EXTRUSION industrial applications, in particular because of the increased flexibility provided by the AFC. This variable speed device enables adjustments of the residence time as required to adapt the equipment to different types of recipes and to respond to the needs of multi-product extrusion lines. Moreover, this convenient design allows the system to start up when fully charged, even after prolonged downtime with a full tank, thanks to the new kinematic feature. In terms of hygiene and food safety, the Preconditioner+ is designed with minimal retention areas to facilitate cleaning. This feature is further enhanced by an integrated ‘quick recipe changeover’ function through the reversible AFC system, used here as a conveying screw that enables the entire tank to be emptied. These improvements in equipment cleaning capabilities and hygienic design are important advantages for food processing applications. Finally, the intensification of Clextral’s Preconditioner + offers improvement in the overall process, energy savings and enhanced quality of finished products, as well as greater flexibility and better control of operating parameters, whatever the recipe.
New range of twinscrew extruders
A daily task of aquafeed processors is ensuring the perfectly stable quality of the finished product despite daily variation in the characteristics of the raw materials. Clextral’s new EVOLUM + twin-screw extruders offer advanced technology that gives processors new levels of throughput, flexibility, and control while ensuring maximum product quality and process stability. A major innovation, the Advanced Thermal Control (ATC) is a self-learning, proprietary software solution to ensure absolute precision in temperature control. ATC continuously monitors production and adjusts to changes in parameters (characteristics of raw materials, recipes, throughput, etc.) to ensure process and product consistency. ATC is proven to enhance process stability up to 70 percent, with energy savings averaging 20 percent by eliminating excess heating/ cooling to maintain process temperature set points in any circumstances. The EVOLUM+ range has also been specifically built for more hygienic processing and food safety with ergonomic designs and open profiles that allow full machine access.
Improved response time and stability thanks to Advanced Thermal Control (ATC) proprietary innovation. Clextral continues to innovate with twin-screw extrusion systems that produce aquatic feed with a precise balance of proteins, oils and carbohydrates, processed for optimum digestibility with reduced waste. Clextral’s systems process a wide selection of recipes and raw materials and accurately control pellet density for specific product attributes, such as sinking and floating properties. With these innovations in preconditioner and extruder technologies, Clextral is helping aquafeed processors meet the process challenges of today and the future.
