A specialized Iso-Flo vibratory conveyor designed specifically for integration with a metal detector inspects bulk foods on processing and packaging distribution lines. Compared to traditional plastic or fabric belt conveyor systems integrated with metal detectors, Key’s vibratory solutions reduce maintenance and minimize product spillage while dramatically improving sanitation to maximize food safety.
This vibratory conveyor combines three conveyor bed sections—a stainless steel infeed, a non-metallic section that passes through the metal detector’s aperture, and a final stainless steel section with a reject device. Key designs each system to accommodate the customer’s preferred metal detector and aperture size. The infeed section can incorporate a screen capability to scalp or remove fines, small particles or water, if needed.
The stainless-steel conveyor beds feature a standard rotary polish within the product contact zone or one of several optional finishes to satisfy the needs of each customer. Standard oil-free drives, elastomer isolators, scalloped flat bars, patented stainless steel ground arms and minimal laminations maximize equipment hygiene and help meet rising sanitary standards and regulatory requirements. Unlike plastic or fabric belt conveyors with hidden surfaces that can trap bacteria, Key’s vibratory solutions present sanitary bed surfaces that are easy to clean. With no belting material, drive or discharge pulleys, and no bearings, drive belts or sprockets, Key’s robust vibratory systems minimize maintenance, maximize uptime and reduce the total cost of ownership.
Iso-Flo conveyors use independent, frame-mounted drives and spring arm assemblies that distribute energy equally to all parts of the conveyor bed in a controlled natural-frequency operation. The vibratory motion is contained, creating no noise or interference that could trigger the metal detector to a false reject.
