Optimizing PU control at tunnel pasteurizers

To compensate for fluctuations caused by line-entailed malfunctions or halts, we can provide a fast, flexible PU control designed to ensure consistently high product quality. A PU control of the latest generation can be retrofitted to all Sander-Hansen tunnel pasteurizers that are still equipped with a PUC1 or also to models from other manufacturers.
The PU control upgrade for both Sander-Hansen machines and other manufacturers’ models permits exceptionally accurate and dynamic control of the PUs, with high-precision spraying and a continuously operating flat-bed conveyor. The PU control ensures that 95 per cent of the containers are pasteurized with the set point value, or exceed it by only a maximum of 50 per cent. The remaining five per cent of the containers will likewise lie above the set point value, at not more than twice the preset level, thus precluding the possibility of under pasteurization.
