2T/H Twin Screw Fish Feed Extruder in Vietnam

Why the SPHS120*2 Twin Screw Fish Feed Extruder Was the Perfect Match

The hatchery chose the SPHS120*2 twin screw fish feed extruder machine from RICHI MACHINERY. Its specifications are ideal for a hatchery of this scale:

Choosing a twin screw fish feed pelletizer instead of a single screw design was crucial. Young catfish and tilapia fry need very uniform, small-diameter pellets that float well but don’t break apart easily. Single screw extruders often struggle with such small sizes and oil-rich recipes. The twin screw system guarantees better cooking and shearing for consistently high-quality micro pellets.

Raw Materials: What Goes Into the Feed

• Rice bran: 30% — cheap and plentiful in the Delta
• Broken rice: 20% — high energy, readily available
• Fish meal: 25% — mostly from local fish processing plants
• Soybean meal: 15% — part local, part imported
• Squid liver oil and fish oil: 5% — for added digestible energy and growth
• Vitamin and mineral premixes: 5% — to round out essential micronutrients

This balanced blend enters the floating fish feed extruder machine after being ground and mixed in a small refurbished hammer mill and mixer. The extruder’s steam and differential conditioners pre-cook the raw mix to the perfect moisture and temperature, allowing the twin screws to expand the material into uniform, floating pellets that hatchery staff can easily adjust in size.

Feeding the Future: How the Extruder Changed Hatchery Operations

Before the owner bought the twin screw fish feed pellet machine, he was limited to buying bagged commercial starter feed. Often, the pellet size was not consistent, leading to excess waste — the fry would nibble but not finish, and leftover feed polluted the nursery tanks.

With the new extruder, he customizes pellet diameter down to 0.8–1.2 mm, matching the exact size for different fish stages. He can also adjust oil content seasonally for better energy density when fry need a boost.

Besides catfish and tilapia, the hatchery is experimenting with producing starter feed for snakehead fry — a species growing in popularity among Vietnamese farmers. The floating fish feed extruder can handle the higher protein content and unique oil balance snakehead fry require.

Replacing Outsourced Feed — Not Overnight, But One Machine at a Time

This was not a sudden leap into full-scale feed manufacturing. The hatchery owner knew his limits: he didn’t have space or funds for a complete line, nor did he want to compete with commercial mills directly. Instead, the goal was to cover 60% of his starter feed demand with fresh, self-made pellets, ensuring fry get exactly what they need at critical growth stages.

So far, the strategy works. He still buys some specialized feeds in bulk when needed but produces the daily nursery ration fresh. By starting with the core — the extrusion step — he could instantly control the most critical quality factor without overhauling the whole system.

Payback in Real Numbers: Savings and Survival

• Lower Feed Costs: By blending local rice bran and broken rice, the owner cuts his per-kilo feed cost by 12–15% compared to branded starter feed
• Higher Fry Survival Rates: More uniform pellets mean better feed intake, less stress, and stronger fry. Early tests show survival up 5–7%
• Better Water Quality: Less leftover feed means less waste in tanks, saving time and money on water exchanges

Why the Twin Screw Fish Feed Extruder is a Smart First Step

Many small hatcheries in Vietnam still think they need a whole fish feed production line to break free from expensive branded feed. This hatchery proves otherwise. The twin screw design does the heavy lifting: uniform expansion, stable floatability, and recipe flexibility.

Because the owner already had an old grinder and mixer, his only real investment was the floating fish feed extruder. And because RICHI MACHINERY provides installation and local after-sales support, he didn’t need to hire a whole new team to run the machine.

Highlights of the SPHS120*2 Twin Screw Fish Feed Extruder

• Flexible Pellet Sizes: From micro starter feed to grow-out sizes
• Efficient Cooking: The DC500-244 steam conditioner and DC500*400-300 differential conditioner ensure full starch gelatinization for high digestibility
• Stable Floating Rate: Critical for fry feeding efficiency
• Reliable Capacity: 1.5–2.0 tons per hour is perfect for hatcheries or small grow-out farms
• Durable Parts: Designed to run daily with local raw materials

Vietnam’s Aquafeed Future: Small Steps, Big Results

Vietnam’s aquaculture exports depend on strong hatcheries — but feed remains the single biggest cost and risk factor. By starting with the right twin screw fish feed pelletizer, farms and hatcheries can secure their own supply chain, stabilize costs, and boost product quality without huge capital outlays.

More hatcheries are realizing they don’t need to compete with giant feed mills. They just need the right gear — like a flexible, reliable fish feed extruder machine — to produce exactly what their fish need, when they need it.

Why This Hatchery Chose RICHI MACHINERY

• Proven performance of the floating fish feed extruder machine with local ingredients
• Fast delivery and on-site commissioning support
• Practical advice on integrating the extruder with older mixing and grinding machines

He knew he wasn’t buying a toy — he was investing in a workhorse that would run every day with minimum downtime.
