1. What Is a 500 kg/h Twin Screw fish feed making production line?

A 500 kg/h twin screw fish food pellet making production line is a medium-scale aquaculture feed manufacturing system designed to produce floating or sinking fish feed pellets through twin screw extrusion technology. The line integrates crushing, mixing, extrusion, drying, cooling, and packaging to achieve stable continuous fish feed production for commercial aquaculture farms and feed businesses.

2. Why 500 kg/h Capacity Is Important?

A 500 kg/h production line is positioned between small farm equipment and large industrial feed factories.

In real production terms:

around 4 tons of feed output per 8-hour working day

suitable for regional aquaculture feed supply

supports stable commercial feed production without excessive investment pressure

3. Why Twin Screw Technology Matters?

Twin Screw Advantage in Fish Feed Production

Compared with single screw systems, twin screw extrusion provides:

• stronger material mixing performance
• more stable pressure during extrusion
• improved floating pellet expansion
• better adaptability for high-protein formulas

4. Core Structure of the 500 kg/h Complete Feed Expansion Production Line

1. Raw Material Crushing System

Raw materials such as maize and soybean meal are ground into fine powder.

Purpose:

improve extrusion efficiency

stabilize pellet texture

2. Feed Mixing Machine

Ensures uniform blending of:

protein materials

starch sources

vitamins and additives

3. Twin Screw Fish Feed Extruder

This is the core machine of the line.

Inside the extrusion chamber:

materials are cooked under pressure

starch gelatinization occurs

pellets expand into floating structure

Key result:

stable floating fish feed pellets with uniform density

4. Drying System

Fresh pellets contain high moisture.

Drying helps:

improve storage stability

reduce mold risk

strengthen pellet structure

5. Oil Spraying System

Adds:

fish oil

nutritional additives

flavor enhancers

6. Cooling and Packaging System

Cooling stabilizes pellet hardness before packaging.

Packaging system supports commercial distribution efficiency.

5. What Makes 500 kg/h Line Suitable for Commercial Aquaculture

Stable Production Output

Suitable for continuous daily production.

Better Feed Quality Control

Twin screw extrusion improves pellet consistency.

Flexible Pellet Size Adjustment

Supports different fish species and growth stages.

Suitable for High-Protein Feed Formulas

Important for tilapia and catfish farming operations.
