PetFLEX™ Maximum Flexibility for Pet Foods and Treats

Wenger's PetFLEX extruders use a unique screw configuration to create processing zones that allow for the optimal balance of shear and thermal energy transfer.  This results in stable, uniform production of a wide variety of foods and treats -using traditional and novel ingredients - without “surging” that often happens with single screw designs.  PetFLEX also enables fresh meat inclusion as well as other inclusions to improve nutrition, palatability, and visual appeal.

Producing High Fresh Meat Content Kibble

Wenger's Thermal Twin Extrusion technology is the most effective and proven system to produce kibble with high fresh meat inclusion. 


The Thermal Twin's creative screw geometry, along with an innovative method of high steam injection, allow recipes to be cooked more gently - in a thermal manner – as opposed to an aggressive high shear method found in traditional extruders.


Post extrusion, the Wenger process utilizes specially designed die hoods and takeaway conveyors to preserve the quality of the fragile kibble. The patented Convection Roaster (CVR) begins drying while continuing the gentle thermal cooking process.  These actions strengthen the kibble so it can survive future processing steps, and help create a highly palatable product.


Pet foods with high levels of fresh meat used to be considered impossible to manufacture on a large scale. Now they are commonplace in the global market thanks to the Wenger Thermal Twin System.

Auto Density Control


Auto Density Control integrates three existing process components to provide automatic control of wet bulk density. It automatically measures product density and adjusts the process to maintain the desired density specifications.

  • Programmed to collect and analyze a sample as often as 45 seconds
  • Automatically adjusts the process to reach a new density setting in as little as 2 minutes
  • Decouple personnel from the product for greater food safety
  • Provide validation data for the process via the data display and recording capabilities of the system

Auto Density Control consists of three basic components:

  • Source Technology sampling and bulk density measuring device (BDS)
  • Wenger Automated Process Management (APM) system
  • Wenger Back Pressure Valve (BPV) mounted on the end of the extruder to control specific mechanical energy input
  • Auto Density Control can be installed as part of a new system or retrofitted into a system that already has at least one of the basic components.

Pet Treats

There are five basic categories of pet treats that can be produced using Wenger extrusion technology:

  • Expanded Treats
  • Un-Expanded Treats
  • Extruded Filled Treats
  • Co-extruded Treats
  • Chews (including dental care)

Unique Shapes?  Colors?  Fills?  No problem.


Whatever type of treat you're looking to make, Wenger's process experts can help you understand how to create it using proper extrusion cooking and drying processes.  This includes Wenger's unique knowledge of simultaneous, multi-color extrusion, and unique shaped dies to achieve the product you (and your customers) expect - with consistent quality.
