Leybold Interview to Rovagnati
How did the collaboration between Rovagnati and Leybold start?
The collaboration started in the early 90’s, Rovagnati has always been very careful with the choice of its partners and Leybold had been chosen as historical company for vacuum technology in foods and its notoriety and quality of the products.
Which are the essential requirements for the pumps and the vacuum systems used in the food processing?
The pumps need to grant a vacuum value needed for the processes of packaging and tumbling of the cured meats and need to grant repeatable values and maintain them during the production process.
How is a typical vacuum pumping system composed in food processing and why does Rovagnati buy the dry screw pumps DRYVAC?
The system is composed by the piping, the vacuum trap, and the pump. In the packaging process, by the booster
pump and the traditional pump. Rovagnati buys the DRYVAC for its high performance in vacuum, repeatable during time, low maintenance costs and in some applications a considerable energy saving.
Has Rovagnati had a production increase thanks to the system conceived by Leybold? Did Rovagnati achieve savings thanks to this new system?
In some applications we have had a decrease of the time to reach the right vacuum level of approximately 20%, improving the total packaging time.
The first system has been installed 4 years ago and until now we have never had a production stop due to breakdowns or problems.
Rovagnati dedicates maximal attention to the quality of its products. How do you grant it and safeguard it? The use of dry vacuum pumps helps avoiding contamination of the packed product?
The high quality of the products for Rovagnati is a vocation, a precise choice for which we apply a real and sustainable culture of precision, which is implemented in all the productions processes.
Dry pumps vs lubricated pumps: what are the relative advantages for you?
The first one grant low maintenance costs, energy saving and vacuum repeatability.
Why is the vacuum produced by Leybold essential in terms of higher quality?
Leybold pumps help maintain the high quality standard for our products which translates into quality for our consumers.
How are projects handled? How does Leybold take care of the vacuum packaging systems of Rovagnati during their lifecycle?
Rovagnati has an internal maintenance department which handles the ordinary service for the pumps. For the new systems, Leybold provides to Rovagnati all the construction data
for piping and performances.
Service impact: is it quick and up to your expectations?
Until now we never needed it.
