What is "product effect" in pet food manufacturing?

“Product effect” occurs when a product has a conductive property which affects the magnetic field generated by the food metal detector. This is typically found in high salt, high moisture product environments. For example, wet cat food will show significantly more product effect due to its high moisture and salt content. This negatively impacts the metal detector's ability to distinguish between actual non-ferrous metal contaminants and the false signal given by the combination of typical product attributes. In these situations, industrial X-ray inspection equipment will produce significantly better results since product effect is not a factor.

宠物食品制造中的“产品效应”是什么？

“产品效应”是指产品的导电性能会影响食品金属探测器产生的磁场。这通常存在于高盐、高湿度的产品环境中。例如，湿猫粮将显示出显着更多的产品效果，由于其高水分和盐含量。这会对金属检测机区分实际有色金属污染物和典型产品属性组合给出的假信号的能力产生负面影响。在这些情况下，工业X射线检测设备将产生更好的结果，因为产品效应不是一个因素。

Where are the best places on the pet food production line to utilize inspection equipment?

There are several points in the pet food production process that benefit from food safety inspection (metal detectors, X-ray inspection) and checkweighing technology. Here are some examples:

- Incoming ingredients. Large pet food producers may require that their vendors meet specific HACCP objectives and provide proof of inspection. Even with those methodologies in place, some will also inspect incoming ingredients. Typical incoming inspection consists of drop through and bulk flow metal detectors.

- After mixing/rendering. Processing equipment such as an industrial blender or mixer will age over time and potentially introduce small particles or shavings of metal into the product being processed. It is important to position inspection equipment after this process equipment to catch any contaminants as early in production as possible, so it doesn't affect final product quality as well as damage equipment further downstream. The inspection equipment type will depend on the product type and whether its formulation creates a “product effect”. Wet or moist pet food products are more suited toward X-ray equipment, while metal detectors perform well with dry or kibble type pet food products.

- After filling/packing. The recommended inspection equipment type is dependent on the packaging material or combination of materials that have been selected for this product. Metal components such as aluminum foil trays, metal cans, aluminum foil bags or metalized firm structures are much more suited to X-ray inspection. Flexible materials without a metal component, paperboard folding cartons, bags or pouches work very well with either metal detectors or X-ray inspection systems. At this stage, checkweighers are frequently used in combination with a metal detector or X-ray inspection system to ensure product weight matches information printed on the product label.

- After case packing. After case packing is another good inspection poin

宠物食品生产线上使用检测设备的最佳位置在哪里？

在宠物食品生产过程中，食品安全检测（金属探测器、X射线检测）和自动检重技术有几个方面受益。以下是一些示例：

- 进料。大型宠物食品生产商可能会要求其供应商满足特定的HACCP目标并提供检验证明。即使有了这些方法，有些人也会检查进料。典型的来料检验包括直通式和散装式金属检测机。

- 混合/渲染后。工业搅拌机或混合器等加工设备会随着时间的推移而老化，并可能将小颗粒或金属屑引入正在加工的产品中。重要的是将检测设备放置在该工艺设备之后，以便在生产中尽早捕获任何污染物，这样就不会影响最终产品质量，也不会损坏下游的设备。检测设备类型将取决于产品类型及其配方是否产生“产品效应”。湿或湿的宠物食品更适合 X 射线设备，而金属探测器在干燥或粗磨型宠物食品中表现良好。

- 灌装/包装后。推荐的检测设备类型取决于为本产品选择的包装材料或材料组合。铝箔托盘、金属罐、铝箔袋或金属化坚固结构等金属部件更适合 X 射线检测。没有金属部件的柔性材料、纸板折叠纸箱、袋子或小袋与金属探测器或 X 射线检测系统配合使用效果非常好。在这个阶段，自动检重秤经常与金属检测机或X射线检测系统结合使用，以确保产品重量与产品标签上打印的信息相匹配。

- 装箱后。后箱包装是另一个很好的检查点
