Aquafeed Solutions with Wet Type Fish Feed Extruder Machine
The wet type floating fish feed extruder machine produces high-quality floating pellets for commercial fish farms and feed manufacturers. Unlike dry type fish feed machines, it uses steam conditioning to improve cooking control, starch gelatinization, pellet expansion, and water stability. The VTSP-80 uses a single-screw extrusion system.
The VTSP series wet type fish feed extruder processes various aquatic feed ingredients into floating pellets for tilapia, catfish, carp, trout, shrimp and ornamental fish. It is mainly used in medium and large aquafeed factories, commercial aquaculture farms and professional feed production facilities.
During operation, raw materials are conditioned by steam and moisture before entering the extrusion chamber. By changing die molds and adjusting extrusion parameters, the machine produces floating pellets from 0.9 mm to 15 mm with excellent water stability. For small farms or businesses needing lower investment and simpler operation, our dry type fish feed machine is also available.
Dry Type vs Wet Type Fish Feed Extruder Machine
The wet type fish feed extruder is equipped with a conditioner and needs a steam boiler for conditioning. For more details, see Dry vs Wet Extruder Comparison.
| Feature | Dry Type Fish Feed Machine | Wet Type Fish Feed Extruder |
|---|---|---|
| Steam conditioning system | Not required | Required |
| Initial investment | Lower | Higher |
| Production scale | Small to medium production | Medium to large-scale production |
| Production capacity | Up to about 3 t/h | Up to 5 t/h |
| Pellet quality consistency | Good | More consistent for continuous production |
| Operation complexity | Simple operation | Requires professional operation |
| Suitable users | Small farms, startups and local feed producers | Commercial feed factories and large aquaculture farms |


When to Use Wet Type Fish Feed Extruder
| Application Scenario | Recommended Type | Reason |
|---|---|---|
| Large feed factory (>3 t/h) | Wet type | high output efficiency |
| High-quality aquafeed | Wet type | >90% starch gelatinization |
Why Adopt Wet Type Extruder (Advantages)
Advanced Conditioning Technology:
The steam conditioning system improves moisture distribution and cooking control before extrusion. The raw materials are conditioned by high temperature (130-150℃) boiler steam.
Premium Pellet Quality:
The final pellets by wet extrusion have a high-gloss, smooth surface and high structural integrity. The high temperature ensures the pellets are puffed and cooked deeply, improving water stability for more than 24 hours.
High temperature and high pressure can help reduce microbial contamination risks during feed processing.
Pellet Cutting and Size Adjustment:
It has a variable-speed, spring-loaded rotary cutter that precisely cuts pellets with clean cuts and smooth edges. The cutter can be adjusted to obtain different pellet diameters and lengths. Different die molds can produce different pellet shapes for pet food production. Final pellet size should be selected according to the size of the fish or shrimp being fed.


Working Process of Floating Fish Feed Extruder
Raw materials enter the feeding device and are pressed through the extrusion chamber. The material is then formed by the die mold and cut to the required length.
structure of Floating Fish feed extruder
1. Feeder:
It ensures uniform and stable feeding and adjusts the feeding quantity. A speed motor or frequency converter can be used to control the feeding speed.
2. Extruding chamber:
It consists of a screw, barrel, template and clamp. The screw and barrel are piecewise combined, allowing the compression degree to be adjusted according to the feed requirements.
3. The expansion mechanism
The expansion mechanism consists of feeding, compression and extrusion sections. The screw structure changes through these sections to transport, compress and extrude the feed material, with extrusion pressure up to 2–6 MPa and temperature up to 120-180°C.


Raw Materials for fish Feed Extruder machine
Raw materials include grain powders such as corn powder, flour, corn starch and rice bran, as well as meat meal, bone meal, fish meal and soybean meal. Before extrusion, the raw material should be 60–80 mesh with 20–25% moisture through high-temperature steam conditioning.
Spare Parts For Floating Fish Feed Extruder Machine
♦ The screw sleeve adopts a jacketed construction for hot steam or cooling water, allowing effective control of extrusion temperature.
♦ The removable cutting mechanism uses elastic knives that attach to the die plate and can be operated quickly and accurately.
♦ Screw rods and dies are processed through vacuum quench treatment with high processing precision and long service life.
♦ Due to high pressure, shear and abrasion inside the barrel, easily worn parts such as the barrel and screw need to be replaced periodically. The aquafeed equipment uses a modular design so worn components can be easily removed and replaced.
Additional Wear Parts Included
Each fish feed pellet machine is equipped with extra wear parts free of charge, including two sleeves, one screw, one cutting knife and three die moulds.
