Need High Water Stability and Precise Floatability in Your Fish & Shrimp Feed?
Aqua feed requires much finer particle size reduction and far higher water stability than land animal feed — if pellets dissolve prematurely in water, nutrients leach out and water quality in ponds rapidly deteriorates.
Premium Pulman's Aqua Feed Plant is built for ultra-fine micro-pulverizing, thorough precondition conditioning, and extrusion technology that produces floating, slow-sinking, or sinking feeds tailored to specific aquatic species.
Micro-Grinding & Extrusion Precision
Aqua feed production requires ultra-fine raw material grinding (typically down to 60-80 mesh) to ensure complete starch cooking during extrusion. Our plant integrates micro-pulverizers, differential diameter steam preconditioners, and high-shear twin or single screw extruders to achieve exact bulk density control for floating or sinking pellets.
Ultra-Fine Micro Pulverizer
Reduces raw fishmeal, soybean, and cereal grains to sub-250 micron size for superior pellet binding.
Pre-Conditioner Extruder
Injects steam and water to gelatinize starches, enabling floating or sinking feed expansion.
Multi-Pass Belt Dryer
Gently removes moisture from extruded aqua pellets to preserve oil coating and structural integrity.
Suitable for tilapia, catfish, carp, shrimp, and ornamental fish feed formulations.
Technical Specifications
Our Aqua Feed Processing Plants are configured for precise particle sizing, expansion density control, and oil coating. System components are fabricated in SS 304 / SS 316 for moisture resistance, with variable speed cutter drives to produce micro pellets down to 1.0mm diameter.
Floating (100% buoyant), slow-sinking & sinking pellets.
1.0mm micro feed up to 8.0mm fish pellets.
Over 12-24 hours stability without dissolving.
500 kg/hr to 10 TPH continuous extrusion lines.
Silent Features
Micro pulverizing stage ensures high starch expansion and water stability
Precise temperature and moisture control for floating or sinking feed
Vacuum oil coating system option for high-fat fish feeds
Stainless steel drying & cooling chambers prevent rust contamination
Uniform cutter geometry delivers clean, smooth pellet ends without fines
Working Principle
Fishmeal, soybean meal, and grain formulations are micro-ground in an air-swept pulverizer to ultrafine mesh. The fine mash passes into a differential DDC preconditioner where steam cooks the starch. Under high temperature and shear inside the extruder barrel, starch gelatinization expands the matrix. As feed extrudes through die orifices, high-speed cutters shape pellets which pass through a multi-pass dryer and cooler.
Why Choose Premium Pulman for Your Aqua Feed Plant
Aqua feed milling requires exact thermal and shear control during extrusion to produce buoyant or sinking feeds reliably. Premium Pulman has engineered specialized size reduction and process equipment in Vatva, Ahmedabad for over two decades. Our in-house testing facility allows you to trial your specific fishmeal and grain formulas prior to ordering.
