Rice Noodle Production Process: Double-Barrel Twin-Screw Self-Cooking Technology
In industrial rice noodle production, process stability and product consistency are far more important than recipe adjustments alone.
Among modern rice noodle manufacturing technologies, double-barrel twin-screw self-cooking extrusion has become one of the most reliable and widely adopted solutions for export-oriented production lines.
What Is Double-Barrel Twin-Screw Self-Cooking Technology?
Double-barrel twin-screw self-cooking technology uses two connected extrusion barrels, each with a specific function, to complete:
Rapid cooking (gelatinization) of rice dough
Stable extrusion and noodle forming
The cooking process is achieved inside the extruder itself, without external steaming systems, through mechanical pressure, shear force, and frictional heat.
Core Process Logic: Separate Cooking and Forming for Maximum Stability
Unlike single-barrel extrusion, the double-barrel design allows independent control of cooking and forming, which is the key to consistent rice noodle quality.
Raw Dough Barrel: High-Speed Extrusion for Rapid Cooking
The raw dough barrel is the first and most critical stage of the process. Its main functions include:
High-speed twin-screw conveying
Strong compression and shear
Rapid temperature rise inside the barrel
Under these conditions, the rice dough quickly undergoes:
Starch gelatinization
Structural formation of the dough
Initial plasticity development
Technical Advantages of the Raw Dough Barrel
Fast and uniform cooking
No external steam or boiler required
Stable gelatinization level
Reduced energy loss
This ensures that the dough entering the next stage is fully and evenly cooked.
Cooked Dough Barrel: Lower Speed Extrusion for Stable Noodle Forming
After cooking, the dough enters the cooked dough barrel, where the screw speed is slightly reduced.
The main purpose of this barrel is not cooking, but controlled extrusion and noodle discharge.
Key functions include:
Stabilizing extrusion pressure
Maintaining dough structure
Ensuring continuous and uniform noodle output
Technical Advantages of the Cooked Dough Barrel
Smooth and continuous noodle extrusion
Uniform thickness and straightness
Reduced breakage rate
Ideal for long rice noodles and rice vermicelli
This stage determines the final appearance and consistency of the product.
Why Double-Barrel Technology Is Better Than Single-Barrel Extrusion
| Comparison Item | Double-Barrel Twin-Screw | Single-Barrel Extrusion |
|---|---|---|
| Cooking Control | Precise, segmented | Difficult to stabilize |
| Noodle Forming | Very stable | Easy to break |
| Process Flexibility | High | Limited |
| Production Scale | Medium to large | Small-scale |
