Structure of dry type floating fish food pellet extruder machine

 

 

1. Feeding System

• Feeding Hopper: For storage of ground raw material.
• Metering Motor: Drives the bottom auger for precision feeding control. Usually VFD-controlled for stepless speed adjustment.

 

2. Extrusion & Heating System

• Insulated Barrel Guard: A protective stainless steel housing designed to prevent thermal injury and minimize heat loss.
• Heating Elements: (Commonly known as Heater Bands). These surround the barrel to provide the necessary thermal energy for the extrusion process.

 

3. Cutting & Pelletizing System

• Pelletizing Unit: The cutting assembly located at the discharge end.
• Independent Cutting Drive: Features a dedicated motor. This allows independent control of pellet length regardless of the main screw speed-a key feature for high-quality production.
• Clearance Adjustment Handwheel: For fine-tuning the gap between the blade and the die face to ensure clean, burr-free cutting.
• Slide-away Rail: Allows the operator to slide the cutter assembly aside effortlessly for die changes or barrel maintenance.

 

4. Control & Discharge System

• HMI / Control Panel: Centralized operation console for motors and multi-zone temperature control.
• Product Discharge Chute: Directs the extruded pellets to the next stage (cooling or packaging).

Why Choose an Extruded Fish Feed Machine? 

 

• Starch Gelatinization (Degree > 90%): High temperature and pressure during extrusion break down complex starches, making them 100% digestible for fish.
• Long Floating Time: Our Dry Type floating fish feed making machines produce feed that can float for over 12–24 hours without dissolving, reducing water pollution and feed waste.
• Pathogen Sterilization: The process reaches 120°C-150°C, effectively killing Salmonella and harmful bacteria, ensuring biosecurity for your farm.
• Wear-Resistant Components: We use Alloy Steel (38CrMoAl) for screws and barrels, extending the service life to over 2,000 hours of continuous operation.

 

 

 

Common Raw Materials for Fish Feed

 

To achieve the best expansion (puffing) effect, the raw material must be ground to 60-80 mesh.

• Protein Sources: Fish meal, soybean meal, peanut cake, poultry meal.
• Energy Sources (Starches): Corn flour, wheat flour, rice bran (Starch content should be 20%-30% for better floating).
• Fiber/Binders: Wheat bran, cellulose (Keep fiber < 8% to avoid fragile pellets).
• Additives: Fish oil, vitamin premix, minerals.

FAQ

 

Q1: What is the difference between a Dry Type floating fish feed pellet extruder machine and a wet Type floating fish feed making machine?
A: Dry type floating fish feed pellet making mill generates heat through friction and electric heaters (Cost-effective for small/medium farms). The wet-type floating fish feed pellet processing machine uses a Steam Conditioner to pre-cook the material, offering higher capacity and smoother pellets (Best for large-scale commercial production).

Q2: How do I control whether the feed floats or sinks?
A: It depends on the Formula (Starch content) and the Extrusion Temperature/Pressure. More starch and higher heat create a lighter, more porous structure that floats. By adjusting the screw configuration and moisture, we can also produce sinking feed.

Q3: What is the wearing life of the screw and die?
A: With our high-quality alloy steel, the Screw usually lasts for 800-1,200 tons of production, and the Die for 500-800 tons, depending on the abrasiveness of your raw materials.

Q4: Does the floating fish feed pellet extruder machine require an engineer for installation?
A: For small Dry Type dog food pellet extruder machines, we provide detailed video tutorials and 24/7 online support. For large-scale production lines, we can dispatch engineers for on-site commissioning and staff training.
