Grain characteristics

Maize and grain are the foundation of livestock farming — rich in starch and energy, suitable for various processing technologies.

💧
Moisture
10 – 14%
Ideal moisture for pelleting is 10–14%. For extrusion, water up to 18% can be added for plasticity and expansion.
Starch
60 – 75%
High starch content makes grains an excellent energy source. Extrusion gelatinises starch and increases digestibility.
🌡️
Temperature
80 – 140°C
Heat treatment destroys pathogens and improves digestibility. Extrusion at 120–140°C produces expanded pellets for aquaculture.
🔬
Binding
Starch
Starch in grains is a natural binder — corn and wheat produce firm pellets without additives. Ideal for fish pellets.

💡 Key advantages

  • Corn is the most available and cheapest raw material
  • Starch acts as a natural binder — no additives
  • Extrusion produces floating pellets for fish farms
  • High digestibility after thermal treatment
  • Suitable for pet food, livestock and aquaculture
  • Easily blended with protein supplements

Processing technology

From raw grain to finished pellets — adaptable process for animal feed, aqua feed and pet food.

1

Cleaning and preparation

Grain is cleaned of impurities — dust, stones and metal. An air separator removes the light fraction.

2

Grinding to flour

Hammer mill or flaking mill grinds grain to granulation < 2 mm. Finer fraction improves pelleting efficiency.

3

Mixing recepture

Flour is mixed with protein additives, vitamins and minerals according to the animal feed formula or pet food recipe.

4

Extrusion (fish feed, pet food) or Pelleting

For floating fish pellets an extruder is used. For animal feed and lucerne a pellet mill with flat die is used.

5

Drying and cooling

Extruded pellets have 20–30% moisture — the carousel dryer dries them to < 12%. The cooler then reduces temperature.
