DENSITY CONTROL SYSTEM

Product catalog summary

Overview: The document outlines Clextral's advanced density control system designed for the production of floating or sinking aquafeeds. This system allows for precise control over pellet density, ensuring consistent product quality and adaptability to specific species and farming conditions.

Key Features:

Accurate density control for consistent product quality.
Capability to produce high-density feeds (>650 g/L) for specialized applications.
Efficient recycling of steam and fines in the preconditioner, enhancing sustainability.
Flexibility to adjust product density from 350 g/L to 750 g/L at the extruder outlet.

Precision Density Control System: This system allows producers to set cooking intensity and control product density to meet customer specifications. It uses controlled steam addition or vacuum generation to achieve accurate density and expansion for high-quality pellets.

Performance Advantages: The system includes a vent stuffer integrated on a degassing barrel module, enabling seamless operation.

Target Bulk Density for Finished Pellets:

Fast sinking: > 640 g/L in seawater, > 600 g/L in freshwater.
Slow sinking: 580 – 600 g/L in seawater, 540 – 560 g/L in freshwater.
Neutral buoyancy: 520 – 540 g/L in seawater, 480 – 520 g/L in freshwater.
Floating: < 480 g/L in seawater, < 440 g/L in freshwater.

Certifications:

ISO 9001:2015 for Quality Management.
ISO 14001:2015 for Environmental Management.
