Safety is a key concern for industries such as food packaging, making it crucial to use the right equipment to ensure that food inspection is completed to the highest standard. Dorner offers metal free zone conveyors for food inspection. To do this, we offer conveyors that can be integrated with a metal detector. This type of equipment can make certain that the food on the line is safe and free from metal and other foreign objects that may cause contamination. A metal detector and conveyor can help protect your products and customers.

Conveyors and metal free zones are used in industrial food inspection and food packaging to ensure that all food on the line is sanitary and safe from contamination. Metal free conveyors are used in the manufacturing and packaging industry for transfers in through and out of:

• metal detectors
• metal free zones
• rejection systems
• lockable reject bins
• networking interfaces for real-time performance information

A metal free zone is an area surrounding the industrial or sanitary conveyor where no metal is present. In order to prevent false alarms and detections, no fixed or moving metal is kept near the metal detector’s aperture to ensure optimum detection and prevent false results during the inspection process.

Conveyors are invaluable during the product inspection process because of the automation and accuracy they offer. When paired with a metal free zone, conveyors can initiate reject mechanisms as needed, creating a more streamlined inspection process. The automation of metal detection is necessary for high-quality food inspection that meets the standards needed and protects the integrity of food packaging options.

The Series is a low profile, high-performance fabric, and modular belt conveyor. It features a high-speed nose bar transfer option, a durable single piece frame design, universal T-slots, and a wide range of belting and guiding options. 

The Series is best used for small and medium part handling and is designed specifically to improve efficiency, reduce downtime, and increase accuracy during the metal detection process.

The Series are available as a belted, modular belt or precision move conveyor. Dorner’s online configurator engineers simple or complex conveyors to meet your needs in minutes, allowing you to customize for operations as needed quickly and effectively.

The Series is effective due to its fast speed, reliability, belt tracking, and other features that help make food inspection a quick and seamless process.

The AquaGard metal free zone conveyors are specially designed and manufactured for the food packaging industry and feature a rugged and durable design and additional sanitary features.

The AquaGard conveyors are designed for wipe down and low-pressure wash-down with non-caustic chemicals. The 304 Stainless Steel frame features an open design with minimal horizontal surfaces to ensure reliable metal detection. 

The AquaPruf conveyors by Dorner feature specific designs that are crucial for food packaging and inspection. AquaPruf sanitary conveyors are engineered to promote hygienic design while meeting the sanitary standards of the Baking Industry Sanitary Standards Committee (BISSC), 3A, USDA, and other FDA regulations. 

The AquaPruf series features fast and effective metal detection while adhering to key food safety standards. In addition, the AquaPruf features high-pressure sanitation and quick dismantling and assembly for effective cleaning

When deciding on a conveyor and metal free zone, there are a few different factors that need to be a consideration during the evaluation process. Your equipment needs to work quickly, spot contamination and offer multiple product disposal methods to add value to food packaging and inspection processes. Here are some of the key aspects of a conveyor and metal free zone that you should know to select the best option for your business.

Food inspection adheres to high standards and regulatory bodies, which is why sanitation features are vital. Having sanitation measures available in the conveyors makes it faster and easier to continually clean surfaces, monitor flagged products, and remove as needed to ensure that lines are running efficiently.

A diverter arm swings out across the width of the conveyor belt to remove flagged products from the line and dispose of them. It is best used for bulk products as it can remove a section of the product when the arm is activated, and therefore can remove more.
