Food grade metal detectors come in many different types, from conveyors to pipelines to gravity feed. Choosing the right detector for your business can be critical and may depend on various factors, including the type of product you’re manufacturing and the type of packaging you use. You should consider your options carefully before making a choice to ensure that you are best able to comply with the government’s ever-tightening food safety guidelines.
Food safety is not something to be taken lightly, as even one contaminated product reaching store shelves can have a disastrous effect on your company both from a financial and PR perspective. This is why food safety guidelines have been put in place and why the use of metal detection system has become the standard in the industry.
There are two basic types of detection systems: metal detectors and x-ray systems. Food grade metal detectors are used to identify the presence of all types of metals within food products. An x-ray system can be employed to detect other types of contaminants, including glass, stone and plastics. Many manufacturers opt to employ a combination of both for maximum safety.
In terms of metal detectors, the different types are used to inspect different types of products. For most packaged products, conveyer systems are ideal. In these instances, the detector uses a series of coils, which produce fields to identify the presence of a contaminant within a product package and automatically reject the package once contamination is confirmed. If the packaging is metalized, then a detector that employs magnets can be utilized instead.
For non-packaged products, a company may require the use of other types of food grade metal detectors. Vertical detectors can scan loose (i.e. powdered) products as they are pumped into bags while pipeline systems detect contaminants in liquids and soft, dense materials like sausages and cheeses. The contaminated products are then channeled into isolation bins to remove them from the production line.
No matter which type of detector you use, it is crucial that you perform regular tests of your equipment to ensure that it is working properly. Tests are performed by inserting a specially designed test piece into the production line, either within a sample pack of the product or directly in the flow of loose, unpackaged product. If the detector is working properly, it should identify and reject the test sample.
Ensuring the accuracy of your food grade metal detectors is necessary for adhering to food safety guidelines. In order to do so, you should employ only the best quality test pieces such as those designed and created by Regal Packaging Services, Inc. We provide each customer with test pieces to meet the individual specification of their system and certify each individual piece to guarantee quality and durability.
Safety is paramount in the food industry today and that means employing the best food grade metal detectors and testing them regularly. With high quality test pieces from Regal Packaging Services you can be sure that your metal detectors are always functioning at their best and that your business is protected. Peace of mind like that is something you just can’t put a value on.
