Features

Advanced Twin-Screw Mixing

Twin-screw design repeatedly shears and folds material, producing uniform mixing far beyond single-screw machines.

Material Adaptability

Processes high-moisture (>30%), high-fat (>15%), and high-fiber ingredients reliably for diverse snack formulations.

Precise Temperature Control

Segmented barrel heating maintains exact process temperatures, supporting low-temperature sterilization or high-temperature puffing.

Basic Structure And Working Principle

Main components
Transmission system: motor, reduction gearbox, driving the twin screws to rotate.
Feeding system: precisely controlling material input (such as screw feeder, liquid injection pump).
Extrusion system
Barrel: segmented heating/cooling, modular combination.
Twin screw: rotating in the same or opposite direction, can be combined with different screw elements (conveying, shearing, mixing, etc.).
Die head system: determines the final shape of the product (such as puffed food, pellet feed).
Cutting system: rotating blades adjust the length of the product (such as pet food, snacks).
Working process
Feeding section: material (powder, slurry, etc.) is fed into the barrel.
Conveying and mixing section: the screw rotates to push the material forward, while shearing and mixing.
Melting and reaction section: under high temperature and high pressure, the material undergoes gelatinization, denaturation or chemical reaction (such as starch gelatinization, protein cross-linking).
Molding: The molten material is extruded through the die, where a sudden drop in pressure causes it to expand (e.g., in puffed foods). Cutting and Cooling: The product is cut and cooled to set its shape.

FAQ

Q: How does the machine handle high-fat or high-fiber ingredients?

A: The twin-screw design provides strong shear and folding, ensuring uniform mixing and smooth extrusion even for high-fat (>15%) or high-fiber materials.

Q: How is temperature controlled during extrusion?

A: Barrel temperature is segmented and precisely regulated via PLC, accommodating processes from low-temperature sterilization to high-temperature puffing.

Q: Can the machine produce different shapes and textures?

A: Yes, changing screw elements and dies allows production of various shapes, textures, and density levels according to product requirements.

Q: What maintenance is required for long-term operation?

A: Routine cleaning, lubrication of moving parts, and periodic inspection of screws and barrel ensure stable performance. Our manual provides detailed schedules.
