Hygienic Enclosures Ensuring the Highest Hygiene Standards for Vacuum Pumps

Editor: Ahlam Rais

In order to ensure the highest standards of hygiene, food producers and processors are obliged to clean their machinery regularly via washdowns. To guarantee that vacuum pumps are effectively protected from the used aggressive cleaning media, Leybold has developed a series of Hygienic Enclosures. The vacuum specialist offers users these stainless steel housings in seven different sizes, tailor made for each vacuum pump.

In the food industry, vacuum pumps are often placed directly next to the processing and packaging lines and thus not implemented in the equipment. On the one hand, this leads to higher vacuum performance because, losses in pumping speed over longer pipelines are avoided. A direct positive consequence of this, are shorter process cycles and better product quality. On the other hand, unprotected pumps are directly exposed to aggressive cleaning media during rinsing processes. Over time, this leads to corroded vacuum pumps, shorter life cycles, higher costs and ultimately even lead to food contamination.

Effectively Protected in Stainless Steel Enclosures

In order to counteract these risks, the company has developed a new protection concept – the Hygienic Enclosures. Encased by these stainless steel enclosures, the vacuum pumps can be positioned near machines and systems without any problems. On the basis of the protected Leybold vacuum pumps, the company can create better and more robust solutions for demanding food applications. Of course, this applies all the more to applications such as stuffers, tumblers and of course packaging machines, where the machines and systems are cleaned and disinfected particularly frequently and intensively, states the firm.

Specialist Book „Heat Transfer Technique“The comprehensive standard work „Heat Transfer Technique“ offers not only a detailed and well-founded presentation of the basics of heat transfer technique, but also shows the latest state of the art and the latest regulations in the use of organic fluids. Thematically, the book is rounded off with an overview of property data of organic heat transfer fluids as well as many use cases from practical experience.

Tailor Made & Easy to Install

According to the company, these stainless steel enclosures are tailor made for each vacuum pump. As a result each enclosed pump can run constantly on every working pressure. The only limitation is the maximal ambient temperature for the enclosure. Nevertheless, the normal working temperature in F&P environments is around 10 °C and most of the firm’s enclosures offer up to 25 °C. Further all the enclosures are offered as a ‘Do It Yourself’ kit and can be as well installed by the user themselves without great effort. These properties make the Hygienic Enclosures a cost-effective and sustainable solution, adds the company. At the end, Hygienic Enclosures make investments in expensive piping obsolete and at the same moment offer better pumping speed performance.

Sustainable Solution

Incidentally, this also applies to future packaging concepts. The firm believes that the industry is also well equipped for this with new enclosures: Regardless of which solutions will prevail, food applications can be operated more hygienically, ergonomically as well as flexibly from today, mentions the company.
