Aquaculture Feed Processing Solutions

Cold Extrusion Technology for Maximum Bio-Availability and Water Stability

Protecting Your Formulation

In high-value aquaculture, such as larval feeds, medicated diets, and shrimp starter feeds, standard processing destroys value. High-heat manufacturing kills delicate ingredients, and standard pellets often lack the physical uniformity required for automated hatcheries.

At LCI Corporation, we specialize in Cold Extrusion and Spheronization. Unlike high-pressure cooking extrusion, our Twin Dome Extrusion process creates dense, sinking feeds without thermal degradation, ensuring the vitamins, enzymes, and medications you put in the mixer actually make it to the fish.

Precision Mixing and Homogeneity

Before extrusion, the formula must be perfect. In aquaculture, where medicated premixes or high-value enzymes are added in parts-per-million, standard blending is not enough.

If you're having challenges with segregation, micro-ingredient distribution, or liquid clumping we have solutions for you.

Our mixing technology creates a mechanically fluidized bed, ensuring a low Coefficient of Variation (CV).

Homogeneity: Achieves a low Coefficient of Variation (CV) quickly, creating the perfect "wet mass" required for the Twin Dome Extruder.
Result: A perfectly homogenous mash ready for processing.

Twin Dome Extrusion

For high-quality sinking feeds, the LCI Twin Dome Granulator (Extruder) offers distinct advantages.

If you're having challenges with heat damage, inconsistent density, or bridging / blockages we have solutions for you.

The Twin Dome system pushes wet material through a die at low pressure.

Zero Thermal Degradation: Operating at low temperatures ("Cold Extrusion"), the Twin Dome preserves 100% of the bio-activity of your ingredients.
Optimized for Spheronization: Unlike hard pellets, the Twin Dome produces uniform, malleable "noodles." These are the only extrudates physically capable of being spun into perfect spheres in the next step.
Handling Sticky Formulations: The twin-screw feeder design positively feeds sticky, high-fat, or high-moisture doughs that would bridge or plug other systems.

Spheronization: For The Hatchery

For hatchery, larval, and starter feeds, the shape of the feed is as important as the nutrition. LCI’s Spheronization technology transforms rough extrudates into perfect spheres.

If you're having challenges with water pollution, flowability, or coating efficiency, we have solutions for you. Using the LCI Marumerizer® Spheronizer, we convert wet pellets into smooth, uniform spheres.

Zero Dust: By rounding the edges, we eliminate fines, keeping water quality pristine for longer.
Uniform Size: A narrow size distribution ensures consistent feeding.
Ideal for Coating: The sphere has the lowest surface-area-to-volume ratio, ensuring high-value coatings adhere evenly and stay on the feed until consumed.
