Wet Type Floating Feed Making Machine

 

 

We offer two types of wet Type fish feed pellet extruder machines: single-screw and twin-screw models to meet different production capacities and feed formulation requirements.

Our wet Type floating fish feed pellet processing machine is widely used for producing high-quality floating and sinking aquatic feed pellets for fish, catfish, shrimp, crab, tilapia, and other aquatic species. Equipped with a steam conditioning system, it improves starch gelatinization, enhances pellet durability, and increases feed digestibility. The finished feed features a uniform shape, excellent palatability, high nutritional value, and a smooth surface. The floating or sinking performance of the pellets can be adjusted by changing the feed formulation and extrusion parameters. This wet-type fish feed extruder is an ideal solution for medium and large fish feed manufacturers, commercial aquaculture farms, and aquatic feed processing plants.

Key Advantages of Wet-Type Twin-Screw Floating Fish Food Pellet Maker Machines

 

1. High-Fat & Meat Inclusion: Effortlessly processes formulas with high fat (up to 22%) and fresh meat, where single-screw models typically fail.
2. Superior Homogenization: Twin-screw shearing ensures 100% uniform mixing, delivering consistent pellet color, density, and texture.
3. Self-Wiping & Easy Maintenance: The self-wiping screws prevent material buildup and eliminate the need for manual cleaning, significantly reducing downtime.
4. Micro-Pellet Precision: Produces high-quality pellets with smooth finishes, including micro-feeds as small as 0.5mm with high stability.
5. Buoyancy Control: Precise control over expansion ratios allows for easy switching between floating, sinking, and slow-sinking feeds.
6. Optimal Nutrient Bioavailability: Maximizes starch gelatinization and protein denaturation, ensuring high digestibility for premium pet food and aquafeed

Technical Comparison: 

 

Performance Factor	Wet-type Single-Screw floating fish feed pellet mill	Wet-type Twin screw floating fish feed production machine
Conveying Logic	Friction-dependent; prone to "barrel slip" with high-fat recipes.	Positive displacement; handles sticky, oily, or high-moisture mixes with ease.
Fat/Oil Inclusion	Limited to <10% (internal); higher levels cause loss of pressure.	Up to 22%+; ideal for high-energy premium pet food and meat-rich diets.
Mixing & Homogeneity	Basic mixing; potential for "dead zones" and uneven heat distribution.	Intensive shearing; ensures 100% uniform color, texture, and density.
Product Versatility	Standard pellets (1.0mm and up); limited geometric shapes.	Micro-feeds (0.5mm - 1.5mm), center-filled treats, and complex shapes.
Buoyancy Precision	Moderate; harder to maintain consistency between floating and sinking.	Precise density control; stable switching between floating, sinking, and slow-sinking.
Residence Time (RTD)	Wide distribution; some particles may be over/under-cooked.	Narrow RTD; ensures every particle receives identical thermal and mechanical treatment.
Cleaning & Maintenance	Manual teardown required; significant downtime for product changeovers.	Self-wiping screws; minimal residue, rapid cleaning, and faster changeover times.
Investment Focus	Lower CAPEX; optimized for high-volume, standard commodity feeds.	Higher ROI on Premium lines; essential for high-spec, specialized, or high-meat diets.

Technical Notes:

*Steam Generator Notice: This component is an optional auxiliary unit and is not included in the standard equipment package. It can be provided as an add-on or purchased separately based on your facility's steam requirements and local boiler regulations.

Standard Material: The default construction is heavy-duty Carbon Steel. Stainless steel (SUS304) options are available for food-grade applications or high-corrosion environments upon request.

Looking for a Different Solution?
While our wet Type floating fish feed pellet maker machines are the gold standard for commercial aquafeed, we also offer a complete range of Dry Type floating fish feed pellet extruder machines.

Dry-type fish feed production equipment is the ideal, budget-friendly choice for:

• Small-to-medium scale farm production.
• Processing full-fat soya, rice bran, or corn.
• Facilities without an existing steam boiler infrastructure.

Whether you need high-capacity steam-conditioned extrusion or a simple, friction-based dry system, we provide the right technology to match your specific production scale and budget.

Versatile Shapes & Multi-Species Application

Produce various shapes-rounds, triangles, bones, and hearts-using our quick-change precision dies. One machine supports diverse production:

• Aquafeed: High-stability feed for Tilapia, Shrimp, and Carp.
• Pet Food: Premium kibble for Dogs and Cats.
• Specialty Feed: Balanced diets for Birds and exotic animals.

 

 

 

 

 

Q1: What is the main advantage of a Twin-Screw floating fish feed extruder machine over a single screw floating fish feed pellet making machine?
A: The primary advantage is versatility. Twin screw floating fish food pellet maker machines feature an intermeshing mechanism that provides superior mixing and positive displacement. This allows you to process complex formulas with high fat content (up to 22%) or fresh meat, which would typically cause a single-screw machine to slip or clog.

 

Q2: Can I produce both floating and sinking fish feed with one machine?
A: Yes. By adjusting the expansion ratio through steam injection, screw speed, and die configuration, our wet Type floating fish feed pellet processing machines can precisely control pellet density. This allows for easy switching between buoyant (floating), slow-sinking, and fast-sinking feeds to suit different aquatic species.

 

Q3: Why is a "Wet-Type" extruder better for commercial feed production?
A: Wet-type extrusion utilizes a pre-conditioner to inject steam and moisture. This process achieves a higher degree of starch gelatinization (up to 90%+), resulting in better nutrient digestibility, improved water stability for pellets, and significantly reduced wear on the screw and barrel.

 

Q4: How many pellet shapes can be produced, and is it easy to change them?
A: Our machines support a wide range of pellet geometries, including rounds, triangles, hearts, and bones. Thanks to our quick-change die system, you can switch shapes in minutes by simply replacing the precision-engineered die plate, allowing for multi-product flexibility on a single line.
