Feature / Category	Dry Type single screw floating fish feed pellet extruder machine	Wet-type single screw floating fish feed pellet machine	Impact on Production
Internal Fat/Oil Tolerance	Low (max 3% - 5%)	Higher (up to 10% - 12%)	High oil acts as a lubricant; too much oil in dry machines causes "slippage," stopping the cooking process.
Core Mechanism	Mechanical friction & shear generate 100% of the heat.	Combines steam injection (thermal) with mechanical shear.	Wet process allows for more precise temperature control.
Pre-Conditioning	None. Raw materials enter the barrel dry.	High-intensity steam conditioning (60-90 seconds).	Conditioning hydrates and pre-cooks the mash for better quality.
Moisture Content	Low: 12% - 18%.	High: 25% - 32%.	Higher moisture in wet extrusion is key to superior starch cooking.
Starch Gelatinization	60% - 80% (Partial).	90% - 95%+ (Comprehensive).	Higher gelatinization = better digestibility and water stability.
Output Capacity	Lower (limited by motor torque).	Higher (up to 30-50% more for the same motor).	Steam softens the material, allowing for higher throughput.
Wear & Tear (Parts)	High. Intense friction accelerates screw and barrel wear.	Lower. Steam acts as a plasticizer/lubricant, extending part life.	Wet extrusion reduces the frequency of costly maintenance downtime.
Energy Profile	High Specific Mechanical Energy (SME) from electricity.	Lower SME; balanced with thermal energy (steam).	Shifts the energy load to the boiler, which is often more cost-effective.
Water Stability	Average (15-30 minutes).	Excellent (several hours to 24h+).	Vital for aquafeed to prevent nutrient leaching in water.
Initial Investment	Lower (No boiler or steam piping required).	Higher (Requires boiler, conditioner, and piping).	Dry is better for start-ups; Wet is for professional commercial lines.
Pellet Density	Limited control over floating/sinking.	Precise control over buoyancy and expansion.	Necessary for specialized fish feed (floating/sinking/slow-sinking).

The floating fish meal making production line can produce feed pellets with diameters ranging from 1 to 9 mm.

 

1. Specialized Shapes

We offer custom mold (die) engineering to produce shapes that enhance brand identity and palatability:

• Pet Food: Hearts, Bones, Triangles, Stars, Rings (Donuts), Crosses, and standard Round/Pill shapes.
• Aquafeed: Perfect spheres for uniform sinking rates and cylindrical pellets for optimized feeding.

 

 

2. Product Categories & Types

• Floating Aquafeed: High-expansion pellets that stay buoyant for 24h+, ideal for Tilapia, Catfish, and Carp.
• Sinking & Slow-Sinking Feed: Precise density control for Shrimp, Salmon, and Trout.
• Professional Pet Kibble: High-protein, high-fat formulations for puppies, adult cats, and active working dogs.

 

 

 

 

Q1: How long does it take to switch between different pellet shapes?

Answer: Switching shapes requires a change of the extrusion die. Our Quick-Change Die System allows for a complete transition in approximately 15 to 30 minutes. This minimizes downtime and allows for small-batch production of multiple product lines within a single shift.

 

Q2: Can a single screw floating fish feed pellet extruder machine produce 1.0mm micro pellets reliably?

Answer: Yes, but it requires high-precision grinding of raw materials (at least 80-100 mesh) and a specific high-pressure die plate. For micro-pellets, we recommend the Wet-process system to ensure the starch is fully gelatinized, which prevents the small pellets from crumbling in water.

 

Q3: What is the maximum percentage of fresh meat or oil I can add?

Answer: In our Wet-type single screw floating fish feed pellet making machine, you can effectively process recipes with up to 20-30% fresh meat slurry and 8-12% internal fat. For higher lipid requirements, our lines are designed to integrate with [External Vacuum or Drum Coaters] to reach total fat levels of 25%+.

 

Q4: How do you guarantee the pellets won't fall apart in water?

Answer: Stability is determined by the Pellet Durability Index (PDI). By achieving 90%+ starch gelatinization through our steam conditioning process, the starch acts as a natural binder. This creates a durable matrix that maintains structural integrity in water for up to 24 hours, depending on the formulation.

 

Q5: Why is a cooling conveyor necessary before packaging?

Answer: Pellets exit the dryer at high temperatures. If bagged immediately, the residual heat causes "moisture migration," leading to condensation inside the bag and subsequent mold growth. Our [Cooling Conveyor] reduces the core temperature to within 3-5°C of ambient air, ensuring a shelf-stable product.
