WENGER AQUATIC FEED SYSTEMS
Wenger extruders produce the full range of feeds for catfish, shrimp, eel, trout, salmon, carp, perch, tilapia, milk fish, yellowtail, bream, bass, crawfish, frogs and other fresh water and salt water species.
Other feeds produced on Wenger systems include full fat soys, petfoods, piglet feeds, mink and fox feeds, and laboratory and zoo animal feeds.
Advantages of the Wenger Process for Aquatic Feed Production:
- Total Control of Pellet Density. Unique extruder features permit precise control of finished product density to produce either floating or sinking feeds. It is also possible to control the rate at which the product will sink.
- Greater Feed Stability in Water. Durability of feeds for bottom dwellers has shown stability of 12 hours without binders, 24 hours with the inclusion of binders. Floating feeds also exhibit superior durability and floating qualities.
- Superior Production Efficiency & Versatility. Premium quality aquatic feeds as small as 0.7 mm diameter to as large as 50 mm diameter are processed on Wenger systems. By optimizing combinations of energy sources - electrical, steam and water - Wenger systems permit the utilization of a wider range of raw materials than is practical for other processes.
- Higher Feed Energy Levels. The Wenger extruder allows up to 22% fat or fish oil to be incorporated into the feed during extrusion. Complementing this with post-extrusion external oil application can yield feeds with as much as 40% total fat for salmon and other aquatic species that benefit from such high energy feeds.
