United Biscuits reduces product wastage
14 March 2012 – United Biscuits has installed 62 throat metal detectors on all crisp packaging lines at one production site. This has resulted in improved processing efficiency and a significant reduction in product wastage.
Previously, the packing lines were fitted with conventional end of line metal detectors which were inspecting sealed multi-packs of crisps each containing up to nine individual bags of the snack product at the end of the packaging process – however the main drawback when inspecting sealed multi-packs, was the wastage potential if a foreign metal object was detected in one individual bag, then the entire multi-pack would be rejected.
In contrast MET30+ Universal throat metal detectors, from Lock Inspection Systems, were retrofitted to nine crisp packing lines within the confined space between the outlet of the multi head weigher and the inlet to the VFFS bag maker in order that crisps were inspected during the free-fall prior to entering the bag.
