High-Efficiency Aquafeed Solutions
Industrial Floating Fish Feed Production Line
Advanced Twin-Screw Extrusion Technology for Tilapia, Catfish & Carp. Guarantees 100% Floating Rate (>24h) with zero water pollution and optimal digestion.
The Science of Floating:
Density Control
Traditional sinking feed often leads to overfeeding and water pollution because farmers cannot see if the fish are eating.
Loyal’s Twin-Screw Extruder solves this by creating a High-Expansion Structure. By instantly releasing pressure at the die head, the starch matrix puffs up, creating internal air pockets.
This process reduces the pellet density to <450g/L, ensuring 100% floatability for over 24 hours, even after water absorption.
100% Floatability
Pellets float on the surface for >24 Hours. This allows farmers to observe feeding behavior directly and stop feeding when fish are full, saving cost.
Zero Water Pollution
High-temperature extrusion creates excellent Water Stability. The feed does not dissolve or disintegrate into powder, keeping the pond water clear and reducing ammonia levels.
Lower FCR
The extrusion process cooks the starch (Gelatinization >90%), making it easier for fish to digest. This results in a lower Feed Conversion Ratio (FCR) and faster growth.
Process Flow Chart
From raw material grinding to automated packaging. A fully integrated system designed for high-efficiency aquafeed production.
01
Superfine Grinding
Raw materials (corn, soybean, fish meal) are pulverized to 60-100 mesh. Fine powder ensures a smooth pellet surface and better water stability.
02
Extrusion & Cutting
High-temperature twin-screw extrusion expands the pellets instantly. The die-face cutter shapes them into uniform floating balls or cylinders.
03
Multi-Layer Drying
Pellets pass through a multi-layer belt dryer. Moisture is reduced from ~25% to <10%, locking in the lightweight structure for floating.
04
Oil Coating
Post-coating drum sprays fats and vitamins onto the dried pellets. This boosts energy levels without affecting the puffing degree.
05
Cooling
Pellets are cooled to room temperature (+3°C) in a counter-flow cooler. This hardens the pellet surface, making it durable for transport.
06
Auto Packing
Finished feed is screened to remove dust, then automatically weighed and packed into bags (5kg-50kg) ready for market distribution.
Core Machinery for Floating Feed
Producing 100% floating pellets requires precise control over starch gelatinization and expansion. Our core equipment is engineered specifically for these critical parameters.
The Expansion Engine
Twin-Screw Extruder (DSE Series)
The heart of the floating line. Compared to single-screw, our twin-screw design provides better mixing shear and self-cleaning capabilities. It generates the high pressure needed to make the starch “puff” instantly at the die, creating the internal air pockets required for floating.
Wear-Resistant Alloy Screw
Steam Heating Barrel
Frequency Speed Control
Automatic Cutter System
Key to Floatability
Double-Shaft Steam Conditioner
Raw materials must be pre-cooked before extrusion. Our double-shaft conditioner injects steam to increase moisture and temperature, achieving a Starch Gelatinization rate of >90%. This is crucial: higher gelatinization = better expansion = better floating.
Stainless Steel Body
Adjustable Paddle Angle
Direct Steam Injection
Retention Time >30s
Structure Locking
Multi-Layer Mesh Belt Dryer
Floating feed is porous and holds moisture. Our dryer uses a 3/5/7-layer circulation system to gently reduce moisture content to safe storage levels (<10%) without damaging the pellet shape. Uniform drying ensures consistent density, preventing pellets from sinking later.
Steam/Gas/Electric Options
Auto Temp Control
Hot Air Circulation
Stainless Steel Belt
Multi-Species Compatibility
By adjusting the extrusion die and recipe, our floating line can produce specialized feed for various fish species at different growth stages.

Frequently Asked Questions
Answers about formulation, machine versatility, and operational costs.
Can this floating feed machine also produce sinking feed?
Yes, it is possible. The Twin-Screw Extruder is versatile. By lowering the screw speed, reducing temperature, and adjusting the recipe (less starch), you can produce high-density sinking pellets. However, for specialized high-protein shrimp feed, a dedicated Sinking Feed Line is more efficient.
Why does floating feed require starch?
Starch (from corn, wheat, rice) acts as the “framework” for expansion. Under high pressure, starch gelatinizes and creates a honeycomb structure that holds air bubbles. We recommend a minimum of 20% starch content to guarantee 100% floatability.
How do I add high fat/oil without affecting floating?
Adding too much oil before extrusion lubricates the barrel and reduces the shear force needed for puffing. The solution is Post-Coating. Our line includes a drum sprayer to coat oil after the pellets are dried, allowing for high energy content without compromising floatability.
Should I choose Electric or Steam heating?
For small capacities (under 500kg/h), Electric heating is simpler and requires less infrastructure. For capacities above 1 Ton/h, we strongly recommend a Steam Boiler. Steam reduces electricity costs significantly and provides better moisture conditioning for higher quality pellets.
What is the smallest and largest pellet size I can make?
Our standard dies range from 1.0mm to 12.0mm. Changing the size is simple: just stop the machine and replace the die mold on the extruder head. This allows you to feed fish from fingerling stage to adult harvest size.
