The recipe for the perfect vacuum pump
Ingredients: No air, no oil, no water, no Service down-time
Few things beat a vacuum for keeping food fresh. And while the food industry already makes extensive use of vacuum pumps, other clean environments are now discovering their advantages. But choosing the most effective pump isn’t simply a matter of taste. So here’s some food for thought from Leybold.
Avoiding food contamination is a high priority for food producers. Yet traditional oil-sealed rotary vane pumps carry huge risks of lubricant oil product contamination. That’s why many producers are now choosing the risk-free option of the Leybold NOVADRY 100% oil-free vacuum pump.
Just look what you’ll be missing
With Leybold’s oil-free, air-cooled, dry screw NOVADRY vacuum pump, you’ll avoid lubricating oil & water-cooling circuit.
With its optimised rotor design and integrated silencer, you’ll even miss irritating noise that spoils the working environment.
All these benefits, combined with a design which complies with all basic hygienic principles, make the NOVADRY a benchmark for food safety, and an ideal choice for all food production and clean environment applications.
Uptime upturn
The robust engineering and unique drive-belt technology of the Leybold NOVADRY extends its uptime beyond many other pumps.
End-user driven preventative maintenance is key; using innovative sound analysis technology to judge both belt wear & belt tensioning. Together increasing Total Cost of Ownership.
This technology along with its self-draining pump design make it generally a tougher solution & with a purge gas option and even a flushing kit, can deal with the most challenging of processes.
It delivers consistently high performance for its whole service life across all working pressures, thanks to its wear-free dry screw design.
Pump up the versatility
Vacuum pumps are found in a range of applications, each with its own challenges. The Leybold NOVADRY is built to overcome them all.
In vacuum packaging, frequent pump downs – and the need for the pump to be built-in – can prove too much for some pumps. But the NOVADRY offers short pump down times even under the lowest pressures, while its compact design and optimised noise level make it ideally suited to being built-in.
Vacuum tumbling can increase maintenance requirements for oil-sealed vane pumps, due to aggressive process ingredients, and operating pressures.
However the NOVADRY is designed to handle contaminants such as marinades and oils and with the purge & flush options allowing for the most challenging of processes.
It offers a high, consistent level of performance over a range of operating pressures & being oil-free, there’s no risk of oil backing-up into the tumbler.
In thermoformers, the fast cycle times and variety of packaging (from standard vacuum packs to skin and MAP packs) can be an issue for many vacuum pumps. But the NOVADRY works efficiently for both processes, and guarantees maximum uptime and high yields even for these heavily-used machines.
Vacuum pumps are also found built-in to stuffer machines; though some pumps are unsuited to being integrated in this way, the NOVADRY has been developed specifically for this purpose, with a sturdy dry screw principle which is highly resistant to process media ingestion. 100% oil-free operation also eliminates the risk of oil leakages via the bottom of the stuffer.
So if you’re involved in food production stuffing, thermoforming, or vacuum tumbling or packaging, remember: to keep lubricating oil out of your ingredients, put the Leybold NOVADRY on the menu.
Clean Manufacturing Facility activities
- Clean manufacturing and assembly
- Cleaning products (cleaning baths)
- Clean packaging and labelling (clean packaging areas)
Positive pressurising of the ERIKS clean rooms helps to prevent any ingress of airborne particles, and all technicians working within the rooms change into clean hygienic coveralls and footwear before entering.
Clean rooms meeting the ISO 6 standard, include an airlock, so that people coming into the rooms don’t enter directly from the outside environment. Which means the easiest way to get access to the facilities – and the clean sealing technology products and assemblies they produce – is to contact your usual ERIKS representative and ask where we can help you ensure you are receiving the quality of product and cleaning services expected.
Wake up and smell the coffee
One producer who has realised the benefits of the 100% oil-free NOVADRY vacuum pump is the Caffè Aiello coffee roasting company of Calabria, Italy.
Attracted initially by the smaller footprint and ease of maintenance of the NOVADRY, the company installed the pumps on two production lines, for packaging ground coffee in tins for coffee bars.
The company’s satisfaction with the pumps has encouraged them to commit to replacing at least two other production line vacuum pumps with the Leybold NOVADRY.
