Characteristics of protein raw materials

Fish and meat meal are concentrated protein sources — they require precise processing for maximum digestibility and pellet hardness.

💧
Moisture
6 – 10%
Fish and meat meal are dry materials < 10% moisture. For extrusion, steam or water is added up to 18–22% for plasticity.
🔬
Protein
55 – 72%
Fish meal has 60–72% protein — the highest in livestock nutrition. Meat meal 50–60%. Essential amino acids.
🌡️
Temperature
90 – 130°C
Extrusion at 90–130°C sterilises the material and activates protein binding. Lower temperatures for starter pellets.
🫧
Floating Pellets
0.6 – 0.95
Pellet density is controlled by expansion during extrusion. Floating pellets for carp and trout — easy feeding observation.

💡 Key advantages

  • Fish meal = the highest quality protein source
  • Extrusion produces floating pellets for aquaculture
  • Material sterilisation during the process
  • Precise density and pellet shape control
  • Suitable for starter, grow-out and finisher phases
  • High market value — high ROI

Processing technology

From dry meal to floating pellets for fish farms — precise extrusion and drying.

1

Grinding and sieving

Fish and meat meal are ground to granulation < 0.5 mm. Fine fraction is key for hardness and digestibility of small pellets.

2

Mixing recepture

Precise dosing of all components — proteins, starch, oil, vitamins and minerals. Mixers guaranteeu homogenost.

3

Steam conditioning

Introduction of steam increases moisture to 18–22% and heats the mixture to 80–90°C. Activates proteins before entry into the extruder.

4

Extrusion

The extruder compresses material and heats it to 90–130°C. At the outlet, expansion forms a floating or sinking pellet.

5

Drying and cooling

Carousel dryer dries pellets to < 10% moisture. Rotary Cooler stabilises temperature and final pellet hardness.
