Wet Type Floating Fish Feed Extruder Machine – Industrial Grade For Large Aquafeed Production

 

Are you tired of low-quality floating fish feed that dissolves quickly, pollutes water, and causes massive feed waste?

Do you struggle with inconsistent pellet size, low digestibility, and high production costs in commercial aquafeed manufacturing?

 

For large-scale fish farms and feed mills, dry-type fish feed pellet extruder machines often fail to meet high standards-low starch gelatinization, poor water stability, and limited capacity lead to lost profits and stressed aquatic livestock. Many producers face unstable supply chains, overpriced commercial feed, and inability to customize formulas for different species. It's time to solve these pain points with a professional wet-type extrusion solution.

 

 

Our wet Type floating fish feed pellet extruder machine integrates steam pre-conditioning, precision extrusion, and variable-frequency control to produce high-quality floating, slow-sinking, and sinking aquatic feed pellets. By injecting steam into the conditioner, raw materials fully gelatinize under high temperature and pressure, improving pellet durability, water stability, and nutrient absorption. Designed for industrial continuous production, it supports wide capacity ranges (480–5000kg/h) and adapts to various raw materials (corn, soybean meal, fish meal, rice bran, etc.).

• Superior Steam Pre-Conditioning: Stainless steel steam conditioner ensures 90–95% starch gelatinization, 24+ hours floating stability without dissolution
• High-Wear Alloy Structure: Screw and barrel made of special heat-treated alloy steel, 3x longer service life, resistant to high temperature and abrasion
• Multi-Species Flexibility: Produce floating (tilapia/catfish), slow-sinking (mid-water fish), sinking (shrimp/crab/eel) feed by adjusting parameters
• Large Capacity & Energy Saving: 20–50% higher output than dry-type under same power, low energy consumption per ton, suitable for 24h continuous operation
• Precision Frequency Control: Variable-speed feeder and cutter, adjustable pellet length (0.8–12mm), uniform size, no burrs
• Easy Operation & Maintenance: Quick-disassemble structure, user-friendly PLC control, minimal cleaning time, reduced labor cost

Client: Nigeria Large-Scale Aquafeed Mill (10T/H Production Line)

 

Challenge: High dependency on expensive imported feed, low-quality local dry extruders with <10h water stability, inability to produce sinking shrimp feed

 

Solution: Installed our wet Type floating fish food making machine (model D-LX-175) with complete drying, cooling, and packaging lines

 

Results:

• Production capacity reached 10T/H, 60% cost reduction vs. imported feed
• Starch gelatinization 93%, floating stability 26h, feed waste reduced by 22%
• Successfully produced floating tilapia feed and sinking shrimp feed, expanding product lines and market share
• Customer comment: "This wet extruder transformed our business-we now control quality and costs, and our clients love the consistent, high-performance pellets."

 

 

 

Q1: What's the difference between wet and dry type extruders?

A: Wet Type fish feed extruder machine uses steam pre-conditioning for higher gelatinization (90–95%), better water stability, larger capacity; dry type relies on friction heat, lower cost for small-scale use.

 

Q2: Can this wet Type floating fish feed pellet mill produce both floating and sinking feed?

A: Yes-adjust steam, temperature, pressure, and die plate to switch between floating, slow-sinking, sinking pellets.

 

Q3: What raw materials can be used?

A: Grains (corn/wheat), soybean meal, fish meal, bone meal, rice bran, molasses, and various agricultural by-products.

 

Q4: What capacity models are available?

A: Standard models: 200–500kg/h, 500–1000kg/h, 1–3T/H, 3–5T/H, 5–12T/H; custom lines available.

 

Q5: How long is the warranty and service?

A: 12-month warranty, lifelong maintenance; 24/7 technical support, overseas installation and training.
