The IQ4 conveyor systems offer the latest 7” color touchscreen with the engaging new user interface are designed to make light work of setting, running and maintaining the IQ4 range, minimalizing user errors.

The system takes advantage of nearly 50 years of LOMA's innovation and experience in conveyorized solutions for contaminant metal detection in the food industry and offers optimized mechanics to deliver performance improvements using variable-frequency detection (31 to 882 KHz).

LOMA’s conveyor systems comply with strict international standards such as IFS, BRC and FSMA; and can also be supplied with the highest level of compliance to meet strict Retail Codes of Practice (COP).


Conveyors with Automatic reject stations

The IQ4 Rectangular head is available with a conveyor using automatic reject stations. These systems are designed to maintain a high throughput, increase productivity and are typically good for fast applications and pack speeds. Multiple reject system types are available, and the correct choice entirely depends on the application.

Conveyor’s with automatic reject stations can be supplied with varying levels of compliance depending on the customer requirement. These are broken down into two levels of compliance; Retail and Full Retail which are made up of different features depending on the COP you comply with.

LOMA's reject types for different applications:

Air Blast – This can consist of either a single or dual nozzle system which is designed to be used with products that are wrapped and weigh up to 0.8kg
Pusher – The pusher is designed to be either side or overhead the conveyor for wrapped product in rigid packaging and is also available with heavy duty construction. If polybagged product is used a brush strip is needed under the pusher blade to reduce trapping.
Carriage Retract – Ideal for continuous loose product, separate products in parallel lanes across the belt, polybags and sachets.
Diverter / Plough – Typically used on more delicate or higher value products using a sweeping action to reject contaminant products.
Power Decliner – Situated at the end of the out the outfeed conveyor, products exit via the decliner onto another conveyor to then be rejected, this is mostly used with checkweighers.

7” Touchscreen with a new easy to use interface
Standard across all of the IQ4 range, the big 7” touchscreen is 33% larger than previous generation metal detectors and so offers easier usability.

Faster, Better Auto-Learn
With significant improvements in signal processing, the new Auto-Learn rapidly delivers excellent detection sensitivities out of the box and provides more line up-time than ever before.

Robust “Beyond” IP69K rating
An improved lip, screen, and new blue sealing arrangement, combined with ultra-harsh mechanics proven from the IQ3+ range, make this one of the toughest and factory friendly metal detectors on the market.
