Solutions — Feed Milling
Commercial Aqua & Shrimp Feed Plants
Engineering next-generation extrusion plants engineered for supreme water stability, high fat coating precision, and superior pellet digestibility for both floating and sinking aquaculture species.
Advanced Extrusion Physics
High-Fineness Pulverization & Precision Density Control
Aquaculture species require highly specialized feeds. Fish demand exact density adjustments to generate either perfectly floating or slow-sinking pellets, whereas shrimp require dense, highly cohesive sinking feed with water stability exceeding 3 to 4 hours.
At Milling Equips, our aqua and shrimp feed plants utilize state-of-the-art co-rotational twin-screw extruders. We achieve starch gelatinization ratios exceeding 90% by applying fine raw material micro-grinding (down to 80-120 mesh) and utilizing our dual-diameter pre-conditioner (DDC) systems to secure complete nutrient assimilation and stable buoyancy.
Unrivaled water stability (>3 Hours)
Extrusion pellet sizing down to 0.6mm
Vacuum liquid coating (up to 25% fats)

Ultra-Fine Pulverizer
Shrimp possess simplified digestive tracts requiring exceptionally fine ingredients. Our micro-pulverizer processes components down to <150 microns to maximize nutrient uptake.
Vacuum Fat Coaters
Post-extrusion vacuum coater systems introduce lipids and liquid nutrients directly into the pellet's structural pores, ensuring zero leaching and maintaining clean pond water.
Modular Workflow
Aqua Extrusion Processing Modules
From precise micro-pulverization to automated vacuum coating, every module is designed to maximize pellet physical integrity and biological value.
01
Ultra-Fine Grinding
Pulverizing system reduces raw ingredients to sub-150 microns, guaranteeing highly cohesive particles essential for stable sinking pellets.
02
DDC Conditioning
Dual-diameter pre-conditioner introduces high-pressure steam and moisture, achieving >90% starch gelatinization prior to extrusion.
03
Twin-Screw Extrusion
Co-rotational twin-screws compress, shear, and cook the raw materials, utilizing real-time SME control to govern pellet expansion.
04
Vacuum Coating
Pellets are subjected to negative pressure vacuum chambers, infusing fats, vitamins, and enzymes deep into the core without structural damage.
