High Performance Sorters for Pet Food and Rendering
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.
