1T/H Twin Screw Fish Feed Extruder in Turkey

Why the SPHS75x2 Twin Screw Fish Feed Extruder Was the Smart Fit

The twin screw fish feed extruder in Turkey was perfectly sized for a family-run trout farm that needed steady daily output but couldn’t justify overspending. The twin screw design also ensured the farm could handle recipes with high protein (trout starter feed often reaches 42–48% protein) and adjust sinking rates to match trout feeding habits.

Local Raw Materials: Balancing Nutrition and Cost

• Fish meal: 35% (partly from local Black Sea fisheries)
• Soybean meal: 20% (mostly imported)
• Wheat flour: 20% (Turkish wheat, easy to source)
• Corn gluten meal: 15% (adds digestible protein)
• Fish oil: 5% (mainly for essential fatty acids)
• Vitamin and mineral premix: 5%

Before installing the floating fish feed extruder, the farmer mixed these raw materials in a basic vertical mixer. Now, the pre-conditioned mix goes into the twin screw extruder, where the steam and differential conditioners ensure proper gelatinization. This helps produce uniform, slow-sinking pellets perfect for trout tanks and raceways.

Small Steps, Big Changes: How the Twin Screw Extruder Helped

Before buying the fish feed extruder, the farm spent about 80% of its variable costs on outsourced starter and grower feed. With the new extruder, they can produce 60–70% of their annual feed needs in-house and only buy specialized finishing feed or supplements from larger suppliers when needed.

• Better pellet durability: The twin screw system ensures strong bonding and a consistent slow-sinking rate, ideal for trout who feed mid-column
• Custom pellet sizes: The farmer can switch die sizes for fry, fingerlings, or growers, instead of relying on standard off-the-shelf products
• More stable water quality: Uniform pellets mean less feed waste and less pond fouling — especially critical for raceway systems in the Black Sea region

Trout Feed and More: Expanding Future Possibilities

For now, the farmer uses the floating fish feed extruder mainly for rainbow trout feed. But he’s already testing small batches for other species, like carp and even ornamental koi. In Turkey, koi farming is still niche but growing slowly as wealthier urban families set up garden ponds.

If the koi feed tests succeed, the farm may use the same fish feed pelletizer to produce small runs of ornamental feed, adding a new revenue stream. The flexibility of the twin screw design makes it easy to adjust the oil content and expansion level for different species.

No Full Feed Line? No Problem.

This project shows that small Turkish fish farmers don’t always need to invest in a huge feed mill all at once. By starting with a single twin screw fish feed extruder, they can tackle the most sensitive part of feed production: extrusion.

The farm continues to use its old hammer mill and vertical mixer for raw material prep. By focusing investment on extrusion, they made the biggest quality leap with the smallest risk.

This staged approach is increasingly popular in Turkey’s aquaculture sector. It gives farmers more control, reduces feed supply chain shocks, and opens the door to future upgrades — like adding a small bagging line or better ingredient silos down the road.

Reliable Capacity, Local Support, Real Returns

• Lower feed costs: The farm saves about 12% per kilo compared to buying bagged feed
• Higher fish survival: More digestible, uniform pellets mean healthier fry with higher survival rates
• Faster growth: The farmer can tweak recipes seasonally to boost protein or oil levels for maximum weight gain

RICHI MACHINERY provided on-site installation support and training, so the family didn’t have to hire extra technicians or production engineers. This was key to making the machine profitable fast.

The Future: Turning Trout Into Profits, One Pellet at a Time

Turkey’s trout sector keeps expanding as more farmers discover the value of making feed in-house. The secret is starting small and smart — like this farm did — with a robust floating fish feed extruder machine that handles high-protein trout feed and leaves room to experiment with other species.

As the farm grows, they plan to add a small dryer and bagging unit. But they know the twin screw fish feed extruder machine is the core — it guarantees stable pellet quality, digestibility, and profit margins in a market where cost control is everything.

Why This Trout Farmer Chose RICHI MACHINERY

• Practical scale: The SPHS75x2 fish feed pelletizer is powerful enough for daily farm use but small enough for easy maintenance
• Proven local references: Other Turkish farms already run RICHI twin screw extruders with local ingredients
• Service: RICHI’s technical team provided full support — from helping design the steam lines to training farm staff to run and maintain the equipment safely

Ready to Feed Your Fish Smarter?

If you run a trout farm — or any aquaculture operation — in Turkey or anywhere in the region, it might be time to rethink your feed supply chain. You don’t have to build a giant feed mill overnight. A single floating fish feed extruder, fish feed pelletizer, or fish feed extruder machine can change everything.

RICHI MACHINERY is ready to help you step up your feed game, cut your costs, and grow healthier fish — all with equipment sized to match your real-world needs.
