Loma - IQ4 Metal Detector

• Detecting metallic contaminants in packaged food products such as ready meals, baked goods, and confectionery.
• Inspecting bulk dry goods like grains, powders, and snacks for metal foreign bodies.
• Ensuring product safety and quality in pharmaceutical production lines by identifying metal particles in tablets or capsules.
• Protecting downstream processing machinery from damage caused by metal contaminants in non-food applications.
• Quality control in industries handling plastics, textiles, or recycled materials to remove metallic impurities.

Typical throughput

Varies significantly based on product type and line speed; units of this class can typically handle hundreds to thousands of items per minute.

Power supply

Commonly operates on standard industrial single-phase or three-phase power, typically 230V or 400V AC.

Detection sensitivity

For this class of equipment, sensitivity is typically very high, capable of detecting ferrous, non-ferrous, and stainless steel contaminants down to sub-millimetre sizes.

Aperture size

The aperture width and height determine the maximum product size that can pass through; this unit's stated aperture is 250mm W x 145mm H.

Reject mechanism

Units of this type commonly feature various reject mechanisms such as stop-on-detect, air blast, or push-arm, with 'stop reject' indicating the line pauses upon detection.

Construction material

Typically constructed from stainless steel for hygiene and durability, suitable for washdown environments.

• What types of metal can this detector identify?

  Loma IQ4 metal detectors are designed to identify ferrous metals (e.g., iron), non-ferrous metals (e.g., aluminium, copper), and various grades of stainless steel.

• Is this unit suitable for wet or dry products?

• Can the sensitivity be adjusted for different products?

• What maintenance is typically required for a metal detector?

• What is a 'stop reject' mechanism?

Metal detectors for food processing remain reliable workhorses in quality control operations. Buyers typically value their durability and consistent contamination detection capability. When purchasing used units, inspecting calibration history and sensitivity settings proves essential. Industry sentiment favours machines with straightforward maintenance records and minimal downtime. Common strengths include robust construction, straightforward operation, and cost-effectiveness compared to new equipment. Prospective buyers should verify functional testing documentation and assess integration compatibility with existing production lines.
