Why Twin-Screw Extrusion?
Transform Simple Grains into
Transform Simple Grains into
High-Value Products.
Traditional food processing often requires separate machines for mixing, cooking, kneading, and shearing. Loyal’s Twin-Screw Extrusion Technology combines all these steps into a single, continuous process.
Utilizing HTST (High-Temperature Short-Time) cooking, our extruders process raw ingredients (corn, rice, wheat, soy) within seconds. This preserves essential nutrients, destroys anti-nutritional factors, and creates diverse textures—from the crispiness of a corn flake to the chewiness of plant-based meat.
-
Versatility: Process a wide range of raw materials including flour, starch, protein powder, and fresh slurry.
-
Efficiency: Cook and form in one step, reducing energy consumption and floor space compared to traditional batch cooking.
-
Product Diversity: Switch from producing puffed snacks to nutritional rice simply by changing the screw profile and die mold.

See Line DetailsThe Modular Process: One Core, Many Paths
From snacks to proteins, the core extrusion technology remains the same. The downstream equipment defines the final product.
Preparation
Mixing & Conditioning
Raw materials (corn flour, rice powder, soy meal) are mixed with water and oil. For high-grade products, a Pre-Conditioner steam-cooks the mix before extrusion.
Hydration & Mixing
Universal Core
Twin-Screw Extrusion
The heart of the line. High temperature, high shear, and pressure cook the ingredients. Change the Screw Profile to switch from high-expansion puffing to dense texturization.
LY Series Extruder

Core Extrusion Technologies
Precision & Adaptability
The secret to producing both puffy snacks and fibrous meat analogues on the same platform lies in our modular engineering.
Modular Screw Design
The screw is not a single piece. It is assembled from interchangeable segments (Shear Blocks, Kneading Blocks). By rearranging these blocks, you can alter the pressure and shear force to suit different recipes.
Material
38CrMoAl / Alloy
Hardness
HRC 58-62
Multi-Zone PID Control
Food products require precise thermal curves. Our barrel is divided into 3-5 independent temperature zones, each controlled by a PID System with water cooling and electric heating for ±1°C accuracy.
Control Type
PID Auto-Tune
Accuracy
± 1°C
High-Torque Gearbox
The engine room of the extruder. We use customized gearboxes with NSK/SKF Bearings and forced oil lubrication. Designed to withstand the high back-pressure required for texturized vegetable protein (TVP).
Bearings
NSK / SKF
Lubrication
Forced Oil Cool
Interchangeable Screw Elements
Versatility isn’t magic; it’s engineering. By simply changing the sequence of the screw elements, you can transform your machine from a high-shear Corn Puff Extruder into a low-shear, high-pressure Rice Extruder. Loyal engineers provide the custom configuration map for your specific product recipe.

Frequently Asked Questions
Common questions about versatility, capacity, and machinery maintenance.
Can I make Puff Snacks and Corn Flakes on the same line?
Partially. The core Twin-Screw Extruder is the same for both. However, the downstream equipment differs significantly. Corn Flakes require a Flaking Machine, High-Temp Roaster, and Sugar Coating Drum, while simple Puff Snacks only need a standard dryer and flavoring drum. We recommend dedicated lines for high efficiency, but a combined line is possible with modular add-ons.
Why use a Twin-Screw Extruder instead of Single-Screw?
Twin-Screw extruders offer superior mixing capability and process stability. They can handle a wider range of raw materials (high moisture, high fat, fine powders) without clogging. Plus, they have a Self-Cleaning function, saving hours of maintenance time during recipe changes.
What happens if the screw wears out? Do I replace the whole thing?
No. Our screws feature a Modular Segment Design. If a specific section (usually the high-wear zone near the die) wears out, you only need to replace those specific segments, not the entire screw shaft. This significantly reduces long-term maintenance costs.
What energy sources can I use for the dryer?
Our multi-layer dryers can be customized for Electricity, Natural Gas, LPG, Diesel, or Steam. Gas and Steam are generally more cost-effective for large-capacity industrial lines (>500kg/h), while Electricity is suitable for smaller pilot lines.
Do you provide food recipes?
Yes. We provide basic formulas for all standard applications (Corn Curls, TVP, FRK Rice, etc.) during installation. Our engineers will help you adjust the recipe on-site to match your local raw material characteristics and taste preferences.
