Core Advantages of Our Equipment
A high-quality floating fish feed extruder machine is essential for producing nutritious and water-resistant aquatic feed pellets. With advanced extrusion technology and a robust mechanical design, our extrusion equipment helps customers achieve consistent product quality, efficient production, and long-term operational reliability.
Excellent Floating & Water Stability
RICHI floating fish feed extruder utilizes advanced extrusion technology; through high-temperature, short-duration conditioning and powerful extrusion, it enhances starch gelatinization and nutrient digestibility, producing buoyant, water-stable pelleted feed. The finished pellets maintain their structural integrity in water, significantly reducing nutrient leaching and improving feed utilization efficiency.
Durable Structure for Long Operation
Our machine utilizes high-quality components and a robust mechanical structure to ensure long-term, stable operation. It features wear-resistant extrusion components that extend service life and a heavy-duty drive system that supports continuous, uninterrupted production, while allowing for precise control of temperature and pressure.
Smart and stable production
Our floating fish feed extrusion machine offer an optional modular intelligent control system. Operators can monitor and adjust key process parameters—such as temperature, humidity, and screw speed—in real time, ensuring highly consistent product quality during mass production while minimizing the need for manual intervention.
Flexible Pellet Adjustment
Different aquatic animals require different feed characteristics. RICHI floating feed extruder machine allows precise control of pellet diameter, length, density, and floating time through adjustable extrusion conditions and cutting systems. This flexibility helps feed manufacturers serve multiple markets with one production system.
Technical Parameters
Based on screw structure and processing technology, floating fish feed extruders can be classified into twin-screw extruders, single-screw extruders, dry-type extruders, and wet-type extruders. Single-screw extruders are suitable for small-scale production and are cost-effective, whereas wet-type twin-screw extruders are suitable for large-scale, continuous production.

Looking for a customized floating fish feed production solution? Contact RICHI to discuss your project requirements.
Russia 1.5-2 т/H Wet Type Floating Fish Feed Extrusion Machine
The customer is an aquatic feed manufacturer specializing in the production and supply of feed products for local fish farming businesses. With the increasing demand for high-quality aquaculture feed, the customer planned to upgrade its production capability and expand its product range from traditional sinking feed to floating fish feed.
Based on the customer’s production requirements, target feed products, and investment plan, RICHI designed a customized floating fish feed production solution. By adjusting key parameters, the equipment is capable of producing both floating and sinking fish feed.
Indonesia 0.8-1 т/H Dry Type Floating Fish Feed Extrusion Machine
The client is a small startup aquatic feed manufacturer with limited factory space and a low investment budget, and they did not require exceptionally high standards for feed digestibility or water stability.
Based on these specific circumstances, we designed a dry-process extrusion solution for them. Compared to the wet extruder, dry fish feed extruder eliminates the need for external steam boilers, simplify installation, consume less energy, and is more economical in daily operation.
Qatar 1-1.5 T/H dry floating Fish feed extrusion machine
This client, targeting the booming sea bass farming industry in Qatar, planned to invest in building a sea bass feed production line. The client wanted to control initial investment costs, achieve rapid production, and avoid complex supporting infrastructure. Therefore, we provided the client with a dry type fish feed production solution that is fully capable of processing conventional grains and protein powders.
Saudi Arabia 3-4 T/H Wet Type Fish & Shrimp Feed Pellet Extruder
The client requires large-scale production of floating fish feed (for mainstream farmed species such as sea bream and bass) and sinking shrimp feed. The client has high requirements for feed quality; the pelleted feed needs to have high water stability, high starch gelatinization, and precise density control. Therefore, we recommend that the client use a wet twin-screw extruder equipped with a double-layer conditioner as the core pelleting equipment.
Bangladesh 0.3-0.5 T/H Single Screw Floating Fish Feed Pellet Extruder
The client plans to produce both floating fish feed and chicken feed on a single production line. They want to control equipment investment and reduce redundant purchases. Therefore, we provided a configuration where two independent pelleting cores (dry fish feed extruder + single-layer conditioner ring die pellet mill) share a common front-end crushing and mixing system and a rear-end cooling, screening, and packaging system.
Floating fish feed extrusion process
Producing high-quality floating fish feed involves much more than selecting the right extruder. Every stage of the production process—from grinding to mixing, extrusion, drying, coating, cooling, and packaging—plays an important role in determining pellet quality, nutritional value, production efficiency, and operating costs.
As a professional aquatic feed equipment manufacturer, We provide complete floating fish feed production solutions tailored to each customer’s raw materials, production capacity, feed formulations, and automation requirements. Our engineering team designs every processing stage to ensure stable operation, efficient material flow, and consistent pellet quality, helping customers build reliable and profitable aquafeed manufacturing facilities.

Frequently Asked Questions
How do I choose the right floating fish feed extruder machine?
→
Choosing the right extruder depends on a variety of factors, including your required capacity, target fish species, pellet size, feed formulation, plant size, and investment budget. RICHI engineers will recommend the most suitable extruder and production line configuration based on your specific circumstances.
What types of feed can a floating fish pellet feed extruder produce?
→
Our equipment can manufacture much more than floating fish feed. By adjusting the extrusion process and feed formulation, it can also produce sinking fish feed, slow-sinking fish feed, shrimp feed, crab feed, ornamental fish feed, and feed for other aquatic species.
What raw materials can be processed?
→
Commonly used ingredients include fishmeal, cornmeal, wheat flour, rice bran, soybean meal, rapeseed meal, vitamins, minerals, vegetable oils, and other nutritional additives. RICHI can optimize extrusion equipment configuration based on your specific feed formulation.
What is the difference between a wet type and a dry type fish feed extruder?
→
A wet fish feed extruder utilizes steam conditioning, achieving higher yields, better starch gelatinization, and superior pellet quality, making it suitable for large-scale commercial aquatic feed production. A dry extruder generates heat through mechanical friction, eliminating the need for external steam boilers, making it an ideal choice for small and medium-sized feed producers or fish farmers.
Can one extruder produce both floating and sinking fish feed?
→
Yes. Depending on the feed formulation and extrusion parameters, the same machine can produce floating, slow-sinking, or settling pellets. Our engineers can recommend the appropriate configuration based on your target product.
What pellet sizes are available?
→
Depending on the extruder model and die configuration, the pellet diameter can usually be customized, ranging from approximately 0.5 mm to 12 mm, allowing for the production of pelleted fish feed for various growth stages.
Can the floating fish feed pellet extruder be customized?
→
Yes. We customize equipment according to production capacity, feed formulation, pellet specifications, automation level, factory layout, and local power supply to ensure the production line matches your operating requirements.
How much does a floating fish feed extruder machine cost?
→
Pricing depends on a variety of factors, such as production capacity, machine configuration, level of automation, material requirements, and whether a complete production line is needed. Please contact RICHI and provide your project details for a customized quote and technical solution.
What is the equipment warranty period? What kind of technical support do you provide?
