Wet-Type Single-Screw Floating Fish Feed Extruder Installed in Iraq: Project Case Study

1. The Challenge: High Import Costs in the Iraqi Aquaculture Market

Fish farming (specifically Tilapia, Carp, and Catfish) is a booming sector in Iraq. However, many commercial farms struggle with the high cost of imported floating pellets. Our client, a medium-sized fish farm owner in Iraq, faced three major challenges:

1. High Operational Costs: Imported feed accounted for over 70% of total production expenses.

2. Inconsistent Quality: Delayed shipments often led to stale feed with reduced nutritional value.

3. Climate Constraints: Equipment needed to operate reliably under Iraq's high ambient temperatures.

To solve this, they sought a cost-effective, durable, and easy-to-operate on-site feed production solution.

2. The Solution: Why the Wet-type single screw floating fish feed pellet extruder machine?

After evaluating several options, the client selected the MIKIM Wet-type single screw floating fish feed making machine. Here is the professional rationale behind this choice:

Wet-type floating fish food extruder machine vs. Dry-type floating fish food pellet making machine

For a commercial farm, the "Wet Process" is superior. By using a steam conditioner, the raw materials are pre-cooked. This results in:

• Superior Floating Performance: Pellets stay buoyant for over 12-24 hours.

• Improved Digestibility: High starch gelatinization (above 85%) makes nutrients easier for fish to absorb.

• Machine Longevity: Steam reduces friction in the barrel, extending the lifespan of the screw and die by 30%.

Single-screw fish feed making machine vs. Twin screw floating fish food maker machine

While Twin screw floating fish feed pellet maker machines are high-end, the Single-screw solution was the most strategic for this project because:

• Faster ROI: Lower initial investment for a 150-200 kg/h capacity.

• Simplicity: Easier for local staff to operate and maintain without specialized engineering backgrounds.

3. The Challenge of Feed Preservation in Iraq

While the extrusion quality was a priority, the client highlighted a critical concern: Storage Stability.

In Iraq's fluctuating climate, pellets with residual moisture quickly degrade. To solve this, the project required not just a high-performance extruder, but a precision-engineered drying solution that could handle the 200kg/h output while fitting within a specific facility footprint.

4. Optimized Equipment Configuration

The production line was customized to ensure a seamless flow from raw materials to bagged products.

5. Why the 5×5m Drying Oven was the Strategic Choice

A standout feature of this Iraqi project is the inclusion of the 5×5 meter drying chamber. Our engineering team recommended this specific configuration over a traditional multi-layer belt dryer for several expert reasons:

A. Optimized Drying Footprint

The 5×5m dimensions provide a massive 25 square meters of drying surface area. For a 150-200 kg/h line, this allows the pellets to be spread at an optimal thickness, ensuring that heat penetrates every pellet evenly without mechanical damage.

B. Precise Temperature Control for Nutrient Retention

Fish feed is sensitive to high heat. The 5×5m oven utilizes a specialized airflow system that maintains a constant temperature. This removes moisture from the core of the pellet (crucial for "floating" stability) without scorching the protein-rich surface.

C. Energy Efficiency in Hot Climates

In Iraq, ambient temperatures are high. The 5×5m oven is fully insulated, capturing local heat and requiring less supplemental energy to reach the target drying temperature, significantly lowering daily OPEX (Operating Expenses).

6. Real-World Performance: Results from the Field

Since commissioning, the Iraqi customer has reported excellent operational metrics:

• Production Stability: The machine operates continuously for 8-10 hour shifts without blockage.

• Pellet Quality: The pellets feature a smooth surface and high structural integrity, reducing water pollution in the ponds.

• Cost Savings: By utilizing local rice bran and corn, the cost per ton of feed has dropped by approximately 35-40% compared to international brands.

7. Project Results & Client ROI

• Floating Performance: 99% of pellets remain buoyant for over 12 hours.

• Operational Cost: By moving from imported feed to this on-site 200kg/h line, the client reduced feed costs by $180 - $250 per ton.

• Durability: The 5×5m oven’s simple mechanical structure (fewer moving parts than a belt dryer) means significantly lower maintenance costs in remote Iraqi farming regions.

8. Expert Maintenance Tips for Hot Climates 

Based on our engineering experience in the Middle East, we recommend the following for machines operating in Iraq:

1. Heat Management: Ensure the extruder is placed in a well-ventilated area to protect the motor from overheating during summer.

2. Steam Consistency: Maintain stable boiler pressure to ensure uniform pellet expansion.

3. Daily Cleaning: Always clear the die holes after production to prevent "caking" due to high protein residues.

9. FAQ

Q: Why use a 5×5m oven instead of a continuous belt dryer?

A: For capacities around 200kg/h, a 5×5m oven offers a better ROI. It provides more control over "residence time" (how long the feed dries), which is vital for specialized fish feed formulas that r
