Flexible Fish Feed Production Lines Covering Fish & Shrimp Feed, and Pet Food Applications
Fish feed production lines were initially designed for processing all kinds of fish and shrimp feed. However, thanks to technological advances, their capabilities now extend far beyond that.
By adjusting formulations, dies, and extrusion processes, a single production line can flexibly switch between producing fish feed, shrimp feed, or even pet food—enabling truly versatile applications.
In RICHI’s system design philosophy, these lines are not just single-purpose machines; they are multifunctional feed production systems.
This highly scalable design allows factories to efficiently use equipment resources, easily adapt to different feed requirements, and unlock new opportunities in the pet food and specialty animal feed markets.
How Are Fish Feed Pellets Produced?
When many farmers start to invest or run fish feed production, they always ask, “How do I do this? What’s the production process? ” In RICHI, we don’t just give you a fixed plan, instead will tailor your fish feed production process according to your raw materials, plant size and budget.
The whole process——from raw material crushing and mixing, to extrusion, drying, spraying, cooling, and then to molding and packaging——every step is carefully controlled. The fish feed made in this way has even in size, balanced in nutrition, and has a texture your fish will love. It makes daily production smoother and easier, and also helps your farming profits keep steady.

01
Raw Material Processing
This is the first step in the production process of fish feed. It is necessary to carefully pick and clean fish meal, soybean meal, corn and other raw materials to remove impurities and ensure that the raw materials are clean and safe. Only when this step is done right, the following production steps can proceed smoothly.



02
Crushing
Large pieces of fish meal, corn and other raw materials are ground into fine and uniform powder, which lays the foundation for mixing and pellet-making later. The crushing degree can be flexibly adjusted according to the feeding habits and growth stages of different fish, so that the particle size is just right for fish to eat.



03
Mixing
All raw materials are fully blended according to the formula, so that protein, fat, vitamins and other nutrients are evenly distributed. In this way, every single fish feed pellet tastes the same, and the fish can eat more happily and can absorb nutrients better too.



04
Pelletizing & Extrusion
This is the most critical steps in fish feed production. The powdery mixture is extruded to become floating, sinking or slow-sinking pellets, and each one is uniform in size and stable in structure. For fish, it is easier to eat; For farmers, it also means higher feed utilization rate and less waste.



05
Drying
According to the type of pellets and how much moisture they have, the drying temperature and time will be flexibly adjusted to ensure that each batch of fish feed is dry and uniform. In this way, it’s not just convenient for later storage and transportation, but farmers also don’t have to stress constantly about the feed going bad or breaking apart.



06
Spraying
Spraying is to coat the surface of fish feed with a layer of nutrition or fat. This step can increase feed’s flavor and makes it more appealing to fish. Not only does it improve the appetite of fish, but it also make each batch of fish feed more valuable and more popular in the market.



07
Cooling & Screening
After drying and spraying, the pellets need to go through cooling and screening. This brings the feed to a nice temperature, makes sure the hardness is even, and gets rid of broken materials and dust. This step ensures that every fish feed is intact, which also makes packaging and storage more convenient.



08
Packing
The last step of fish feed production process. Automatic packing equipment can complete weighing, sealing and warehousing according to specifications, so that each bag of fish feed is clean, tidy and easy to manage. That way, you can easily store and distribute feed, saving time and effort.

HOW DOES FEED PROCESSING MEET THE DIFFERENT HABITS OF FISH?
Through scientific extrusion, drying and molding processes, fish feed can be made into different types: floating feed floats on the water surface, allowing fish to gather and eat; Sinking feed sinks to the bottom, perfect for bottom fish and less wasteful; Slow-sinking feed finds a balance between floating and sinking to meet the feeding habits of various fish.
The key to achieve this is to use fish feed extruder and fish feed pellet machine reasonably, and flexilbly customize the pellet specifications and formulas according to the fish species and farming mode.

FAQ About fish feed production machine & line
1. How do I choose the right fish feed production line for me?
+
Choosing a fish feed production line is really about looking at your own situation. Like, roughly how much output do you need each day? What raw materials do you usually use? Different fish species have different requirements for pellet size and formulas, too.
Besides that, you’ve got to think about your factory space and budget. Just tell us all this info, and we can help match you with a suitable plan, making subsequent production hassle-free and more tailored to your needs..
2. Why buy a fish feed production line? Can’t I just buy or use a single fish feed pellet machine?
+
A single fish feed pelletizer can indeed turn raw materials into pellets, but it only completes one step of the process. Other steps like crushing, mixing, drying, spraying, cooling, screening, and packaging need to be addressed separately.
In contrast, a complete production line connects all these steps, saving time and effort while also producing pellets with more consistent nutritional value and quality. Especially if you’re planning a long-term, large-scale operation, a production line will provide less worry and greater efficiency and effectiveness.
3. What’s the general price range for your fish feed production line?
+
There’s no fixed price for a fish feed production line, as it depends on your specific needs. Factors like output capacity, degree of automation, equipment configuration, and the types of raw materials processed all affect the investment cost.
Generally speaking, smaller-capacity lines have lower investment costs. Medium to large-scale production lines, while more expensive, offer more stable and long-term returns. Just let us know what you need, and we’ll provide a detailed plan and quote based on your situation, so you can have a clear budget in mind.
4. How do I know if I need to set up a fish feed production line?
+
If you regularly need a large amount of feed, or want to produce different types of pellets yourself (such as floating, sinking, and slow-sinking), then a production line would be a better fit.
In another case, if the cost of buying ready-made feed is high, or your aquaculture scale is gradually expanding, having a stable production line will not only make daily management easier, but also ensure more stable and higher profits.
5. What kind of services do you offer when I buy your products?
+
No need to worry about subsequent use. We’ll not only help you design and select the right equipment, but also send people to guide the on-site installation and commissioning. Once the equipment is running, we’ll also teach you step by step how to operate and maintain it.
If you run into any technical issues or require maintenance later, we’ll be there to support you anytime to ensure the smooth operation of the entire line. You just focus on production; leave the rest to us.
6. How long does it take to build and get the production line up and running?
+
The construction timeline depends largely on the scale of your project.
For a small production line, usually, everything from design to installation and commissioning can be finished in a few weeks to a month or two.
For medium to large ones, it might take around three months. We’ll work out a specific timeline based on your specific plan, and our team will monitor the entire process. You’ll know exactly how things are progressing at each step, so no need to worry about delays.
7. What raw materials can the production line process? And what types of fish feed can it produce?
+
Our fish feed production line can process a wide range of raw material. Common ones like corn, fish meal, soybean meal, wheat, and wheat bran are all fine, and we can also add supplementary ingredients flexibly as needed. The feed pellets produced can be floating, sinking, or slow-sinking. Whether you’re raising tilapia, grass carp, carp, or other fish, we can customize the pellet size and formula based on your fish’s feeding habits and growth stage, ensuring a more palatable and effective feed.
8. Can the production line be expanded or have automation modules added later?
+
Of course. Our production lines are designed with expansion in mind. You can start with a reasonable production volume and then upgrade to more automated modules, such as automatic batching and packaging. That way, the production efficiency gets a boost, and managing things becomes even easier.
9. Roughly how long is the investment payback period for building a fish feed production line?
+
The payback period depends on factors like output, raw material prices, and selling prices. Generally speaking, a small or medium-sized production line will recoup the investment in about a year, while larger ones may take longer. But with your own production line, you’ll have more control over feed costs and guaranteed quality. In the long run, the returns will only get more stable.
10. What are the benefits of a fish feed production line?
+
Owning your own fish feed production line means you take full control of the most critical aspect of aquaculture—nutrient supply. The benefits are direct and clear:
- You can source local ingredients directly, skipping middlemen and avoiding brand markups on commercial feeds. This slashes your cost per ton of feed significantly.
- Tailor formulas anytime for different species (grass carp, crucian carp, grouper, sea bass) and growth stages (fry, grow-out, broodstock). Customized nutrition boosts growth, strengthens disease resistance, and improves meat quality.
- From raw material procurement to processing, everything stays under your watch. You can eliminate poor-quality or banned additives, ensuring safe feed and trustworthy seafood products.
- Through controlled extrusion, feed pellets stay intact in water longer—reducing nutrient loss, cutting water pollution, and lowering the feed conversion ratio (FCR). Truly saving you money.
- You don’t have to worry about external feed price increases or stock shortages. You can flexibly adjust the formula based on market conditions. . Your fish will reach harvest size with better shape and higher prices, building your unique competitive edge.
