Finally, keeping equipment clean and well maintained helps it run smoothly with minimal interruptions. Clean equipment produces pet food and treats that meet a processor’s high standards more consistently and efficiently. And pet food processors can extend the life of their extruders by implementing a maintenance program.

The key to equipment that will last is choosing the right equipment in the first place. “Depending upon the type of extruder, different functions can be performed,” says Galen Rokey, process technology director, Wenger Manufacturing, Sabetha, Kansas. “These include expansion, gelatinization, homogenization, dehydration, mixing, pasteurization, protein denaturation, shearing, texture alteration and product shaping.” Before purchasing an extruder, pet food processors should know the finished product and volume they require; the shapes, sizes, desired textures and the raw materials they’ll be working with from the outset.

“Processors need to let equipment manufacturers know what kind of finished product they want so the manufacturers can design the extruder for their application,” Riaz says. “There is low shear, medium shear and high shear, all designed for different products, and similarly, the twin-screw handles different products.”

Pet food processors must establish operational requirements up front with their equipment suppliers about their goals so the extruder can get the job done in an optimal way. These conversations, as well as testing the raw materials on suppliers’ equipment, will help pet food processors get a clear picture of what extrusion system and components will work best for their products. “This will determine overall screw length, screw elements for best mixing and cooking, and functionality of control systems to proportion ingredients and liquids while fine tuning speed and temperature,” says Dave Carney, area sales manager, Buhler, Cary, North Carolina.

Whether or not the product will be raw or cooked is also an important distinction processors need to make to extruder suppliers, as extruders can do both. “I need to understand if a customer wants to portion the extruded product as a raw product or if they want to portion the cooked product,” says Jay Wenther, Ph.D., director of meat technology, Handtmann Inc., Lake Forest, Illinois. “This assists in determining what extrusion may work for them and be the most economical for their business.”

While most pet food is made in single-screw extruders, that may not be the best hardware to process high protein treats and food that is growing in popularity. “Some products can’t be made on a single because a twin-screw extruder can handle very viscous, oily, sticky materials,” Riaz says. “We use a twin screw when you need high protein, high fat or high moisture.”

Clextral gives pet food processors the ability to test their products on Clextral extruders at one of two research centers, one in the US and another in France. At these centers, Clextral’s customers can develop and test new formulations and take advantage of the company’s mechanical, electrical and automation training services. First and foremost, though, pet food processors can have the opportunity to test all the different components Clextral offers on its extruders to find the appropriate hardware for their products. “Clextral provides many options including specific die designs for innovative shapes and special knives that are able to cut highly viscoelastic products in a very consistent process,” says Alain Brisset, Clextral SAS, Firminy, France.

Beyond the actual machine, it’s important that the production line matches the throughput a pet food processor expects. Over-sizing the line is not always the best strategy for expansion and can potentially hinder the line from running at its best. “Instead of buying a larger capacity and only running it half the time, buy a line for five tons and run five tons,” Riaz says. “If you grow, buy another line. To process properly, you have to have the right capacity on the entire system both upstream and downstream from the extruder.”

“Pet food processors need to ultimately take a close look at what they are currently producing and what products they have in the research and development pipeline,” Wenther says. Accommodating these product expansions is easier with equipment that is flexible enough to adapt to a growing business. An extruder that lasts is an extruder that keeps up with a changing business.

Flexible equipment is designed for quick changeovers. While one extruder may be capable of producing many different products, many of the components on the extruder may need changing to accommodate the next product’s needs. “It may take several extrusion forming dies or a different extrusion configuration,” Wenther says. Screws, dies and knives must all accommodate new raw materials and create a new shape, size and texture.

The screw, which mixes and sometimes cooks the dough, lives inside the extruder barrel. The screw configuration, however, needs to change to handle a new formulation and create a different texture. Operators require easy access to the screw to remove it and change its configuration. To do that, Clextral’s twin screw extruders have an automatic hydraulic barrel opening to provide screw access at the push of a button. “In addition, easy access to the screw-caps and screw pattern enables quick reconfiguration during changeover, and offers convenient, preventive maintenance,” Brisset says.

Dies and knives, which control the size and shape of individual pieces, also need to be quickly and easily changed with each product. “Dies have a quick-clamp design for easy removal and replacement, and cutters offer complete adjustability,” Brisset says of Clextral’s extruders.

Another aspect in the extruder that needs to be flexible is the pumping system. A pumping system needs to be able to deliver accurate portions and handle a diverse array of viscosities. “A piece of equipment designed to be versatile, like a Vemag extruder, will have the ability to swap pumping elements or front-end attachments to allow for new products,” Reiser’s McIsaac says.

The Vemag extruder, offered by Reiser, features a powerful positive displacement double-screw pump that provides high portioning accuracy while transporting product gently without degradation. There are a number of double-screw configurations offered which allows pet food processors to produce a variety of products with one machine. “A Vemag using a double-screw to produce a high volume of dense product can also be used to produce a highly accurate stream of liquid product with a simple change of the double-screw pumping element,” McIsaac explains.

A thorough and routine sanitation and maintenance program can keep an extruder running efficiently for many years. Conveniently, many of the same characteristics that make extruders flexible also make them easy to clean and maintain.

These design elements make clean-up and changeovers go more quickly, saving time and boosting efficiency. Clextral designed its extruders for hygienic processing including open profiles for full machine access and continuous hygienically welded machine construction, eliminating bolted joints. The company’s Evolum+ line of equipment is constructed with full stainless steel or stainless/painted steel construction. It also features open design for easy access. In Clextral’s Preconditioner+, the additional conveying bottom screw allows operators to completely empty the tank quickly, which is useful in speedy cleaning and changeovers.

Understanding a current product line as well as the pet food products of the future will help processors ensure they get the right extrusion system that will go the distance. Purchasing a flexible system that is optimized for their product line will help equipment operate at its best at all times. And staying on schedule with a sanitation and maintenance program will keep everything moving smoothly and get the most life out of an extruder.
