Working Principle in the Extrusion Chamber:

• Heating and moisture removal allow starch particles to gelatinize → becoming flexible and easier to shape.
• Compression and friction in the extrusion barrel create a dough-like “plastic mass” that is pushed through a die.
• A cutting blade shapes the material into the desired form before drying and cooling.
• Adjustable parameters: temperature, moisture, screw speed, ingredient ratio → determine floating ability, expansion, and nutritional value.

Single-Screw Extruder – Efficient single-screw extrusion solution:

• Robust design, continuous operation
• Energy-efficient
• Easy to disassemble and clean
• Uses V-belt or direct drive
• Low spare part costs
• Produces stable product quality, easy to control
• Compatible with various formulations (floating, slow-sinking, soft-shell feed, etc.)

Optional Upgrade – Expansion Control System (ECS):

• ECS controls product bulk density and expansion rate right at the cutter.
• Uses compressed air pressure to alter pellet expansion.
• Allows production of floating, sinking, hard-shell aquatic, bottom-sea feed…
• Ensures consistent product quality, adaptable to different animal feed lines.

Advantages of Extrusion:

• Optimizes nutritional value
• Reduces or eliminates antinutritional factors (ANFs)
• Produces uniform pellet shape
• Ensures uniform moisture and gelatinization
• Customizable to customer needs and product lines
