This is a project about double screw extruder machine in Argentina. The client needed an extruder that could handle floating fish feed pellets with high starch content while maintaining durability and water stability.
This is a project about double screw extruder machine in Argentina. Argentina's aquaculture industry has been expanding rapidly, driven by increasing demand for fish products such as tilapia, trout, and pacú. A mid-sized aquafeed manufacturer in Argentina was facing challenges in meeting production demands due to outdated machinery. Their existing extruder struggled with inconsistent pellet quality, high energy consumption, and frequent breakdowns, leading to production delays.
To stay competitive, the client decided to invest in a high-capacity double screw extruder machine from RICHI Machinery. Unlike a full production line, they only needed a single extruder to replace their old, inefficient unit while integrating it with their existing mixer, dryer, and packaging system.

The client needed an extruder that could handle floating fish feed pellets with high starch content while maintaining durability and water stability. Their primary feed formulations included:
After evaluating different models, they selected the SPHS150×2 double screw floating fish feed machine due to its high output (5-6T/H) and ability to process both floating and slow-sinking pellets. The larger screw diameter (150mm) ensured better shearing and gelatinization of starch, crucial for floating feed.
| Parameter | Value |
|---|---|
| Main Motor Power | 200 kW |
| Screw Diameter | 150 mm |
| Feeder Power | 1.5 kW |
| Conditioner Power | 11 kW |
| Differential Conditioner Power | 15 kW |
| Production Capacity | 5–6 T/H (Tons per Hour) |
The twin-screw extrusion technology allowed precise control over pellet density, ensuring optimal floating properties. Unlike traditional pellet mills, this fish feed extruder could adjust expansion ratios, making the feed more digestible for fish. The pellets had:
The SPHS150×2 double screw extruder machine in Argentina consumed 30% less energy compared to their old machine, thanks to its high-torque motor and optimized screw design. The differential conditioner also improved steam absorption, reducing raw material waste.
Beyond standard fish feed, the twin screw wet type fish feed extruder machine could also produce:
This versatility allowed the client to diversify their product range without additional equipment.
Argentina's aquaculture sector relies on locally available raw materials, and RICHI's double screw extruder machines in Argentina are designed to handle high-fiber and high-starch ingredients efficiently. Unlike pellet mills (which cannot produce floating feed), double screw extruders are ideal for:
The client appreciated:
By choosing the RICHI SPHS150×2 double screw extruder, this Argentinian feed manufacturer significantly boosted production efficiency, improved pellet quality, and reduced operational costs. The machine’s ability to process multiple feed types made it a future-proof investment.
