Featured Snippet
To use a diesel single screw floating fish feed pellet machine efficiently:
- Prepare raw materials (60–80 mesh, 20%–25% moisture)
- Start the diesel engine and stabilize operation
- Feed materials evenly into the extruder
- Control temperature (120°C–160°C) and pressure for proper puffing
- Adjust die size and cutter for pellet shape
- Dry and cool pellets to below 10% moisture
This process ensures high-quality floating fish feed with good buoyancy, nutrition, and durability.

How to Operate a Small Floating Fish Feed Extruder Machine?
Why Choose a Diesel single screw floating fish food pellet maker machine?
In many aquaculture regions, especially where electricity supply is unstable or unavailable, diesel-powered fish feed machines provide a reliable and flexible solution. A diesel single screw floating fish feed pellet machine allows farmers to produce feed independently, ensuring continuous operation and stable output.
What Is a Diesel Single-Screw floating fish food extruder machine?
A diesel Single-Screw floating fish food extruder machine is an extrusion device powered by a diesel engine. It uses a rotating screw to process raw materials under high temperature and pressure, producing expanded floating pellets suitable for fish farming.
Key Features:
- Diesel engine drive for off-grid use
- Simple single screw structure
- Adjustable pellet size and floating performance
- Suitable for small and medium-scale production
Working Principle: How Floating Feed Is Produced
The machine works through a high-pressure extrusion process:
- Raw materials enter the extrusion chamber
- The screw compresses and heats the materials
- Starch gelatinizes under high temperature
- Materials expand instantly when exiting the die
- Pellets are cut into uniform sizes
This process creates internal air pockets, allowing pellets to float on water.
Raw Material Preparation: The Key to Feed Quality
Proper raw material preparation ensures stable production and high-quality pellets.
Common ingredients:
- Fish meal, soybean meal (protein)
- Corn flour, wheat flour (energy)
- Vitamins and minerals (nutrition)
Preparation requirements:
- Grinding fineness: 60–80 mesh
- Moisture content: 20%–25%
- Uniform mixing
Step-by-Step Operation Guide
1. Pre-Start Inspection
Check diesel engine oil, belt tension, lubrication points, and ensure all parts are properly installed.
2. Start the Diesel Engine
Run the engine at idle speed for 3–5 minutes, then gradually increase to stable working speed.
3. Feeding and Extrusion Adjustment
Feed materials evenly and adjust:
- Feeding speed
- Moisture level
- Die size
- Observe pellet quality to ensure proper expansion.
4. Pellet Cutting and Shaping
Adjust cutter speed to control pellet length and maintain uniform size.
5. Drying and Cooling
Dry pellets to below 10% moisture and cool them for safe storage and longer shelf life.
Key Operating Parameters
- Temperature: 120°C–160°C
- Moisture: 20%–25%
- Proper screw speed and pressure
- Balanced feed formulation
Advantages of Diesel Single-Screw floating fish feed pellet mills
