Flawless product inspection of pet food

Pet food manufacturers use advanced product inspection systems to maximise pet food safety, while enhancing customer loyalty. Providing quality pet food is an important key in promoting good animal health. Using checkweighers and X-ray inspection solutions during pet food manufacturing and packaging ensures consumer value, while protecting pet food brand integrity.

Our pets are family members that deserve world-class product inspection of their pet food

In many societies our pets have become full-fledged family members. As such we want to see our pets thrive and remain healthy just like any other family member. In the U.S. alone, dog and cat owners spent $26 billion on just dog and cat food in 2017, and the rate of this spending is growing at about 6% per year.¹ The 2017 worldwide pet food sales targeted at just dogs and cats was approximately $59 billion.

A recent study of dog and cat owners found that over 70% of pet owners agreed with the statement “High-quality pet food is effective for preventive health care.²”

Other studies indicate that pet owners are more interested in pet food products having “clean labels.” Clean labels in this context means that the pet food contained within the package is exactly what the label states, in terms of weight and product purity. Dynamic product inspection techniques are employed to ensure that the pet food manufacturer’s product label matches the contents of the package.

Product inspection systems used to ensure the product label matches the contents:

  • To maintain customer loyalty, pet food manufacturers use product inspection during the production and packaging processes that ensure their pet food products have the correct fill weight and are free of foreign body contaminates.
  • Like human food, the Federal Food, Drug and Cosmetic Act (FDA 21 CFR 113) requires that pet food be “safe to eat, produced under sanitary conditions, contain no harmful substances and be truthfully labeled.” Effective, in-motion product inspection is a key factor in ensuring safety.
  • Worldwide pet food packaging and safety requirements exist, such as the EU regulation 767/2009 covering basic pet food labeling requirements. The European Pet Food Industry Federation (FEDIAF) has also developed guidelines (FEDIAF, 2015-A) to ensure a supply of safe and nutritious pet food.

Wipotec is a well-known provider of checkweighing and X-ray inspection systems used in the inspection of pet food. Pet food companies around the world have come to rely on our checkweighers and X-ray scanners as proven product inspection methods that enhance their customer’s trust in their pet food products.

Pet food quality assurance is important to ensure both consumer value and pet safety

Value – A checkweigher story

  • Nothing is worse than paying for something and receiving less of what you bought. Wipotec checkweighers prevent that problem. A checkweigher placed after the pet food package filling machine performs high-speed, in-motion weight checks of the utmost precision without any slowing of the production line.
  • Our HC-A high-speed checkweighers are ideal for checking the individual weights of premium cat food cans exiting the filler at a rate of 640 pieces/min.
  • The HC-M-WD-SL and EC-E-SL checkweighers handle weighing of heavy loads typically found in applications involving checking the weight of large bags of dry dog food and other animal feeds.
  • There are multiple checkweigher machines to handle variations of pet food weighing based on the customers unique product packaging and manufacturing requirements.

Pet Safety – An X-ray story

  • X-ray product inspection prevents pet food shipments containing foreign bodies from reaching the market. Foreign body detection (FBD) includes setting the X-ray scanner up to find bits of metal, plastic, stones, and others in the bulk pet food and rejecting it before reaching the pet food can or bag fillers.
  • X-ray product inspection is also used after the pet food fillers to perform fill-level and completeness checks.
  • Various Wipotec X-ray inspection systems are available for pet food product inspection. The type of X-ray scanner deployed depends on several application parameters including where in the pet food manufacturing process the scanner is needed, and the type of product inspection tasks the scanner needs to perform.
  • Pre-bagger/package filler – usually the SC-B X-ray scanner  is used here for X-ray foreign body inspection of the bulk pet food.
  • Post-bagger/package filler – a number of options available, such as the SC-E and SC line of X-ray scanners. The choice largely depends on the unique application parameters related to package type, speed, product orientation, and the required product inspection tasks. An SC-V optical inspection scanner is an option for those applications requiring both an X-ray scanning set of tasks, as well as needing to perform visual checks on the final pet food package label.

Reliable marking with TQS

Improve your end-of-line control systems to ensure the highest quality standards in marking and labeling! With TQS, our Traceable Quality System, one single unit combines all the modules you need to mark and check high-quality pet food. A best-before date, for example, must be clearly displayed on the packaging of each individual item to protect our dearest four-legged friends from unhealthy surprises. In addition, dynamic batch coding enables accurate traceability throughout the entire lifespan of a product. In the event of a recall, this makes the process much smoother.

Customized for pet food

If required, we combine marking and weight control with additional modules for optical inspection or foreign body detection. This ensures that you keep the food free of any contamination. We also have comprehensive solutions in our range, like our TQS-HC-A-XL, which even take care of complete labeling functions for you. With this system, you will easily handle even the voluminous packs of dry compounds or heaviest shipping cartons. Whether it is cans, pouches or cartons, TQS adapts completely to your specifications. You always receive a customized solution.

This demonstrates the flexibility of the modularity on which our systems are based. We always focus on your requirements and pursue a holistic approach in which every unit is fully integrated. That's why a single touchscreen is all you need to control the entire system. Consequently, you only have one contact person who can deal with any issues quickly and competently. This is the future. The more components we combine, the easier it is for you to use.

The potential of 2D technology

The same principle applies to the marking of your products. A rapidly growing number of pet food manufacturers are now labeling their products with smart 2D codes. These small squares have the great advantage of providing a wide range of information in a very small space. Thanks to integrated web access, the functionality is not limited to showing expiry dates or price but can also tailor information directly to a specific target group.

By scanning with their smartphone, customers receive information on the nutritional value of the food, for example, or can sign up for a contest. Your retailers will be able to authenticate your products by the code, for example - and that's just a fraction of what 2D codes are capable of in retail. If you would like to find out more about where product labeling is heading and how you as a manufacturer can benefit from these developments, please get in touch with our experts.
