When throughput capacity is limited by the residence time requirements in the extruder, a preconditioner is the solution. Clextral’s Evolum Preconditioner+ has key innovations that boost throughput and deliver exceptional production benefits: higher product quality, reduced energy, greater flexibility, and improved control.
A key benefit of the Preconditioner+ is the Advanced Filling Control device (AFC) that optimizes the residence time within the preconditioner to intensify the pretreatment of the raw materials with heat and moisture to create gelatinization. Product temperatures are quickly increased to setpoints with steam injection through strategically located zones to ensure full product absorption. Variable speed operation ensures flexibility for controlling residence times as required for different pet food formulations.
The preconditioner is easily adapted to both single-screw and twin-screw extruders used in pet food processing and can be retrofitted with existing plant equipment.
