Multi-functional FISH Feed PRODUCTION LINE
The multifunctional fish feed production line breaks the limits of traditional aquafeed systems.
With just one line, you can easily produce floating and sinking fish feed, shrimp and crab feed—and even expand into livestock (pig, poultry, cattle, sheep) and pet food production.
A single investment, endless possibilities for your feed business!
Multifunctional FISH Feed Production Line Overview
A multi-functional feed production line is an integrated equipment system designed to flexibly produce various types and specifications of animal feed.
Through modular design and process adjustments, it can be used for producing aquatic feed (like floating/sinking fish and shrimp feed), livestock and poultry feed (such as pellets for pigs, cattle, and chickens), pet food (like cat and dog food), and even feed for special economic animals.
Applicable Raw Materials
Cereals (corn, wheat, rice bran, vegetable oil, fish oil), proteins (soybean meal, fish meal, meat and bone meal), fiber (wheat bran, alfalfa meal), functional additives (vitamins, minerals, probiotics), and special-purpose ingredients (colorants, binders)…

Feeds Covered by Multi-functional FISH Feed Production Line
The feed market is becoming increasingly segmented, and customers are raising a wider variety of animals. Therefore, many feed mills are no longer choosing production lines capable of producing only one type of feed. Instead, they switch to “multi-functional feed production line”. This offers greater flexibility and helps make better returns on initial investments.
It can be used to produce the following four types of feed:

Aquatic Feed
- Fish Feed
- Shrimp Feed
- Crab Feed
This line can flexibly meet various aquatic feed demands. Whether for floating or sinking fish feed, it allows for precise control over expansion and density. Shrimp and crab feed pellets are finely made and highly water-resistant, meeting feeding requirements in different farming environments.

Pet Food
- Cat Food
- Dog Food
- Ornamental Fish Food
By adjusting molds and formulas on the pet food extruder, it can produce high-expansion pellets in multiple sizes. The resulting products have a full appearance, good palatability, and more easily absorbable nutrients, helping manufacturers easily enter the growing pet food market.

Poultry Feed
- Chicken Feed
- Duck Feed
- Goose Feed
For poultry feed production, an animal feed pelletizer is mainly used to form the pellets. Formulas and pellet size can be flexibly adjusted according to the different growth stages of poultry, meeting the practical needs of large-scale farming.

Livestock Feed
- Pig feed
- Cattle feed
- Sheep feed
An animal feed pelletizer is also used for processing livestock feed. For pig, cattle, or sheep feed, the line balances energy supply with protein absorption, helping farmers improve feeding efficiency.
MULTI-FUNCTIONAL FISH FEED PRODUCTION LINE SOLUTION SECTION
Each stage of the multi-functional feed production line features a modular design. Based on a customer’s specific production needs, each process section can be flexibly added or removed.
Furthermore, even within the same section, equipment configurations can be adjusted according to the type of raw material and desired production capacity.
This design ensures the production line has high flexibility and scalability, allowing different customers to get a solution that is best suited for them.
01 Pre-processing
This stage involves cleaning and removing impurities from raw materials.
Some high-moisture or large-particle raw materials (like whole corn or cassava) may also require coarse crushing or conditioning.
01 Pre-processing
This stage involves cleaning and removing impurities from raw materials.
Some high-moisture or large-particle raw materials (like whole corn or cassava) may also require coarse crushing or conditioning.
02 Crushing
Large or hard raw materials are crushed into uniform particles or powder. Particle size directly affects mixing uniformity, pelleting strength, and animal digestibility. Aquatic and pet feed often require a finer grind to facilitate extrusion and stability in water.
03 Batching and Mixing
Various powdered or granular raw materials are thoroughly mixed according to the formula ratio. Mixing time and uniformity are key control points for ensuring feed quality.
04 Pelletizing/Extrusion
- Aquatic Feed: Floating or sinking fish/shrimp feed can be produced using an aquatic feed pellet mill or aquatic feed extruder.
- Pet Food: Twin screw extruders are typically used for making cat and dog food.
- Poultry/Livestock Feed: Chicken, duck, pig, cattle, and sheep feed can be produced using an animal feed pelletizer.
Different equipment is selected based on the type of feed produced:
This step determines the physical form, water resistance, and digestibility of the feed.
05 Drying Section
Removes excess moisture from the feed after pelleting or extrusion. Drying temperature and time must be precisely controlled to avoid surface hardening or nutrient loss.
06 Spraying Section
Oils, additives, or palatants are sprayed onto the feed pellets. This step is especially crucial for high-end aquatic and pet foods..
07 Cooling Section
The high-temperature feed from drying or spraying is cooled to a suitable temperature for packaging and storage. This prevents the pellets from becoming damp or deformed, ensuring stable quality.
08 Screening Section
Finished feed is sieved to remove powder, oversized, or undersized particles generated during production.
Unqualified pellets can be sent back to the mixing or pelletizing stage for reuse, reducing waste.
09 Packaging Section
Through automated weighing, bagging, sealing, and palletizing, the finished products are prepared for warehousing or shipment.
Packaging can be customized based on needs, such as valve bags, standard woven sacks, or small vacuum-sealed packages. Some premium products are also equipped with moisture-proof inner liners..

FAQ ABOUT MULTI-FUNCTIONAL FISH FEED PRODUCTION LINE
If you have any questions about this line, you can first take a look at these answers.
1. What is a multi-functional feed production line?
+
It’s a “one-line, multiple-use” system for producing animal feed.
Unlike traditional lines that only make one type of feed (like fish or shrimp feed), it can flexibly switch between different products on the same line. It can produce fish feed and pet food, as well as specialized feed for pigs, chickens, cattle, sheep, and other livestock.
For farms or feed mills, this means you no longer need to invest in several separate lines. One line covers all your production needs, saving you equipment costs and simplifying maintenance.
2. What is the difference between a multi-functional feed production line and a regular fish feed production line?
+
Regular fish feed production lines specialize in aquatic feeds, such as floating or sinking fish feeds.
Multi-functional feed production lines are more flexible; they can produce feeds for fish, shrimp, and crabs, and can also extend to pet and livestock feeds.
For clients, this not only improves equipment utilization but also allows for rapid adjustments to the product structure based on market demand, maximizing investment returns.
3. What raw materials can a multi-functional feed production line process?
+
No need to worry about raw material selection. Common raw materials like fishmeal, soybean meal, cornmeal, wheat bran, rice bran, bone meal, and vitamin additives are all handled without issue.
Even for more specialized raw materials, such as high-protein silkworm pupa powder (commonly used in aquatic feed and pet food) or high-fiber alfalfa powder (common in poultry and livestock feed), our multi-functional feed production system can handle them well, without issues like feed jams or poor pellet formation.
4. Will switching products on a production line be troublesome?
+
Not at all. The multi-functional line was designed with easy switching in mind. You don’t need to dismantle equipment or make major process changes; everything is managed through an automated control system.
For example, if you want to switch from fish feed to poultry feed, you just adjust the parameters in the system and turn certain sections on or off as needed (e.g., if some ingredients don’t require grinding, you simply shut down the grinder).
The entire process is fast and requires minimal manual labor. Crucially, the quality of the feed produced after switching is just as good as when dedicated to a single product.
5. What is the capacity range of the multi-product feed production line?
+
There is no fixed limit on capacity; we fully customize it to meet your actual needs.
We have completed many projects, from small-scale clients just starting out who need a 0.5-ton/hour pilot line to test formulas and build a customer base, to large manufacturers aiming for national or export markets requiring massive lines of over 20 tons/hour with complete systems from storage to packaging. We can handle it all.
6. Can the size of the feed pellets produced be adjusted?
+
Yes, and the adjustment range is quite wide. Different animals and different growth stages require significantly different pellet sizes.
For example, young fish need small pellets, while adult pigs or beef cattle need larger and harder pellets. Our equipment takes these details into account, allowing the pellet diameter to be freely adjusted between 0.6-12 mm.
7. What kind of customers are best suited for a multi-product production line?
+
The ideal customers are those involved in “multi-species farming” or “multi-product processing.” This includes:
Farms that raise fish, shrimp, and crab, as well as pigs, chickens, and cattle. They might have previously needed two separate lines (one for aquatic feed, one for livestock), but now a single multi-functional line is enough.
Feed mills looking to expand their product line to include aquatic feed, pet food, and livestock/poultry feed simultaneously. This lowers investment costs and provides the flexibility to respond to market changes (e.g., producing more of whatever sells best) instead of being tied to a single product.
8. Can the multi-functional feed production line equipment be customized to my specific needs?
+
Absolutely! We provide full-process customization tailored to your needs; we won’t blindly recommend a pre-made solution that doesn’t fit you.
Every client has unique circumstances—some have limited factory space, others use special raw materials, and production needs vary. We first understand your specific situation, then help you plan the most suitable layout, select the right equipment, and arrange installation and commissioning.
Throughout the process, you can communicate directly with our engineers to ensure the equipment runs stably according to your exact requirements.
