Wenger Manufacturing, Inc. products

Wenger pioneered the use of twin screw extrusion cooking in the 1980's. Today, Wenger twin screw extruders can be found all around the world, producing a wide range of delicious and nutritious human foods, snacks, and ingredients; premium pet foods and treats; and high quality aquatic feed. With Wenger twin screw systems, the possibilities of what you can produce is endless.

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.

The Most Flexible Extruder Ever for Pet Food Production. Process traditional kibble, high fresh meat products, grain-free products, unique inclusions, and limited ingredient diets all from one .machine - at optimized throughput and quality - with no screw configuration change required.

Airflow II - The industry standard for post-extrusion drying/cooling. Wide variety of configurations, materials, and sizes. Horizontal and vertical dryers. 1-3 passes available. Heat source can be gas, steam, or electric. Adjustable air flows for optimal processing control and efficiency. Sanitary configurations available. Heated airflow from both sides of dryer. Heavy duty construction. Units are assembled and tested in our factory before shipped to ensure quality and performance. Technical assistance available 24 hours a day.

The Enhanaced Sanitary Dryer was engineered with a well-defined focus: increasing sanitation to the highest level possible. After thousands of hours of engineering and testing, Wenger is proud to offer the industry standard for sanitary, horizontal dryer design.

The Back Pressure Valve (BPV) is a bolt-on option for your Wenger extruder that enables increased control during start-up, shut-down, and normal process operation. Three valve functions in one device make it easy to regulate pressure and peform other necessary activities.

The Wenger Diverter Valve provides an effective and convenient way to divert wet material during the start up phase. This is especially helpful for textured protein applications. When the material quality and characteristics have been reached, the valve can be easily shifted to the open (process) position which provides optimal pressure and flow to the die.

The patented Wenger Vent Control System (VCS) is a heat exchanger designed to fit onto existing preconditioners to ensure important sanitation and operating functions including: Reduced condensation above the preconditioner. Elimination of pre-pasteurized fine particulates exhausting from preconditioner. Reduced risk of microbial contamination in environment around preconditioner. Reduced pressure in preconditioner that can create material buildup and poor flow. Patent pending.

The Wenger High Intensity Preconditioner (HIP) provides an advanced level of mixing and control that makes it the perfect complement to Wenger extruders.  Intensified mixing results in smaller particle sizes into the extruder, more uniform product moisture, and more consistent heating.
