Fish Feed Extruder – Floating Aquatic Feed Processing Equipment (160-315kW, 3-10t/h)

1. Equipment Overview

The SYPH series fish feed extruder is a high-performance, industrial-scale processing machine specifically engineered for the production of floating aquatic feed. Covering a power range of 160–315 kW and delivering processing capacities from 3 to 10 t/h, this equipment is designed to meet the demanding requirements of commercial aquafeed production for various fish and shrimp species.

Adopting an advanced wet extrusion process with precise control over moisture, steam, and ingredient mixing, the SPH series ensures superior pellet quality, high water stability, and excellent floating characteristics, making it the ideal choice for aquaculture feed manufacturers seeking consistent, high-quality output.

2. Core Product Advantages

1. Optimized for Floating Aquatic Feed Production
The molding process is specifically designed for all types of floating aquatic feed, producing pellets with uniform shape, smooth surface, and excellent water stability, ensuring minimal nutrient leaching and maximum feed utilization.

2. Superior Pellet Uniformity & Stability
The extruder delivers particles with consistent size, density, and texture, ensuring uniform expansion and stable floating performance across all production batches.

3. Advanced PLC Control System
Equipped with a sophisticated PLC system, the machine achieves precise, real-time control over water addition, steam injection, and feed formulation ratios. This ensures perfect extrusion conditions at every stage, guaranteeing repeatable product quality and operational efficiency.

4. Ultra Wear-Resistant Components for Extended Service Life
Core wearing parts are manufactured from premium abrasion-resistant alloy steel using specialized processing technology. Their service life exceeds that of conventional materials by more than 5 times, significantly reducing maintenance frequency, replacement costs, and production downtime.

5. Jacketed Barrel for Precise Temperature Control
The outer barrel is equipped with a jacketed design that allows direct injection of steam (for heating) or cold water (for cooling) into different extrusion zones. This enables precise temperature management along the barrel, optimizing gelatinization and extrusion performance for a wide range of formulations.

6. Anti-Bridging Design for Uniform Feeding
The feeding system incorporates a variable-pitch screw that effectively eliminates material bridging, caking, and blockages, ensuring continuous, homogeneous, and stable material flow for consistent production output.

7. Variable-Frequency Drive for Precise Feed Control
Equipped with an advanced inverter-driven feeder, the extruder offers simple operation and highly accurate feed volume adjustment. Real-time control allows seamless synchronization with production demands, adapting to varying throughput requirements while delivering notable energy savings.

8. Imported Bearings with Active Lubrication & Cooling
Core transmission components are fitted with original imported NSK precision bearings, supported by a dedicated oil lubrication and cooling system. This active thermal management extends bearing service life by 3 to 5 times compared to standard bearings, ensuring reliable performance under sustained high-load, continuous operation.

3. Application Scope

The SYPH series fish feed extruder is ideally suited for the production of floating aquatic feed for:

• Fish species: Tilapia, catfish, salmon, trout, sea bass, carp, and other commercial freshwater and marine fish

• Shrimp and crustaceans: Various shrimp and prawn species

• Feed types: Starter, grower, and finisher diets, as well as specialized floating pellets for different life stages and species

It is widely adopted by large-scale aquafeed mills and commercial aquaculture operations seeking high-capacity, reliable extrusion solutions.
