks
After steaming, the noodle strands are cut into fixed lengths and folded into noodle blocks.
The noodle blocks are shaped according to packaging type:
Square blocks
Round bowl noodles
Cup noodle portions
Automatic cutters ensure consistent block size and weight.
This stage determines whether the instant noodles are fried or non-fried.
Fried Instant Noodle Production
Deep Frying Process
In fried instant noodle production lines, noodle blocks enter a continuous frying machine.
The frying process:
Removes moisture rapidly
Creates porous noodle structure
Extends shelf life
Enables quick rehydration
Typical frying temperatures range between 140°C and 160°C.
Frying usually lasts 1–2 minutes depending on noodle type.
Benefits of Fried Noodles
Fried noodles provide:
Fast cooking time
Strong flavor absorption
Long shelf life
Crispy texture before cooking
Fried instant noodles remain highly popular worldwide.
Hot Air Drying Technology
Health-conscious markets increasingly prefer non-fried instant noodles.
Instead of frying, noodle blocks enter a hot air drying system.
Drying removes moisture gradually while preserving noodle structure.
Benefits include:
Lower oil content
Healthier product positioning
Reduced fat levels
