Where to Install Magnetic Separators in Pet Food Processing

The complexity of processing, from ingredient handling to packaging, introduces multiple stages where foreign metal fragments can enter the production line. Although many processors understand the importance of magnetic separators in enhancing food safety, uncertainty often arises about the most effective equipment placement for optimal product security and machinery protection.

Effective Placement of Magnetic Separators

Strategically placed magnetic separators is critical for ensuring pet food safety and quality. There are a few locations where installing magnets is most beneficial:

1. Product intakes: Magnetic separators at the product intake stage —for both dry and wet ingredients applications— are essential for removing metal fragments, such as magnetic stones and work-hardened stainless steel, safeguarding machinery, and ensuring incoming materials meet quality standards. This is an important magnet to ensure that the product coming into your process meets your requirements.

2. Post-first stage mixing/wet ingredients processing: After the initial mixing phase, magnetic separators help extract contaminants introduced during processing. This stage reduces the strain on final-stage magnets, especially in cases with high contamination levels.

3. Wet line before canning/packing: In wet pet food production, magnetic separators play a vital role in the canning stage. Proper consideration of flow rate, particle size, and viscosity ensures effective contaminant removal, protecting expensive equipment like twin-screw pumps while safeguarding the final product before packing and metal detection.

4. Dry ingredients processing: Magnet placement during dry ingredient processing depends on factors like flow rate and protection level. Installing separators before extrusion prevents contaminants from being embedded in kibble, streamlining quality control measures and reducing potential hits on final-stage magnets.

5. Dry line before bagging: The final magnet before bagging serves as the last defense against contaminants before products reach consumers. Certified and traceable magnets provide reliable quality assurance and help demonstrate effective preventive measures.

Choosing a magnetic separator for these applications will depend on the flow rate, density, speed, and more.
