The recently installed line at Gambastar, based in Burgos, Northern Spain, comprises a 16-head Ishida CCW-RVE waterproof multihead weigher, QX-1100 automatic twin lane tray sealer and DACS-G checkweigher, which is weighing and packing fresh langoustines into a number of different-sized trays.

By replacing its previous linear weigher with the Ishida multihead, Gambastar has been able to increase line speeds from around 35 to 70 packs per minute. Equally important, the Ishida solution is delivering excellent accuracy – to within 2% of target weight on a typical 520g tray.

A particular benefit of the QX-1100 tray sealer is the single tool that is required for the three different tray sizes from 200g to 1kg. This means that changeovers between packs can take place within a matter of minutes with the corresponding settings quickly called up on the intuitive and easy to use remote control unit.

Product is fed to the weigher by a vibratory conveyor. From the dispersion table at the top of the CCW-RVE, the langoustines are transferred to the pool and weigh hoppers. It then takes a fraction of a second for the microprocessor to calculate the best combination of weigh hoppers to reach the target weight.

The selected product is transferred to a specially designed distribution system underneath the weigher. Trays are fed from a tray denester to beneath the weigher where dipping funnels ensure the complete and accurate placement of the langoustines. The trays are then fed into the QX-1100 tray sealer before receiving a final confirmatory weight check on the DACS-G checkweigher.
