Innovative Leak Detection Technology Benefits MAP Quality Control

03 Apr 2020


Ishida AirScan uses laser technology to detect leaks of carbon dioxide (CO2), which is used in many MAP applications. The high-performance system checks each individual tray in less than 20 milliseconds for traces of escaping CO2.

The Ishida AirScan inline leak detection system is worth its weight in gold to us!

The Ishida Airscan can reliably find holes with a diameter as small as 0.25 mm, at breath-taking speeds of up to 180 packs per minute. Users will improve their product quality without any adverse impact on products, as the inspection process does not exert any pressure - unlike conventional inline seal testers - and is therefore completely non-destructive. The inline system can be integrated into existing packing lines in a few minutes, without requiring any modifications to existing conveyors.

The Ishida AirScan at M-Back has been placed at the end of the packing line, between other control systems and a labeller. Since its installation, quality assurance has reached new levels. About 3% of packs are identified as having a leak. These are eliminated using an air reject mechanism and transported to a collection chamber for subsequent repacking. 'We definitely find even smaller holes than 0.4 mm,' Marcel Schwebler reports. 'By way of illustration, if you immerse the packs that have been found to be faulty in a water bath, you won’t see any gas coming out. In a laboratory, however, we can detect changes in the composition of the gas mixture'.

There’s no alternative to the AirScan system when it comes to speed.

Ishida AirScan

This revolutionary leak detection system makes a real and immediate difference to the seal integrity of your tray packs.

In two-shift mode, the Ishida AirScan checks 3,500 packs of “Ofen Schnecke” per hour, which equates to a belt speed of 30 metres per minute. 'There’s no alternative to the AirScan system when it comes to speed,' says Marcel Schwebler. He also highlights the system’s userfriendliness and availability, pointing out that it is very easy and safe to operate and requires only minimum maintenance.

No changes to settings are needed for product changeovers; only the height-adjustable control arm with the sensor head needs to be adjusted to the different pack heights. Dry cleaning before and after each production batch is completed within ten minutes.
