Automatic Fish Feed Processing Line

The Automatic Fish Feed Processing Line from Darin Machinery is designed for high-volume aquaculture feed production. Its capacity depends on the model.

Per Hour: 1–10 tons/hour (Model DR-FF1+)

Per Day: 8–80 tons/day (based on 8-hour shift)

Key Variables That Affect Output:

• Pellet Size & Shape: Smaller or simpler pellets yield higher output.

• Recipe & Formulation: Moisture and raw material composition affect extrusion speed.

• Grinding & Extrusion Efficiency: Ultra-fine grinding and triple-shaft extrusion impact throughput.

• Operator Skill & Line Setup: Well-trained operators and optimized settings maximize daily output.

If you need higher capacity, Darin can customize the line with larger extruders or faster drying and cooling systems.

The Automatic Fish Feed Processing Line handles flexible pellet sizes. Suitable for all fish species and growth stages. Here are typical specs:

✅ Minimum Pellet Size:

Diameter: ~0.5 mm
Length: ~1 mm

Ideal for fish fry and small fingerlings. Easy ingestion and digestibility.

✅ Maximum Pellet Size:

Diameter: ~10 mm
Length: ~15 mm

For larger fish species. Longer feeding time. Superior floating stability.

⚙️ Customization Notes:

We can customize pellet sizes beyond these ranges.
The extruder die and grinding system must match your chosen size.
For non-standard shapes (slow-sinking, extruded sticks), Darin can adjust extruder tooling.

Would you like size recommendations based on your target fish species and market?

Yes. This line is designed for flexible formulation production. It handles multiple recipes and ingredient combinations.

✅ How It Works:

Automatic Batching System:
Different formulations are precisely weighed and dosed. Supports multiple recipes.

Mixing System:
Blends ingredients uniformly for consistent nutrient distribution.

Ultra-fine Grinding System:
Achieves fine powder for superior gelatinization. Different recipes can be processed.

Triple-Shaft Twin-Screw Extruder:
Cooks and shapes pellets with precise control. Different formulations run sequentially.

The Automatic Fish Feed Processing Line requires significant installation space due to its large-scale, multi-component structure. Below is a detailed overview of the total footprint and installation space required:

📐 Standard Line Footprint:

🧩 Recommended Installation Space:

To ensure safe operation, maintenance access, and material flow, we recommend allocating:

Minimum required space: ≥ 55 m (L) × 12 m (W) × 6.0 m (H)
Preferred space with buffer zones: 65 m × 15 m (ideal for raw material silos, product storage, and auxiliary systems)

⚙️ Considerations:

Silo and raw material storage areas require additional space
Space can be adjusted for L-shaped or U-shaped layouts
A modular design allows partial reconfiguration based on workshop constraints
Additional space for packaging equipment and warehouse storage
