Extrusion Technology

Heavy-Duty Wear Parts
High-chromium alloy and nitrided steel components are used for high-protein feed processing with reduced wear.

Modular Screw Design
Segmented profiles reconfigure precisely to optimize shear for various high-starch floating formulations.

Smart Heat Zones
PID barrel heating maintains stable temperature to reduce under-cooking risk.

Variable Speed Control
Adjustable frequency drives stabilize motor speed and reduce pressure fluctuation.

Uniform Pellet Extrusion
Optimized die geometry regulates melt flow to ensure consistent volumetric expansion.

Pellets Quality & Uniformity

Deep Oil Absorption
Vacuum coating introduces lipids into pellets to reduce surface stickiness.

Controlled Dehydration
Multi-stage conveyor belts reduce internal moisture differences to lower pellet breakage risk.

Extended Water Stability
Balanced cooking and drying locks the starch matrix, preventing pellet disintegration during immersion.

Clean Surface Finish
Post-coating cooling zones stabilize coating layer and reduce pellet clumping during packaging.

Thermal Nutrient Preservation
Low-temperature drying reduces protein denaturation and maintains structural stability.

FAQ

Q: Can this line handle high-fat formulations without clogging the extruder barrel?

A: Yes, the twin-screw design can handle up to 12% fat before external vacuum coating is needed.

Q: What is the average lead time for a customized 2-ton layout?

A: Manufacturing, assembly, and testing usually take 45–60 days after deposit confirmation.

Q: Can we produce both floating and sinking shrimp feed on this same line?

A: Sinking feed requires density control components and specific die configurations to limit expansion.

Q: How often do the screw segments need replacement during routine operation?

A: Depending on formula abrasiveness, high-chromium segments are usually replaced after 3,000–5,000 operating hours.
