Twin Screw Fish Feed Extruder
This twin screw fish feed extruder is suitable for large-scale processing of aquaculture feed and pet food. Its twin-screw design accommodates various feed formulations, producing clean, easily digestible feed. A single unit can achieve an output of 0.5–12 T/H. For broader customer needs, we also offer customized extruders and comprehensive production solutions.
What is twin screw fish feed extruder?
Different from single-screw extruder, this equipment offers more stable output and can process a wider variety of feed types. As a high-quality feed processing machine, it is particularly well-suited for producing premium aquaculture feed.
Efficient Pelletizing Capability
With dual-screw technology, it offers superior mixing capabilities, making it capable of handling a wide range of complex feed formulations. The screws feature variable-frequency speed control, allowing for adjustment of pellet density and expansion levels. Whether producing floating, semi-floating, or sinking feed, the process is effortless.
The two screws are designed with a fully meshed, zero-gap structure, enabling more effective control over raw material feeding, compaction, and extrusion. The curing time of the material within the barrel determines the final expansion of the pellets. This process is fully adjustable.
Besides a robust structure, the machine is also easy to operate. Each twin-screw fish feed mill is equipped with a PLC and touchscreen control system, making it convenient to adjust production requirements. Its excellent production capacity meets the demand for high-quality aquatic feed as well as pet food for cats and dogs.

They deliver not only high-efficiency, energy-saving performance but also feature structural stability and a long service life. These advantages can help boost your feed production projects and provide a higher return on investment.
High Raw Material Adaptability
This equipment is equipped with a variable-frequency drive motor, allowing for precise control of the twin-screw operating speed. As a result, it can accommodate various raw material formulations, including corn, soybean meal, wheat, fish meal, rice bran, and aquatic feed additives. By producing fish feed with different buoyancy levels, it meets the feeding habits of various fish species.
High Output Per Unit
Our twin-screw fish feed extruder machine increases capacity per unit by 20%. The tight fit of the twin-screw structure ensures thorough extrusion of the material, effectively preventing residue. While ensuring high quality, shear force is distributed evenly within the extrusion chamber, thereby increasing capacity per unit.
Long Service Life
Each twin-screw extruder is equipped with a Siemens industrial-grade motor, ensuring stable power output. The drive housing is fitted with FAG or SKF bearings, making the overall structure more robust. This ensures long-term, stable operation of the equipment and reduces operating costs.
Excellent Wear Resistance
Each screw set is made of the new wear-resistant alloy 38CrMoAi and features a double-layer metal expansion chamber liner. These features ensure reduced wear during long-term operation, while improving feed quality and unit output. The equipment maintains high-efficiency performance even during continuous, extended production runs.
Higher-Quality Pellets
With die diameters ranging from 0.6 mm to 20 mm, this machine can produce feed pellets in a wider variety of sizes. The resulting pellets feature a uniform appearance and excellent water resistance. The cutting mechanism is controlled by a variable-frequency motor, allowing for precise adjustment of pellet length. A turbulent discharge system further enhances the aesthetic quality of the pellets.

Auxiliary Equipment for fish feed Production
In addition to advanced twin screw fish feed extruder, we have designed efficient auxiliary equipment for each process stage. The following are processing systems commonly used in fish feed production, including raw material handling, pellet cooling, and packaging. Together with the extruders, this equipment supports highly efficient and profitable fish feed processing projects.
Raw Material Crusher
The hammer mill can crush small-sized grains, such as corn, wheat, oilseed meal, and legumes used in fish feed. The crushed material is reduced to a size of 3–5 mm, making it easier to pelletize.
Feed Mixer
It can blend various feed production materials. The mixed ingredients can be extruded into feed pellets with a more uniform texture, thereby ensuring consistent nutritional content in every pellet.
Mesh Belt Dryer
Freshly extruded fish feed pellets can have a moisture content of over 22%. This gentle mesh belt dryer can reduce the moisture content of feed pellets by more than 10%, extending the feed’s shelf life.
Spraying Machine
It sprays edible oil or attractants onto feed pellets to enhance the palatability. Feed pellets treated with oil spraying have a smoother and more even surface, thereby meeting the high-quality feed needs.
cooling machine
This unit cools and sets the dried feed, lowering its temperature from 80°C to just above room temperatures by 3–5°C.This helps solidify the fats in the feed, facilitating packaging and transportation.
Packaging System
It enables automatic weighing and packaging, facilitating product sales. The packaging size is typically 10 to 50 kg per bag. You can use heat sealing, string sealing, or a combination of both.
Frequently Asked Questions
We offer free equipment consultations and solution introductions for twin-screw fish feed extruder. If you have any questions about this equipment, you can find the answers below. Alternatively, feel free to contact us anytime to provide your specific production requirements.
Can this twin screw fish feed extruder produce sinking aquatic feed?
+
Our twin-screw extruder can produce floating, semi-floating, and sinking feed types. It can accommodate various feed formulations. This is achieved by adjusting water temperature and screw speed.
Therefore, this equipment is particularly suitable for production tasks with diverse feed requirements, offering a high return on investment. Examples include tilapia feed, carp feed, catfish feed, and shrimp feed.
What is the difference between this twin-screw extruder and a single-screw extruder?
+
The most obvious difference lies in their structural variations, which result in different applications. Single-screw extruders have a simpler design and are suitable for basic aquafeed and animal feed production. With lower investment costs, they are ideal for small-scale production capacities of less than 1T/H. They can also produce both floating and sinking feed.
Twin-screw extruders are suitable for high-capacity production ranging from 1 to 12 T/H and above. They have a broader range of applications and can accommodate a wider variety of feed formulations. Due to the close alignment of the twin screws, they provide superior material extrusion and more stable formation rates. You can use them to produce high-end aquaculture feed and pet food. In the long term, they offer a higher return on investment.
What sizes of feed pellets can this twin screw fish feed extruder produce?
+
Common fish feed pellet diameters range from 1 to 6 mm. This equipment can accommodate a diameter range of 0.8 mm to 12 mm, making it suitable for various fish species. Smaller-diameter pellets are ideal for fry rearing, while larger-diameter pellets are required for market-sized fish.
The equipment allows for quick switching between different specifications by replacing dies with varying pore sizes. Investing in a single unit enables the production of feed pellets in different types and sizes, leading to higher returns on investment.
How to choose the right twin-screw fish meal extruder?
+
First, you need to consider your desired hourly production capacity. If your capacity exceeds 1 ton per hour, you can directly opt for a twin-screw extruder. This is because it offers more stable output and can accommodate a wider variety of feed types and higher production volumes.
For operations requiring multiple feed formulations and production specifications, an integrated production system is recommended. With the support of various auxiliary equipment, feed production becomes more efficient. A complete production line solution offers better value for money and reduces future production investment. We can provide customized design solutions to meet all your production needs.
