Fish Feed Extruder

A fish feed extruder isn't just a machine you plug in and hope for the best. Our product list covers everything from simple single-screw units for small farms to twin-screw fish feed extruder machine systems that handle 10+ tons per hour. Over the last fifteen years, one thing we learned early on is that a floating or sinking pellet line only works when the extruder matches your raw materials, local humidity, and target production volume. 

We've done projects in Vietnam where the customer needed high-fat floating feed for pangasius, setups in Norway focused on cold-water salmon diets, and lines in Nigeria producing affordable sinking pellets for tilapia. Each time, the fish feed extruder configuration changed—different screw profiles, barrel lengths, and preconditioning stages. You won't find generic "one-size-fits-all" recommendations here. We actually ask about your fish species, your local starch sources, and your existing drying or coating equipment before we even talk about pricing.

Complete Fish Feed Extruder Solutions

You can’t just buy any machine and hope for the best. Different fish, different farms, and different budgets all point to a specific type of fish feed extruder.  Some guys need a simple dry setup for floating carp pellets. Others need a complex wet system for high-density sinking feed. We supply them all.  We group our machines into six real-world categories based on what actually matters: screw configuration, moisture control, and pellet density. Below is the breakdown of the main types we offer, so you can see which one actually fits your production floor.

fish feed extruder plant

● SPHS Series 

Twin-Screw Extruder

This is the workhorse for serious operators. If you are making feed for species like sea bass, eel, or salmon broodstock, this model handles sticky raw materials like fishmeal, squid meal, and oil without clogging. It gives you perfect control to make pellets from 05mm (for fry) up to 25mm. It’s also your only option for slow-sinking diets that stay suspended in the water column.
Dry Type Fish Feed Extruder

● The Plug-and-Play DGP-Series

Dry Type Fish Feed Extruder

This is for the smaller farm or startup that doesn't have a steam system. You mix your powder, add water, and the machine does the rest using friction heat. It mainly produces basic floating fish feed for common carp and small pond fish. Particle sizes usually run 1.5mm to 8mm. It’s simple, but the output is lower, and pellets might be a bit rougher than wet extrusion.
Wet Type Fish Feed Extruder

● The Precision DSP-Series

Wet Type Fish Feed Extruder

When you need that "professional bag" quality, you go wet. This machine adds preconditioning steam to cook the starch fully before extrusion. It’s ideal for high-value shrimp feed, marine juveniles, and trout. You get silky smooth pellets, excellent sinking control, and sizes ranging 0.5mm to 15mm. Yes, you need a boiler, but the pellet quality is night and day compared to dry machines.
Fish Feed Pellet Making Machine

● The Ring Die SZLH-Series

Fish Feed Pellet Making Machine

Not every farm needs an extruder. Sometimes you just need a reliable ring die pellet mill with extra steam conditioning. Adding a double or triple conditioner gives you longer retention time—meaning the mash gets properly cooked before it even hits the die. This is a game changer for sinking fish operations running high-output lines.
Floating Fish Feed Extruder machine

● The Floating King Series

Floating Fish Feed Extruder machine

A floating fish feed extruder is really about die design, screw configuration, and moisture flash-off at the die face. This type works best for surface-feeding fish: tilapia, trout, bass, catfish, carp, and ornamental koi. Pellet diameters from 1.5mm to 12mm, with expansion ratios between 1.2 and 1.8.
Sinking Fish Feed Extruder machine

● Agricultural Waste Valorization

Sinking Fish Feed Extruder machine

Sinking feeds are trickier than floating ones because you want density without over-cooking the starch. A sinking fish feed extruder runs with lower screw speed and different die plate geometry—sometimes a vacuum system to pull air out of the melt. This extruder is for bottom feeders and mid-water species: shrimp, prawns, lobsters, crabs, eels, and sturgeon. Pellet sizes go small: 0.5mm for post-larvae shrimp up to 6mm for adult eels.
Single Screw Extruder machine

● Classic DGP/DSP Series

Single Screw Extruder machine

For 80% of fish farmers, this is the sweet spot. It’s perfect for  tilapia, catfish, and carp operations. You run standard recipes with soybean meal, corn, and wheat flour to make stable floating pellets from 1.5mm to 12mm. It won't handle super high fat or tricky feather meal, but for daily volume on a budget, it’s hard to beat.

What's Inside Our Fish Feed Extruder

Siemens Drive Motor

Dual-Stage Conditioner

This is where gelatinization happens. Dual-shaft paddles mix steam evenly into your meal – no cold spots, no raw starch slipping through. Feed quality gets locked in right here.

Forced Feeder System

Siemens Drive Motor

We don't skimp here. The Siemens motor keeps torque steady even when sticky dough tries to slow things down. Less heat, less noise, and it won't quit mid-shift.

Advanced Ring Die Design

Co-Rotating Twin Screws

The new fully wear-resistant alloy (38CrMoAi) screw and the inner sleeve of the bimetal expansion cavity can effectively reduce the wear and tear and ensure the long-term stable operation.

Stainless Steel Feeding System

Precision Feeder

Overfeed and you'll choke the barrel. Underfeed and you'll burn the product. This unit talks to the main drive – ingredient flow stays locked to screw rpm hour after hour.

We've been in enough feed mills to know exactly where extruders start showing weakness after six months of hard running. So we overbuilt those spots. Heavier bearing housings. Thicker barrel walls on the high-wear zones. We also designed the barrel sections to be easier to open...That's not marketing. That's just how we protect our reputation. Your extruder should make you look good to your customers. We build it so it does.

Technical Specifications & Parameters

capacity 200–400 kg/h

Model: DGP-90B

If you're running a modest fish feed line — say for local farming cooperatives or early-stage production — this dry extruder gets the job done without extra steam conditioning. It's straightforward, easier on the budget, and doesn't require a boiler. The 0.2–0.4 t/h range is ideal for hatcheries or small-scale commercial farms just getting into extruded feed.

Main motor power (kW) 37
Feeding power (kW) 0.75
Cutting power (kW) 0.55
Screw diameter (mm) 90
Overall dimensions (mm) 2100×1450×1350

capacity 500–600 kg/h

Model: DGP/DSP

Need half a ton per hour but don't have steam on site? This dry version keeps things simple. No boiler, no conditioning — just mechanical shear and heat. It's a common choice for fish farmers who want to produce their own feed without investing in auxiliary equipment.

Overall dimensions (mm) 2400×1950×1600 / 2600×1600×1900

capacity 800–1000 kg/h

Model: DGP/DSP

Once you cross 800 kg/h, single-screw extruders start showing their practical limits — but for many fish feed lines, that's still perfectly fine. The dry DGP-160B is a workhorse for producers who want maximum simplicity. The wet DSP-135B, gives you better thermal control and is what we typically recommend for fish feed where oil absorption and pellet durability matter more.

Overall dimensions (mm) 3100×2650×1800 / 3750×1980×1950

capacity 0.5–1.0 T/H

Model: SPHS75x2

This smaller model gives you the precision of intermeshing screws — better mixing, more uniform cooking, and tighter control over expansion — without the industrial-scale price tag. It's a solid fit for specialty feed producers making small batches of high-value aqua feed, like shrimp starter or marine fish diets, where pellet quality can't be compromised.

capacity 1.5–2.0 T/H

Model: SPHS120*2

Here's where things get serious. Once you cross one ton per hour, twin-screw starts making serious sense. This model handles floating and sinking feeds equally well, and the dual-screw design eliminates the surging issues that sometimes plague single-screw machines at this output level. 

Main motor power (kW) 90

Differential conditioner power (kW) 11
Differential conditioner spec DC500*400-300

capacity 3.0–4.0 T/H

Model: SPHS120*2

This is where commercial fish feed production gets real. At three to four tons per hour, you're looking at supplying multiple farms or running a dedicated export operation. The twin-screw configuration gives you the thermal control and residence time consistency needed for high-fat formulations — think salmon feed with 20%+ oil inclusion. With a twin-screw, you get clean, stable pellets run after run.

capacity 5.0–6.0 T/H

Model: SPHS150*2

At five to six tons per hour, downtime becomes expensive, and consistency is everything. This larger twin-screw is built for continuous, heavy-duty operation — 200 kW on the main motor, differential conditioners, and specs that tell you this machine isn't playing around. It's the kind of extruder you'd find in a centralized fish feed plant supplying half a region.

Differential conditioner spec DC600*500-300

capacity 10–12 T/H

Model: SPHS185*2

This is the top end of our twin-screw lineup. Ten to twelve tons per hour means you're either a very large feed producer or you're running a toll manufacturing operation for multiple brands. At this scale, small efficiency gains translate into serious money. The 355 kW main motor, 185 mm screw diameter, and heavy-duty conditioner specs all point in one direction: nonstop production.

A cooperative in the Amazon region wanted to process their own corn and sorghum into floating feed for native pacu fish. No boiler, no trained technician – just a simple machine.

We sent a single-screw dry-type fish feed extruder. They run whole grain through it (pre-ground) and produce 0.5 t/h of floating 4mm pellets. They also use the same machine to expand corn for human breakfast cereal. Two products, one extruder. Very resourceful.

 
 

We don't just sell machines. We design and install complete fish feed extruder lines for farms and feed mills across five continents. Below are real projects from the last three years – each with different species, different raw materials, and different capacity needs. Some customers bought a single fish feed extruder machine. Most bought a full extrusion line including dryer, coater, and grinder. Read through these. You'll probably see your own situation somewhere here.

○ RICHI MACHINERY

 

A fish feed extruder alone won't run your plant. You need the whole line sized correctly for your ingredients, your building, and your budget. We design complete extrusion systems for different raw materials (corn, wheat, tapioca, fishmeal, soybean meal, rice bran, blood meal) and different applications (floating fish feed, sinking shrimp feed, pet food, even grain expansion).

Custom Extrusion Lines – From Raw Material to Bagged Feed

The standard process flow includes raw material receiving, grinding, batching, extrusion, drying, coating, cooling, screening, and bagging. But we constantly add or remove sections depending on the client's situation.

We handle the whole lifecycle – layout design, equipment fabrication, shipping, civil work guidance, installation, commissioning, team training, and wear parts supply for years to come. Every line we build is different, and that's exactly how we approach each project.

Real projects: a shrimp feed mega-plant in India (10 t/h), a salmon feed line in Norway (9 t/h), a carp feed factory in China (8 t/h). Includes everything in the 5-6 t/h line plus dual extruders (redundancy), centralized lubrication, advanced process control (SCADA), and option for rail car loading. These lines usually run 24/7 with three shifts.

Twin Screw Line

 
 
 

A fish feed extruder is only one piece. You need the whole line – grinder, mixer, dryer, coater, screener, bags. Below are complete production solutions we've priced and built for customers worldwide. The investment ranges come from thousands of actual quotes we've delivered, not guesswork. Each line is turnkey: equipment only (no civil works, no shipping). Your actual price depends on automation level, local voltage, material of construction, and add-ons like fat spray systems or extra silos. But these ranges will get you in the right ballpark – probably within 15% of your final number.

Complete Modular Systems for Fish Feed Plants

05/01

Cleaning & screening system

Raw Material Cleaning System

Gets rid of stones, magnetic metals, and dust before they wreck your hammer mill or damage extruder screws. Most common setup: a vibrating screen plus a magnetic separator.

05/01

crushing system

Raw Material Crushing System

Reduces grains and meals to the right particle size. Shrimp feed needs powder under 0.5mm. Tilapia feed can handle 1.0mm. We offer coarse grinders and fine-grinding classifiers.

05/01

fish feed mixing system

Batching & Mixing System

Weighs and blends your formula – fishmeal, soybean meal, wheat flour, oil, minerals. Manual or automatic batching. Ribbon mixers for general feed, paddle mixers for high-moisture or sticky formulas.

05/01

Drying system

Fish Feed Drying System

Fresh pellets right out of the extruder have 22–28% moisture. You need them down to 8–10% for storage. Belt dryers are the standard (gentle, even drying). Plate dryers are cheaper but less uniform.

05/01

Cooling system

Fish Feed Cooling System

Hot pellets straight from the dryer will sweat inside the bag – mold follows. A counterflow cooler pulls room air through the pellets, dropping temperature to near-ambient before bagging.

05/01

Liquid Addition & Spraying System

Fish Feed Coating (Spraying) System

Adds fats, oils, or liquid vitamins after drying. Basic systems use a drum sprayer. High-end shrimp and salmon lines use a vacuum coater – pulls oil deep into the pellet instead of just coating the surface.

05/01

Packaging system

Fish Feed Bagging System

Weighs and fills your bags automatically. Manual or fully automatic with a sewing head or heat sealer. Most mid-size plants choose the semi-auto version – fast enough for 6–8 tons per hour without the complexity.

05/01

Conveying system

Conveying System

Moves material between machines. Bucket elevators for vertical lift. Screw conveyors for horizontal or inclined transfer. Belt conveyors for fragile pellets that break easily.

05/01

Silo system

Storage & Handling System

Stores raw grains or finished pellets. Flat-bottom silos for large volume, hopper-bottom silos for complete discharge. We also supply aeration floors and level sensors.

Fish Feed Extruder FAQs

Dry-type starter lines run from around $20,000. A fully equipped wet-type twin-screw line with dryer, coater, and controls sits between $80,000 and $1,200,000 — capacity is the biggest driver. Those numbers come from real orders, not catalog pages. Tell us your daily output target and we'll put an actual figure in front of you.

Yes — and we make sure of it before we leave. Our technicians stay on-site until your operators can run the line confidently on their own. We also hand over illustrated manuals and layout drawings in your language. Most teams are fully independent within a week. The machine isn't the hard part; setup and first batches are. That's exactly where we focus.

One line handles both. Screw configuration and die plate selection control pellet density and size — switching between species takes under 30 minutes on most twin-screw models. We've run tilapia, catfish, carp, and pangasius through the same line in the same week. Just tell us your full species list upfront so we configure correctly from the start.

Take your monthly feed consumption, add 20% for herd growth, divide by 300 operating hours. That gives your minimum required output. Then go one size up — we've seen too many farms hit capacity limits within 18 months. Upgrading mid-production is painful and expensive. If budget allows, size up now.

Cassava works well — it's high-starch and great for floating pellets. Corn is straightforward. Rice bran needs attention; too much oil content causes die slipping and inconsistent output. We test your actual ingredients before the machine ships. If a formula won't work as-is, we tell you and suggest blending ratios that will. No surprises after delivery.

We stock wear parts — screws, barrels, dies — for every model we've shipped in the past decade. Parts go out fast. For troubleshooting, 90% of issues get resolved over a WhatsApp video call with one of our engineers. If it needs a site visit, we can have a technician there within two weeks. The warranty is 12 months, but the support doesn't stop there.

Factory. 60000 square meters in China. We manufacture extruders, dryers, coaters, grinders, and pellet mills under one roof — the full line, not assembled from third-party components. You're welcome to visit and watch your machine being built. Customers from over 60 countries have done exactly that.

For saltwater species like shrimp and abalone, yes — but it requires the right setup. Fine particle sizes under 1mm, precise moisture control, and a properly configured binding ratio. We've built shrimp feed lines in Ecuador and abalone lines in South Africa. Water stability above 90 minutes is achievable; it's just not something a basic single-screw machine will deliver.

Small lines under 1 t/h: 25–35 days production, then 5–7 days installation. Medium lines: 40–60 days. Large lines up to 10 t/h: 70–90 days plus 3–4 weeks on-site. Every Friday we send production photos — you always know where things stand. Custom alloy or automation upgrades add 2–3 weeks on top.

Short answer: some of them are fine for low-volume, simple recipes. But if you're running high-fat salmon feed, shrimp pellets, or anything above 1 t/h, the cheaper units tend to cause problems — inconsistent pellet quality, frequent die clogging, short screw lifespan. We've had customers come to us after those experiences. Fixing it mid-production costs more than buying right the first time. We're not the cheapest option. We are the one that keeps running.
