What is the fish feed production line
A fish feed production line is a complete set of equipment for fish feed manufacturing.
It processes various raw materials, including:
- Protein sources: fish meal, shrimp meal, meat and bone meal, soybean meal, cottonseed meal, corn gluten meal
- Energy sources: corn flour, wheat flour, rice bran, wheat bran
- Fat sources: fish oil, corn oil, phospholipid oil
- Binders: wheat flour, corn flour
- Additives: minerals, vitamins, amino acids, antioxidants, probiotics
Key processes include crushing, mixing, extrusion/pelletizing, drying, coating, cooling, screening, and packaging. The line produces fish feed of different specifications, covering the needs of almost all freshwater and marine aquaculture species. It enables standardized, large-scale production.

Working Process of Fish Feed Production Line
A fish feed production line is an integrated system engineered to convert raw ingredients—such as fishmeal, soybean meal, grains, vitamins, and other nutritional additives—into uniform, nutrient-dense aquatic feed pellets.
This is achieved through a sequenced process that includes raw material cleaning, crushing, batching and mixing, conditioning, extrusion or pelleting, cooling, and final screening and packaging.
Raw Material Cleaning
01
During precleaning, various impurities mixed in the raw materials such as stones, metal fragments, rope pieces are removed to protect both the production line equipment and ensuring the hygiene and quality of the final feed.
Crushing
02
Cleaned raw materials are crushed to 80-120 meshes by an ultra-fine grinder to improve feed digestibility. Finer crushing makes pellets denser (more water-resistant) and supports uniform mixing later.
Batching and Mixing
03
After the crushed raw materials are weighed according to the formula, they are sent to the mixer. High-speed stirring ensures the materials are evenly mixed, guaranteeing balanced nutrition.
Conditioning
04
Mixed raw materials enter the conditioner, where they are mixed with steam to achieve sterilization, curing, and gelatinization—enhancing the digestibility and safety of the feed. Meanwhile, the conditioned materials become softer and more plastic, facilitating pelletizing.
Extrusion/Pelleting
05
Both extruders and feed pellet mills can be used for pelletizing. Extruders produce feed that is porous and loose, which can be used as floating fish feed. Pellet mills produce fish feed with strong water absorption, which can only be used as sinking fish feed.
Drying
06
The moisture content of extruded pellets is 20%-30%. Hot air generated by a dryer is required to reduce the moisture of the pellets (both on the surface and inside) to approximately 10%, facilitating safe storage.
Coating
07
RICHI fish feed line uses post-spraying technology to protect heat-sensitive nutrients from thermal processing damage. Moreover, the extruded porous pellets have strong adsorption, greatly increasing oil addition.
Cooling
08
The coated pellets are at a relatively high temperature and need to be cooled by a counterflow cooler to near ambient temperature before packaging. This prevents condensation and mold growth, and maintains pellet crispness.
Screening and Packaging
09
The cooled finished pellets are passed through a vibrating screen to separate broken fines and off-spec particles, ensuring uniform size of the final product. The screened-out fines can be returned to the production process for reuse. The qualified finished feed is then weighed by an automatic packaging scale, filled into feed bags, and sealed.
Key Equipment for Fish Feed Production Line-Feed Pellet Machine and Extruder Machine
Both pellet mills and extruders can be used in fish feed production line, but their working principles and finished pellets differ significantly. Each has its pros and cons, and the choice should be based on factors such as the type of feed to be produced, production scale, and investment cost.
Feed Pellet Making Machine
- Core Function:Press the conditioned powder into hard pellet feed (non-expanded state).
- Processing Temperature: Relatively low (60 – 85°C), mainly relying on steam conditioning.
- Pellet Shape: Sinking feed, with a dense structure and density greater than that of water.
- Key Components: Ring die/flat die, roller, transmission system, cutter.
- Main Advantages: Low equipment investment, low production cost, and high output.
- Suitable Fish Species: Demersal fish (such as carp, black carp, crucian carp, etc.), crustaceans (such as turtles, crabs).
Fish Feed Extruder Machine
- Core Function: Process powder into porous expanded feed through high temperature and high pressure extrusion and shearing.
- Processing Temperature: Extremely high (120 – 180°C), mainly relying on mechanical heat generation from friction and steam heating.
- Pellet Shape: Can produce floating, sinking, and slow-sinking feeds, with a loose and porous structure.
- Key Components: Screw (mainly twin-screw), screw sleeve, mold (discharge hole), shearing element, transmission system.
- Main Advantages: Diversified products, good gelatinization degree, high digestion and absorption rate, and thorough sterilization.
- Suitable Fish Species: Upper and middle layer fish (such as perch, silver carp, ornamental fish), fry/fingerlings, special fish.
Auxiliary Equipment for Fish Feed Production Line
A fish feed production line is a complex systematic project. Apart from the core fish feed extruder machine or feed pellet making machine, a series of auxiliary equipment is also required to work together to produce high-quality feed. RICHI Machinery has been deeply engaged in the R&D and production of animal feed pelletizing equipment for 30 years, ensuring pellet quality and processing line efficiency with professional technology.
Storage Silo
Storage Silos are used for storing raw materials or finished pellets. The storage silos/bins used in the pre-pelletizing stage also have a homogenization function, which can adjust the moisture content difference of materials and ensure the stability of the pelletizing process.
Raw Material Precleaner
It is used for the initial cleaning of feed raw materials. It removes impurities such as hemp ropes, stones, and plastics from the raw materials, clearing obstacles for subsequent processing links and preventing impurities from clogging or damaging equipment.
Fish feed Grinder
An ultra-fine grinder is a high-efficiency crushing equipment that can grind materials to an extremely fine particle size. It can crush raw materials to 80-200 meshes—the finer the crushed particle size, the denser the structure of the extruded feed pellets and the better their water resistance.
Fish feed Mixer
It achieves uniform material mixing through the high-speed rotation of two intermeshing screws, ensuring balanced nutrition. Additionally, the forced conveying structure of the twin screws reduces material residue and enables continuous production.
Fish feed Dryer
Freshly pressed feed pellets have high temperature and high moisture content, making them prone to bacterial growth. RICHI horizontal circulation dryer adopts intelligent temperature control technology, achieving efficient dehydration through stable and uniform hot air while preventing nutrient damage caused by overheating.
Vertical Vacuum Coater
The RICHI-XYPLC series vertical vacuum coaters are capable of adding coated oils (fish oil, corn oil) and liquid biological agents (vitamins, amino acids, antioxidants) to feed, enhancing the feed’s palatability and nutritional value-added. The oil coating amount can be precisely controlled (0-6%), and the coating is uniform without caking.
Counterflow pellet Cooler
Utilizing a principle where pellets and cooling air move in opposite directions, this equipment effectively prevents high-temperature pellets from cracking due to sudden cooling. A distributor installed at the top avoids excessive pile-up of pellets, ensuring uniform cooling.
Bucket Elevator
RICHI bucket elevator ensures smooth vertical material transport to the next process with stable performance. It uses edge-meshing technology ,featuring high strength and good tightness, and is fitted with an explosion-proof port for pressure relief.
Automatic Packing Machine
RICHI DCS Series automatic packer is ideal for quantitative weighing and packaging of pellet /powdery materials, with precise weighing, fast packaging, easy operation. Sewing or thermal sealing is available based on customers’ bag choices.
