Guide to Wet Type Fish Feed Extruder
In aquaculture, feed quality often determines whether fish grow fast or not, and it also directly affects the income of farmers. That’s why many fish farms and fish feed mills are thinking: How can we make good pellets with comprehensive nutrition, easy digestion and not easy to disperse in water? The answer is clear: wet extrusion technology. Compared to traditional dry-processing, wet-processing fully gelatinizes the starch in raw materials and creates a more balanced protein structure. This makes the feed more easily absorbed by fish and ensures that the pellets are more stable in water, resisting breakage.
Free from complicated steam system, this compact fish feed machine offers easy controls anyone can master quickly. It produces feed: balanced nutrition, uniform in size, and easy to digest – helping animals grow faster and healthier. And its dry extrusion process means zero steam boiler requirements, reducing investment costs and running expenses. For fish farmers or fish feed mills with limited budgets and moderate production needs, the dry type fish feed pelletizer is the perfect choice.
At RICHI, we focus on developing fish feed equipment that stands the test of practical aquaculture. If you’re looking for a mature and reliable fish feed production solution to make high-quality feed suitable for fish and shrimp, try our dry type fish feed extruder — making good feed your own way.
How the Wet Type Fish Feed Extruder Works
If you’re curious about how it works, let’s first take a look at its components. This wet type fish feed machine primarily consists of a feeding device, conditioner, screw (you can choose how many screws), pressure chamber, forming template, cutter, and a drive and control system.
After understanding these parts, let’s follow the process step by step to see how raw materials are transformed into fish feed.
When it’s running, first you feed in the raw materials mixed according to the formula. Steam warms them up and adds moisture, making the materials soft. Then the screw pushes the softened stuff into a high-temperature, high-pressure extrusion chamber. That’s when the starch starts to gelatinize and the protein changes – the loose raw materials slowly blend into a smooth, thick mixture.
Next, this mixture gets squeezed through the die under pressure, turning into continuous feed strips. Just after leaving the mold, the internal pressure drops suddenly, and the moisture turns into steam and escapes, making the feed pellets soft and porous. Finally, a high-speed rotating cutter cuts these strips into pre-set pellets – and that’s your final fish feed.
The secret of the wet-process is how “steam conditioning” and “screw extrusion” work together. Steam fixes the problem of raw materials being too dry, avoiding the troubles of hard raw materials, energy consumption, and difficulty in forming with dry extrusion. Plus, high temperature and high pressure fully cook the raw materials. And by adjusting the die size, screw speed, and steam amount, you can easily control the pellet density and hardness – making floating, slow-sinking, or sinking pellets that work for all kinds of fish and shrimp.

Frequently Asked Questions
If you have any questions about extruders or feed production, you can first take a look at these answers.
I want to know which fish or other aquatic animals might be best suited for wet-processed feed?
+
Usually, aquatic creatures like tilapia, catfish, and shrimp are particularly well-suited for feed made by wet fish feed extruders. These species have higher requirements for feed digestibility and nutrition. The wet process, combined with steam treatment, makes the protein and fat in the feed easier to absorb while retaining more nutrients. This not only helps them grow better but also boosts farming efficiency – perfect for large-scale, commercial aquaculture operations.
I don’t know much about fish feed production lines. How can I choose the right machines?
+
If you’re not familiar with fish feed production lines, picking the right equipment can start with a few key points. First, be clear about your production needs: like whether you’re making sinking or floating feed, your daily output requirements, pellet size, and so on. Then, get to know what a full production line includes – things like crushing, mixing, pelletizing, drying, and packaging. Each step needs the right equipment to back it up.
Of course, if you really don’t know where to start, just tell our sales team. They’ll give you the best solution from a professional standpoint.
Which countries do you sell your products to?
+
Our wet type fish feed extruders have been exported to over 140 countries and regions, like the US, Canada, Australia, Russia, Mexico, India, the UK, Uzbekistan, South Africa, Afghanistan, Kenya, Tanzania, Algeria, Morocco, Sudan, Saudi Arabia, Malaysia, Indonesia, the Philippines, and so on.
Is this equipment difficult to operate? My staffs don’t have much technical backgrounds — can they learn?
+
We designed our wet fish feed extruder with ease of use in mind. It comes with an intelligent control system, featuring a straightforward interface and simple operations. Even non-technical staff can quickly get the hang of basic operations and daily maintenance after the professional training we provide. We also offer on-site guidance and remote technical support to make sure you and your team can get up and running smoothly, with complete peace of mind.
I’m worried about high operating costs. How does the wet process perform in terms of energy use and raw material utilization?
+
While wet type equipment does have slightly higher initial investment and energy use compared to dry type ones, it has clear advantages when it comes to feed quality, nutrient retention, and digestibility. Modern wet type extruders use energy-efficient technology – they can smartly adjust energy consumption based on production needs, avoiding waste.
At the same time, the wet process makes better use of starches and proteins in raw materials, boosting pellet formation rates and overall yield. That improves raw material utilization across the board. In the long run, this helps lower unit costs and boost economic returns.
How to confirm if this equipment is right for my business? Are there any success stories I can look at?
+
To make sure our wet type fish feed extruder fits your needs perfectly, we’ll first dig into the details of your farm—like what species you’re raising, the scale of your operation, your expected output, and so on. With that info, we can tailor a solution that’s just right for you. What’s more, we can arrange on-site visits or video calls so you can chat directly with our technical experts, get any questions answered, and see detailed equipment specs and simulated production data to help you make the best call.
As for case studies, we’ve done over 2,000 projects in more than 130 countries and regions, covering all kinds of farms—big and small, different types.
