WENGER CONTROL SYSTEMS
The WENGER Automatic Process Management System
As the pioneer in extrusion processing systems, Wenger continues to lead - bringing to the industry unique control system designs for even greater process efficiency. Through our experience and unrelenting commitment, we have developed the APM computer control system to provide Wenger customers the most up-to-date extrusion control system in the world.
Efficiently linking the operator to the extruder:
Man-Machine-Interface
The Man-Machine-Interface (MMI) is an IBM-AT compatible computer with control software program, a 21 inch VGA color monitor, and sealed membrane keyboard. The MMI Software runs under the Microsoft Windows Operating System. The computer is equipped with a hard disk drive, 1.44 MB, 3.5 inch floppy disk drive, and a tape backup drive.
The MMI functions as the efficient link between the operator and the machine, receiving input from the keyboard and displaying information on the monitor. The MMI also relieves the programmable logic controller of many time and memory consuming tasks. These include; alarm handling, formula storage and manipulation, color graphic generation and trending.
Reliably maintaining the extrusion process:
Programmable Logic Controller
The actual machine control is handled by a Programmable Logic Controller (PLC), chosen for its powerful control features as well as exceptional reliability, off-the-shelf availability, and worldwide service support. The PLC is configured with program memory and associated inputs and outputs. The PLC and its software maintains the real time control of the extrusion process, sequencing the startup and shutdown, and controlling the continuous process using information received from the MMI via a high speed digital communication link. Proportional-Integral-Derivative (PID) control is used to control all process variables.

With installations in production worldwide, the Wenger Automated Process Management System is a field proven, state-of-the-art control package engineered to automatically control start-up, operation, and shut down of the extruder. It will regulate extruder throughput, process temperatures, and liquids additions as well as monitor those integrated post-extrusion process functions required to optimize finished product quality, process efficiency, machine loading and personnel safety.
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 .8 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 35% total fat for salmon and other aquatic species that benefit from such high energy feeds.
WENGER SPECIALTY FEEDS SYSTEMS
Wenger extrusion cooking systems are being used the world around for the efficient production of petfoods and specialty animal feeds.
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 1.7 tonne to 22 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.
WENGER EXPANDED SNACK SYSTEMS
| Corn Balls | Onion Rings | Corn Curls | French Fries|
Corn curls, balls, tubes and rings marketed around the world by leading snack food companies are produced on Wenger extrusion systems. The Wenger snack system offers single supplier responsibility for the complete process in producing these expanded snacks--which are also known as direct expanded, baked, collet extruded, second generation, and 2G snacks. Wenger manufactures both single screw and twin screw extruders to help match your product and budget requirements.
Breakfast Cereal Systems
Extrusion cooking of ready-to-eat breakfast cereals offers numerous processing advantages over conventional processing methods. Among them, faster processing times, lower processing costs, less square footage required, shorter response time, and perhaps most important--greater flexibility in both processing and recipes to produce your desired finished product.
Added flexibility is made possible by the ability to quickly and easily change the extruder and/or processing steps for countless variations of ready-to-eat breakfast cereals. Merely changing the processing conditions and/or extruder die will yield an abundance of shapes and textures of direct expanded products, while adding components to the processing system allows similarly limitless opportunities with flaked products. Add the ability to coat the product with various flavors, dry and/or liquid additives, and the number of possibilities becomes limited only by the imagination.
All of this can be accomplished via continuous method PLC on-line control systems or by using simple batch methods. The extrusion cooking process allows a wider range of raw material specifications to assist in formulation of products of higher nutritional value than can be produced with conventional processing.
