Floating Fish Feed Extruder Machine


Product Overview
The premium DGP series floating fish feed extruder machine integrates a variable frequency feeding mechanism with genuine Siemens motors to deliver highly stable operations. This equipment conditions raw materials with moisture and steam before using high-temperature extrusion to shape the feed mixture properly. It creates diverse pellet sizes from 1mm to 12mm and allows easy adjustments to produce both floating and sinking feed varieties. The finished pellets float on the water surface for over twelve hours. This thorough cooking process ensures easy digestion for fish while minimizing water pollution inside your aquaculture ponds.
Capacity: 0.2-1.0 T/H
Power: 37-90 KW
Technical Structure of Floating Fish Feed Extruder Machine
This robust extruder machine for fish feed utilizes a precise steel frame structure to combine a high-capacity conditioner, a wear-resistant alloy main engine, and an intuitive electrical control system seamlessly.
Technical Parameters
The following production data is measured based on standard corn, soybean meal, and fish meal formulas using a fish feed pellet extruder, and your actual capacity may vary slightly depending on ingredient moisture and specific recipe ratios.

| Model | Main Motor Power (Kw) | Feeder Power (Kw) | Cutting Power (Kw) | Screw Diameter (mm) | Overall Dimensions (mm) | Production Output (TPH) |
|---|---|---|---|---|---|---|
| DGP-90B | 37 | 0.75 | 0.55 | 90 | 2100*1450*1350 | 0.2-0.4 |
| DGP-120B | 55 | 2.2 | 1.1 | 120 | 2400*1950*1600 | 0.5-0.6 |
| DGP-160B | 90 | 3 | 1.5 | 160 | 3100*2650*1800 | 0.8-1.0 |

Buyer’s Guide & Support Center
All your questions are answered here! Below are answers to frequently asked questions about the floating fish feed extruder machine, providing you with comprehensive answers.
How should a beginner select the most appropriate machine model?
→
You can easily determine the right configuration based on your current pond scale and daily feed consumption targets. Small facilities requiring under 500kg per day find the DGP-90B highly efficient, while medium farms needing 500-800kg achieve excellent results with the DGP-120B model. For larger commercial bases, our DGP-160B delivers the ideal hourly output, and our team will gladly evaluate your raw ingredients to recommend the most practical asset.
What are the specific requirements for the incoming raw materials?
→
The machinery processes diverse ingredients smoothly when the raw materials are ground down to 80-100 mesh and maintain a moisture level between 12% and 14%. It is important to ensure that the mixture remains free of metal fragments or large stones to protect the internal parts. Additionally, keeping the starch content between 25% and 40% helps the extrusion process create a perfectly buoyant pellet structure.
What causes the finished feed pellets to have a short floating time?
→
Short floating times usually indicate that the recipe lacks sufficient starch, contains too much moisture, or the processing temperature did not reach optimal levels during extrusion. You can easily improve buoyancy by adding a bit more corn to the mix, keeping the raw moisture strictly within 12% to 14%, and letting the chamber reach 120-140℃. These minor adjustments will restore the desired spongy matrix.
Can this equipment produce both floating and sinking feed varieties?
→
Yes, this versatile machine allows you to switch between floating, sinking, and slow-sinking feed types depending on your specific aquaculture demands. Operators can achieve these different buoyancy characteristics by adjusting the formula moisture, altering the screw rotation speed, and installing appropriate discharge molds. This flexibility allows a single investment to serve multiple fish species across different seasons perfectly.
What is the actual cost of a small electric fish feed extruder?
→
Our fish feed extruder machine price are highly affordable, with smaller models starting at just a few thousand dollars depending on your required configuration. This price offers a very practical investment for farmers who want to eliminate their reliance on expensive commercial feed brands. Operating costs remain low, making it an excellent asset for small businesses, and we provide a clear price breakdown with no hidden fees.
Do you provide professional installation support and technical training?
→
Yes, RICHI Machinery supports your project through complete workshop layout planning and professional field guidance during the installation phase. Our experienced engineers will visit your site to assemble the machinery and calibrate the initial processing parameters for optimal performance.
