Wenger extruders - single screw and twin screw - produce the full range of petfoods and specialty animal feeds including dry expanded, soft-dry, soft-moist, semi-moist and co-extruded and novelty products in an almost endless array of controlled shapes, sizes, colors and textures.
Other feeds that are efficiently produced on Wenger systems include cooked grain, full fat soys, fish feeds, pig feeds, mink and fox feeds, and laboratory and zoo animal feeds.
Advantages of the Wenger extrusion cooking process for petfood and feed production include:
- Density control for dry expanded and semi-moist feeds. By controlling the expansion of the extrudate, the finished product may be regulated to produce products of optimum density, texture and shape.
- Reduction in Formulation Costs. Nutritionally complete feeds are produced at reduced ingredient costs due to the ability of the Wenger Extruder to produce nutritionally superior diets from a greater variety of raw ingredients.
- Increased Palatability. Product palatability and conversion rates with extrusion cooked feeds are traditionally higher than those of other feeds. Wenger extruders permit increased control over starch gelatinization, digestibility of the raw materials, and more complete utilization of the feed.
- Greater Versatility and Throughput. Wenger extrusion cooking systems utilize a combination of synergistic energy sources - electrical, steam and water - to produce the highest quality products at greater capacity and efficiency than any other extrusion or pelleting process. Wenger manufactures extrusion systems for specialty feeds with capacities ranging from 0.5 tonne to 25 tonne per hour.
- Higher Production Efficiency. Because of Wenger's extensive and continuing research towards equipment and process improvement, Wenger extrusion systems are able to handle a wider range of raw materials and processing conditions more efficiently.
The range and versatility of these processing conditions, will typically exceed those claimed for non-Wenger extruders or processes.
