DGP Series Dry Fish Feed Machine: Cost-Effective & Boiler-Free Production
The dry type floating fish feed pellet mill is an extrusion machine designed to produce floating aquafeed pellets for species such as tilapia, catfish, carp, trout, shrimp and ornamental fish.
Compared with wet type fish feed extruder that requires steam conditioning system and boiler, the DGP dry fish feed machine uses mechanical shear force, frictional heat, auxiliary electric heating and high-pressure extrusion technology which can generate processing temperatures of around 130-150℃ under suitable operating conditions, to promote starch gelatinization and produce expanded floating pellets without an external steam boiler. The final pellets can float on water for 12-24 hours in stability.
The floating fish feed pellet machine has production capacity ranging from 30 kg/h to 3 tons/h which is suitable for small fish farms, commercial aquaculture operations and small-to-medium feed manufacturers that require flexible production, simple installation and lower investment costs.
The floating fish feed pellet making machine can process various ingredients like corn, wheat, soybean meal, fish meal and other feed materials. By adjusting moisture content, formulation and die size, you can produce floating pellets with different diameters (from 0.9mm to 15mm) and water stability according to different aquatic species and growth stages.
The adjustable cutting system and interchangeable die molds allow production from small fry feed pellets to larger pellets for adult fish.
But if you want sinking pellets, we have another type of fish feed machine for making sinking fish feed pellets.
Dry Type vs Wet Type Fish Feed Machine
For those farmers who want to produce their own fish feed or start a small aquafeed business, dry type extrusion is usually a practical choice because it reduces equipment investment and simplifies operation. For more details you can check Dry vs Wet Extruder Comparison.

|---|---|---|
| Steam boiler | Not required | Required |
| Investment | Lower | Higher |
| Operation | Simple | More complex |
| Suitable users | Small and medium farms | Large feed factories |
| Production flexibility | High | High |
| Maintenance | Easier | More equipment required |

| Small fish farm (<1 t/h) | Dry type | low cost, no steam system |
| Cost-sensitive startup | Dry type | no boiler required |
Benefits and Advantages of Floating Fish Feed Pellet Mill
1. Improve Water Stability (12-24 Hours)
The highly expanded pellets can float on water surface for 12-24 hours and maintain their shape without dissolving. Fish farmers can monitor the fish-eating behavior easily, reduce feed waste 60–70% (depending on the initial level of management and the species of fish), and protect the aquatic environment from pollution. Puffed floating fish feed can reduce the pollution of water quality. It is extremely beneficial to environmental protection and to the growth of fish.
2. Improve Feed Utilization
The high-temperature, high-pressure process breaks down complex starches and fats, significantly boosting the palatability and nutrient absorption rate for aquatic species. The dust ratio of the final pellets is strictly controlled within 1%. In addition, due to the physical and chemical changes in the puffing process, the powder ratio of puffed feed is generally within 1%.
3. Versatile Output (0.9mm to 15mm)
You can produce a wide range of pellets diameters with a single floating fish feed machine (from 0.9mm micro-pellets for fry to 15mm for adult fish and pets), by quickly changing the die molds. The floating fish feed making mill has high efficiency, low power consumption. The floating fish feed pellet mill for sale can produce different shapes feed for fish, dog, cat etc.
4. Heavy-Duty Wear Parts:
The screw sleeve of this small fish feed making machine adopts an inlaid wear-resistant alloy steel strip structure, which can reduce greatly maintenance frequency and guarantee the fish feed making machine and parts a long lifetime with continuous operation.
How Does the floating fish feed pellet machine work
This floating fish feed pellet mill is the core of a complete fish feed production line, including a feed crusher, mixer, dryer, cooler, conveyor, packing machine, and other auxiliary equipment.
Step 1: Preparation and Feeding:
When you prepare raw materials based on the formulation, you need to crush them and mix them at first. You have to grind raw materials to 60-80 mesh for optimal extrusion effect, and control the moisture content between 13-18% strictly before feeding into the floating fish feed making machine.
Step 2: High Pressure Extrusion:
A specialized single screw mechanism presses and squeezes the powder materials at high speed, which generates the intense shear and frictional heating in the extrusion chamber. This temperature in the extrusion chamber can be 130-150°C which improves starch gelatinization and digestibility., denatures proteins, and effectively reduces pathogenic bacteria like Salmonella.
Due to the high-temperature and high-pressure processing conditions of floating fish feed pellet mill, the starch in the feed is matured, and the fat is more conducive to digestion and absorption.
However, you have to control the right temperature, because excessive temperature may lead to protein denaturation. And the final effect depends on the type of raw materials (e.g., fish meal, soybean meal), and the high temperature time. Long time high temperature may reduce amino acid utilization.
Step 3: Expansion and Forming:
The material undergoes instantaneous decompression within the mold cavity. When the materials come out from the die, they will instantly decompress, the internal moisture evaporates rapidly which expands the pellets into a porous and sponge-like structure to guarantee buoyancy.
Step 4: Precision Cutting:
There is an adjustable rotary cutter in the floating fish feed making machine, which can continuously slice the materials cleanly. Finally the materials turn completely into uniform round-ball type granules (floating pellets).
Raw Material for Floating Fish Feed Pellet Mill
The dry type fish feed pellet mill can process various raw materials and animal protein ingredients, including:
| Ingredient | Function |
|---|---|
| Corn / Maize | Provides starch and energy for floating fish feed production. |
| Wheat | Improves pellet binding and helps produce durable pellets. |
| Soybean Meal | Provides plant-based protein for aquatic feed formulation. |
| Fish Meal | Supplies highly digestible animal protein and nutrients for fish growth. |
| Rice Bran | Provides energy, fiber and additional nutrients. |
| Meat Meal | Adds animal protein to improve feed nutrition. |
| Fish Oil | Provides essential fatty acids for healthy fish growth. |
| Bone Meal | Supplies calcium and phosphorus for aquatic animal development. |
The final formula should be adjusted according to fish species, growth stage, protein requirements and local ingredient availability.
