Thermal Twin Twin Screw Extruders

The premier solution for premium pet foods - especially those with high levels of fresh meat inclusion.

Wenger 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

Testing of Thermal Twin technology has consistently yielded products with more than 90% cook compared to values in the 80s when the same products were processed on conventional extruders - with no change in product density or palatability.

Thermal Twin Benefits

• Less costly energy source (vary input ratio of thermal to mechanical energy) – Lower SME
• Lower wear costs compared to other twin screw systems
• Less sticky products due to low shear
• Ability to achieve higher meat and other slurry levels
• More “natural” cooking (thermal energy) leads to development of new products
• Lower vitamin and trace mineral destruction
