Processing benchmark in

Processing benchmark in product safety at the same time as minimizing false rejects and food waste. By using new, bestin-class laser technology combined with TOMRA’s unique BSI+ (biometric signature identification) scanner, the unseen becomes visible, making foreign materials a problem of the past. These technologies are also highly effective at sorting-out discoloration, black spots, embedded plastic, doubles, thin coating, and voids. Sorters for pet food and rendering Producing food for pets is strictly regulated by local and global legislation which is designed to ensure product quality and food safety. Complying with these regulations requires the use of safe ingredients and additives, hygienic processing practices, and HACCP (hazards analysis and critical control points) management - but even so, there is still the risk of foreign materials entering the manufacturing facility in raw materials. This is why TOMRA works closely not only with pet food manufacturers, but also with their suppliers in the rendering industry. Important protein sources in both wet and dry pet food are animal-derived ingredients. However, entering the rendering facilities these ingredients often contain various foreign bodies which come from the abattoirs, such as rubber parts, foils, wood, glass, and metals. This is hard to avoid with an automated production line, but also mostly hard to detect with conventional methods such as metal detection and/or X-ray. The TOMRA 5C solves this, preventing foreign materials from reaching the pet food manufacturer. This sorter often acts as the final control on the meal line: placed after the final screen, it not only detects and rejects even the smallest particle of foreign material but also sources out all the good product coming from the screen, feeding this into the good stream again. These capabilities, plus the ability to regulate the ash content to enhance the final quality, make the TOMRA 5C essential for every meal stream. In dry pet food, foreign material isn’t the only threat - there’s also the problem of cross-contamination. And as a solution, the TOMRA Nimbus is unbeatable. This machine’s various sensors protect against foreign materials, loose and embedded, and cross-contamination - and with TOMRA’s new pet food software, the change over from one recipe to the next is like a snap of the fingers. This eliminates traditional ways of trying to avoid cross-contamination which are both time-consuming and product-consuming. TOMRA’s unique BSI+ technology checks the inside of materials, ensuring that different types of kibble don’t get mixed even if they are near-identical in outward appearance, and by using the new petfood software, the operator always has the best view on what to produce next. For producing best-in-class pet treats and snacks, foreign materials must be prevented from ending up in the final package, and products should have the same size, form and color. For this the TOMRA 5B is the perfect solution, ensuring that only the right products get into the package. In wet pet food, the TOMRA 5B is ideal for the inbound set-up, where incoming frozen blocks pass through either a breaker or a grinder before entering the mixer. Placed between the breaker/ grinder and mixer, the TOMRA 5B effectively detects and sorts various foreign materials including stones, hard and soft plastics, metal, wood, glass, rubber and bones. In addition to protecting final products from unwanted materials, the TOMRA 5B also logs every batch, so it is possible to assess what’s coming from suppliers accurately. An investment that pays back well When processors and renderers first adopt TOMRA’s sorting solutions, they are pleased to find that the once-steady trickle of customer complaints dries up. One good example of this is JG Pears, a leading processor of animal by-products and food waste in the UK, producing a range of meals and fat for the pet food industry. The company’s Site Manager, Craig Harrison, said: “Non-conformances with our customers have reduced dramatically, and we see very, very little waste or foreign bodies in our material. Our current customers have seen the difference in the finished product and there’s lots of interest from additional customers enquiring about buying our material.” In addition to keeping customers happy, then, TOMRA’s sorting machines are also a key which can unlock new business. One of many business leaders who will affirm this is Andy Kettle, Managing Director of GA Pet Food Partners, Europe’s leading manufacturer of private label premium dry pet food. He commented: “TOMRA’s technology has helped us break open new markets which previously would not have been available to us. For me, it has been one of the best investments made by the business in the last three to four years.” fmt 26 food Marketing & Technology • April 2022

Processing Measurement Technology: Exploiting the Potential of Industry 4.0 It was 10 years ago that the research advisory committee to the German government used the term “Industry 4.0” for the first time in public at the Hannover Trade Fair. Numerous solution approaches for the process industry have been developed since then. With its Industry 4.0 program, Endress+Hauser is working together as a technology pioneer with customers and partners to unleash this potential in the area of process instrumentation. What is already possible today in the food and beverage industry and where is this sector headed? Attributing the potential of a fourth industrial revolution to process informatics and the concept of cyberphysical systems in advance was a bold step. If we analyze the history of the previous “revolutions”, what really stands out with the utilization of steam power for mechanization is that the efficiency of the technology determines its success. From the time it was invented (1698, steam pump, T. Savery), steam power required roughly 160 years to fully establish itself in industry and unlock its potential. Let’s take a closer look at the state of digitalization 10 years after the rise of the term Industry 4.0. 97 percent of the data from the field remains unused Depending on the size and the industry, a modern production operation has between 50 and 2,000 measuring points for measuring, controlling and automating its production processes and making them reliable. Apart from the actual measurement values, today these instruments can supply additional data and information, although analyses by Endress+Hauser show that up to 97 percent is still unused. This is where Endress+Hauser’s Industry 4.0 program comes into play, combining harmonized intelligent process sensors, cloud apps, interfaces and connectivity components and translating them into practical solutions. Especially relevant for the food and beverage industry are solutions for the plant overview, plant monitoring and mobile asset management. Smart sensors are the key to Industry 4.0 The Endress+Hauser Industry 4.0 program makes this data from the smart field instruments available. This begs the question, what makes a field instrument a “smart sensor 4.0”? Communication concepts play an important role here. Integrated web servers already enable direct operation and data exchange with a laptop. The OPC UA communication standard permits the manufacturerindependent integration of measurement and status information in downstream business processes. The product portfolio of instruments with Ethernet-based field buses is steadily growing as well. The cloud-based Micropilot FWR30 level measurement instrument even makes wireless level measurements for mobile tanks possible. Sensors with internal testing functions Other criteria that make a sensor a smart sensor are internal instrument Smart sensors are the key to digitalization: flow sensors from the Proline 300/500 family feature an integrated web server, WiFi and a self-diagnostics system.
