Thermal Twin Twin Screw Extruders

Removing Product Barriers

Our Thermal Twin Extruders remove product barriers and allow industry innovation by creating a new energy source through the increased use of steam injection.

  • Angled steam injector ports oriented in the direction of material flow
  • 4x more steam injection into extrusion zones
  • Up to 12% steam injection evenly distributed over the length of the barrel
  • 14:1 thermal to mechanical energy ratios
  • Operating costs nearly equal to single screw technology

Non-Conventional Products

Testing of Thermal Twin technology has consistently yielded products with more than 90% cook when the same products extruded on conventional extruders had cook values in the 80s. Yet, there has been no change in product density or palatability.

  • High Intensity Preconditioner

    The Wenger High Intensity Preconditioner (HIP) provides a level of mixing intensity that makes it the perfect complement to the newest Wenger extruders.

    • Two independently driven shafts offer speed and rotational direction control
    • Wide range of capacities and retention times
    • Three mixing intensity settings
    • More uniform hydration and heating of the recipe
    • Allows increased addition of meat slurries and other liquids in the recipe
  • Automated Mixing Intensity Control

    • Load cells take control of the process, including startup, shutdown and cleanout modes
    • Controls for temperature, moisture and shaft speed
    • Helps reduce waste at both startup and shutdown
  • Food Safety

    • Stainless steel hygienic frames and constructed with minimal seams for improved hygiene
    • Less horizontal surface area for product accumulation
    • Dust-tight downspout reduces fugitive dust in the transition from preconditioner to extruder
    • Hygienic Pneumatic Hood comes equipped with sampling port and sight glass for no-touch monitoring
