What Is a Metal Free Zone?

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.

Metal-Free Zone Specifications

Our metal-free zone specifications include:

  • Engineered plastic metal free mid-section to install a metal detector
  • The size of the zone is determined by the metal detection unit being integrated
  • Metal detector must be specified and acquired separately
  • Reference the conveyor specification sheet for additional details and specifications

What to Consider When Choosing a  Metal Free Zone Conveyor

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.

Sanitation

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.

Aperture Size

The aperture size must match the product specifications to scan the products correctly for metal detection. Aperture sizes tend to be 8 inches high by 14 inches wide, but customizations are available depending on business needs.

Reject Mechanisms

When the system detects metal or a foreign object, there needs to be a reject mechanism to remove the product from the line before further contamination can occur.

Multiple types of reject mechanisms are available, including push-on-detect, air blast, and diverter arms to remove questionable products from the line.
