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.

寵物食品制造中的“產(chǎn)品效應(yīng)”是什么？

“產(chǎn)品效應(yīng)”是指產(chǎn)品的導(dǎo)電性能會影響食品金屬探測器產(chǎn)生的磁場。這通常存在于高鹽、高濕度的產(chǎn)品環(huán)境中。例如，濕貓糧將顯示出顯著更多的產(chǎn)品效果，由于其高水分和鹽含量。這會對金屬檢測機區(qū)分實際有色金屬污染物和典型產(chǎn)品屬性組合給出的假信號的能力產(chǎn)生負面影響。在這些情況下，工業(yè)X射線檢測設(shè)備將產(chǎn)生更好的結(jié)果，因為產(chǎn)品效應(yīng)不是一個因素。

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

寵物食品生產(chǎn)線上使用檢測設(shè)備的最佳位置在哪里？

在寵物食品生產(chǎn)過程中，食品安全檢測（金屬探測器、X射線檢測）和自動檢重技術(shù)有幾個方面受益。以下是一些示例：

- 進料。大型寵物食品生產(chǎn)商可能會要求其供應(yīng)商滿足特定的HACCP目標并提供檢驗證明。即使有了這些方法，有些人也會檢查進料。典型的來料檢驗包括直通式和散裝式金屬檢測機。

- 混合/渲染后。工業(yè)攪拌機或混合器等加工設(shè)備會隨著時間的推移而老化，并可能將小顆粒或金屬屑引入正在加工的產(chǎn)品中。重要的是將檢測設(shè)備放置在該工藝設(shè)備之后，以便在生產(chǎn)中盡早捕獲任何污染物，這樣就不會影響最終產(chǎn)品質(zhì)量，也不會損壞下游的設(shè)備。檢測設(shè)備類型將取決于產(chǎn)品類型及其配方是否產(chǎn)生“產(chǎn)品效應(yīng)”。濕或濕的寵物食品更適合 X 射線設(shè)備，而金屬探測器在干燥或粗磨型寵物食品中表現(xiàn)良好。

- 灌裝/包裝后。推薦的檢測設(shè)備類型取決于為本產(chǎn)品選擇的包裝材料或材料組合。鋁箔托盤、金屬罐、鋁箔袋或金屬化堅固結(jié)構(gòu)等金屬部件更適合 X 射線檢測。沒有金屬部件的柔性材料、紙板折疊紙箱、袋子或小袋與金屬探測器或 X 射線檢測系統(tǒng)配合使用效果非常好。在這個階段，自動檢重秤經(jīng)常與金屬檢測機或X射線檢測系統(tǒng)結(jié)合使用，以確保產(chǎn)品重量與產(chǎn)品標簽上打印的信息相匹配。

- 裝箱后。后箱包裝是另一個很好的檢查點

What is the best inspection technology to find broken or missing pieces in snack bags?

In the case of snack bars and other similar snack products, food X-ray inspection (https://www.thermofisher.com/us/en/home/industrial/food-beverage/food-weighing-inspection/x-ray-detection-inspection-systems.html) can be used for spotting missing or broken pieces.

以小食店及其他類似小食產(chǎn)品為例，食物X光檢驗（https://www.thermofisher.com/us/en/home/industrial/food-beverage/food-weighing-inspection/x-ray-detection-inspection-systems.html)可用于發(fā)現(xiàn)丟失或破碎的碎片。

What is the best inspection method for sauces and dressings that contain dairy products? .

Pipeline X-ray inspection is the best methodology for dairy inspection, as formulations can be complex and frequently modified. This can negatively affect metal detector performance due to varying product effect.

含有奶類制品的醬料和敷料，最好的檢查方法是什么？。

管道X射線檢測是乳制品檢測的最佳方法，因為配方可能非常復(fù)雜且經(jīng)常修改。由于不同的產(chǎn)品效果，這可能會對金屬探測器的性能產(chǎn)生負面影響。
