5–6 T/H Large Fish Feed Extruder in Australia

Why This Farm Chose a Standalone Twin Screw Extruder

Instead of immediately investing in an entire feed mill, the farm made a strategic decision: they would first acquire a high-capacity twin screw fish feed extruder machine and integrate it with their existing small hammer mill, mixer machine, and storage silos.

This step-by-step expansion reduces upfront risk while giving them full control over the final stage of production — the extrusion that determines pellet quality, buoyancy, and water stability.

After months of research and consultation, the farm settled on the RICHI SPHS150×2 twin screw floating fish feed machine, configured to run at up to 6 tons per hour, enough to cover their current annual fish feed needs and supply a few neighboring farms as well.

The Selected Model and Key Specs

This size hits the sweet spot for a mid-sized operation like theirs — big enough to process multiple fish species at scale, but still practical to manage with a small technical team.

What Raw Materials Are They Using?

• Wheat and barley (domestic): 40%
• Canola meal (local crush): 15%
• Fish meal (Australian or New Zealand origin): 25%
• Poultry by-product meal: 10%
• Fish oil (from local fish processing plants): 5%
• Premix (vitamins and minerals): 5%

The large fish feed extruder in Australia handles this recipe efficiently, ensuring full cooking and stable pellet formation for floating behavior.

Product Focus: Barramundi, Prawns, and More

The core goal of adding this large fish feed extruder is to produce premium floating feed for barramundi — one of Australia’s most popular warm-water farmed fish.

Thanks to the flexibility of the twin screw design, the machine can also handle feed for prawns during certain seasons. The extruder’s stable temperature and pressure control make it possible to switch between formulations without sacrificing pellet quality.

In the future, the farm plans to test recipes for ornamental koi feed and small trial runs of high-protein pellets for tropical aquarium fish, opening doors to niche markets.

Replacing Old Problems With Reliable In-House Production

• Precise control over pellet size: from fry starter feed to grower and finisher rations
• Better water stability: reduced fines and breakage keep ponds cleaner
• More consistent nutrient profiles: no nutrient loss due to long shipping or poor storage conditions

Why a Standalone Machine, Not a Full Line?

A full fish feed production line requires a significant upfront investment, more space, and a bigger technical team. For this operation, buying the single large fish feed extruder machine lets them test the waters with local production.

Their existing hammer mill, mixer, and weighing systems handle raw material prep just fine. This means their new investment focuses purely on what they could not do before — producing high-quality floating pellets at scale.

Reliable After-Sales Support: A Deciding Factor

One big reason the farm chose RICHI over local alternatives was confidence in overseas after-sales support. The farm’s operations manager explained that this purchase wasn’t just about buying an extruder — it was about gaining access to a partner with technical know-how, parts supply, and a willingness to help optimize formulations.

RICHI’s experts provided detailed training on how to:

• Adjust moisture and temperature profiles
• Switch between different species formulas
• Manage preventive maintenance to minimize downtime

This ongoing connection makes a big difference in a place like Australia, where on-site technical help for extruders isn’t always easy to find.

Early Results: Strong ROI and New Opportunities

• Feed cost per ton: down by nearly 18% compared to previous imports
• Feed waste in ponds: reduced by up to 12% thanks to better floatation and durability
• Customer confidence: neighboring farms now queue up to purchase excess feed — a small but growing sideline business

With local production, the farm no longer worries about feed shortages during shipping delays, something that hurt them badly during the pandemic years.

Looking Ahead: Scaling With Confidence

The farm already plans to add a small pelleting line for prawn feed by next year. They may also expand to produce pet fish feed — a market that has seen steady growth in Australia as backyard aquariums and ornamental ponds gain popularity.

The current twin screw fish feed extruder will handle these new products easily with minimal adjustments.

Why Other Farmers Should Take Notice

This case shows why the large fish feed extruder, twin screw fish feed pelletizer, or floating fish feed extruder makes sense for Australian conditions.

With reliable local raw materials, strict biosecurity, and high domestic demand for premium fish, in-house feed production is a smart step for farms that want to control costs and maintain product quality.

RICHI’s robust equipment, straightforward installation, and practical after-sales support mean farmers don’t have to figure it all out alone. Instead, they gain a long-term partner who understands how to turn a single piece of core machinery into a springboard for a modern feed operation.

Final Thoughts: A Practical Way Forward

This 6T/H large fish feed extruder in Australia is not just a piece of metal — it’s a sign of how local aquaculture can become more resilient and profitable.

The farm’s management sums it up best: “We wanted to stop worrying about late containers and start feeding our fish exactly what they need, when they need it. This extruder does that — and more.”

For other Australian fish farms ready to make the same leap, RICHI stands ready to deliver durable, efficient, and easy-to-maintain extrusion solutions — from small standalone units to future full lines.
