Tnuva Dairy case study


Reliability and low cost of ownership are key factors in the success of two Linx 7900 CIJ (continuous ink jet) printers incorporating head traversing units which are printing 40,000 yogurt pots every hour at leading Israeli dairy company Tnuva Eilon Tavor.

The recently-installed printers are the latest in over 100 Linx machines that are in operation at Tnuva sites across Israel as part of a long-standing 14 year partnership between the company and Linx’s Israeli distributor International Process Equipment Ltd (IPE).

The 7900 models are working in conjunction with an Erca Form Fill Seal machine providing two lines of code – best before date and printing time – onto the printed paper lids.

Advanced QuickSwitch® software allows fast, time-saving changeovers between products or messages, with simple automated set-up, and the printer’s SureFill® system ensures mistake-proof refills

In addition, Linx PrintSync® enables automatic print format selection, using the line speed to provide the best possible print quality.

The Linx 7900 has been designed to deliver the lowest possible running costs, featuring dynamically adjusted service intervals that mean customers only pay for vital maintenance. It is able to run for up to 9,000 hours or 18 months between services.

The printer incorporates Linx’s successful FullFlush® automatic printhead cleaning system, while routine maintenance is minimal and, in contrast to other printers on the market, there are no expensive ink system assemblies to replace at every service. Similarly, there is no need to change the ink tank between services, another hidden cost with other ink jet printers.

The Linx printers were installed as part of Tnuva’s continuous improvement programme to renew existing coders, and selected after a comparison with an alternative ink jet model.
