Introduction of Fish Feed Pellet Making Machine
One of the biggest challenges in fish farming is preventing fish feed from polluting the aquatic environment. This is easily solved by fish feed Pellet Making Machines. Like Molino peletizador para piensos animaless, they are equipped with a conditioning system. Therefore, the raw materials easily gelatinize under steam, and during extrusion, they easily bind together, resulting in pellets that don’t break down for a long time. For example, one of our Russian customers purchased a 5-6 ton SZLH350 feed pellet mill to produce sinking fish feed, and reported that the fish feed pellets remained intact in water for over 3 hours.
This customer’s fish pellet making machin is equipped with a 3-layer conditioner. This configuration can also be used to produce shrimp feed pellets. It’s an excellent choice for aquaculture feed mills that want to produce multiple species. At the same time, we also have fish feed extruders specifically designed for producing floater feed. You can choose the appropriate equipment according to your needs.

Application of Fish Feed Pellet Making Machine
Every customer has diverse needs for fish feed. RICHI Machinery primarily manufactures two types of fish feed machines for sale: sinking fish feed pellets and floating fish feed pellets. Both types of equipment can produce feed for surface, mid-water, and deep-sea fish. Sinking fish feed Pellet Making Machines are inexpensive and ideal for feed processing plants seeking low-investment options. For superior floating fish feed, you can try a dedicated floating fish feed pellet machine.
sinking fish pellet machine
- Application: Carp, crucian carp, catfish, and other bottom-dwelling fish
- Pelletizing Technology: Conditioning and Extrusion Process
- Features: The fishing pellet making machine has fewer processing steps, is compact and convenient, has low power consumption per ton, and is inexpensive.
- Application Scope: This type of pellet mill produces pellets quickly, resulting in higher output. It is ideal for traditional fish feed processing and sales, offering excellent value for money.
- Particle characteristics: The pellets are dense and compact. When feeding fish, the feed will sink directly into the water and remain there for 2-4 hours.
If you want to produce high-quality fish feed, you can choose the appropriate equipment based on the characteristics of your raw material formulation. For example, a Vietnamese customer wants to produce floating fish feed, adding a high proportion of fishmeal and soybean meal to the feed formulation. Therefore, to process this high-protein, high-oil raw material, he chose a twin-screw floating feed pellet mill, whose interlocking twin screw design provides better anti-slip properties. However, if your floating fish feed formulation only contains common ingredients such as corn and wheat, choosing a single-screw fish food pellet making machine would be more cost-effective.
floating fish pellet making machine
- Classification: Twin-screw Fish Feed Pellet Extruder and Single-screw Fish Feed Pellet Extruder
- Application: Fish food for silver carp, tilapia, grass carp, and other floating or slow-sinking fish. It can also be used as a food for submerged fish.
- Pelletizing Technology: High-temperature extrusion and shearing
- Features: It can adapt to the production of high-energy formulations. The equipment has a self-cleaning function, making maintenance simpler.
- Particle characteristics: The fish feed is highly mature and has better water resistance, remaining intact even after being submerged in water for dozens of hours.
- Application Scope: Single-screw fish feed pellet mills have a simple structure and are more suitable for small-scale farms or feed processing plants. However, for large aquaculture farms that want to produce high-quality floating feed, twin-screw fish feed Pellet Making Machines are more suitable, as they offer superior extrusion and expansion effects.

Structure of Fish Feed Pellet Making Machine
— Maquinaria Richi —
If you want a high-quality fish feed Pellet Making Machine, you need to disassemble the machine and take a look. Only by understanding the core structure of the equipment and the materials of its key components can you truly judge its performance and lifespan. This article will introduce the core structure of a sinking fish feed pellet mill, which we believe will provide practical assistance in your purchase.
Sistema de alimentación
For different raw materials to enter the fish feed pellet mill smoothly, the feeding mechanism is crucial. RICHI Machinery addresses this by equipping its systems with variable-frequency feed. When the raw material is a coarse fiber, such as wheat bran, the feeding speed can be appropriately slowed, allowing the material ample time to enter the pellet mill, thus reducing material waste at the source.
Conditioner
The fish feed conditioner is made entirely of 306 stainless steel, effectively preventing corrosion from raw materials. In high-moisture conditioning environments, protein- and oil-rich ingredients such as fishmeal and shrimp meal can rapidly degrade conventional carbon steel. By contrast, the use of stainless steel significantly enhances corrosion resistance and ensures stable long-term operation.
Sistema de peletización
Similar to the conditioner, the ring die, pressure roller, and cutter are all made of alloy steel. More importantly, the pelleting section is highly adaptable. RICHI Machinery offers ring die orifices ranging from 2-12mm, allowing you to produce suitable feed for fish at all stages of growth. It’s not only suitable for aquaculture but also for poultry and livestock feed. Changing the feed length can be achieved by adjusting the distance between the cutter and the ring die.
sistema de transmisión
The drive system is the lifeblood of the entire fish feed Pellet Making Machine. A Siemens motor provides power, and couplings are needed to bridge this power source throughout the pelleting process. Finally, a reducer ensures the pressure rollers and ring die have sufficient force to guarantee pellet formation. Together, they ensure stable torque output from the pellet mill, resulting in uniformly sized pellets.
Features of floating fish feed extruder technology
— Maquinaria Richi —
- Simple overall structure, stable and efficient production
- Similar to the sinking fish feed Pellet Making Machine, this equipment is also equipped with a frequency converter, which can adapt to various high-protein and oily raw materials.
- The screw is made of wear-resistant and high-resistant alloy materials, which can effectively extend the service life of the equipment.
- The raw materials expand as they pass through the die. We offer die sizes to suit the nutritional needs of mid-to-upper-level fish throughout their growth stages.
- The screw conveys and extrudes the raw material, forming shaped granules.
- The blades of fish feed extruders are thinner than those used for poultry feed, such as chicken and duck. This is specifically designed to accommodate the finer particles in fish feed.

Fish feed production line process
Fish feed Pellet Making Machines are the core equipment in pelleting. However, each customer has different raw material formulations or applications. Sometimes, a single machine cannot meet diverse needs. Therefore, multiple auxiliary machines are often needed to form a complete production line to efficiently produce the high-quality fish feed pellets you require. Below is a typical fish feed production line to help you understand the main processing flow.
1
Limpieza y procesamiento de materias primas
Depending on production volume, you will need to prepare sufficient raw materials. Newly transported raw materials need to undergo cleaning in the equipment to remove impurities. To ensure the safety of the entire process, the raw materials require cleaning at multiple stages.
2
Crushing stage
If your raw materials are already in powder form, you can mix them directly. If the raw materials are coarse, they will need to be ground. Unlike regular animal feed, the material will be ground twice to achieve a finer consistency. The finer the consistency, the easier it is for fish to digest.
3
Mixed Section
After being pulverized, the material enters a mixer for batch processing. Generally, it undergoes three mixing stages. First, the coarsely pulverized materials are mixed. Then, after a second pulverization, the fine powders are mixed again to ensure a balanced particle size distribution in each batch.
4
Sección de granulado
After mixing, pelleting can begin. The type of equipment can be selected based on the type of feed. The raw materials enter the pellet mill through the feed inlet. If it’s a fish pellet mill or a wet extruder, the raw materials need to undergo high-temperature steam conditioning. Then, the ring die rollers or screw, will extrude and shear the raw materials to form pellets.
5
Sección de secado
Freshly produced pellets are at high temperature and humidity. If transported or stored directly, they are prone to breakage or mold. Therefore, a dryer reduces the moisture content of the feed pellets to below 13%.
6
Spraying and Packaging System
For better palatability, you can add oils or vitamins after drying using a spray system. Then, it enters a cooling system to cool and set. After sieving, qualified feed pellets are packaged for transportation or storage.

Preguntas frecuentes
I want to produce fish feed. With so many types of equipment, which one should I choose?
+
Don’t worry, I will now explain the differences between the various floating fish feed Pellet Making Machines:
Single-screw floating fish feed machine for sale
- Structure: As the name suggests, a single-screw pellet mill consists of a single screw and a barrel, making it relatively simple in structure and cheaper. It primarily relies on friction between the screw and the material to transport it. It can only operate when the barrel is completely filled with raw material.
- Application: Suitable for formulations with high starch content. With a production capacity between 0.8 and 3 tons per hour, it’s a good choice for small to medium-sized aquaculture farms or feed processing plants with lower production requirements.
Twin-Screw floating fish pellet machine for sale
- Basic structure: This type of pellet mill has two screws. When pushing and extruding material, it relies on the extrusion friction of the twin screws, making it less dependent on the raw material. Therefore, it excels at processing high-fat, high-protein formulations. Furthermore, the screws and sleeves are replaceable, broadening its applicability.
- Scope of use: If you want to process complex raw materials and seek fish feed with better water resistance, then the twin-helix feed pellet mill is your best choice.
Single-screw Máquina extrusora flotante para pienso de pecess also come in dry and wet types:
Dry extruders primarily rely on mechanical friction to increase temperature and pressure, promoting pellet expansion. They have a simple structure and low investment costs.
Wet extruders require an additional boiler to add steam. With the help of steam, the final pellet maturity and expansion are better. Furthermore, the high temperature softens the raw material, making it easier to demold and increasing output.
You can select the appropriate equipment based on the above information. Or you can contact us directly.
If I want to produce floating pellet fish feeds, and my raw materials have a high oil content, can your fish feed Pellet Making Machine pelletize them?
+
It also depends on the specific oil content. If the oil content of the raw material formula is greater than 8%, the pellet mill will easily slip during processing, affecting normal production. In this case, you need to reduce the oil ratio. If you want to increase the oil content, you can configure a sprayer to directly spray oil onto the porous granules, which will yield better results.
Speaking of which, the moisture content of the raw materials is also a relatively strict requirement for granulators. We recommend controlling the moisture content at around 24%-25%. If this is insufficient, water can be added during the mixing stage. This further promotes starch gelatinization during the high-temperature, high-pressure granulation process, allowing the granules to expand rapidly.
