Food metal detectors OR Micro Scan Metal Detector are primarily used in food and pharmaceutical industries to detect metal contamination in packets or products. With the highest accuracy and reliability, a food metal detector has the ability to detect all types of metals (ferrous, non-ferrous, or stainless steel). It plays a prominent role in ensuring product safety, equipment protection and regulatory compliance in the food industry. It also take care the reputation of a firm.
The working of metal detectors is simple. The appliance consists of a balanced, three-coil system, wound on a non-metallic frame. The centre coil is attached to a high-frequency transmitter, and the other coils serve as receivers. When anything metallic passes through the coils of a metal detector, the high frequency field is disturbed, thereby enabling easy detection of metal particles. Many of the sophisticated types of food metal detectors come attached with automatic reject mechanism, to reject products on immediate detection of metal contamination.
Depending on the specific purpose, different types of metal detectors are available for checking metallic contamination in the food industry. For examining small and unpacked goods such as vegetables, snack items, frozen foods, sea foods and poultry, conveyor type metal detectors are most suitable. Metal detectors with advanced microprocessor-based technology are highly advantageous for checking coarse-grained food stuffs such as popcorn, cornflakes and soup noodles.
A properly designed, installed and well-maintained unit, combined with an effective metal contamination control program, can best serve the purpose.
Metal Detectors are mostly used for USDA / HACCP / USFDA Certifications in India and Abroad.
