Aquatic & Fish Feed Production Line Solution

Aquatic & Fish Feed Production Line Solution

1. Solution Overview

Our aquatic & fish feed production line is a customized feed processing system specially designed for aquaculture farms, fish feed factories and shrimp breeding enterprises, with a flexible output range of 1–20 tons per hour. This complete extrusion line can produce floating, sinking and slow-sinking fish & shrimp pellets, fully matching the feeding habits of fish, prawn, crab and other aquatic species.

Different from universal livestock feed equipment, the aquatic feed extruder adopts high-temperature extrusion technology, which effectively improves feed water stability, reduces water pollution and enhances the digestion & absorption rate of aquatic animals. We support full customization of the whole production line according to customers' target output, feed formula, workshop space and budget, and provide one-stop turnkey solutions for global aquaculture manufacturers.

3. Process Flow & Equipment Overview

Stage Equipment Function
1. Raw Material Receiving Dump pit, bucket elevator, screw conveyor, steel silos Receive and store grains, soybean meal, fish meal, and additives
2. Cleaning Process Drum screener, magnetic separator Remove stones, metals, and impurities to protect equipment
3. Grinding Process Ultra-fine hammer mill / air classifier mill Reduce raw materials to fine powder (60–100 mesh) for optimal aquatic digestion
4. Batching Process Automatic weighing system / dosing screws Precisely weigh each ingredient according to nutrition formula
5. Mixing Process Ribbon mixer / paddle mixer Homogenize all ingredients uniformly; add liquids and micro-ingredients
6. Conditioning Process Pre-conditioner / steam conditioner Heat and moisturize mixed flour for better extrusion performance
7. Extrusion Process Twin-screw extruder High-temperature, high-pressure extrusion to gelatinize starch and form pellets
8. Drying Process Fluid bed dryer / rotary dryer Reduce pellet moisture to safe storage levels (8–10%)
9. Coating Process Vacuum coater / liquid sprayer Apply oils, enzymes, attractants for enhanced nutrition and palatability
10. Cooling Process Counterflow cooler Cool coated pellets to ambient temperature for packaging
11. Screening Process Vibrating screen Remove fines and deformed pellets; recycle them back
12. Packaging Process Automatic packing scale, bagging machine, palletizer Weigh, bag (custom sizes), and palletize finished feed

4. Solution Core Advantages

4.1 High Water Stability, Reduce Breeding Cost

The twin-screw extrusion host achieves high-temperature sterilization and starch gelatinization, making feed pellets stay intact in water for over 2–6 hours. It avoids feed dissolution and water turbidity, cuts feed waste and lowers the cost of water treatment for aquaculture ponds.

4.2 Wide Customization Range for All Output Scales

We supply mini 1TPH small lines for individual breeding bases and large 20TPH full-automatic production plants for commercial feed manufacturers. Customers can freely choose automatic or manual configuration for batching and packaging links to balance labor cost and equipment investment.

4.3 One-Stop Customized Turnkey Service

We tailor the whole production flow, equipment matching and workshop layout based on customers' aquaculture varieties (fish, shrimp, crab, eel, etc.), feed raw material types and target hourly output. The whole line can realize automatic feeding, crushing, mixing, extrusion, drying, oil spraying, cooling and finished product packaging without excessive manual intervention.

4.4 Energy-Saving & Stable Long-Term Operation

All matched equipment adopts mature industrial processing technology and wear-resistant alloy accessories. The extruder barrel and screw have long service life, low failure rate and low power consumption, helping customers maintain stable continuous production and reduce later maintenance expenses.
